    • Aero gas turbine engine equipped with an afterburner and a final nozzle having a variable discharge area in which a direct mechanical or electrical connection exists between the nozzle actuating mechanism and the afterburner fuel control unit for controlling the degree of after-burning as a function of the actual nozzle discharge area during transient engine operating conditions with the engine throttle moving in the after-burning range above a predetermined speed. A working line trim unit of limited authority is provided for making minor adjustments to the nozzle discharge area during steady state operation, while the degree of afterburning signal from the nozzle to the fuel control unit is held constant. This working line trim unit is locked out of the control cycle during transient operating conditions so as to assure the direct control of the degree of afterburning as a function of the actual discharge area during these transient conditions.

    • A control system for a gas turbine engine having an augmenter combustion system and a variable area exhaust nozzle. The control system is applicable to both turbofan and to straight turbojet engines. In the turbofan application, a signal generator schedules the exhaust nozzle area as a function of throttle position and augmenter fuel flow as a function of exhaust nozzle area. An error signal generated between desired fan duct mach number and actual fan duct mach number is integrated and applied to both the augmenter fuel rate generator and the exhaust nozzle area generator. In this manner, during steady state operations, the exhaust nozzle position maintains a desired mach number and the throttle lever position maintains augmenter fuel flow rates. During transients, the exhaust nozzle area position controls the augmenter fuel flow. In the turbojet application the fan duct mach number error signal is replaced by a turbine temperature error signal and the system operates essentially as described above.
    • 一种用于具有增压器燃烧系统和可变面积排气喷嘴的燃气涡轮发动机的控制系统。 控制系统适用于涡轮风扇和直喷涡轮喷气发动机。 在涡轮风扇应用中,信号发生器作为排气喷嘴区域的函数调节作为节气门位置和增压器燃料流量的函数的排气喷嘴区域。 在所需的风扇管道马赫数和实际的风扇管道马赫数之间产生的误差信号被集成并应用于增压器燃料发生器和排气喷嘴区域发生器。 以这种方式,在稳态操作期间,排气喷嘴位置保持期望的马赫数,并且节流杆位置保持增加的燃料流量。 在瞬变期间,排气喷嘴区域位置控制增压器燃料流量。 在涡轮喷射应用中,风扇管道马赫数误差信号由涡轮机温度误差信号代替,并且系统基本上如上所述地操作。
