Then the output will decrease with altitude.

WebMay 1, 2007 · Tref is a flat rating temeperature based on the flat rated thrust used. Tmax is a maximum certified temperature for takeoff calculated accordingly to the EGT limits (max thrust reduction of 25 %) The optimization process (who gives Tflex) calculates the speeds which will produce the maximum takeoff weight or the maximum takeoff temperature for ... WebThe FADEC will be programmed to flat rate the engine at a thrust corresponding to a safe internal engine pressure. This thrust value is the rated or maximum thrust that the …
Nowadays, civil engines are usually flat-rated on net thrust up to a 'kink-point' climate. So at a given flight condition, net thrust is held approximately constant over a very wide range of ambient temperature, by increasing (HP) turbine rotor inlet temperature (RIT or SOT). However, beyond the kink-point, SOT is held constant and net thrust starts to fall for further increases in ambient temperatu… Nowadays, civil engines are usually flat-rated on net thrust up to a 'kink-point' climate.

WebJul 27, 2024 · F = (m dot * V)e – (m dot * V)0. The first term on the right hand side of this equation is usually called the gross thrust of the engine, while the second term is called the ram drag. It is a drag term because it is subtracted from the gross thrust. Since the exit mass flow rate is nearly equal to the free stream mass flow rate, and the free ...
