Safety protection system of aircraft with multiple rotor wings

Abstract

A safety protection system of an aircraft with multiple rotor wings comprises a receiver used for receiving ground remote control signals, an aircraft control circuit, a speed reducer, motors which are fixed at the ends of all rotary arms (1), and an aircraft power supply used for providing power for all above devices. The safety protection system of the aircraft with the multiple rotary wings is characterized in that a protection device control circuit, and a plurality of parachute popping-out devices (3) which are connected with the protection device control circuit and is controlled by the protection device control circuit to be triggered are arranged, after the parachute popping-out devices (3) are triggered, parachutes in the parachute popping-out devices are popped out, and protection to the multiple rotor wings is achieved. According to the safety protection system of the aircraft with the multiple rotor wings, the aircraft with the multiple rotor wings, which is in the flight process or in the low-altitude flight process, can be quickly and reliably protected, falling of the aircraft with the multiple rotor wings is prevented, and loss and personal injuries are avoided.

Description

technical field [0001] The invention relates to a multi-rotor aircraft safety protection system, which belongs to the field of multi-rotor aircraft safety equipment. Background technique [0002] Multi-rotor aircraft is a common unmanned aerial device. Due to its small size, reliable performance and high flexibility, it is widely used in various fields and can perform various flight tasks (such as aerial photography). When the multi-rotor aircraft is flying, especially at low altitude, once the multi-rotor aircraft breaks down, such as the motor stops, the propeller is damaged, etc., the multi-rotor aircraft at this time can no longer maintain its stable attitude, and it will inevitably fall. Since the multi-rotor aircraft often carries valuable equipment (such as a camera for aerial photography) on it when performing flight tasks, and the value of the multi-rotor aircraft itself is relatively expensive, so once a fall occurs, it will inevitably lead to the loss of valuable ...

AI Technical Summary

Problems solved by technology

When the multi-rotor aircraft is flying, especially at low altitude, once the multi-rotor aircraft fails, such as the motor stops, the propeller is damaged, etc., the multi-rotor aircraft at this time can no longer maintain its stable attitude, and it will inevitably fall.

Since the multi-rotor aircraft often carries valuable equipment (such as a camera for aerial photography) on it when performing flight tasks, and the value of the multi-rotor aircraft itself is relatively expensive, so once a fall occurs, it will inevitably lead to the loss of valuable equipment. Damage to the equipment and the multi-rotor aircraft itself will cause large economic losses. At the same time, after the multi-rotor aircraft falls from a high altitude, it may also cause damage to personnel and other equipment on the ground

[0003] In today's technology, some operators also protect the multi-rotor aircraft by fixing parachutes on the multi-rotor aircraft, but in actual operation, since the parachute takes a certain time to open, if the multi-rotor aircraft fails when flying at low altitude, The multi-rotor aircraft will also fall due to the parachute not opening in time

Therefore, in the prior art, there is no mature and practical device or method to protect the multi-rotor aircraft in flight, especially low-altitude flight.
