Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, and in particular to a wing-dispersing device. Background Technology

[0002] Equipping glide bombs with wings significantly increases their range, allowing the launching aircraft to strike targets from outside the defended area or briefly enter enemy territory, thus increasing aircraft safety. Currently, glide bombs typically fly towards their targets with their wings intact during the terminal phase of their trajectory. The presence of the wings reduces the bomb's maneuverability and speed, affecting both accuracy and destructive power. Therefore, jettisoning the wing assembly at the terminal phase of the glide bomb's trajectory is chosen to increase both accuracy and destructive power. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-6 As shown, a wing jettisoning device includes a missile body 100, a wing assembly 200, an explosion control assembly 300, and a strap assembly 400. The missile body 100 is a complete guided bomb and serves as a carrier for mounting the wing assembly 200, the explosion control assembly 300, and the strap assembly 400. The wing assembly 200 is strapped to the missile body 100 via the strap assembly 400. The strap assembly 400 includes a right strap 8 and a left strap 9. One end of the right strap 8 and the left strap 9 is fixed to the wing assembly 200, and the other ends of the right strap 8 and the left strap 9 are connected to each other to prevent the wing assembly 200 from moving back and forth on the missile body 100.

[0023] The explosion control assembly 300 includes a battery 2, an initiation controller 3, a cable 4, an initiator 7, and explosive 10. The battery 2 and the initiation controller 3 are installed inside the wing assembly 200. The battery 2 is used to power the initiation controller 3 and the initiator 7. The right band 8 and the left band 9 are provided with protruding cavities. The initiator 7 and the explosive 10 are located in the protruding cavities. Three triangular grooves are opened on the inner wall of the protruding cavities. The initiation controller 3 is connected to the initiator 7 through the cable 4. When the gliding guided bomb reaches the end of its flight, the initiation controller 3 gives the initiator 7 an initiation command through timing control. The initiator 7 ignites the explosive 10. The energy generated by the explosion of the explosive 10 can cut the right band 8 and the left band 9 at the triangular grooves, thereby jettisoning the wing assembly 200. In another embodiment, three triangular protrusions can be provided on the inner wall of the protruding cavity. The energy generated by the explosion of the explosive 10 can form a jet in the area between two adjacent triangular protrusions. According to the preset cutting of the right band 8 and the left band 9, by setting triangular grooves or triangular protrusions, the explosive energy impact on the protruding cavity can be more uniform, and the wing assembly 200 can be more stably jettisoned.

[0024] The missile wing assembly 200 includes a diamond back 1 and missile wings 5. The diamond back 1 is fixedly connected to the missile body 100, and the missile wings 5 ​​are fixedly connected to both sides of the diamond back 1. The diamond back 1 and the missile wings 5 ​​are welded together as one unit.

[0025] The band assembly 400 also includes rivets 6 and fastening bolts 11. The diamond back 1 is provided with mounting grooves for mounting the right band 8 and the left band 9. The right band 8 and the left band 9 are fixed to the diamond back 1 by the rivets 6 and are connected to each other by the fastening bolts 11.
