Unmanned Helicopter Performance Testing Platform

Abstract

The invention relates to an unmanned helicopter performance testing platform, belongs to the field of aerospace technologies and aims at solving the problems that the fixing structure is unstable, the balance performance in the movement process is poor and a testing table is damaged in the prior art. The unmanned helicopter performance testing platform comprises a platform body assembly and a flight simulator, wherein an unmanned helicopter is fixedly arranged on an upper platform of a six-degree-of-freedom moving platform, and lifting force data generated during the flight of the unmanned helicopter is transmitted to a computer through a lifting force sensor A which is fixedly arranged on the lower surface of a lower platform of the six-degree-of-freedom moving platform and a lifting force sensor B which is fixedly arranged on the lower surface of an iron plate module, so as to realize performance testing. The unmanned helicopter performance testing platform has the beneficial effects that the action of the unmanned helicopter is provided by virtue of the six-degree-of-freedom moving platform and a positioning sleeve can prevent the helicopter from flying away from the testing table when the flight control of the helicopter fails or an experiment fails; since the lower surface of the lower platform of the six-degree-of-freedom moving platform is seated on the upper surface of a shock absorbing plate, the balance of the unmanned helicopter is kept; the shock absorbing plate, a large compression spring and a small compression spring also play a certain role in buffering.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and relates to a test platform in the aviation field, in particular to an unmanned helicopter performance testing platform. Background technique [0002] The unmanned helicopter control system is controlled according to the instructions of the flight control computer on the helicopter, including the rotor control mechanism, the heading control mechanism and the throttle control mechanism. Its structure is relatively simple, and its flying flexibility is quite high. Compared with manned helicopters, it has the advantages of no casualties, small size / light weight, low cost of manufacture and use, high battlefield survivability, and wide range of military and civilian applications. Compared with unmanned fixed-wing aircraft, unmanned helicopters have the characteristics of small landing site, vertical take-off and landing, hovering in the air, long-term flight at ultra-low altitude (below 150 met...
