Short-tail vertical-lifting gyroplane

Abstract

A short-tail helicopter helicopter, including a cockpit, a single-layer main rotor, a variable-pitch hub, a first vertical axis, an automatic swash plate, a main gearbox, an engine, a tail propeller assembly, a landing gear slide wheel, and a frame , the rotating shaft of the engine is connected with the first vertical shaft and the tail propeller assembly through the final reduction box. The invention lies in the tail propeller structural assembly installed in the rear part of the aircraft. This structural assembly can satisfy the vertical lift of the aircraft. When hovering, the tail propeller blows air to the side of the body to resist the rotation of the body; After blowing, it provides the power of the autogyro; by using this tail propeller, the advantages of the shape and function of the autogyro and the helicopter rotorcraft can be concentrated on one model, so that the aircraft has the advantages of the autogyro: short tail and safety It has the advantages of a helicopter rotorcraft: it can take off and land vertically, pan, hover, and fly in any direction without sliding.

Description

technical field [0001] The invention belongs to a rotorcraft of an aircraft, in particular to a short-tail helicopter rotorcraft. Background technique [0002] Existing gyroplanes can be divided into helicopter gyroplanes and autogyroplanes. Helicopter rotorcraft generates lift by the rotation of the upper main rotor, blows air to one side from the tail propeller, resists the body rotation caused by the forward movement of the main rotor, and controls the turning direction of the aircraft by controlling the resistance. The main rotor and tail propeller All driven by the engine. Autogyro is a rotorcraft that utilizes the relative airflow during forward flight to blow the upper main rotor to rotate to generate lift. The upper main rotor is not connected to the engine. The power of the forward flight of the autogyro comes from the backward blowing propeller at the tail, and the tail propeller is connected with the engine. From the appearance, in order to meet the load, the d...

AI Technical Summary

Problems solved by technology

To sum up, the advantages of helicopter rotorcraft: it can lift vertically, hover, and fly in any direction; but it has a long tail, especially in the actual use of light helicopters, dragging a long tail increases the volume and Unsafe factors, still can not give full play to the safety of the autogyro

Although the autogyro has a short tail and has unique safety features, it is not as flexible as a helicopter gyroplane, and it needs to glide for a certain distance when it takes off and lands.
