Abstract
776,963. Facilitating landing of aircraft. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Aug. 8, 1955 [Aug. 11, 1954], No. 22832/55. Class 40 (1). In a device for enabling an aircraft to land vertically against a controllable vertical thrust, an indication is given or a controlling action is brought about when the speed of descent and the altitude are not in conformity with a predetermined law. As shown in Fig. 4, the position of the slider of a resistor 13 forming two arms of a bridge is controlled by the altitude and that of the slider of a resistor 14 forming the other two arms is controlled by the speed of descent. The output of the bridge, which may be shown on an indicator, is zero when the speed of descent is appropriate to the altitude. In the arrangement described, however, a second bridge is formed by the resistor 13 and a resistor 20 controlled by a motor 25 for adjusting the vertical thrust and the algebraic sum of the outputs of the two bridges is amplified and drives the motor. The altimeter described comprises a weight 7, Fig. 3, which is thrown out against the exactly equal torque of a motor 4. After the weight has reached the ground, the motor keeps the cable 5 taut and the angular position of the winding drum 1 and of a nut 9 driven by a screw on the drum shaft represents the altitude. A more usual type of altimeter may, however, be used. Rate of descent may be obtained by differentiating the voltage corresponding to the altitude.
