You can either sell the cut out projects as your own product or assemble them for your own enjoyment and to give as gifts to your family and friends. In the foreground are the individual cylinder heads with their sealing rings. PTF. At 3,850 rpm with 11 psi (.76 bar) of boost, the engine had a military rating of 2,400 hp (1,790 kW) at sea level, 2,615 hp (1,950 kW) at 2,500 ft (762 m), and 2,045 hp (1,525 kW) at 13,750 ft (4,191 m). The rotational movement of the sleeve crank caused the sleeve to reciprocate and oscillate in the cylinder bore. The design for at least part of the new engine was based on the E101 diesel. One of the Sabre-powered aircraft was lost on 14 September 1944. The engine had a compression ratio of 7.0 to 1. Ultimately, the 539 cu in (8.83 L) Rapier VI (possibly E106) produced 395 hp (295 kW) at 4,000 rpm in 1936, and the 1,027 cu in (16.84 L) Dagger VIII (E110) produced 1,000 hp (746 kw) at 4,200 rpm in 1938. drogue, those Tempests have no trouble giving Linkages were incorporated to allow one lever to control the engines throttle and the propellers pitch along with automatic boost and mixture control, but this system could be overridden by the pilot. The Sabre VA powered the Tempest VI. The Air Ministry enabled the free flow of information between Napier, Halford, and Harry Ralph Ricardoa British engine expert who had been researching sleeve-valve engines for quite some time. Thanks to a complete product portfolio and a full cooling system knowledge, Sogefi designs and provides the right solution for engine temperature management in line with CO2 emission . It had a forecasted output of 4,000 hp (2,983 kW) but was never built. Pre-Owned. A 21-tooth spur gear on the front of each crankshaft meshed with two compound reduction gears, each with 31 teeth. bore and stroke: 152 mm (6 in.) Air was drawn in through a four-barrel updraft SU (Skinners Union) suction carburetor and fed into the impeller. Bengaluru, Karnataka Today Napier is no longer in the engine business, with the ending of the Deltic sales in the 1960s they had no new modern designs to offer. A. Oates, Aircraft Production Volume 6, Numbers 6668 (AprilJune 1944) via The Aircraft Engine Historical Society Two spark plugs mounted parallel to one another in the cylinder head ignited the mixture, initiating the power stroke. Janes All the Worlds Aircraft 1948 by Leonard Bridgman (1948). Carburetor inlets were also relocated to the wings leading edge. The Sabre could be difficult to start, and it was advisable to use a remote heater to pre-heat the coolant and oil in cold temperatures. Fork-and-blade connecting rods were used, with the forked rods serving the three front-left and three rear-right cylinders of the upper banks and the three front-right and three rear-left cylinders of the lower banks. The design concept originated with Harry Ricardo, and a two-cylinder test engine was built in 1942. While testing continued, the Sabre I was first flown in a Fairey Battle on 31 May 1939, piloted by Chris Staniland. It would be interesting to see what date it was published. The engine was 83.0 in (2.11 m) long, 40.0 in (1.02 m) wide, and 47.2 in (1.20 m) tall. transcribed the data points he used, directly Attached to each side of the crankcase was a one-piece, aluminum cylinder block that consisted of an upper and a lower cylinder bank, each with six cylinders. In July 1939, the Air Ministry ordered 100 production engines and material for another 100 engines. Napier produced a wide range of luxury automobiles in a variety of body styles until the early 1920s, when the company shifted into the aerospace engine segment. With the engine technology known in the early 1930s, a perception existed that the poppet-valve engine had reached its developmental peak. More than one attempt was made to revive the Napier car make. Four mounting pads on the underside of the engine attached it to the support structure in the aircraft. The Napier Sabre Engine Parts 13 by J. (Napier/NPHT/IMechE image). Production of the Sabre was halted shortly after the end of World War II with approximately 5,000 engines produced. Speculation on Setwrights 5500hp figure is fun, I have speculated that someone may have told him this was the structural limit of the engine and he either misheard or misunderstood what was said, we will never know. Sleeve trouble came back with Typhoons stationed around Normandy, France in the summer of 1944. While what is in the archives is not complete, Kim puts it all together for a detailed look at the various engine programs. Business listings of Industrial Engines manufacturers, suppliers and exporters in Bengaluru, Karnataka along with their contact details & address. The upper and lower cylinders were numbered 112, starting from the left rear and proceeding clockwise to the right rear. This was a luxury that could not be afforded once the engine was mass produced. If the reported outputs were achieved, it seems they were done in the late 1940s, when many were focusing on other forms of propulsion. Banks then had Bristol produce 48 sleeves for two complete 24-cylinder Sabre test engines. The top ring was later tapered to prevent the buildup of carbon. In August, the Sabre passed a type test with a rating of 1,800 hp (1,342 kW). was rightly critiqued, but he did claim to have As always, a pleasure reading your articles, even for engines that had previously held little interest for me. A centrifugal oil separator was designed to deaerate the oil and was fitted to Sabre engines already installed in Typhoons. Id like to believe it, but I have not seen anything to support those numbers. Boxkite to Jet the remarkable career of Frank B Halford by Douglas R Taylor (1999) By Precision Into Power by Alan Vessey (2007) The drive setup created a double gear reduction, with the compound reduction gears operating at .6774 times crankshaft speed and the propeller shaft operating at .4048 times the speed of the compound reduction gears. Some of the technologies we use are necessary for critical functions like security and site integrity, account authentication, security and privacy preferences, internal site usage and maintenance data, and to make the site work correctly for browsing and transactions. While this helped to prevent failures, it also caused the withdrawal of low-time engines as sleeves became distorted. The engine incorporated contra-rotating propellers and a two-stage supercharger. Napier Flight Development Flight (25 July 1946) On 12 February, an order for 700 Sabre V-powered Tempest Is was issued. Janes All the Worlds Aircraft 1945/46 by Leonard Bridgman (1946) Originally, the company began as an engineering firm, before moving into engines and automobiles in the early Twentieth Century. I am glad you liked the article. Opens in a new window or tab. "Napier Halford" can be seen on the upper camshaft housing. Further to the right is another set of connecting rods that are already attached to the other crankshaft (out of frame). The Tempest V Series I had Hispano Mk II cannons with long barrels that protruded from the wings leading edge. Fighting Boat. I know there were ads for 3,000 hp. Finally, Napier test-ran a Sabre at 4000 hp with ADI. The 3,500 hp achieved at 3,850 rpm with 70.6 in Hg of boost match the Wilkinson values, but I dont know the origins of the 4,000 hp. Rather than being parallel, as in earlier Sabre engines, the electrode of the front spark plug was angled forward, and the electrode of the rear spark plug was angled back. Four aftercoolers were to be installedone on each induction runner leading from the supercharger housing to the intake manifold attached to the cylinder bank. I feel the disappearance of the Flight archive is a tragedy. 1999-2023 PreWarCar.Com @ PreWar PostWar Publishing B.V. - All rights reserved, Website laten maken Vcreations webdesign BV. This aircraft had the larger radiator and wing root carburetor inlets of the Tempest VI, but it did not have the additional oil cooler in the wing. All accessories are mounted neatly atop the engine, away from any leaking oil, coolant, and fuel. Turning off personalised advertising opts you out of these sales. This was still about 75 mph (121 km/h) faster than the aircrafts original design speed. The sleeves were found to be .008 to .010 in (.203 to .254 mm) out of round. I hope that it can return someday. 1 X Product Notes - Letting you know an Approximate Height, Length and Width of your finished product and giving the Approximate Size of the Largest Part. Note the coolant header tank at the front of the engine, the accessories packaged atop the engine, the two-into-one exhaust stacks, and the hydraulic supercharger clutch at the rear of the engine. Halford was already involved in turbojet engine development at de Havilland before his departure from Napier, and some accused him of neglecting his duties on the Sabre. The E113 of 1940 was a fuel-injected, two-stroke, uniflow, Sabre-type test engine intended for increased engine speed and boost. "Nasty Class". The engine was used in later Typhoon IBs and was the main Sabre version to power the Tempest V Series II. In March 1940, Napier created its Flight Development Establishment at Luton, England for flight testing the Sabre and developing installations for the engine. The arrangement provided a much shorter crankcase, a stiffer and simpler crankshaft, and a more compact engine than the 12-cylinder "V" construction of other high-performance engines of the period. I do not intend to write about the Pratt & Whitney H-engines for the reason Tom listed. It's definitely a Must Have for Your Collection! Sandwiched between the crankcase halves was an upper and lower crankshaft, each secured by seven main bearings. In 2016 I was at Burlen Fuel Systems in Salisbury and had a brief look at the SU carburetor used on the early versions of the Sabre. Initially, the Sabre VII had a takeoff rating of 3,000 hp (2,237 kW) at 3,850 rpm with water/methanol injection and 17.25 psi (1.19 bar) of boost. With production engines in production airframes, Sabre reliability issues were soon encountered. of exceptionally high piston speeds quoted in Jumo 213 The first prototype (LA610) made its initial Sabre VII-powered flight on 3 April 1946. Allied Aircraft Piston Engines of World War II by Graham White (1995) The Tempest I was rather elegant without the large chin radiator, and the wing radiators were similar to those that would be used on the Sabre VII-powered Fury. Carbon build-up was causing issues with the lubrication system. I do have one nit to pick, however; the water/methanol injection rates are reported in US and British gallon/hour, but the liter volume is in liters/minute. The Folland Fo.108 was built to Air Ministry Specification 43/37 calling for an engine testbed aircraft. Tempest: Hawkers Outstanding Piston-Engined Fighter by Tony Buttler (2011) requirements at max BMEP outputs for the most Cruise power at 3,250 rpm was 1,750 hp (1,305 kW) at 8,500 ft (2,591 m) for a fuel consumption of .45 lb/hp/hr (274 g/kW/h), and 1,600 hp (1,193 kW) at 17,000 ft (5,182 m) for a fuel consumption of .51 lb/hp/hr (310 g/kW/h). Cruise power at 3,250 rpm was 1,715 hp (1,279 kW) at 6,750 ft (2,057 m) and 1,565 hp (1,167 kW) at 14,250 ft (4,343 m). I did not use Setright as a source as I have always felt the 5,500 hp at 4,200 rpm with 45 psi of boost Sabre claim was too much. The Sabre VA was essentially the production version of the Sabre V. The Sabre VA had a takeoff rating of 2,300 hp (1,715 kW) at 3,850 rpm with 12 psi (.83 bar) of boost. Valve timing had the intake ports opening 40 degrees before top dead center and closing 65 degrees after bottom dead center. Full credit for your authoritative source checking. Napier and Frank Halford The success of the Lion engine and a decline in car sales during the1920s led Napier to concentrate their efforts on aero engines. home | products | search | checkout | contact, 2 or 4 CDR Files - Sizes you receive Depend on individual Product - usually in 1-8 and 3 mm and/or 1-4 and 6 mm Versions (Corel Draw Format for Laser), 2 or 4 DXF's - Sizes you receive Depend on individual Product - usually in 1-8 and 3 mm and/or 1-4 and 6 mm Versions (For Most CAD Programs), 2 or 4 SVG - Sizes you receive Depend on individual Product - usually in 1-8 and 3 mm and/or 1-4 and 6 mm Versions (Opens in Many CAD & Drawing Programs), The Napier Deltic engine is a British opposed-piston valveless, supercharged, uniflow scavenged, two-stroke Diesel engine used in marine and locomotive, applications, designed and produced by D. Napier & Son. I am sorry it took me almost a year to reply to you. Change), You are commenting using your Facebook account.

The annular radiators durability was inadvertently tested on 18 December 1944 when EJ518 made a forced, gear-up landing after a hydraulic failure. recent book which gives a Sabre appraisal from Douglas it would appear, could gain a more useful Napier sought to diversify and expand its aircraft engine business, and the company felt the two-stroke, opposed-piston, diesel engines would usher in an era of safe and fuel-efficient air travel. The Sabre VA weighed 2,500 lb (1,134 kg). Hitherto, in the Royal Navy, such boats had been driven by petrol engines, but their highly, flammable fuel made them vulnerable to fire, unlike the opposing diesel-powered, While the Deltic engine was successful in marine and rail use and very powerful, for its size and weight, it was a highly strung unit, requiring careful. The Sabre V (E107C) was developed from the IV with an updated carburetor. The supercharger clutches were updated and relocated from the extreme rear of the supercharger to between the supercharger and the engine. The propeller shaft, balance beams, and volute springs were secured by the propeller shaft housing that bolted to the front of the engine. It was capable of delivering 8800 GPM of water at 450 psi. Two Battles and three Fo.108s were employed to test the Sabre, and these aircraft provided valuable information about the engine. from United Kingdom Crankcase for a circa 1910 4 cylinder Napier 16,9 hp in good condition / no cracks in aluminium. Twelve exhaust ports were located in a single line on each side of the engine, and each ejector exhaust stack served two portsone for an upper cylinder and one for a lower cylinder. I have spent a bit of time going through my very disorganized collection of information. The worm wheels and their separate housings were mounted to the inner sides of the cylinder blocks. Also mounted atop the engine and geared to the rear of the upper crankshaft was the Coffman combustion starter unit. The Sabre VII ultimately produced 3,500 hp (2,610 kW) at 3,850 rpm with 20 psi (1.38 bar) of boost. The engine powered four English Electric traction motors that gave the locomotive 47,000 lbf (209.1 kN) of tractive effort. This collection of material was compiled on a personal quest to uncover any and all possible information about the PTF. The engine shortage was so severe that a good Sabre would be installed in a Typhoon to ferry the aircraft to a dispersal facility. A drawing of a Sabre II, which was the main production variant.

In 1935, Halford joined Napiers Board of Directors, acting as the companys Technical Director. Possibly removed from aircraft after sale to Amherst Villiers in 1930. As he had done with the Rapier, Halford showed his design to George Purvis Bulman, the Deputy Director of Engine Research and Development for the British Air Ministry. The saddest part of all this is just how little documentation for these British engines has survived. Other aircraft suffered as well. The aircraft is seen here with a large ducted spinner. The aircraft were to serve Napier for several years testing various versions of the Sabre engine. Find here Industrial Engines suppliers, manufacturers, wholesalers, traders with Industrial Engines prices for buying. Each sleeve had only four ports, one of which was used for both intake and exhaust. The BAPC listing, compiled by Peter Kirk in 2003, also has the following: 1064 (Honiton) ATC. The single-piece, six-throw crankshafts were identical, and both rotated counterclockwise when viewed from the rear of the engine. Each worm wheel had an upper and lower sleeve crank, which were phased at 180 degrees. I wonder what technical documentation, if any, survived the cancellation of those projects. (Napier/NPHT/IMechE image). Only around 24 of the Sabre-powered versions were built. Unusually, the cylinders were disposed in a three-bank triangle, with a crankshaft at each corner of the triangle. The Sabre two-cylinder test engine with the Bristol sleeves ran 120 hours without issue. It passes through the two-piece sleeve-valve drive shaft. Aircraft Engines Volume Two by A. W. Judge (1947) on page 477 states: Series VII 3,655 h.p. [7] Bristol became unhappy with sharing its components and processes with a competitor, and Napier was still hesitant to utilize Bristols materials and techniques. Vampires the runaround at low-level!). Around a dozen Sabre engines survive and are on display in museums or held in private collections. I Kept no Diary by F. R. (Rod) Banks (1978) Total Number of Employees. Birmingham MSI (VII) - presumably in store with all their other aero engines. At the center of the radiator is the open carburetor intake, which was later covered by a momentum air filter. Napier continued to develop the engine as the Sabre II, and the first production Sabre II was completed in January 1941. My interest in this is primarily via A.G.M.Michell, a remarkable man. Crankcase for a circa 1910 4 cylinder Napier 16,9 hp in good condition / no cracks in aluminium. I dont recall seeing ads for a 3,500 hp Sabre. It is certain that at Hives RR if such a study was undertaken, a full report would have been written. With the Sabre engines, the Warwicks top speed was limited to 300 mph (483 km/h) due to its fabric covering. The Super Pumper was used from 1965-1982 to supply large amounts of seawater when necessary for fighting fires. All of this equipment was mounted as compactly as possible to the top of the engine. One of the other engines that I am interested is the XB-4070 supercharged diesel barrel engine, I believe that one of these prototype engines still exists. The Hawker Typhoon and Tempest by Francis K. Mason (1988) A single half-sized, turbocharged Deltic power unit also featured in the English, Electric-built Type 2 locomotive, designated as the Class 23. At 3,750 rpm and 9 psi (.62 bar) of boost, the engine had a military rating of 2,235 hp (1,667 kW) at 2,500 ft (762 m) and 1,880 hp (1,402 m) at 15,250 ft (4,648 m). Buy one: Collect them All! An Account of Partnership Industry, Government and the Aero Engine by George Bulman and edited by Mike Neale (2002) In June 1940, the engine passed a 100-hour type test with a maximum output of 2,050 hp (1,529 kW) at 3,700 rpm, making the Sabre the first engine to have a service rating over 2,000 hp (1,491 kW). The Sabre VII was intended to power the Hawker Fury Mk I, of which 200 were ordered in August 1944. Individual ejector exhaust stacks were fitted, replacing the two-into-one stacks previously used on most Sabre engines. Fuel consumption at cruise power was .46 lb/hp/hr (280 g/kW/h). engine became better known as the "Baby Deltic". (He need only compare the boost-level/fuel grade In addition to the Typhoon, the Sabre II also powered the Martin-Baker MB3 fighter, which made its first flight on 31 August 1942, and the Hawker Tempest V fighter prototype (HM595), which made its first flight on 2 September 1942, piloted by Lucas. I have to admit that I can find no evidence for my recollection of the up to 3500hp power rating and must conclude hat I must have been dreaming, most likely I have conflated two different things this, of course, is how these questionable claims start. Maybe a single- or twin-cylinder test engine ran at a pace such that when scaled up to a full engine, those numbers were the mathematical result. Methods were devised to measure the sleeve with special instruments via the spark plug hole. Montague Napier passed away on 22 January 1931, but Nowlan continued design work under the direction of George Shakespeare Wilkinson, Ronald Whitehair Vigers, and Ernest Chatterton. Engine and Spares For Sale Napier turbocharger for sale NA357 Subject: Napier turbocharger for sale NA357 Date: 19.12.2018 15:35:06 Details: Reviews 1 Dear All We have 3 set of Napier turbocharger for sales. As the sleeve rotated back and descended, the cylinders two exhaust ports were uncovered to allow the gasses to escape between the upper and lower cylinder banks. Oil was controlled further by an oil scraper fitted at the bottom of the sleeve between its outer diameter and the cylinder. The " Napier Lion ", the world's first broad arrow engine design, first saw use in 1918 as an advanced 24 litre 12-cylinder "Lion II" broad arrow engine of 450 bhp. The Sabre II produced 2,090 hp (1,559 kW) at 3,700 rpm at 4,000 ft (1,219 m) with 7 psi (.48 bar) of boost and 1,735 hp (1,294 kW) at 17,000 ft (5,182 m). While it is not entirely clear how Banks felt at the time, he later wondered what would have become of the Fairey Monarch H-24 engine if the Air Ministry and the Ministry of Aircraft Production had encouraged its development with the same financial and technological resources supplied for the Sabre. He also fails to acknowledge that the Sabre was Nearly all Sabre I engines were used in Typhoon IAs. This one was a long time coming. Given the Napier designation E101, the engine had a 5.0 in (127 mm) bore, a 4.75 in (121 mm) stroke, and a total displacement of 2,239 cu in (36.68 L). Further, I have been through the listings in the link you provided for the Sabre and quite a few others, most interesting. The Sabre IIA (E115) was a refinement of the Sabre II and had been developed in mid-1943. It would seem that many of these Sabre-related The E109 of 1939 was half of a Sabre, with 12-cylinders and a single crankshaft. To make matters worse, the Typhoon was experiencing its own issues with in-flight structural failures. The Sabre IV incorporated a two-barrel Hobson-RAE injection carburetor and a revised supercharger with a single-sided impeller. Both of these air-cooled engines had a vertical H configuration, with the Rapier having 16-cylinders and the Dagger having 24-cylinders. Wilkinson took out a patent for the sleeve drive (GB363850, application dated 7 January 1931), and Vigers took out patents for sealing rings on a plug-type cylinder head (GB390610, application dated 15 February 1932) and sleeve-valves (GB408768, application dated 24 January 1933). The Sabre VII weighed 2,540 lb (1,152 kg). HIGHEST SALE $418,783. maximum power (combat rating) at 3,850 R.P.M at 2,250 ft. altitude with moderate supercharge. I include this source as an example that I was not just blindingly including numbers. Each cylinder displaced 93.2 cu in (1.53 L), and the engines total displacement was 2,239 cu in (36.68 L). accommodating very high rpm (Roy Fedden stated he Aircraft Engines of the World 1949 by Paul H. Wilkinson (1949) By the end of 1966 Napier's Liverpool Works had manufactured its 500th Deltic. The Sabre VIII (E122) Series engine of higher boost with 2 stage 3 speed Supercharger, contra rotating propellers and fan drive engine capable of 3,350 B.H.P. The first production Typhoon IA (R7576) flew on 27 May 1941, with other aircraft soon to follow. (AEHS image). The engine was selected for the Tempest I, the prototype of which was initially ordered on 18 November 1941, followed by an order for 400 production aircraft in August 1942. Bird, Bat & Butterfly Houses & Bird Feeders. The spark-ignition engine had a similar layout to the E101 dieselboth being liquid-cooled H-24s with sleeve-valves and possessing the same bore and stroke. Do you intend on writing an article on the P&W liquid cooled sleeve valve H engines? The top of the sleeve extended between the cylinder head and the cylinder wall. The issues with sleeve distortion were the most serious and vexing. Compared to the Sabre IIA, the IIB used a different carburetor, had a modified boost controller, and was cleared for additional engine speed. Helical grooves inside the lower part of the sleeve helped prevent excessive oil accumulation on the sleeve walls. 1979. Next is an upper accessory housing with some accessories attached. Year of Establishment. The Deltic story began in 1943 when the British Admiralty set up a committee to, develop a high-power, lightweight Diesel engine for Motor Torpedo Boats. The lower auxiliary drive shaft powered left and right coolant pumps, a fuel pump, and various oil pumps. Cutaway drawing of a Sabre VA illustrating the engines propeller reduction gears and sleeve-valve drive. The boost controllers were factory sealed, and severe repercussions were put in place for their unauthorized tampering. With the Air Ministrys push, Napier was taken over by English Electric in December 1942. settings/time periods, and volumetric efficacy of Banks suggested that Napier work with the Bristol Engine Company on a suitable sleeve for the Sabre. In 1984 I stood next to the Sabre engine on display at the RAF Museum Hendon ( now London I think ) for some time, amazed at the complexity of it. With the exception of a few installed studs, the left and right cylinder blocks were interchangeable. This order was temporarily suspended due to the Battle of Britain but was reinstated in October 1940. The center main bearing was larger than the rest, which resulted in an increased distance between the third and fourth cylinders in each bank. Hello and thanks for shopping with Makecnc! Napier Sabre II by F. C. Sheffield, Flight (23 March 1944) I was trying to estimate the heat rejection of the engine if it was to produce that sort of power for any length of time, the mind boggles. Hundreds of observers had their cameras focused on the chorus . Napier Deltic Engines Search There are currently no Napier Deltic Engines listed on Diesel Engine Trader Customer Testimonials 'We bought a new John Deere engine via DieselEngineTrader.com for a great price and were able to sell it locally for $1000 less than our competition. Len Setrights emotive/enthusiastic writing style Stamped 17832 E445 also cast 09152 into right rear arm. Change). Around 1940, consideration was given to producing the Sabre in the United States. Napier engine-s (and parts) for Napier. Three of the fixed-gear monoplanes were delivered to Napiers Flight Development Establishment at Luton in 1941 and were initially fitted with Sabre II engines. Although some sources say the Sabre VIII was built, it appears to have remained an unbuilt project. Please See our Tutorial for information on dealing with Inside Corners and Dogbone Fillets, Printable PDF Pattern (For Scroll Saw Use). ALL DOWNLOADABLE PRODUCTS ARE AVAILABLE INSTANTLY AFTER PAYMENT! The Tempest V was a new aircraft developed from the Typhoon. The cylinder housing for the five-cartridge Coffman starter can be seen above the supercharger. was incredulous on 1st principles, about this claim). Janes All the Worlds Aircraft 1947 by Leonard Bridgman (1947) These early engines were limited to 25 hours before being removed for major inspection. The superchargers centrifugal impeller was double-sided. Installed in the Napier-Heston Racer, the combination first flew on 12 June 1940, piloted by G. L. G. Richmond. This setup enabled the sleeves to operate at half crankshaft speed (and half the speed of the sleeve-valve drive shaft). The starter had a five-cartridge capacity. The water/methanol injection lowered the engines tendency toward detonation and allowed for more power to be produced. Not nearly as great of a tragedy as all the company archives that were discarded with a change in ownership or location, but still a tragedy. A number of engine designs based on the Sabre were considered, but most stayed as projects, and none progressed beyond cylinder testing. The Coffman cartridge starter caused other issues; its sudden jolt when starting the engine occasionally damaged sleeve-drive components, setting up their inevitable failure.
