Abstract
An engine thrust rating process and system for controlling engine thrust during flight of an aircraft and/or to support an airplane development program (including design, validation testing, and production of airplane systems, airplane dispatch and operation tools). The thrust rating process uses thrust ratios derived from thrust expressed in power rather than engine rotor speed (N1). In one or more examples, the thrust rating architecture is based on 'Max Rated Thrust' tables and the power setting parameter 'PSP' being calculated at the end of the process instead of at the beginning of the process (unlike conventional procedures), thereby enabling the system software development early as needed to support the airplane development phase. This concept also yields improvements such as simplified control logic, optimized engine performance and engine life.
