No-tail-rotor high-speed single-wing amphibious detection helicopter

Abstract

The invention discloses a no-tail-rotor high-speed single-wing amphibious detection helicopter which comprises a single-wing power system, a vector thrust system, a shell, a hull, a frame, a solar battery, a radar, a laser detector and a power supply. The no-tail-rotor high-speed single-wing amphibious detection helicopter is mainly characterized in that two shaft thrust vector power systems are mounted at specified positions of two sides of a body, great forward thrust can be generated, yaw control moment can be generated while main rotor torque is balanced by the aid of thrust vector yaw differential motion of the two systems, pitching and rolling control moment for the body can be formed by pitching linkage and differential motion of the two shaft thrust vector power systems, the influence of unbalanced lifting force caused by speed difference between a front line and a rear line of blades in the high-speed flying process of a single-wing helicopter is overcome, the hull is matchedwith the single-wing power system and the vector thrust system, the helicopter can achieve excellent maneuvering characteristics on a water surface, a sonar device is mounted at a tail, underwater detection operation can be performed, and different positions can be timely changed.

Description

technical field [0001] The invention relates to the technical field of single-rotor helicopters, in particular to a tail-rotor-less high-speed single-rotor helicopter with solar cells and a detection function. Background technique [0002] At present, the vast majority of helicopters mostly use a single-rotor system with a tail rotor. Its disadvantages are mainly as follows: complex transmission mechanism, large power loss, too long tail boom leads to reduced flexibility, tail rotor is easily damaged and high maintenance cost. For small helicopters or small unmanned helicopters, tail rotors are less flexible, and the transmission mechanism is complex and more prone to mechanical failures, resulting in crashes. At the same time, the slow flight speed of a single-rotor helicopter with a tail rotor is a significant feature; its endurance is average, and the helicopter cannot perform the next step after the power supply is exhausted or needs to return in time.

Its disadvantages are mainly as follows: complex transmission mechanism, large power loss, too long tail boom leads to reduced flexibility, tail rotor is easily damaged and high maintenance cost, etc.

For small helicopters or small unmanned helicopters, having a tail rotor is less flexible, and the transmission mechanism is complex and more prone to mechanical failures, resulting in crashes

At the same time, the slow flight speed of a single-rotor helicopter with a tail rotor is a significant feature; the endurance is average, and the helicopter cannot perform the next step after the power supply is exhausted or needs to return in time
