Landing automatic flameout system for unmanned helicopter

Abstract

The invention provides a landing automatic flameout system for an unmanned helicopter, belonging to the technical field of the unmanned plane. The system is characterized by comprising a contact switch, a safety switch, an insulating strip and a weight, wherein the contact switch and the safety switch are connected in series with a flameout wire of an engine of the unmanned helicopter; the contact switch is used for detecting a landing state of the unmanned helicopter; the safety switch is used for ensuring that the system just starts to work after the unmanned helicopter takes off; and when the unmanned helicopter lands, the contact switch is closed due to pressure, the engine automatically flames out instantly because of short circuit of a flameout circuit. The landing automatic flameout system simultaneously considers the problems of engine ground start and landing automatic flameout of the unmanned helicopter, and can realize automatic flameout of the unmanned helicopter safely, simply and reliably.

Description

Unmanned helicopter landing automatic flameout system technical field The invention is an automatic flame-out device for unmanned helicopter landing, which can safely and reliably extinguish the engine when the helicopter is landing. It is mainly used in technical fields such as aerospace, drones and robots. Background technique The engine of an unmanned helicopter is the source of power for flight. While it has energy, it is also potentially dangerous. After the unmanned helicopter lands, the engine should be turned off as soon as possible to avoid possible accidents. In the past, there were mainly two types of engine flameouts for unmanned helicopters, manual flameout and automatic flameout. The way of artificial flameout is that the operator controls the engine flameout through the remote control. The manual flameout method requires the operator to pay close attention to the landing of the helicopter and reduce the degree of automation of the unmanned helicopter tha...

AI Technical Summary

Problems solved by technology

However, due to the high-voltage electromagnetic signal contained in the engine flameout line

If the flight control computer directly controls the flameout line, it may introduce an electromagnetic pulse from the engine and cause the flight control computer to fail due to severe disturbance

In addition, since this method is software-hardware coordinated control, the probability of failure is high

If there is a misfire during the flight of the unmanned helicopter, the unmanned helicopter will quickly crash due to loss of power
