Gas turbine engine test 2 lectures Flashcards Quizlet

A type of compressor used in a turbine engine in which the airflow through the compressor is essentially linear. An axial-flow compressor is made up of several stages of alternate rotors and stators. The compressor ratio is determined by the decrease in area of the succeeding stages. What is the functional elements in a centrifugal compressor?

Centrifugal compressors are used to power gas turbine engines used in jet aircraft, energy production, and other heavy industry applications. In a gas turbine, the centrifugal compressor transfers energy from impeller blades. Many factors affect compressor and turbine engine performance, including blade dynamics, fluid dynamics, and the physical properties of gas.

Early gas turbines employed centrifugal compressors, which are relatively simple and inexpensive. They are, however, limited to low pressure ratios and cannot match the efficiencies of modern axial-flow compressors. Accordingly, centrifugal compressors are used today primarily in small industrial units. An axial-flow compressor is the reverse of a reaction turbine.

Matching Gas Turbines and Centrifugal Compressors

Gas turbine-driven centrifugal compres-sors are broadly employed in the oil and gas industry for semi-constant or variable compression duty applications as depicted in Figure 1. Semi-constant duty services tend to fall between two operational extremes: Narrow speed range or narrow flow range and power. Examples may be found in downstream ...

Centrifugal Stress - an overview ScienceDirect Topics

In gas turbines, first-stage blades operate at high temperatures (1150 C) and high centrifugal stresses. Centrifugal stresses can reach up to 250 MPa and thermal stresses can fluctuate from −350 to 500 MPa. Nozzle guide vanes operate at high temperatures and are subjected to bending stresses induced by gases.

The centrifugal-axial flow design uses both kinds of compressors to achieve the desired compression. The path the air takes through the engine and how power is produced determines the type of engine. Four types of gas turbine engines are used to propel and power aircraft. They are the turbojet, turbofan, turboprop, and turboshaft. Turbojet

THE first gas turbine propelled aircraft in this country were the result of Whittle's classic conception using a single‐stage centrifugal compressor. On the other hand the German turbo‐jets had, without exception, multi‐stage axial compressors. The two types are shown diagrammatically in FIG. 1 and the outstanding differences are apparent at a glance.
