WebHigh Bypass-Ratio Turbofan Engine. In the 1970s high bypass ratio turbofan engines were ... and the fuel consumption. For a turbojet engine the specific fuel consumption (sfc) is defined as the rate of consuming fuel mass divided by the thrust. The units will be of the form grams/second/newton (g s −1 N −1) or pounds/hour/pound (lb h −1 ... WebThrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific.This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit fuel consumed.

Bypass ratio. Schematic turbofan engines. The high-bypass engine (top) has a large fan that routes much air around the turbine; the low-bypass engine (middle) has a smaller fan routing more air into the turbine; the turbojet (bottom) has zero bypass, and all air goes through the turbine. The bypass ratio ( BPR) of a … Ver mais The 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. A 10:1 bypass ratio, for example, means that 10 kg of air passes through the … Ver mais In a zero-bypass (turbojet) engine the high temperature and high pressure exhaust gas is accelerated by expansion through a propelling nozzle and produces all the thrust.
