Abstract

1,037,324. Gas turbine engine fuel systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 13, 1963 [May 21, 1962], No. 19516/ 62. Heading F1G. In a protective control system for gas turbine engines utilizing an air/fuel ratio trip valve, the air flow signal for operating the valve in opposition to the fuel flow signal is derived from the difference in pressure between the total head in the ducting through which air passes to the compressor and the static head in the inlet annulus to the compressor blading. In the engine shown air is supplied through the ducting 2 to the inlet annulus 3 of the compressor 1 and the static pressures in the ducting 2 and inlet annulus 3 are measured by tappings 7b, 8b, the pressures being communicated through lines 7a, 8a to the compartments 7, 8 at either side of the diaphragm 6. Fuel is supplied to the engine through an air/fuel ratio trip valve 5, fuel being supplied thereto through inlet 5a and discharging therefrom through outlet 5b. The valve member is connected to the diaphragm 6 by means of a rod 6a. The valve 5 is thus subject to a signal of fuel flow derived from the fuel pressure drop and to a signal of air flow in the engine. The velocity of the air flow in the ducting 2 is assumed to be negligible so that the static pressure signal measured by the tapping 7b is substantially a measure of the total head in the ducting.
