Detailed ways

As shown in FIG. 1 , in one embodiment of the present invention, the aircraft model intercepting device of the present invention is composed of a launching device, an intercepting net 5 and a projectile 7 . The launching device sends the intercepting net 5 to the target aircraft model 6 by means of the launching bomb 7 . Wherein, the launching device is made up of aiming device 1, launching seat 2, intercepting net box 3, launching rack, three launching tubes 4 and triggering device 8. Wherein, the intercepting net box 3 is arranged on the top of the launching frame for placing the intercepting net 5; the launching frame is composed of a central axis 9 with a cursor 11 and three brackets 10 correspondingly connected with three launching tubes 4 respectively, It is used to support the launch tube 4 and the intercepting net box 3, and to adjust the opening angle between the three launch tubes 4.

The central axis 9 of three launching tubes 4 and the launching frame is installed on the launching seat 2 through the connecting device, the aiming device 1 is arranged on the launching seat 2 , and the trigger device 8 is arranged on the bottom of the launching seat 2 . One end of the three brackets 10 is connected with the vernier 11 , and the other end is respectively hinged with the three launch tubes 4 through the connector 12 . Wherein, a scale can be set on the central axis of the launching rack, so as to determine the position of the cursor 11, thereby adjusting the opening angle between the three launching tubes 4 through the movement of the cursor 11, that is, controlling the opening size of the intercepting net. After the angle is determined, the cursor is locked.

Assuming that the trajectory of the bullet is a straight line, the angle formed by the central axis of the launcher and the launch tube in the projection of the front view of the launcher is θ, the distance between the launcher 2 and the target aircraft model 6 is 1, and the width of the interception net 5 is L . When the interception net 5 captures the target aircraft model 6, the opening range is set to about 2/3 of the net width. According to the relationship of the trigonometric function, $\mathrm{tg\θ}=\frac{\frac{\frac{2}{3}L}{2}}{l}=\frac{L}{3l},$ so $\mathrm{\θ}=\mathrm{arctg}\left(\frac{L}{3l}\right).$

Therefore, when setting the scale, mark the scale according to the distance between the target model airplane 6 and the launch seat 2. The farther the distance between the target model airplane 6 and the launch seat 2 is, the smaller the angle θ is, and the smaller the scale value is. The closer the distance is, the larger the θ angle is, and the larger the scale value is. The scale value here can be scaled according to the distance between the target aircraft model 6 and the launching seat 2, or according to the size of the θ angle, as long as the position of the cursor corresponds to the angle, and the specific situation can be adjusted according to actual needs. design.

The interception net box 3 is placed on the top of the launching rack central axis 9, and is used to place the interception net 5, and the launcher 7 is placed on the top of the launch tube 4, wherein the solenoid valve or ignition device of the launcher 7 It is connected to the trigger device 8 by wires. The corners of the intercepting net 5 are connected with the projectile 7, so that the intercepting net 5 can be launched and opened together with the projectile 7, so that the target aircraft model 6 can be captured by the intercepting net 5. An elastic connector, such as a spring, can be used to provide a cushioning effect between the projectile 7 and the projectile 7 of the intercepting net 5 and the projectile 7 . The intercepting net 5 can also be connected with the launching device by a rope, and is used for recovering and controlling the captured target aircraft model 6 .

Among them, the projectile has a certain quality, and the settings can be adjusted according to actual needs, so as to ensure that the projectile can overcome the launch resistance and drive the intercepting net to reach the target position. Among them, the intercepting net is made of metal, glass fiber reinforced plastic, ceramics, nylon, etc., which are wear-resistant and not easy to damage materials, single or composite.

After finding the target model airplane 6, set the angle of the launcher on the launching seat 2, aim at the target model airplane 6 through the aiming device 1, start the trigger device 8, launch the projectile 7, and drive the intercepting net 5 to fly to the target model airplane 6. When capturing the target model airplane 6, due to the inertial effect of the projectile 7, the angle of the interception net 5 will be closed and entangled with the target model airplane 6, and the target airplane model 6 will be controlled by the recovery rope, thereby realizing the interception task of the airplane model.

Compressed gas cylinders and airbags can also be set in the projectile. When the intercepting net 5 catches the target aircraft model 6, under the pulling force of the intercepting net 5, the compressed gas cylinder can be opened, and the compressed gas therein can be charged to the airbag, so that The intercepting net 5 and the target model airplane 6 are floating in the air, so as to be beneficial to control and recover the target model airplane 6 .
