The General Electric I-A was the first working jet engine in the United States, manufactured by General Electric (GE) and achieving its first run on April 18, 1942.. The engine was the result of receiving an imported Power Jets W.1X that was flown to the US from Britain in 1941, and the I-A itself was based on the design of the improved Power Jets W.2B, the plans of which were also received.
A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket , water jet , and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet , turbofan ...
Planes built from metal use similar techniques to more conventional factory-built aircraft. They can be more challenging to build, requiring metal-cutting, metal-shaping, and riveting if building from plans. "Quick-build" kits are available which have the cutting, shaping, and hole-drilling mostly done, requiring only finishing and assembly.

A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in pulses.A pulsejet engine can be made with few [1] or no moving parts, [2] [3] [4] and is capable of running statically (that is, it does not need to have air forced into its inlet, typically by forward motion).
Data from Jane's General characteristics Type: centrifugal flow turbojet Length: Diameter: Dry weight: 700 lb (320 kg) Components Compressor: single-stage double-sided centrifugal flow Combustors: 10 reverse-flow Turbine: single stage axial flow Fuel type: kerosene Performance Maximum thrust: 850 lbf (3.8 kN) at 16,500 rpm Air mass flow: 20.6 lb/s (9.3 kg/s) Fuel consumption: 1,170 lb/h (531 ...
One was the jet-powered BD-5J, which boosted performance to 305 knots (565 km/h; 351 mph). [1] There was an attempt to sidestep the engine problem with the BD-5S glider (S for Sailplane), with lengthened wings and no engine, which prompted Air Progress magazine to sarcastically note, "At last, a BD-5 with no engine problems."
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
