Problems solved by technology

[0003] The technical problem solved by the present invention is: a mechanical device called "tilt manipulator" has been designed, which can keep the angular velocity between the power input shaft and the rotor rotation axis when the rotor is directly tilted in any direction, The force and force are constant, so a uniformly rotating overall rotor system can be used to replace the traditional helicopter's extremely unbalanced blade cycle pitch system, reducer and tail rotor system in mechanical operation

Embodiment Construction

[0020] The invention is applicable to single (multiple) rotor helicopters, coaxial twin-screw helicopters, high-speed helicopters with thrust, helicopter-rotor aircraft, unmanned aerial vehicles and other related aircraft and mechanical devices. Here we only take a single-person helicopter as an example to illustrate the relationship between the tilt manipulator and the structural arrangement of the whole machine system, and the other forms will not be repeated.

[0021] The main shaft (17) on the tilting manipulator frame (16) is arranged on the bearing beam (18) of the helicopter fuselage, and the driver's driving joystick (24) on the buffer seat (23) drives the left and right two pull rods (25) Make the cantilever (20) move up and down in the same direction and in the opposite direction so that the rotor can be directly tilted. Manipulating the pedal (27) can make the push rod (13) move up and down by the pull bar (28) to change the size of the windward area of ​​the resist...

Abstract

The invention relates to a direct inclination control rotor helicopter and belongs to the technical field of helicopters. A rotor inclination controller as the key technology of the invention is a transmission system mutually hinged by a rotor shaft on the helicopter, two pairs of bevel gears mutually and vertically engaged on a horizontal axis and a vertical axis, can direct operate the inclination of the helicopter rotor, and save a blade periodic diameter changing system, a speed reducer and a tail rotor system on the traditional helicopter, thus the structure of the helicopter is simplified, the difficulty in design and manufacture is lowered, the cost is reduced, the security, the reliability and the service life is prolonged, the helicopter is easy to operate and maintain, and the vibration and the noise intensity are weakened. The direct inclination control rotor helicopter is suitable for single(multiple)-rotor helicopters, coaxial dual-propeller helicopters, thrust high-speed helicopters, helicopter-rotors, unmanned planes and related aircrafts and mechanical devices in other forms.

Description

Technical field: [0001] The invention belongs to the technical field of helicopters. Background technique: [0002] In the history of nearly one hundred years since the invention of the helicopter, its design and manufacturing technology and various flight performances have been greatly improved, but the basic principles and basic structural forms of the helicopter have not changed much. As a mechanical device, the helicopter has an artificial vibration system that plays an aerodynamic role. It can be said that the helicopter obtains the balance of flight in the vibration, and obtains the control of the flight attitude in the vibration. The helicopter's rotor system and tail rotor system are in an extremely unbalanced motion state, which causes the helicopter to have a complex structure; design and manufacture are difficult; cost is high; safety, reliability, and service life are low; manipulation and maintenance are complicated; Root cause of high vibration and noise inten...
