Abstract

The invention discloses a flight control active surface deflection angle determination method and system. The method comprises the steps of obtaining three-dimensional coordinates and mark point classification information of mark points on an active surface at the current moment; determining an activity surface type according to the mark point classification information; determining a corresponding calculation scheme according to the activity surface type; and according to the calculation scheme and the three-dimensional coordinates of the mark points, determining the deflection angle of the movable surface rotating from the reference moment to the current moment. By means of the designed mode, the rotation angle of the movable face can be determined according to the mark points on the movable faces of different types, and the method can be suitable for the special situation that the movable face is provided with a plurality of mark points, one mark point or two mark points and has good applicability.

Description

technical field [0001] The embodiments of the present application relate to the field of civil aircraft testing, and in particular, to a method and system for determining a deflection angle of a flight control active surface. Background technique [0002] During the flight of the aircraft, the attitude of the aircraft is usually controlled by the deflection of the active surfaces of the wings and tail. In order to verify whether the deflection of these active surfaces meets the requirements, it is often necessary to measure the deflection angles of these active surfaces, such as figure 1 Shown is a schematic diagram of the active surface of the aircraft. [0003] The traditional measurement methods of the deflection angle of the movable surface mainly include manual measurement, mechanical measurement and microelectromechanical systems (Microelectro Mechanical Systems, MEMS) gyro ritual measurement. Among them, the manual measurement is to measure the straight-line distance...

Problems solved by technology

However, manual measurement has the defects of poor accuracy and low measurement efficiency; the structure of mechanical measurement is complex, which may introduce installation errors, and it is necessary to read the angle value near each active surface; The measurement accuracy of the rotation angle of the heading direction is poor, and it is difficult to measure the translational data of the flaps and slats, which are both rotating and translational.
