Abstract

1316275 Ventilating aircraft BRITISH AIRCRAFT CORP Ltd 23 Dec 1970 [2 Oct 1969] 48491/69 Heading F4V [Also in Division F1] The invention relates to a power supply system for essential services of an aircraft, the aircraft having a cabin 7 which is pressurized from a source of air under pressure under the control of a pressurization and air conditioning system. Air under pressure is supplied from a source such as a tapping from a compressor of a gas turbine propulsion engine through line 1 and passes through control valve 2 to a first air cooler 3 then through a second air cooler 6 and water separator 8 to the cabin 7. The power supply system comprises two air turbines 16a, 16b which are connected through gearing 16c to drive an electric generator 17. The air turbine 16a is supplied with air under pressure from lines 1 and 18 under control of valve 19, the valve being controlled in dependence on temperature in the cabin as sensed by device 22, and the air turbine 16b is supplied either with air discharged from the cabin through lines 14a, 20 or with air under pressure from lines 1 and 1d in dependence on the position of the changeover valve 21. A by-pass 1a is provided across the air cooler 3, being controlled by a valve 4 in dependence on temperature in the cabin. The air cooler 6 is also provided with a by-pass 1b controlled by a valve 9 also in dependence on temperature in the cabin. The air cooler 6 comprises an air compressor 6a driven by an air turbine 6b, air from the compressor being cooled in a heat exchanger before passing to the turbine. The heat exchanger also the air cooler 3 are cooled by flow of ram air through duct 10. A fan 11 driven by a tip turbine is provided to supply a flow of cooling air to the duct 10 when the aircraft is on the ground. Means 23 are provided to supply warm air to the exhaust outlet of the air turbine 6b to prevent freezing. Similarly, means 24 are provided for preventing freezing at the exhaust outlet of the air turbine 16a. The air discharge from the cabin 7 is through a first valve 13 and a second valve 15.
