    摘要: A fuel control system for a gas turbine aero engine comprises a first metering valve 22 which is controlled by a feed back loop 43 in flow series with a manually operated metering valve 34. A pressure drop regulator 31, 39 regulates the pressure drop across the series connected valves 22, 34. In this way response of the control system is directly influenced by movement of the manual valve 34 and the automatic valve 22 stabilizes the fuel flow rate in response to monitored operating parameters of the engine.

    摘要: Fuel for the combustion equipment of the engine of a vertical take off aircraft is supplied via pumps 50,24 through a metering valve 22, which is under the control of a digital electronic control unit (DECU) 10. A pressure drop regulator 30 and spill valve 32 ensure there is a constant pressure drop across the metering valve 22. To provide a rapid reduction in fuel output when the aircraft pilot slams shut his control lever 16 when he touches down after a vertical landing, and therefore prevent the aircraft from bouncing, the DECU 10 detects the sudden slamming closed of the lever 16, and opens a solenoid valve 60. Fuel now bleeds along line 58, and the input 54 of the regulator 30 sees an increased pressure drop determined by a potentiometer formed by two flow restricting orifices 56,62. The regulator 30 therefore opens the spill valve 32 giving the desired rapid reduction in fuel flow through the metering valve 22.
