Description

[0001] The present invention relates to a fuse coupling device for launch vehicle,

[0001] The present invention relates to a new pipe coupling device for a projectile, and more particularly to a pipe fitting device for a projectile which is easy to arrange warheads.

The fuse is a device that ignites explosives filled in bullets, bombs, and torpedoes. Depending on the function, there are various methods such as perception, delay, deadline, proximity, and control fuse, and there are percussion, inertia, electricity, clock, radio wave, magnetism, sound and pressure fuse. In general, the fuselage of a shell is a proximity fuselage that is detonated during flight according to a target detection method, a shock fuselage which is exploded by the impact after impact, and a fusing fuselage which is delayed after a certain delay after a target penetration or target penetration.

For launch vehicles with induction-type ammunition, the torso and the fuselage are kept separate and combine the torso and the fuselage just before launch. A flight control device is installed inside the new pipe of the projectile, and the flight control device is composed of various sensors such as a gyro sensor, an acceleration sensor, a magnetometer, and the like.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a photograph showing a cross section of a conventional joint between a new tube and a torus.

Referring to FIG. 1, the coupling between the body and the main pipe is performed by the coupling of the threads 12 and 14 due to the rotation of the coupling housing 10, in which alignment between the sensors and the control vane is essential. This is because the errors are reduced when the sensors are correctly aligned during operation of the control wing for initial posture calculation and route flight after launch.

In addition, in the case of a flying body equipped with a glide wing for extending a range, the alignment of the pilot wing, the flight control device of the new pipe and the glide wing should be more accurately performed.

However, this thread engagement may occur at the original alignment position due to rotation, which may affect the alignment accuracy. Therefore, calculation of the initial attitude of the projectile and error of the route flight may occur, which may deteriorate the performance of the projectile.
