Gas Turbines For Aircraft Propulsion
Gas turbines are particularly suited for aircraft propulsion because of their favorable power-to-weight ratios. The turbojet engine consists of three main sections: the diffuser, the gas generator, and the nozzle.
Regenerative Gas Turbines With Reheat And Intercooling
Two modifications of the basic gas turbine that increase the net work developed are multistage expansion with reheat and multistage compression with intercooling. When used in conjunction with regeneration, these modifications can result in substantial increases in thermal efficiency.
Simple Gas-Turbine Cycle With A Regenerator 2
The hot turbine exhaust gas has significant thermodynamic utility (exergy) that would be irrevocably lost were the gas discarded directly to the surroundings. One way of utilizing this potential is by means of a heat exchanger called a regenerator, which allows the air exiting the compressor to be preheated before entering the combustor, thereby reducing the amount of fuel that must be burned in the combustor.

Gas Power Systems: Air-Standard Brayton Cycle 2
This topic deals with gas turbine power plants. Gas turbines tend to be lighter and more compact than the vapor power plants studied previously. The favorable power-output-to-weight ratio of gas turbines makes them well suited for transportation applications (aircraft propulsion, marine power plants, and so on).
