Title: Airspeed meter
Inventor: DEWEY THOMAS NORMAN
IPC: G01P5/16
Filed: 1958-11-07
Abstract: 902,284. Electrical measuring systems. SPERRY GYROSCOPE CO. Ltd. Nov. 7, 1958, No. 35838/58. Class 40 (1). An airspeed indicator for a helicopter or low speed aircraft comprises a Pitot head rotatable in a plane containing the direction in which the component of the air-speed is to be measured, a generator controlled by the output of the Pitot head to provide a cyclically varying signal representing the Pitot-static difference pressure, the output of the generator being fed to a phase detector fed also with a reference wave synchronized with the rotation so as to give an output which represents a component of the airspeed. Measurement of rectangular co-ordinates of airspeed.-Fig. 1 shows an arrangement in which a Pitot head 1 is shielded by a shroud 2 and mounted on a blade of a helicopter. A voltage dependent on the effective airspeed as the blade rotates is provided by a pressure sensitive generator 3 and is amplified by a modulator type amplifier 5, 6. The amplifier output is fed to phase detectors 11, 12 where the output is compared with the rectified output of the X and Y windings of a synchro. 14 driven by the rotor. It is shown that the outputs of the phase detectors 11, 12 when multiplied by the speed of the rotor and divided by the D.C. component of the output of the generator 3 respectively provide the forward and sideways airspeed. This is achieved by the ratiometers 24, 25 and the potentiometers 19, 21, the sliders of which move in accordance with the rotor speed. Measurement of polar co-ordinates of airspeed.- Fig. 2 shows a similar arrangement in which the A.C. component of amplifier 6 is rectified at 32 without account being taken of phase and, after multiplication by the rotor speed by means of potentiometer 33, provides a scalar value of airspeed on ratiometer 34. The output of a synchro. 36 driven by the rotor is amplified at 37 and compared with the phase of the speed voltage from amplifier 6 by means of a phase detector 35. The detector output is amplified at 38 before being fed to a servomotor 39 to drive the stator of the synchro. 36 until the output is zero. The stator is now aligned with airspeed direction. This may be indicated on a pointer 42 coupled to the stator. Stabilizing feedback is provided by a tachogenerator 41. Specification 839,405 is referred to.
