Exchanger, the weight is increased significantly. As a result, this type of gas turbine is not used for aircraft, although it has many important ground applications, including electric power generation. 3. 14. For this cycle, the working gas is first compressed by a "low-pressure" compressor, which increases the pressure to an intermediate value. Next, the gas is cooled, reducing the temperature of the gas. The gas is then further compressed until it reaches the nominal pressure. As will be shown through cycle analyses (Chapters 2 and 3) as well as a consideration of compressor design fundamentals (Chapter 6), decreasing the temperature of the gas reduces the power required to increase the pressure to a given level.
The maiden voyage of the V2 occurred in 1940, and its introduction allowed for previously unattainable long-range delivery of warheads. rocket technology and is still the basic operating principle for modern rocketry. In 1942, General Electric (GE) developed what is considered the first Americanjet engine, the GE I-A. This was a small engine that generated 1300 lbfofthrust and was a copy of the early Whittle engine. 8 General Electric J-31 (courtesy of Wright Patterson Air Force Base (WPAFB)). 5 Whittle's WUl jet engine (from Fig.
