NASA Uses Small Engine to Enhance Sustainable Jet Research
Apr 29, 2024. Article. The DGEN380 Aero-Propulsion Research Turbofan (DART) is a small-scale jet engine NASA uses to test new aviation technology. DART is seen here inside its host facility, the Aero-Acoustic Propulsion Laboratory at NASA's Glenn Research Center in Cleveland. This soundproofed chamber ensures researchers can understand the ...
Aircraft engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. ... Munich-based research institute de:Bauhaus Luftfahrt presented a high-efficiency composite cycle engine for 2050, combining a geared turbofan with a piston engine core.
Recent advances in the development of aerospace materials
Despite the attractiveness of alphas titanium alloy, some research [14, 57] has shown that alpha phase can greatly limit the high-temperature capability of titanium alloys. Fortunately, the alpha stabilizing additions enable these alloys to serve in aircraft jet engines in which the temperature can reach up to 600 °C.

Recent research progress on airbreathing aero-engine ...
Because the research time is longer than that of other airbreathing engines, the control of aircraft gas turbine engines (GTEs) is more mature. In 1987, the integrated high performance turbo engine technology (IHPTET) program was launched to double the engine's thrust-to-weight ratio and increase the combustor temperature by 222 °C [ 9 ].
