A given method and given device for aircraft angle of attack

Abstract

The invention relates to a giving method and a giving device of an aircraft incidence angle. Based on an incidence angle weather cock which has been installed on an aircraft body already, the giving device comprises a base, a dial and a weather cock pointer; an outer ring of the base is connected with a sucker type stabilizer blade through an adjusting bolt, and a pressing block of the dial is further arranged on the surface of the annular base; the dial is an annular disc, aircraft incidence scale marks are arranged on the surface of the dial, and the dial is arranged on an annular step of an inner ring of the base and is concentric with the base; a connecting hole sleeved with the incidence angle weather cock is arranged at the tail end of the weather cock pointer; an opening ring in the center of the base is arranged on peripheral aircraft body skin of an incidence angle weather cock shaft, and the base is adjusted to be in the relatively horizontal state; the front end of the weather cock pointer points to the 0-degree scale mark of the dial; and a manual weather cock enables the weather cock pointer to point to the needed aircraft incidence angle direction.

Description

technical field [0001] The application relates to aircraft manufacturing technology, in particular to a given method and given device for an aircraft angle of attack in the detection and debugging of an aircraft stall warning system. Background technique [0002] The aircraft's stall warning system is to send warning and control information to the pilot and the flight control system when the aircraft is approaching a stall. The purpose is to provide a sufficient range between the stall warning and the actual stall, and to enable the pilot or the flight control system to control The aircraft is an important airborne equipment that allows the aircraft to quickly return to a normal state without causing the aircraft to enter a stall state, thereby ensuring flight safety. It is of great significance for the pilot to correctly control the aircraft and ensure flight safety. Since the alarm point and alarm function of the aircraft stall warning system are closely related to the rea...
