Helicopter screw propeller operating device

Abstract

This invention is a helicopter screw propeller control device, it includes two long and short aerovanes corresponding set, and control equipment made up by connecting-rod is connected to the two aerovanes. Control cover with versatile pendular ability is connected to bottom part of the control device, the bottom part is connected to servo universal control mechanism of helicopter through bearing, the part said is rotated with screw propeller. The two aerovanes are set on the same plane, two arc out web frames are corresponding set together, their ends together are connected to a set of aerovanes, inner connecting frame is set in hollow of the central part, another group of aerovanes are set on the inner frame, the aerovanes on the inner frame extended out of the out connecting frame. Air dynamic performance of the helicopter is greatly improved, and the helicopter's dynamic efficiency is greatly advanced.

Description

【Technical field】 [0001] The invention belongs to a rotary wing pitch control mechanism of a model helicopter. The rotary wing pitch control mechanism of the model helicopter includes functions for improving the flight stability and improving the Aerodynamic performance and efficiency of the rotor. 【Background technique】 [0002] In the helicopters in the existing model airplanes, the pitch of the rotor is adjusted by using the pull rod and the control sleeve with the ability to swing, and the flight state of the helicopter can be changed by adjusting the pitch, so as to realize the lifting and the left and right forward and backward movements of the helicopter. Most model helicopters have four rotors, two long rotors and two short rotors. The long rotors are mainly used for the lifting and hovering of the helicopter. Movement, the above-mentioned long rotor and short rotor are set correspondingly. In the existing technology, the long rotor and the short rotor are connecte...

AI Technical Summary

Problems solved by technology

In the existing technology, the long rotor and the short rotor are connected to the main shaft with a certain distance apart. Simply speaking, the above-mentioned long rotor and short rotor are not on the same plane when rotating. According to the principle of aerodynamics, When the above-mentioned two sets of rotors rotate, the airflows generated interfere with each other, affecting the performance of the helicopter. At the same time, the above-mentioned interfering airflows also reduce the utilization efficiency of the engine

The above phenomenon has a very obvious impact on model aircraft with low power. Although this problem has existed for a long time, it cannot be effectively solved.
