Problems solved by technology

Force measurement is mainly to measure the inertial force of tethered flying and free-flying insects and birds, but because the change of force can only be measured through the body of the animal, it brings many uncertain factors, making the distinction between inertial force and inertia produced by flapping wings force becomes very difficult

Abstract

The invention discloses a testing device and testing method for mass force of a minitype ornithopter. The testing device comprises a minitype ornithopter, a vacuum box housing, a rotary-vane-type vacuum pump, a supporting rod, a testing force mounting board, a testing force transducer, a transducer mounting board, and the like, wherein the ornithopter can flap wings in the vacuum box; the mass force obtained from acting force in the vertical direction in a state of vacuum of the ornithopter is tested through the testing force transducer. The method is conducive to testing of the accurate mass force generated during wing flapping quantitatively; variation of the force can be tested in real time under the condition that flapping frequency is given.

Description

technical field [0001] The invention belongs to the field of aerospace and relates to a device and method for testing the inertial force of a miniature flapping-wing aircraft, so as to obtain the inertial force of the aircraft when flapping. Background technique [0002] Micro flapping wing aircraft is a new concept aircraft that imitates the flight of birds or insects. Compared with fixed wings and rotors, flapping wing aircraft integrates ascent, hovering and propulsion into one flapping system, requiring only a small energy loss It can complete long-distance flight, and the fluttering and twisting of the flapping wings in a high-frequency state enables it to obtain unparalleled maneuverability. [0003] The size of insects and birds is much smaller than that of conventional aircraft, the absolute value of the inertial force generated is very small, and the flapping frequency is high, so the flow field around them presents the characteristics of small scale and rapid chan...
