Problems solved by technology

Because of this, due to the relatively backward base of the helicopter industry in our country, the lack of capital investment, and the accumulation of experience and test data, there is a considerable gap in the research and production of helicopters compared with developed countries. and civilian needs

Embodiment Construction

[0014] The invention is applicable to single-rotor helicopters, double (multi-rotor) helicopters, high-speed helicopters with thrust, 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. Other forms will not be repeated.

[0015] The main shaft (17) on the frame (16) of the tilting manipulator is arranged on the fuselage bearing beam (18) of the helicopter, and the frame (16) can tilt around the main shaft (17). And the overall rotor can be tilted in any orientation with the total axis (17) as the vertical axis and the fork-shaped shaft (15) as the horizontal axis. Engine (21) transmits power to belt pulley (14) with belt (22) so that outer shaft (5) and inner shaft (10) drive rotor (11) and the resistance plate (12) of paddle root position to rotate. The driver on the buffer ...

Abstract

The invention relates to a direct inclination control rotor helicopter and belongs to the technical field of helicopters. An inclination controller in the key technology of the direct inclination control rotor helicopter is adopted, so a blade periodic diameter changing system, a speed reducer and a tail rotor system on the traditional helicopter can be saved, and the structure of the helicopter is simplified, the difficulty in design and manufacture is lowered, the cost is reduced, the service life is prolonged, the helicopter is easy to maintain, and the vibration and the noise intensity are weakened. The direct inclination control rotor helicopter is suitable for single-rotor helicopters, dual-rotor (multi-rotor) helicopters, thrust high-speed helicopters, 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 helicopters, its design and manufacturing technology and various flight performances have been greatly improved, but the basic principles and basic structural forms of helicopter manipulation 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; the control of the flight attitude is obtained in the vibration. The helicopter's rotor system and tail rotor system are in an extremely unbalanced motion state, which is the root cause of the complex structure of the helicopter; difficult design and manufacture; high cost; low service life; complex maintenance; high vibration and noise intensity reason. The development of helicopter technology has...
