Abstract: 596,608. Indicating. GLENNY, A. P., and SPERRY GYROSCOPE CO., Ltd. June 15, 1945, No. 15197. [Class 106 (iv)] [Also in Groups XX and XXXVIII] The airspeed and its direction relative to a fixed axis, e.g., the longitudinal axis of an aircraft, are both indicated on a single-pointer instrument. As shown diagrammatically, Fig. 1, a pitot-head 6 combined with a wind-vane 2, is rotatably mounted about an axis 5 in the fuselage 4, so that the airspeed produces through the pitot-head, double diaphragm arrangement 13 and levers 27, 28, a corresponding angular movement of arm 25 about pivot 26, and a selsyn transmitter 38 is position in correspondence with the direction of the airflow relative to the fore-aft axis of the aircraft by the vane 2. The arm 25 through a potentiometer 29 and coil 30 deflects a pointer 33 about its pivot 34 in accordance with air-speed while the pointer together with its mounting is rotated about the axis 36 by the selsyn or other receiver 37 through gearing. In a practical embodiment, the receiver 37, Fig. 2, rotates through gearing 56 a member 40 carrying a bracket 41 to which the electromagnet 30 is secured and a further bracket 35 in which the spring biassed pointer 33 is rotatably mounted. The coil 30 is fed through slip rings 48. The spherical dial 57 may be transparent but preferably the pointer is luminous or otherwise arranged to project a light-spot on to a translucent dial. The dial is graduated with circles or arcs concentric with the origin 36, Fig. 3 (not shown) corresponding to various speeds the radial distance and direction of the indicator 33 giving the airspeed and direction thereof. In a modification, Fig. 4 (not shown), the combined pitot-head and wind vane of Fig. 1 are replaced by two divergent pitotheads arranged symmetrically with the fore- and-aft axis of the aircraft. The pressures derived from the two pitot heads are fed to a double diaphragm arrangement which through lever systems sums the two pressures to operate the potentiometer arm 25 according to airspeed, and rotates the Selsyn transmitter 38 in accordance with the pressure difference which is a measure of the airspeed direction. The electrical repeating arrangements may be dispensed with in this embodiment the lever system operating the indicator directly.
