Abstract

A closed loop control system is presented which trims fuel flow to the turbine engines of a multi-engine aircraft in response to fan speed and turbine temperature measurements. The closed loop system is activated after the initial climb-out phase of flight. To engage the automatic control system the pilot will first preset a not-to-exceed measured gas temperature for the turbines and secondly, adjust the throttles to bring engine fan speeds within the pull-in range of the synchronizer. This done, the pilot engages the closed loop control system which functions by having fan speed 78 and turbine temperature data 80 signals transmitted to an electronic type master control unit 82. Acting on the incoming signal data, the master control unit pulses power lever actuators 90, 92. There is a power lever actuator serially connected between each throttle lever 86, 88 and the fuel control valve associated therewith. Each power lever actuator is capable of increasing and decreasing the effective preset value of a power lever by an amount just sufficient to maintain speed synchronization and temperature control of the associated engine during the cruise phases of flight. The automatic system has limited authority and the pilot can override at any time by simply moving the throttle levers. <IMAGE>
