T-s diagram for the ideal/real ORC. The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, [3] screw, [4] scroll, [5] or other expander), and then through a condenser heat exchanger where it is finally re-condensed.
Orenda Engines was a Canadian aircraft engine manufacturer and parts supplier. As part of the earlier Avro Canada conglomerate, which became Hawker Siddeley Canada , they produced a number of military jet engines from the 1950s through the 1970s, and were Canada's primary engine supplier and repair company.

From January through early August 2017, 39 PW1100G engines versus 396 CFM LEAP engines were chosen. [41] By 2024, the LEAP was selected for 75% of the A320neo orders. [ 40 ] As an example of PW1100G reliability issues, 9% of LEAP-powered A320neos were out of service for at least one week in July 2017, compared with 46% of those using the PW1100G.
These engines include the Stirling engine, hot "gas" turbocharger, and the steam engine. Both range from 10%-20% efficiency, and as of 2014, small quantities are in production for micro-CHP products. Other possibilities include the Organic Rankine cycle, which operates at lower temperatures and pressures using low-grade heat sources. The ...

The Pratt & Whitney JT8D is a low-bypass (0.96 to 1) turbofan engine introduced by Pratt & Whitney in February 1963 with the inaugural flight of the Boeing 727.It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 Intruder and A-4 Skyhawk attack aircraft.
The Honeywell/ITEC F124 is a low-bypass turbofan engine derived from the civilian Honeywell TFE731.The F125 is an afterburning version of the engine. The engine began development in the late 1970s for the Republic of China (Taiwan) Air Force AIDC F-CK Indigenous Defence Fighter (IDF), and it first ran in 1979.
