Title: Compressor bleed air flow control
IPC: F04D27/02
Filed: 1969-06-26
Abstract: 1,244,892. Axial-flow compressors. UNITED AIRCRAFT CORP. June 26, 1969 [Aug.12, 1968], No.32263/69. Headings F1C. Apparatus for controlling the bleed of air from a multi-stage compressor having a first bleed 8 and a second bleed 10 at a late stage of the compressor includes means for switching from the first bleed to the second bleed, comprising a duct 12 connecting the bleed 8 to the bleed outlet duct 14 and containing a check valve 18 to prevent back flow from the outlet duct 14 towards the bleed 8, a duct 16 connecting the bleed 10 to the outlet duct 14 and containing a normally-closed valve 20, pressure-sensing means 22 sensing a pressure which is unaffected by the opening of the valve 20 and which is a function of the pressure at the bleed 8, and means for opening the valve 20 in response to the sensed pressure indicating a pressure at the bleed 8 below a predetermined limit. The pressure sensed by the means 22 may either be the pressure at the bleed 8 or (as shown) the pressure at the bleed 10 (since the latter pressure, while higher than the pressure at the bleed 8, bears a functional relationship to it). When the sensed pressure falls below a predetermined value, a valve 30 which is normally held down by a diaphragm subjected to the pressure at the bleed 10 moves upwards to the position shown, in which it closes a vent and opens communication with the bleed 10, whereby the pressure P s  rises and operates a half-area actuator 28 to open the bleed valve 20. Compensation for altitude variation may be afforded by an evacuated bellows 34. The bleed pressure downstream of the valve 20 may be regulated by varying the pressure P so as to vary the opening of the valve 20. For this purpose, a bleed valve 36 downstream of a restrictor is controlled by diaphragms 38, 40 subjected to the pressure at the bleed 10. In addition, a pressure regulator 24 may be provided.
