Embodiment 1

[0041] Embodiment 1: The unmanned aerial vehicle and the aircraft fly opposite to implement interception, and the friction force between the tow in the tow curtain and the propeller shaft makes the propeller stop, and intercepts the unmanned aerial vehicle.

[0042] The known condition is: the wingspan of the intercepted aircraft w o = 2m, speed v t =50m / s; UAV speed v b =20m / s; the maximum wind speed v that the fiber tow curtain can withstand w =10m / s, the average wind speed v after the fiber tow throwing device throws the tow wv = 5m / s. The specific design process of the fiber tow curtain is as follows:

[0043] (1) take μ o =20, according to formula (1), initially determine the width w ' of the fiber tow curtain as (unit: meter):

[0044] w'=μ o w o =20×2=40

[0045] (2) take v d =5m / s,μ w =0.5, determine the design height h of the tow curtain according to formula (2) as (unit: meter):

[0046] h = w ...

Embodiment 2

[0062] Embodiment 2: The unmanned aerial vehicle and the aircraft to be intercepted fly towards each other to implement interception. During the interception process, the tow curtain thrown by the UAV is used as a carrier, and a specially designed small bomb with a time-delayed fuze is mounted on it. The shock wave generated by the bomb explosion and the destruction of the aircraft body are used to intercept the aircraft. The tow curtain design process and interception process are the same as in Embodiment 1.

Embodiment 3

[0063] Embodiment 3: The unmanned aerial vehicle and the aircraft to be intercepted fly towards each other to implement interception. During the interception process, the tow curtain thrown by the UAV was used as a carrier, and the drag parachute was mounted on it. The unbalanced resistance of the drag parachute caused the attitude of the aircraft to change drastically, resulting in the failure of the autopilot of the aircraft and the crash of the aircraft. The tow curtain design process and interception process are the same as in Embodiment 1.

Abstract

The invention discloses a method for intercepting aircrafts without collateral damage in an unmanned way. The design scheme of the method mainly comprises five steps: confirming the designed width and height of a fiber bunch curtain which is unfolded, revising the designed width, confirming the conditions for the rendezvous of the fiber bunch curtain and the aircraft, and throwing fiber bunches with an unmanned aerial vehicle. When confirming the rendezvous conditions, the relative height in the vertical direction, the relative distance in the airway direction and transverse errors in the vertical direction of an airway between the unmanned aerial vehicle and the aircraft need to be measured; the function of the fiber bunch curtain in intercepting the aircraft can be strengthened by hanging and loading various agents; and in order to enhance the intercepting reliability, a plurality of unmanned planes can be applied to form a plurality of fiber bunch curtains in air simultaneously so as to intercept the aircraft. The method adopts a soft killing way to intercept the aircraft, thus realizing shoot straight; intercepting equipment is convenient to use and maintain; and additional damage in the intercepting process is avoided, and the environment pollution and safety threats are avoided. The complexity of an intercepting system adopting the method is low, thus being beneficial to mass equipment.

Description

technical field [0001] The invention relates to a method for unmanned interception of an aircraft without incidental damage, in particular to a method for an unmanned aerial vehicle to intercept an aircraft by throwing a fiber tow curtain, and belongs to the field of urban air security. Background technique [0002] In some important occasions such as large-scale sports games, conferences, or in the case of war, in order to prevent hostile forces or the enemy from using drones, cruise missiles and other aircraft to destroy meeting venues or important event venues, it is necessary to detect incoming aircraft to intercept. The interception of the aircraft can adopt the hard killing method of directly hitting the aircraft, such as precise strikes on the aircraft with missiles and artillery shells, but the hit rate of this method is low, and a large number of fragments generated after the attack is completed are likely to accidentally injure irrelevant personnel, causing damage ...
