Abstract

The invention discloses a hydraulic control system for a helicopter ground integrated test bench, and belongs to the technical field of helicopter tests. The system comprises an upper computer, an analog quantity I / O module and a steering engine controller; the upper computer is used for inputting an instruction and has a display processing function, the analog quantity I / O module is used for performing digital-to-analogue conversion, and the steering engine controller is used for receiving data transmitted by the analog quantity I / O module and controlling a main steering engine and a tail steering engine. The hydraulic control system for the helicopter ground integrated test bench further comprises a hydraulic system, a hydraulic pump in the hydraulic system serves as an accessory of a main speed reducer, an output shaft of the accessory of the main speed reducer is driven by an engine, the hydraulic pump is connected with the main steering engine and the tail steering engine through valves and pipelines, and the main steering engine, the tail steering engine and the hydraulic system all adopt airborne parts. According to the hydraulic control system for the helicopter ground integrated test bench, the real working condition of the helicopter hydraulic control system can be better simulated, the helicopter hydraulic control system can be better assessed, and meanwhile it is guaranteed that data of other test projects are truer and more effective.

Description

technical field [0001] The invention belongs to the technical field of helicopter testing, and in particular relates to a hydraulic control system of a helicopter ground combined testing platform. Background technique [0002] As the power and actuator for helicopters to change collective pitch, cyclic pitch, and tail rotor pitch, the hydraulic control system's functions and performance are extremely important for helicopter flight and ground tests. [0003] For helicopters using fly-by-wire flight control, the hydraulic control system related to the flight attitude includes hydraulic oil tanks, hydraulic pumps, valves and hydraulic pipelines, steering rods, flight control computers and main and tail rotor servos. Driven by the engine and the main reducer, the hydraulic pump provides a high-pressure oil source for the action of the steering gear. The driver manipulates the collective distance lever, the steering column and the pedals, and the mechanical signal is converted i...
