Embodiment Construction

[0013] Referring to Figure 1, the test platform for testing the flight performance of a small unmanned helicopter mainly includes a frame, a universal rotating mechanism and a counterweight mechanism. The frame includes a columnar bracket composed of an upper base 13, a lower base 20 and a pole 17. And the platform 7, the upper base has an axial through hole 9, the platform has a central hole 8, the lower surface of the platform is fixed with a positioning cylinder 15 coaxial with the central hole 8, the positioning cylinder 15 is placed on the axis of the upper base Into the through hole 9 and fixed with the upper base 13. In the specific example shown in the figure, the cylindrical bracket is a triangular bracket, and the upper base 13 is shown in Figures 3 and 4, which is a cylindrical body with a through hole in the axial direction, and a regular triangular prism with a fixed bracket rod 17 is arranged in the middle of the cylindrical body. 18. A threaded hole 14 is provided i...

Abstract

The invention discloses a test board for testing small type pilotless gyroplane flight performance, which mainly comprises a frame, an all-around steering mechanism and a balanced weight mechanism, wherein the pilotless gyroplane is fixed on the plate of the test board; when the pilotless gyroplane with all-around steering mechanism and arm brace gets off, it uses the top end of the arm brace as the center of the ball to do a limited spherical movement to achieve leaning, crabbing and rotating and so on.

Description

Technical field [0001] The invention relates to a test platform for testing the flight performance of a small unmanned helicopter. Background technique [0002] Small unmanned helicopter (hereinafter referred to as unmanned helicopter) refers to a vertical take-off and landing (VTOL) unmanned aircraft that is operated by radio ground remote control or autonomously controlled flight. It is a rotary-wing aircraft in structure and a vertical take-off and landing in function. Aircraft. In the past ten years, with the development of technology such as composite materials, power systems, sensors, and especially flight control, unmanned helicopters have developed rapidly and are increasingly becoming the focus of attention. Unmanned helicopters have unique flight performance and use value. Compared with manned helicopters, unmanned helicopters have incomparable superiority in many aspects due to the characteristics of no casualties, small size, low cost, and strong battlefield survivabi...
