CFM International announced the RISE program in June 2021 as an intended successor of the CFM LEAP turbofan engine, with plans to enter service in the mid-2030s. At the 2022 Farnborough Airshow in July of that year, CFM International and Airbus announced plans to start flight tests for the RISE engine on an Airbus A380-based testbed in 2026.
The Advanced Turbine Engine Company (ATEC) is a 50/50 joint venture created in 2007 between Honeywell Aerospace and Pratt & Whitney Military Engines. ATEC completed a Core Engine (High Pressure system only) test in mid-2011 on the two-spool HPW3000 and completed Gas Generator (both High and Low Pressure systems) testing in January 2012.
The General Electric T901 (GE3000 [3]) is a turboshaft engine in the 3,000 shp (2,200 kW) class currently under development for the United States Army's Improved Turbine Engine Program (ITEP). The ITEP plans after 2025 to re-engine over 1,300 Sikorsky UH-60 Black Hawk and more than 600 Boeing AH-64 Apache , and was intended to power the now ...
The Boom Symphony is a medium-bypass turbofan engine under development by Boom Technology for use on its Overture supersonic airliner. The engine is designed to produce 35,000 pounds (160 kN) of thrust at takeoff, sustain Overture supercruise at Mach 1.7, and burn sustainable aviation fuel exclusively.
The geared turbofan is a type of turbofan aircraft engine with a planetary gearbox between the low pressure compressor / turbine and the fan, enabling each to spin at its optimum speed. The benefit of the design is lower fuel consumption and much quieter operation.
The LP compressor exit flow passes through passages within the fan disc, directly underneath the fan blades. Some bypass air enters the engine via an auxiliary intake. During take-off and approach the engine behaves much like a conventional turbofan, with an acceptable jet noise level (i.e., low specific thrust).
Heart Aerospace is developing the ES-30, a 30-seat hybrid-electric powered regional airliner, designed for enhanced sustainability and efficiency on short-haul routes.. The ES-30 is projected to have an electric-only range of 200 kilometres (120 mi) and a hybrid-electric range of 400 km (250 mi), significantly reducing CO2 emissions compared to conventional aircraft on similar routes.
The J-2S rocket engine, a cancelled engine developed by NASA, used the combustion tap-off cycle and was first successfully tested in 1969. [2] By 2013, Blue Origin, with their New Shepard launch vehicle, had successfully flight-tested the BE-3 engine using a tap-off cycle. According to Blue Origin, the cycle is particularly suited to human ...
