Abstract

The invention discloses a helicopter and ground integrated test bench rotor braking method and device and belongs to the technical field of helicopter comprehensive tests. The helicopter and ground integrated test bench rotor braking device comprises a master manipulator end arranged away from a test site, a slave manipulator end arranged on the test site, and a transmitting control system arranged between the master manipulator end and the slave manipulator end. The master manipulator end is provided with a master manipulator handle, displacement detecting equipment, a braking resistance structure controller and braking resistance structure equipment. The slave manipulator end is provided with an executing mechanism controller, an executing mechanism, a braking handle and braking resistance detecting equipment. Mechanical displacement generated by means of the method that the master manipulator handle is pulled by the master manipulator end is converted into an electric signal throughthe displacement detecting equipment, and the electric signal is transmitted to the executing mechanism controller through a transmission system to control the executing mechanism to drive the braking handle. The braking resistance detecting equipment real-timely detects braking resistance to generate an electric signal, the electric signal is transmitted to the braking resistance structure controller of the master manipulator end, the braking resistance structure equipment is controlled by the braking resistance structure controller to generate force moment, and the force moment is fed backto an operator.

Description

technical field [0001] The invention belongs to the technical field of helicopter comprehensive tests, and in particular relates to a rotor braking method and device for a helicopter ground combined test bench. Background technique [0002] The helicopter ground joint test is an important test method to verify the function, performance and durability of the three major moving parts of the helicopter rotor, transmission, and power system. The rotor brake device is one of the important components of the helicopter ground joint test bench. [0003] Helicopter ground joint test The ground joint test cycle is long. If the pilot performs the rotor brake operation, it needs to coordinate and occupy scarce helicopter pilot resources for a long time. The boring and long-lasting test will easily cause driver fatigue and increase the risk of misoperation. A compromise solution is that when the rotor brake is required, the operator performs the braking operation from the measurement and...
