The invention provides a four-degree-of-freedom aircraft parameter adjusting platform and a working method thereof. The platform comprises a main frame in modular design, a spherical hinge rotating shaft, a central plate, a central spherical hinge column and a mounting bottom plate, wherein a plurality of second spherical hinge shells are arranged on the periphery of the central plate, the centralspherical hinge column is fixed to the central plate, and the top end of the central spherical hinge column is connected with the mounting top plate; the main frame comprises a plurality of supports,the spherical hinge rotating shaft comprises a plurality of rod shafts, and the two ends of each rod shaft are connected with the supports of the main frame and the central plate respectively. The platformhas multiple degrees of freedom, can simulate the yawing-pitching-rolling attitude of the aircraft more truly, can perform experimental parameter adjustment and flight on various rotor aircrafts, is simple in structure, can be disassembled and assembled quickly, is simple to use, is suitable for preliminary parameter adjustment of the aircraft, and has a wide application prospect.
Description
technical field [0001] The invention relates to the technical field of aviation equipment, in particular to a four-degree-of-freedom aircraft parameter adjustment platform and a working method thereof. Background technique [0002] Various types of aircraft have become very popular in recent years and are widely loved by children and young men and women. In particular, rotorcraft has not only been used in the field of photography, but also widely used in publicity, performance and entertainment due to its stable hovering performance in the air. However, as a complex mechanical device, the aircraft has certain dangers. In order to improve its safety, the aircraft should be adjusted and experimentally flown to verify whether its flight status is in line with expectations. This process is of great help to model aircraft enthusiasts and researchers. [0003] Most of the test equipments on the market are bulky, inconvenient to carry, expensive, too professional, and have a wide...
