In a twin spool engine
WebA twin spool counter-rotating turbofan gas turbine engine having a counter-rotating fan module integrated with the high pressure compressor and driven by a counter-rotating turbine utilizing only two drive shafts. The two drive shafts are aerodynamically coupled and rotate in opposite directions relative to each other with or without the use of a gearbox. WebTwin-spool jet engine (top) compared with a conventional design (below). Note that the twin-spool version has two compressors, each driven by its own turbine. This arrangement gave more thrust with better fuel …

Turbofan engines come in a variety of engine configurations. For a given engine cycle (i.e., same airflow, bypass ratio, fan pressure ratio, overall pressure ratio and HP turbine rotor inlet temperature), the choice of turbofan configuration has little impact upon the design point performance (e.g., net thrust, SFC), as long as overall component performance is maintained. Off-design performance and st…
WebThe Pratt & Whitney J58 (company designation JT11D-20) was a jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. The J58 was a single-spool turbojet with an afterburner. It had a unique bleed from the compressor to the afterburner which gave increased thrust at high speeds.

WebSep 17, 2024 · The purpose of twin-spool designs is to allow the different assemblies to rotate at different speeds. Higher compression stages need less frontal area than lower compression stages. At the same time, the blade tip speed of every state should always be subsonic. What is a single spool compressor?
