Title: Means for preventing the formation of ice on an aircraft or in a gas turbine engine therefor
Inventor: LINDSEY WILLIAM HENRY
IPC: B64D15/16
Filed: 1950-04-29
Abstract: 676,154. De-icing aircraft. ARMSTRONG SIDDELEY MOTORS, Ltd. Feb. 12, 1951 [April 29, 1950], No. 10608/50. Class 4. [Also in Group XXVI] In an aircraft having at least two ice detectors arranged to respond to different degrees of icing each detector operates a control unit supplying during response of the detector a predetermined quantity of anti-icing fluid to the part of the aircraft on which the formation of ice is to be prevented. The arrangement is such that the quantity of de-icing fluid supplied at any moment depends upon the icing conditions then obtaining. The invention is described with reference to a gas turbine shown in Fig. 1 which has an intake passage 11 formed between an inner fairing 12 and an annular casing 13. The forward end of the fairing 12 is formed by a spinner 15 carrying vanes 19 by means of which it is rotated. Forwardly-facing spray nozzles 25 for the de-icing fluid are mounted on the ends of the blades 19. A further spray nozzle 29 is mounted at the forward end of the spinner 15. A multi-cylinder pressure pump 34 for the anti-icing fluid, driven by an electric motor 35, has one cylinder feeding the spray nozzle 29 through the pipe line 30 and the remaining cylinders feeding the manifold 36 which supplies the pipe line 28 connected to the spray nozzles 25. One ice detector 39 is mounted externally of the intake and a second detector 40 mounted internally of the intake downstream of the spraying devices 25 and 29. The arrangement is such that under mild icing conditions the detector 39 operates and under more severe conditions, the detector 40 also operates. The detector 39 is connected by a pipe line 47 to a known form of control unit 49 which energises the motor 35 through a rheostat 50 to operate the motor at an appropriate speed. The second detector 40 is connected by a pipeline 52 with a control unit 53, similar to the unit 49, which through a rheostat 54 increases the speed of the motor. To prevent waste of de-icing fluid when icing conditions have ceased due to the time lag before the detector is free from ice, at least the first-responding 'detector should be provided with a known form of thermal de-icing means 42, which is periodically operated. To maintain the supply of de-icing fluid under icing conditions, the control unit 49 is arranged so that the fluid is not cut off for a period which is at least as great as each of the periods between the operation of the thermal de-icing means. The spinner 15 may form part of the spinner of an airscrew. In a modification, both of the detectors are mounted so as to be subject to the same icing conditions, but are made to respond differently by varying the size of the holes in the leading edge of the detector as shown at 44, 45, Fig. 3, or by placing one of the detectors in a choke tube. The invention may be applied to the de-icing of the propeller, wings and control surfaces of an aircraft.
