Regulation of turbojet engine power using nozzle pressure set-point

摘要

The desired temp. of the turbine at full load (Tvsoll) is worked out and stored for various air intake rates and flight conditions. To achieve the requisite nozzle pressure set-point for full load (Ps7, soll) a time-dependent correction is applied to the temp. set-point. The correction is derived from a set of measured input and control quantities in stationary full- or part-load conditions. The corrected value is at most equal to the max. allowable turbine temp.
