摘要

A process for the calculation of the fuel consumption of aircraft using the so-called belonging to the engine drive work deck, a matrix, which the fuel mass flow in dependence on external conditions, such as thrust, flight altitude, flight - mach number, and ambient temperature for a defined secondary power removal, namely a certain shaft power output and a specific bled air amount per unit of time, characterized in that for each engine of an aircraft for the purpose of calculation of the fuel consumption of the aircraft components of an aircraft a plurality of driving work deck for each assumed power as a function of external specifications are produced, and a drive mechanism of a work deck for the state without secondary power removal, in each case a drive mechanism of a deck for power tool on the individual engine shaft and a respective drive work deck for the tapping of bleed air at different points of the compressor of the engine, and specifically in the case of a relative enthalpy of the tap of in each case 0 and 1, and in that the fuel consumption of the individual drive individually loaded in the factory models for the current system power demand, with the following equation is calculated where b is_s the specific fuel consumption, b_{s, 0} the specific fuel consumption without..
