Problems solved by technology

The protection device of the V750 achieves the purpose of increasing the ground contact range of the landing gear of the airframe, but the protection devices are completely independent, unable to withstand the impact of landing and bumping, and cannot protect the airframe in an emergency
The honeybee unmanned helicopter is a coaxial double-blade type, and its own flight attitude is stable. The protection device has insufficient spans in the front, rear, left, and right, and the protective effect in emergency situations is insufficient.

Abstract

The invention belongs to unmanned helicopter test trail flight guarantee equipment, and relates to a trial flight protection device special for a wheel undercarriage unmanned helicopter and used during test trial flight. According to the trial flight protection device of the wheel type unmanned helicopter, the theory of all skid landing gear trial flight protection devices of China Aviation Industrial helicopters is used for reference, the structural mode and mounting mode of a mounted connector of the trail flight protection device need to be redesigned according to the actual mounting needs of the wheel undercarriage unmanned helicopter, and the structure of a helicopter body is fully utilized for fixing the trial flight protection device.

Description

technical field [0001] The invention belongs to the field of unmanned helicopter test flight protection equipment, and relates to a special flight test protection device for unmanned helicopters with wheeled landing gear used in test flights. Background technique [0002] Unmanned helicopters are different from unmanned fixed-wing aircraft. Because of the rotor, their aerodynamic and dynamic characteristics are far more complex than those of fixed-wing aircraft. It is a modern high-tech project with multidisciplinary and multi-system integration, so it is extremely difficult technically . Unmanned helicopters need to accurately reflect the balance, compensation, decoupling and other technologies of the pilot's control of the helicopter into the flight control system. Therefore, the research on the object characteristics of unmanned helicopters is far more demanding than that of manned helicopters, and it is also necessary for autonomous flight beyond visual range. Conduct r...
