WebApr 13, 2024 · Plane Crazy talk focuses on GE-36 engine. Retired General Electric chief test pilot Phil Schultz will speak Saturday at the Mojave Air and Space Port about the flight test development of GE’s experimental unducted fan airplane engine, tested in the mid-1980s as a potentially more fuel-efficient means of aircraft propulsion. WebA turbofan is a turbine engine having a large low-pressure fan ahead of the compressor section; the low-pressure air is allowed to bypass the compressor and turbine, to mix with the jet stream, increasing the mass of accelerated air. This system of moving large volumes of air at a slower speed raises efficiency and cuts both fuel consumption ...

WebA propfan, also called an open rotor engine, or unducted fan (as opposed to a ducted fan), is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from both. The design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop. WebApr 8, 2024 · Gas turbine fuel burn for an aircraft engine can be obtained analytically using thermodynamic cycle analysis. For large-diameter ultra-high bypass ratio turbofans, the impact of nacelle drag and propulsion system integration must be accounted for in order to obtain realistic estimates of the installed specific fuel consumption. However, simplified …
