 Allison Engine Company - Wikipedia, the free encyclopedia
It is best known for the Allison V-1710 V-12 engine, which was the only high-powered U.S. liquid-cooled inline engine design to see use during World War II.
Allison tried again with the Allison T56, basically an enlarged T38 with the power of the T40, and was eventually rewarded when this engine was selected to power the C-130 Hercules.
Allison also started the development of a series of turboprop engines for the U.S. Navy, starting with the T38 and a "twinned" version as the T40.

 Allison V-1710 - Wikipedia, the free encyclopedia
The Allison V-1710 aircraft engine was the only indigenous US-developed liquid-cooled engine to see service during WWII.
The Allison Division of General Motors began developing the ethylene glycol (Prestone) cooled engine in 1929 to meet a US Army need for a modern, 1000 horsepower (750 kW), engine to fit into a new generation of streamlined bombers and fighters.
Early in the war Allison approved War Emergency ratings to be used in combat that allowed engines rated for takeoff at 1,150 hp (860 kW) to operate at up to 1,600 hp (1,200 kW), but required immediate disassembly and inspection of the motor before reuse.

Allison proposed such a variant, the V-1710-127 (-E27), to power the Bell XP-63H, with a General Electric CT-1 turbine, based on the CH-5 turbocharger used in P-47M and Ns.
However, the first two-stage Allison to incorporate an aftercooler was the V-1710-119 (-F32R) which powered North American's XP-51J to a speed of 471 mph at 27,400 feet in the spring of 1945.
During the war, Allison had studied the use of turbocompounding, where the energy lost to the engine's exhaust was partially recovered by a gas turbine and fed directly back into the engine through reduction gearing.

 Allison V1710 Engine
Allison developed the "E" series of engines to accommodate the engine location -- the power section was adopted from the "F" series, with propeller reduction gear removed and a crankshaft-driven shaft passing under the cockpit to a remote gear-reduction unit with a hollow passage for the cannon through the center of the propeller shaft.
Allison, which became a part of general motors in 1929, invested private funds in the development of a liquid-cooled V12 engine at the urging of Allison General manager Norm Gilman.
The engine power would be transmitted by 16' driveshafts to the remote transmission and gear arrangements in the swiveling heads.

 Bell P-39M Airacobra - Variants
The powerplant of the XP-39 was the 1,150 hp (858 kW) Allison V-1710-17 l2-cylinder liquid-cooled Vee piston engine which was fitted with a B-5 supercharger on the port side of the central fuselage.
The 1,150 hp (858 kW) Allison V-1710-17 of the XP-39 was replaced by a non-supercharged Allison V-1710-39 engine rated at an altitude of 13,300 feet.
The engine was the 1,200 hp (895 kW) Allison V-1710-85, the same powerplant that was used in the P-39N.

 [1.0] The Allison Mustangs
The A-26 was powered by an uprated Allison V-1710-87 engine, with 1,325 horsepower at low altitude.
The Allison Mustangs did not do well in the air combat role, as they were at a disadvantage against their primary adversary, the agile Nakajima Ki-43 Hayabusa, known to the Allies as the "Oscar".
By March 1944, roughly half of the Allison Mustangs operated by the USAAF in Italy would be gone due to various causes, and the rest would be replaced by July 1944.

Allison made a good dirigible power plant and awarded a development contract to the Indianapolis firm.
The target was 1,000 hp, and Allison intended that the engine should be large enough to deliver this power easily.
Around the time that the Army was washing its hands of the Curtiss Conqueror, Allison began to develop its own engine.

Allison V-1710's were used to power the Lockheed P-38, Bell P-39 Aircobra, P-63 Kingcobra, Curtis P-40 Warhawk and early versions of the P-51 Mustang.
The Allison V-1710 was the only American built, liquid-cooled engine to see service during WW II.
Originally developed to power dirigibles, the design was modified in 1935 for use in aircraft.

(P-38L) Two 1,475 hp (1100 kW) Allison V-1710-111/113 engines.

The Allison V-1710 engine which powered the P-39, P-63 and other fighters was designed from the beginning to use a turbosupercharger to boost its power at altitude, and when so fitted, as in the P-38 Lightning, gave excellent service.
Allison’s answer to this problem was the P-63A’s 1,325 horsepower V-1710-93 engine, which featured a second, auxiliary supercharger with an automatic hydraulic drive.
Key points in common were the Allison V-12 engine mounted behind the cockpit, 37mm cannon in the nose and automotive style doors on each side of the pilot’s compartment.

 [3.0] The Twin Mustang / Postwar Mustangs
Two of the flight prototypes were designated "XP-82s" and were to be powered by variants of the Packard V-1650 Merlin, and two were designated "XP-82As", to be powered by variants of the improved Allison V-1710-119 engine with two-stage supercharging.
There were few other reasons to use the Allison engine, since even the two-stage supercharged Allison V-1710 was inferior in power-to-weight ratio to the Merlin.
As it turned out, investigation of the relatively obscure Allison Mustangs (which were important aircraft in their own right) and the Twin Mustang was good fun, as was finding out that the P-51, from first glance the most American of aircraft, was hardly a purely American invention.

 ::Warbird-Central.com :: Warbird Information Database
With the promise from Allison that an internal supercharger could be fitted to the V-1710, the 10th P-36A was used.
With the standardization of the Allison V-1710, the P-36 design was reworked to incorporate this engine, this resulted in three new designations of XP-37, YP-37, and XP-40.
The first, XP-40Q-1, was a converted P-40K with a 1425 hp V-1710-121 Allison with a two-stage supercharger and a four bladed prop for increased altitude performance.

 Rolls-Royce Merlin - Wikipedia, the free encyclopedia
The V-1650 preformed so much better than its US counterpart (the Allison V-1710) that it would eventually replace that engine in the P-51 Mustang, which then went to be viewed as one of the best fighters of the war.
The Merlin was a 12 cylinder, 60° "V", 27 litre, liquid cooled piston aircraft engine built during World War II by Rolls-Royce.
When this was no longer an issue in 1943, the Packard company started production in the US as the V-1650, originally for use in US-built Spitfires.

The Allison V-1710 was the only U.S. liquid-cooled production engine of World War II and the first engine designed from the start to use ethylene glycol (prestone) coolant.
Lack of an adequate supercharger inhibited high-altitude performance; however, around 47,000 were built by the end of World War II.
Design began in 1930 to replace the Maybach engines used by the U.S. Navy's airships.

These aircraft would be powered by an Allison V-1710 engine as the X-1800-A3G never materialized.
Instead, Curtiss redesigned the P-40, installing a new Allison V-1710-39 which made it's rated power to 11,700 feet.
During the process of testing the YP-37 fighters, Curtiss took the tenth P-36A from the production line and, removing the R-1830 radial engine, installed an Allison V-1710-19.

P-40M, version generally similar to the P-40K, with a stretched fuselage like the P-40L and powered by an Allison V-1710-81 engine giving better performance at altitude (compared to the previous Allison versions).
With a new, larger Allison engine, slightly narrower fuselage, redesigned canopy, and improved cockpit, the P-40D eliminated the nose-mounted.50 cal guns and instead had a pair of.50 cal (12.7 mm) guns in each wing.
The P-40N featured a stretched rear fuselage to counter the torque of the larger, late-war Allison engine, and the rear deck of the cockpit behind the pilot was cut down at a moderate slant to improve rearward visibility.

 P-38: Der Gabelschwanz Teufel
The February, 1937 Circular Proposal X-608 (ie RFP) for a single and a twin engine fighter called for the use of the very new Allison V-1710 inline liquid cooled V- 12, equipped with the new GE turbocharger for high altitude performance, and for the use of very heavy armament including cannon.
The Allisons misbehaved quite consistently, 'throwing rods, swallowing valves and fouling plugs' while the intercoolers often ruptured under sustained high boost, and turbocharger regulators froze at 10 in.
Fuel too, was a source of trouble, it is believed by many knowledgeable people that the majority of fuel used in Britain was improperly blended, the anti-knock lead compounds coming out of solution (separating) in the Allison's induction system at extreme low temperatures.
