Landing timing detecting device for unmanned aircraft
专利汇可以提供Landing timing detecting device for unmanned aircraft专利检索，专利查询，专利分析的服务。并且PURPOSE: To help control of an unmanned aircraft when it lands and improve its safety during landing phase by loading, on an unmanned aircraft, an output transmitting device which operates through a landing signal when a signal of a rotational speed sensor for detecting the rotational speed of a main wheel is inputted and the rotational speed of the main wheel increases beyond a constant value.
CONSTITUTION: Rotational speed sensors 2 are respectively provided on right and left main wheels 1 of an unmanned aircraft A, voltage signals from respective rotational speed sensors 2 are inputted into comparator circuits 3 working as two comparison devices. Further, a landing signal is output when rotational speed of the main wheels 1 reaches a constant value; and voltages of voltage signals from the revolution sensors 2 reach a predetermined value. That is, when the unmanned aircraft A lands to rotate main wheels 1, and a landing signal is outputted by the comparator circuits 3; a transponder 4 is operated through an OR circuit, the landing signal is transmitted to a ground cockpit B and is processed by a signal processing unit 6 in the ground cockpit B, and a landing timing is told to a pilot or the like by a display unit 7.
