A turbine represents a simple but effective way to harness energy by changing the force of a moving fluid into circular motion. Gas turbines are essentially a refinement of an ancient technology that underwent a rapid development in the nineteenth and...

The aircraft gas turbine engine, developed more than sixty years ago, uses the principle of jet reaction and the turbine engine. The engine consists of three major elements: a compressor and a turbine expander, which are connected by a common shaft;...

A gas turbine extracts energy from a flow of hot gas produced by combustion of gas or fuel oil in a stream of compressed air. It has an upstream air compressor (radial or axial flow) mechanically coupled to a downstream turbine and a combustion chamber...

Scientist at the Gas Turbine Laboratory of the Massachusetts Institute of Technology are using silicon microfabrication methods in their efforts to develop a gas turbine engine that weighs one gram. Issues such as face-area-to-volume ratios, chemical reaction times and electric-field strength are the factors...

We continue with our discussions from previous columns with tables suggesting preferred groups or suites of tests for routine monitoring of various components used in specific applications. In the November 2005 TLT, we looked at tests done on diesel engines. This month we focus...
