Low-altitude aircraft intercepting device

Abstract

The invention provides a low-altitude aircraft intercepting device. The device comprises an intercepting net, at least one automatic air bag and at least one excitation device; the automatic air bagsare controlled by electromagnetic valves to be inflated, the automatic air bags and the excitation devices are fixed on the intercepting net, when the low-altitude aircraft intercepting device intercepts an aircraft, the excitation devices control the automatic air bags to be inflated, the impact force when the intercepting net falls to the ground can be effectively reduced by utilizing the inflated air bags, the falling speed of the intercepting net of the aircraft can also be slowed down, secondary disasters such as aircraft explosion and the like can be effectively prevented, the safety ofground personnel and facilities can be protected, the safety problem which cannot be solved by an existing interception method is solved, and the method is easy to implement, high in reliability and wide in application prospect.

Description

technical field [0001] The invention relates to a low-altitude aircraft intercepting device, which mainly involves technologies such as automatic control and machinery. Background technique [0002] Low-altitude aircraft include rotary-wing unmanned aerial vehicles, fixed-wing unmanned aerial vehicles, balloons, etc. Such aircraft have low flying height, small size, and low cost, and have been widely popularized and used in the world. a great threat. At present, the commonly used interception methods for low-altitude aircraft include fire interception, laser strike, radio interception, radio jamming, drone countermeasures, and interception nets. Fire interception is to use rockets, light missiles and other weapons to attack low-altitude aircraft, but weapons and ammunition are relatively destructive, and ammunition and aircraft fragments are easy to cause damage to ground personnel and facilities, so they can only be used in open and unmanned areas; laser Strike is to use ...

AI Technical Summary

Problems solved by technology

Fire interception is to use rockets, light missiles and other weapons to attack low-altitude aircraft, but weapons and ammunition are relatively destructive, and ammunition and aircraft fragments are easy to cause damage to ground personnel and facilities, so they can only be used in open and unmanned areas; laser Strike is to use laser weapons to burn drone parts and make drones fall; radio interception is based on radio interference, using the same flight control signal as drones to control drones to land. This method is only applicable to specific Some drones of known models; radio interference is to interfere with and suppress the radio flight control signal of the aircraft, causing the drone to lose control and fall. This method is only applicable to aircraft that use radio flight control, and cannot intercept aircraft with autonomous navigation functions. UAV countermeasures use larger UAVs to directly intercept or hit the target aircraft in a self-destructive manner. After interception, both the combat UAV and the target aircraft will crash on the ground; Interception net disables aircraft

In addition to radio interception which can control the soft landing of UAVs, other existing interception methods cannot control the falling process and landing site of the intercepted aircraft. When the aircraft crashes, due to the strong collision with the ground, it is easy to cause the explosion of the power system and cause secondary disasters. , pose a serious threat to the safety of ground personnel and facilities

In order to solve this problem, parachutes are added to some interception nets, but the opening speed of the parachute is slow. In many cases, the aircraft has fallen to the ground before the parachute is opened, and the reliability is poor.
