General Electric J31
The General Electric J31 was the first jet engine to be mass-produced in the United States. Design and development After a visit to England mid-1941, General Henry H. Arnold was so impressed by flight demonstrations of the Gloster E.28/39 jet aircraft he had witnessed that he arranged for the Power Jets W.1X turbojet engine to be shipped by air to the U.S, along with drawings for the more powerful W.2B/23 engine, so that the US could develop its own jet engine. General Electric's extensive experience in turbocharger production made them the natural choice for producing such an engine. The initial prototype, the General Electric I-A, was essentially based on the W.2B/23. It first ran on 18 April 1942 and developed a static thrust of 1250lbf. The I-A air intake consisted of two peripheral slots which led to a double-sided, centrifugal compressor. A series of vanes guided the air into the impeller eyes. After radial compression, the air was diffused and turned 90 degrees rear ...

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Allison Engine Company
The Allison Engine Company was an American aircraft engine manufacturer. Shortly after the death of James A. Allison, James Allison in 1929 the company was purchased by the Fisher Body, Fisher brothers. Fisher sold the company to General Motors, which owned it for most of its history. It was acquired by Rolls-Royce Holdings, Rolls-Royce plc in 1995 to become the US subsidiary, Rolls-Royce North America. History A predecessor of Allison Engine Company, the Concentrated Acetylene Company, was founded in September 1904 by James Allison, Percy C. Avery, Percy C. "Fred" Avery and Carl G. Fisher. Avery was the holder of the patent for the product. This company was the predecessor of the Prest-O-Lite, Prest-O-Lite Company, a manufacturer of acetylene headlights. An explosion at the acetylene gas works in downtown Indianapolis caused the company to relocate out of town, near the race track in Speedway, Indiana. Allison and Fisher raced automobiles at that track, each owning a race car t ...

De Havilland Goblin
The de Havilland Goblin, originally designated as the Halford H-1, is an early turbojet engine designed by Frank Halford and built by de Havilland. The Goblin was the second British jet engine to fly, after Whittle's Power Jets W.1, and the first to pass a Type certificate, type test and receive a type certificate issued for an aircraft propulsion turbine. Although it was conceived in 1941 it remained unchanged in basic form for 13 years by which time it had evolved to the Mk. 35 export version. The Goblin was the primary engine of the de Havilland Vampire, and was to have been the engine for the F-80 Shooting Star (as the Allis-Chalmers J36) before that design switched engines due to production delays at Allis-Chalmers. The Goblin also powered the Saab 21R fighter, Fiat G.80 trainer and the de Havilland DH 108 "Swallow" experimental aircraft. The Goblin was later scaled up as the larger de Havilland Ghost, with the model numbers continuing from the last marks of the Goblin. ...

Combustor
A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, the ''combustor'' or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands. The burned mix is exhausted from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the exhaust is directly fed out through the nozzle. A combustor must contain and maintain stable combustion despite very high air flow rates. To do so combustors are carefully designed to first mix and ignite the air and fuel, and then mix in more air to complete the combustion process. Early gas turbine engines used a single chamber known as a can-type combustor. Today three main configurations exist: can, annular, and c ...

Ryan XF2R Dark Shark
The Ryan XF2R Dark Shark was an American experimental aircraft built for the United States Navy that combined turboprop and turbojet propulsion. It was based on Ryan Aeronautical's earlier FR Fireball, but replaced the Fireball's piston engine with a turboprop engine. Design and development The XF2R Dark Shark was based on Ryan Aeronautical's earlier FR Fireball, but replaced the Fireball's piston engine with a General Electric T31 turboprop engine driving a 4-bladed Hamilton Standard propeller. The turboprop made for much improved performance over the Fireball, but the Navy showed little interest in it; by that time, they had abandoned the idea of the combination fighter and were instead looking into all-jet fighters. The United States Air Force, however, showed a little more interest; they were at the time evaluating the Convair XP-81 of similar concept, and asked Ryan to modify the XF2R to use the Westinghouse J34 turbojet instead of the General Electric J31 used previously ...
