The system comprises a power output mechanism, a main rotor wing load simulation mechanism, a main reduction output shaft loading unit, a tail shaft loading compensation mechanism, a tail reduction output shaft loading unit and a data acquisition and processing unit which are connected with a control unit, wherein the power output mechanism is used for providing simulated input drive for an unmanned helicopter transmission mechanism, the main rotor wing load simulation mechanism is used for simulating the main rotor wing torque of an unmanned helicopter, the main reduction output shaft loading unit is used for simulating lift force, lateral force and bending moment in actual flight, the tail reduction output shaft loading unit is used for simulating tail shaft thrust in actual flight, and a tail rotor wing load simulation mechanism is used for simulating tail rotor wing torque in actual flight. According to the invention, torque applied by the engine and the main tail rotor blade can be applied, lift force and bending moment from the main tail rotor wing system can also be applied, and almost all actual loads applied to the transmission mechanism in flight are simulated.
Description
technical field [0001] The invention relates to an unmanned helicopter transmission test system and method, in particular to an electric feedback type unmanned helicopter transmission test system and method with multi-channel coordinated loading, belonging to the field of unmanned helicopter manufacturing. Background technique [0002] The transmission system of an unmanned helicopter is one of its three major moving parts. It bears the complex static load and fatigue load brought by the rotor, tail rotor, control system and engine system. force conditions. Fatigue of transmission system components directly threatens the flight safety of unmanned helicopters. Regardless of military specifications or civil airworthiness specifications, it is required that the transmission system has an extremely low probability of fatigue damage during the life cycle of the helicopter. In order to avoid catastrophic consequences due to fatigue, it is necessary to conduct fatigue tests on th...
