Your inputs on the following is greatly appreciated. 1) A definition of the term OVERBOOSTING. 2) The conditions which will lead/ may lead to overboosting a high-bypass. turbofan engine ( e.g neglecting to apply proper bleed correction to epr. values at a certain phase) Engines with more jet thrust relative to fan thrust are known as low-bypass turbofans, those that have considerably more fan thrust than jet thrust are known as high-bypass. Most commercial aviation jet engines in use today are high-bypass, and most modern fighter engines are low-bypass. Ver mais The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves Ver mais Low-bypass turbofan A high-specific-thrust/low-bypass-ratio turbofan normally has a multi-stage fan behind inlet guide vanes, developing a relatively high pressure ratio and, thus, yielding a high (mixed or cold) exhaust velocity.
