Problems solved by technology

[0005] The object of the present invention is to provide a kind of flight equipment lift test device, system and method, be used for solving the lift test of flight equipment, especially small and miniature bionic flapping wing aircraft, because the center of mass and the Z direction constraint that exist are not collinear, And it is not coplanar with the X-direction and Y-direction constraints, causing the center of mass to generate a turning torque applied in the X-direction and / or Y-direction, causing the problem that the lift test is inaccurate and unreliable

Abstract

The invention relates to the technical field of mechanical measurement in the aviation field, in particular to lift force testing of small and miniature bionic flapping-wing aircrafts, and discloses a flight equipment lift force testing device, system and method. The device comprises a tension measuring part which is used for measuring data which are generated by the flight equipment in a flight state and are used for representing tension; an angle measuring part which is used for measuring data used for representing a tension angle when the flight equipment is in a flight state, and the tension angle is an included angle between the direction of the tension measuring part subjected to the tension of the flight equipment and the measuring reference surface of the angle measuring part; and an attitude measurement component which is used for measuring data for representing a roll angle and / or a pitch angle of the flight equipment in a flight state. According to the device, the accuracy of lift force measurement and calculation work is ensured, and the situation that the lift force test is inaccurate and unreliable due to the fact that a rigid connection scheme cannot reflect the flight state due to over-constraint of the degree of freedom is eliminated.

Description

technical field [0001] The invention relates to the technical field of mechanical measurement in the aviation field, in particular to a flight equipment lift test device, system and method. Background technique [0002] The lift force is that the flight equipment acts on the fluid (such as: air) to overcome its own gravity and load (because it is limited to a small range of shaking in the height direction, so in this application, the air resistance in the height direction is temporarily ignored) and make it The rising force is one of the important indicators to evaluate the performance of flight equipment. [0003] The current lift measuring equipment usually constrains the flight equipment in three directions of XYZ and sets a tension test device on the Z direction) to test the force of the flight equipment in the Z direction, and then sets the measured force as described The lift of the flight equipment, and, in order to ensure that the lift measurement equipment can accu...
