    摘要： An apparatus and method for igniting a secondary pyrotechnic charge is provided, which uses hot gases produced by a first generating means to effect the secondary ignition.The hot gases from the heat generating means are directed through a heat transfer member in a second generating means, and heat from the gases is transferred to the secondary pyrotechnic charge, which is associated with the heat transfer member. Once ignited, the secondary charge provides flames and hot gases to effect the purpose of the application at hand, e.g., jet engine burner ignition.

    摘要： An emergency starter that allows responsiveness within a few seconds, without having disadvantages associated with mass and size of a back-up hydraulic or pneumatic starter. An instantaneous gas thrust of pyrotechnic type is coupled with a positive displacement transmission generator in conjunction with automatic coupling to/uncoupling from a set that is to be started. An emergency start-up system includes at least one pyrotechnic gas generator connected to an electrical initiator itself connected to a computer, a positive displacement motor housing straight-cut gears, the pyrotechnic gas generator being coupled to the motor by an inlet in the casing. The motor includes a mechanism of connection capable of moving at one end of the drive shaft configured to couple the transmission shaft to a driven shaft of the set that is to be started via a centrifugal clutch.

    摘要： A ducted fan gas turbine engine (10) is provided with an electric motor starter unit (16). The oil lubrication system of the engine (10) is so arranged that during engine starting, the heat generated by the starter unit (16) is used to heat up the oil in the system. This reduces the viscosity of the oil, thereby facilitating easy engine starting under very cold conditions.

    摘要： A fuel control system for a small gas turbine propulsion engine which enables a long term storage with fuel combined with a rapid start and operation as well as rapid stable control of the fuel flow. The control system includes an electrically controlled servo valve disposed upstream of a fuel pump, with the valve and pressure sensing cavities of a differential pressure control device being maintained full of fuel for a long term storage. Leakproof-type flexure pivots are provided for transmitting motion of an electrical torque motor to the servo valve and transmitting motion of a diaphragm to a throttle located downstream of the fuel pump. A frangible diaphragm is provided at the pump inlet which is adapted to be fractured or otherwise opened to activate the system upon a start-up of the turbine engine and, for this purpose, pressurized gas may be used to temporarily pressurize a fuel tank to burst the frangible diaphragm. The fuel flow is proportional to an applied electric current and independent of the tank or engine pressures, with the electric current being controlled by an electronic controller.
