Description

Technical Field

[0001] The present application relates to the technical field of simulated training ammunition, and in particular to a simulated training ammunition dropped by a drone. Background Art

[0002] Airdrop training with drones is one of the compulsory training subjects for the troops. It is also one of the subjects with high risks and difficulty in simulation training. Especially in the process of organizing the first live ammunition drop, due to the lack of experience of the trainees, it poses a great challenge to the personal safety of the trainees and trainers. At present, the simulated airdrop training uses a simulated airdrop bomb that is similar in appearance and weight to the live ammunition, but does not have the functions of firing and exploding. During training, the trainers cannot grasp the specific time of the ammunition firing and detonation. Therefore, during the live ammunition drop, there are still dangerous situations caused by the operators not mastering the firing and detonation time of the ammunition. Utility Model Content

[0003] In order to facilitate training personnel to grasp the specific time efficiency of firing and detonating drone airdropped ammunition and improve the training effect, the present application provides a simulated training bomb dropped by a drone.

[0004] The above invention objectives of the present application are achieved through the following technical solutions:

[0005] It comprises a touch switch, a fuse, a warhead and a tail fin, wherein the warhead is filled with explosives;

[0006] The touch switch is fixedly arranged at one end of the fuze, the end of the fuze away from the touch switch is fixedly connected to the warhead, and the end of the warhead away from the fuze is fixedly connected to the tail wing;

[0007] The touch switch is coupled with a delay circuit for delaying the triggering of the fuse;

[0008] The fuze is provided with an electric detonator interface, and the electric detonator interface is coupled to the delay circuit.

[0009] By adopting the above technical scheme, the warhead is filled with explosives, and a touch switch is connected to one end of the fuze. The touch switch and the electric detonator interface are coupled to the delay circuit in the fuze. After the electric detonator interface is connected to the electric detonator, the ammunition can be immediately triggered by detonating the electric detonator. When the projectile is dropped, the touch switch touches the ground, and the electric detonator detonates after receiving the electrical signal, thereby triggering the explosives in the warhead to detonate. The delay circuit facilitates trainees to better grasp the specific timing of the firing and detonation of drone airdropped ammunition during training, thereby improving the training effect.

[0010] Optionally, a plastic bushing is provided in the warhead, a plurality of steel balls are movably provided on the outer wall of the bushing, and explosives are filled inside the bushing.

[0011] By adopting the above technical scheme, the plastic bushing can reduce the friction between the internal parts of the ammunition, thereby reducing energy loss and improving the performance and range of the ammunition. The steel ball can improve the trajectory and adjust the center of gravity and flight characteristics of the ammunition, thereby making the flight of the ammunition more stable and improving the hit rate and accuracy.

[0012] Optionally, a plurality of grooves are formed on the inner wall of the warhead, a plurality of the steel balls are movably arranged inside the plurality of the grooves, and the plurality of the steel balls are arranged in a one-to-one correspondence with the plurality of the grooves.

[0013] By adopting the above technical solution, the groove limits the steel ball to ensure that the steel ball will not shift or loosen during the ammunition firing process, thereby maintaining ballistic stability and performance consistency.

[0014] Optionally, the tail wing is made of plastic and is spiral-shaped as a whole.

[0015] By adopting the above technical solution, the tail wing is made of plastic material, which can reduce the overall weight of the ammunition, help improve the payload capacity and flight performance of the drone carrying the ammunition. The spiral tail wing can effectively reduce the interference of air resistance during the descent process, allowing the projectile to maintain stable rotation and falling, thereby improving the airdrop accuracy.

[0016] Optionally, the delay circuit includes a functional module DL55, a delay relay and a touch switch, the electric detonator interface is coupled to the functional module DL55, the VCC end of the functional module DL55 is coupled to the power supply, the delay relay is coupled to the VO output end of the functional module DL55 and then grounded, and the touch switch is coupled to the TG end of the functional module DL55 and then connected to the power supply.

[0017] By adopting the above technical solution, after the VCC terminal of the functional module DL55 is connected to the power supply, the delay relay of the power-on delay closure opens (30s) for countdown, and the drone is used to drop ammunition. When the touch switch touches the ground, the touch switch is closed, the circuit is turned on, and the electric detonator is detonated after receiving the electrical signal, thereby triggering the detonation of the explosives in the warhead.

[0018] Optionally, the functional module DL55 includes a safety switch and a field control, the safety switch is coupled to a main control chip; the IN interface of the functional module DL55 is coupled to the VCC terminal, and the safety switch is coupled to the IN+ interface; the OUT interface of the functional module DL55 is coupled to the electric detonator interface, and the field control is coupled to the OUT- interface; the POW interface of the functional module DL55 is coupled to the TG terminal.

[0019] By adopting the above technical solution, after the VCC terminal of the functional module DL55 is connected to the power supply, the safety switch is started, the main control chip is powered and sends an electrical signal to the delay relay. After receiving the signal, the delay relay starts the countdown. After the countdown ends, the field tube is turned on, the fuze enters the combat state, and after the projectile is dropped, the touch switch at the front end of the fuze touches the ground, and the OUT interface outputs an electrical signal to the electric detonator. The electric detonator explodes after receiving the electrical signal, thereby triggering the explosion of the explosives in the warhead.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The warhead is filled with explosives, and one end of the fuze is connected to a touch switch. The touch switch and the electric detonator interface are coupled to the delay circuit in the fuze. After the electric detonator interface is connected to the electric detonator, the ammunition can be immediately triggered by detonating the electric detonator. When the projectile is dropped, the touch switch touches the ground, and the electric detonator detonates after receiving the electrical signal, thereby triggering the explosives in the warhead to detonate. The delay circuit facilitates trainees to better grasp the specific timeliness of the firing and detonation of UAV airdropped ammunition during training, thereby improving the training effect;

[0022] 2. Plastic bushings can reduce friction between internal parts of ammunition, thereby reducing energy loss and improving the performance and range of ammunition. Steel balls can improve ballistics, adjust the center of gravity and flight characteristics of ammunition, thereby making the flight of ammunition more stable and improving hit rate and accuracy.

[0023] 3. The tail is made of plastic material, which can reduce the overall weight of the ammunition and help improve the payload capacity and flight performance of the drone carrying the ammunition. The spiral tail can effectively reduce the interference of air resistance during the descent process, allowing the projectile to maintain stable rotation and falling, thereby improving the accuracy of airdrops.
