An even larger engine will also be made, with a 52 in (130 cm) fan. The BR710 and BR715 main developments, the next generation of 44–89 kN (10,000–20,000 lbf) engines to be introduced in the 2020s, will have an Advance 3 core, improved engine health management, newer materials, and cooling.
The CFM56 is a high-bypass turbofan engine (most of the air accelerated by the fan bypasses the core of the engine and is exhausted out of the fan case) with several variants having bypass ratios ranging from 5:1 to 6:1, generating 18,500 to 34,000 lbf (80 kN to 150 kN) of thrust. The variants share a common design, and differ only in details.
The CFM International LEAP ("Leading Edge Aviation Propulsion") is a high-bypass turbofan engine produced by CFM International, a 50–50 joint venture between American GE Aerospace and French Safran Aircraft Engines. It is the successor of the CFM56 and competes with the Pratt & Whitney PW1000G to power narrow-body aircraft.
The GE Passport is a high bypass ratio turbofan. The engine is a twin-spool, axial-flow turbofan with a high bypass ratio of 5.6:1 and an overall pressure ratio of 45:1. The front fan is attached to the three-stage low-pressure compressor; the 23:1 pressure ratio 10-stage high-pressure compressor includes five blisk stages for weight reduction.
The two-shaft turbofan has a high-pressure core from the PS-12 with an eight-stage compressor and a two-stage turbine, and four low-pressure stages. The high-bypass engine does not employ an exhaust mixer, fuel burn should be reduced by 10–15% from the CFM International CFM56 and it could power an upgraded Tupolev Tu-204. [citation needed]
The essential mechanical components of a Stirling cryocooler are identical to a Stirling engine. In both the engine and the heat pump, heat flows from the expansion space to the compression space; however, input work is required in order for heat to flow "uphill" against a thermal gradient, specifically when the compression space is hotter than ...
Premium efficiency, when used in reference to specific types of Electric Motors (with a rotating shaft), is a class of motor efficiency.. As part of a concerted effort worldwide to reduce energy consumption, CO 2 emissions and the impact of industrial operations on the environment, various regulatory authorities in many countries have introduced, or are planning, legislation to encourage the ...
