Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described.

[0017] Such as figure 1 Shown, the schematic diagram of rotorcraft test platform of the present invention. The rotorcraft test platform comprises a test platform support, a two-degree-of-freedom rotating support and a rotorcraft support. The two-degree-of-freedom rotating support is erected on the test platform support, and the rotorcraft support is fixed on the two-degree-of-freedom rotating support. The test platform support includes more than 3 platform legs and a frame structure erected between the above 3 or more platform legs. The frame structure includes several frames, and the frames include beam connecting parts 121 connecting the platform legs. figure 2 A preferred example of the above scheme is shown, that is, the test platform support includes 4 platform legs and a two-layer frame structure erected between the above 4 platform legs, and the frame structure is...

Abstract

The invention relates to a rotor aircraft test platform, comprising a test platform support, two free rotation supports and a rotor aircraft support seat. The test platform comprises more than three platform supporting legs and a frame body structure which is supported on the more than three supporting legs; the frame body structure comprises a plurality of frames; the frame comprises transverse beam connection members which are connected to the platform support legs; two free rotation supports comprise a PITCH rotation frame and a ROLL turn-over transverse beam; the two ends of the ROLL turn-over transverse beam are supported on the PITCH rotation framework to form hinging; the rotor aircraft support seat is fixed in the middle of the ROLL turn-over transverse beam; and the rotor aircraft is fixed on the rotor aircraft support seat. In the invention, the rotor aircraft test platform limits the rotor aircraft in the framework structure of the platform support, which enhances the safety of the test, and regulate the flight test space through regulating the size of the platform support. The rotor aircraft test platform is reliable and simple in structure, easy in assembling and transformation, and easy to observe.

Description

technical field [0001] The invention relates to a device for testing the flight state of a rotorcraft, in particular to a safe and reliable rotorcraft test platform, which belongs to the field of rotorcraft test devices. Background technique [0002] A rotorcraft is a helicopter driven by multiple propellers, especially a quadrotor. In general, most rotorcrafts are unmanned aerial vehicles, and small rotorcrafts can operate at low altitudes by remote control, and have good maneuverability and flexibility. After the prototype of the rotorcraft is produced, a series of simulation tests are usually carried out to detect various flight parameters of the aircraft. The existing simulation tests usually use the actual flight test in a selected space. This method without protective measures , when the performance of the aircraft is uncertain, it is dangerous to a certain extent, manifested as safety accidents or aircraft damage accidents, etc., and it is not conducive to the tester...
