The equation governing the acceleration time of a turbojet engine is presented in an implicit form; expansion into power series contains first order partial derivatives. The derivatives represent the "sensitivity measure" of the acceleration time to the variation of a) -the design parameters of the compressor (stability margin, moment of inertial, efficiency, compression ratio), b) -technical conditions (deformation of blade profiles, due to erosion, turbine blade clearance), c) -service conditions due to flight speed and altitude. The relations derived enable the wide range simulation analysis of the problem.
