turbine compressor
41single-spool compressor — A single compressor rotor design of the axial flow type. A single spool compressor will have a single turbine wheel …
42air-cooled turbine blades — The hollow turbine blades of some engines, cooled by air flowing through them that is bled from the compressor. Air cooled by convection turbine blade …
43expansion turbine — A turbine wheel in an air cycle air conditioning system used to extract some of the energy from the expansion gases. The expansion turbine helps drive the air compressor …
44gas turbine numerology — All gas turbine engines, except those with bypass ducts, are given station designations from 0 to 9, with the station 0 denoting the area ahead of the inlet where the airflow is undisturbed and the number 9 denoting the exhaust flow conditions of …
45high-pressure turbine — The turbine used to drive a high pressure (N2 ) compressor. In a twin spool engine, it is positioned just after the combustion chamber turbine …
46power turbine — An arrangement in which the turbine is not connected to the compressor. Also known as a free power turbine …
47gas turbine engine — gas turbine engine, an engine that utilizes a gas turbine to generate mechanical power, especially to turn the compressor in a jet engine or the generators used in a jet aircraft …
48split-compressor engine — A gas turbine engine that has two compressors running at two different speeds. The compressors may be both axial or a combination of centrifugal and axial. N1 and N2 are RPMs of low and high pressure compressor, respectively …
49coupled power turbine — A type of turboprop engine. In this arrangement, the gas flow is fully expanded across a turbine, which drives the compressor. The developed surplus power is transmitted to the propeller by a common driveshaft via suitable reduction gearing …
50radial inflow turbine — A turbine wheel that receives its gases at the blade tips and guides the air inward and outward to the extreme duct. It is used generally in auxiliary power units, or APUs. It looks similar to a radial compressor …
