Instead of the cyclic nature of the piston engine, the gas turbine uses a continuous system especially valuable in aircraft as it is vastly lighter than an equivalent piston engine though at some sacrifice of thermal efficiency.

A range of gas turbine cycles, from simple closed cycle engines to more complex regenerated and reheated cycles are considered. It is shown that the basic Joule cycle has an efficiency equal to a Carnot cycle operating between the average temperatures of energy addition and rejection: a concept that also applies to the more complex cycles.

ABSTRACT The use of surface coatings, which are applied to the hot-end components of the modern gas turbine to protect against oxidation and/or corrosion, is commonplace and the correct choice of coating process is a balance between cost effectiveness, operational environment and lifetime.

The cooling of turbines offers the alternative advantages of the use of higher cycle-maximum-temperatures than are possible with uncooled turbines, with consequent increase of thermal efficiency and power output for a given size of compressor, or the use of lower quality materials for a given turbine inlet-temperature.

Physics Education, 2003 Gas turbine engines power most commercial flights operating today. Yet many people are ignorant of the cutting-edge technologies used in the creation and operation of these engines. This article explains some of the principles involved with emphasis on the selection of materials for fan blades and turbine blades, which have to operate reliably in ...

Publisher Summary This chapter discusses advantages of gas turbines. The main advantage of gas turbines lies in the large volume flow rate and the resulting large power with small dimensions and small cost of material. In piston engines the speed of the piston is limited for various reasons (effects of inertia, flow losses, lubrication problems); this

Due to the high power compared to weight and volume, gas turbines are very suitable components of aircraft propulsion systems. Almost all modern aircraft propulsion is gas turbine based. Only with low power (< 300 kW), as for very light aircraft, are reciprocating engines used. Aircraft propulsion systems exist in a wide variety of types.

, 1996 This book focuses on the design of regenerators for high-performance regenerative gas turbines. The ways in which gas-turbine regenerators can be designed for high system performance can be understood by studying gas-turbine cycles, the thermodynamic cycles by which gas turbines convert heat into work. This chapter introduces gas-turbine cycles.
