DEVICE FOR CONTROLLING THE FUEL SUPPLY WITH PROPELLER TURBOJET ENGINES FOR AIRCRAFT BY MEANS OF A THROTTLE LEVER AND A TRIMMING LEVER

摘要

A plurality of input signals are fed to a computer which determines a "set" signal indicative of a desirable turbine gas temperature of the turbojet engine. The input signals include information as to the engine speed and the air pressure at the altitude at which the engine is operating. An "actual" signal is derived indicative of the existing turbine gas temperature and is compared with the "set" signal to produce an error signal. From the error signal indications are given to the pilot as to the movement required of the trimming lever to achieve the desirable turbine gas temperature for the conditions under which the engine is operating. The error signal can be used for automatic correction of the setting of the trimming lever.
