WebThe bypass ratio ( BPR) of a turbofan engine is the ratio between the mass flow rate of the bypass stream to the mass flow rate entering the core. [1] A 10:1 bypass ratio, for example, means that 10 kg of air passes … Webcomes out to 0.026. If an engine had a thrust-to-engine-weight of 75, that would be a C F of approximately 0.0133. So, since the stage thrust drives more masses than just the engine (like thrust take-out structure and perhaps tank skin thickness), a value for C F representing up to 2x or 3x of engine weight would seem reasonable, as seen here. =

WebNov 4, 2024 · The power/weight ratio can be expressed as follows: 0.5: 1 means that the thrust is half the weight, with this in mind, for gliders or light and slow-flying model aircraft, a ratio of between 0.3: 1 to 0.4: 1 on trainer models from 0.5: 1 to 0.8: 1 and on fast models from 0.8: 1 onwards. WebOct 8, 2024 · A rocket's overall thrust-to-weight ratio is much less often quoted. It will generally be less than 10 (except in a few very unusual cases). It usually starts at somewhere between 1.2 and 1.5 at liftoff, increasing over the course of a stage's burn, as propellant is consumed; it varies with payload and mission.
