WebIncreasing the bypass ratio of a high-bypass engine even further yields diminishing returns, which tend to be compensated by the increased nacelle drag once the bypass ratio grows beyond 12 to 15. To make bigger bypass ratios economical, active laminarisation on the nacelle will be needed.

WebDec 20, 2014 · High-bypass turbofan engines do not create condensation trails. The ratio of air-to-exhaust is much too high to facilitate the formation of condensation because the majority of air expelled from the back of the engine is not combusted. It is passed through the "fan" and simply blown out the back without mixing with any fuel at all. WebJul 5, 2024 · Turbofan example. To get a feel for typical working temperatures and pressures through the various stages of a jet engine, consider the figure below, which shows a cross-section of the Pratt and Whitney JT9D-7 high-bypass turbofan engine. The JT9D-7 powered the original Boeing 747 when it entered service in 1970.
