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.

De-rated climb thrust is a feature used to reduce climb thrust in the third, fourth and enroute climb segments. It uses more fuel in climb to altitude, but the engine operates at less EGT's therefore prolonging engine life. Fuel is cheaper than overhaul costs. tms022 2xtl-d36w

Thrust Equation - Glenn Research Center NASA

WebThe flat rating of a turbine engine is the thrust performance that is guaranteed by the manufacturer for a new engine under specific operating conditions, such as takeoff, maximum continuous climb, and cruise power settings. The turbine inlet temperature is proportional to the energy available to turn the turbine. Web1) Thrust lapse rate, the rate at which engine net thrust decays with flight speed, is also a function of bypass ratio, and engines which are sized specifically for cruise thrust-drag matching will certainly produce increases in take-off thrust with ….
