Abstract

The invention relates to a test method for a pneumatic characteristic of a wing of a combined type multi-component ornithopter, and belongs to the technical field of ornithopter performance test. A pneumatic characteristic integrated measuring platform and an ornithopter wing motion generation mechanism are included, and are connected via a flexible link rod. Force values measured by force measuring sensors in different measuring orientations are used to solve a 3D pneumatic force and a 3D pneumatic moment via certain mathematic model. A single-component cantilever beam force measuring sensorserves as the core, the test method for the pneumatic characteristic of the wing of the combined type multi-component ornithopter is provided, a force measuring device is simple in structure, low in cost of key parts and high in measurability. Multiple single-component cantilever beam force measuring sensors are combined according to certain measuring principles, the sensors are combined to improve the applicability of the test device and method effectively, a measuring scope can be expanded according to the force measuring scope of the single-component cantilever beam force measuring sensors,and measuring requiremtns of different occasions can be met.

Description

technical field [0001] The invention relates to a combined multi-component flapping-wing aircraft wing aerodynamic characteristic testing method, which belongs to the technical field of flapping-wing aircraft performance testing. Background technique [0002] The flapping wing aircraft is a new type of bionic aviation aircraft, which has the characteristics of small size, flexible maneuverability, and strong environmental adaptability. The flight power of the flapping-wing aircraft is obviously different from that of traditional aircraft. It is generated by the periodic flapping of the symmetrical wings on both sides of the fuselage and the interaction with the air. Therefore, the aerodynamic performance and flight control quality of the flapping-wing aircraft are directly related to the performance parameters of the wings. [0003] In the aerodynamic measurement of flapping-wing aircraft, the measurement accuracy of the multi-component force sensor and the coupling characte...
