Abstract

768,975. Ventilating aircraft. BOEING AIRPLANE CO. May 3, 1955 [May 20, 1954], No. 12823/55. Class 137 The energy required for supplying pressure air to an aircraft cabin is derived solely from rammed air and the energy in the exhaust cabin air is utilized in assisting to drive the compressing-means. As shown, the ram inlet 10 is divided into two passages 10a, 10b. The air passing through the passage 10b. passes through a first stage compressor 12, a second stage compressor 14 and a heat exchange cooler 16, to the cabin 18. The rammed air from the passage 10a passes to a turbine 20, the exhaust from which is either dumped overboard at 24, according to the regulation of a valve 26, or is passed through the heat exchanger 16 before going overboard. The cabin exhaust duct 28 leads to a turbine 30 which is connected by a shaft 38 with the first stage compressor 12. The valve 26 is controlled automatically, according to cabin temperature, and the supply of rammed air to the second stage compressor 14 is controlled automatically by a valve 34 according to the pressure in the cabin. If required, the first and second stage compressor could be combined into one stage in which case both turbines would be coupled to the compressor. As shown the shaft 40 of the compressor-turbine set 14, 20 is rotatable on the shaft 38 of the first stage compressor, but if required two independent shafts, which could be coupled together in any gear ratio, could be provided. A single compressor could be driven by both turbines through speedchanging gears.
