Problems solved by technology

At present, the layout of the wings of the two-wing parachute-free terminal-sensitive projectiles researched in China is basically two wings of different sizes symmetrically distributed on both sides of the projectile body, such as figure 1 As shown, the asymmetry of the aerodynamic force generated at this time and the rotational speed of the submunition are relatively small, and it is difficult to realize the steady-state scanning of the terminal sensitive submunition, which has limitations such as too short scanning time in the air and too slow rotational speed.

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0015] The shape and mass of the double-winged terminal-sensitive bullet without parachute are artificially asymmetrical, and the asymmetry of the aerodynamic force and inertia tensor is used to form a certain form of movement of the bullet's longitudinal axis relative to the velocity vector on the ballistic trajectory, so as to achieve the target area. Steady state scan. The main contribution of the aerodynamic force of the double-wing non-parachute terminal-sensitive bomb comes from the two fins. The scanning time of the double-wing non-parachute terminal-sensitive submunition in the air is proportional to the aerodynamic force of the terminal-sensitive bomb, and the scanning speed is proportional to the rotational moment coefficient of the submunition.

Abstract

The invention relates to double-wing non-parachute terminal sensing ammunition which comprises a projectile body (1), a large wing (2) and a small wing (3), wherein the large wing (2) and the small wing (3) are arranged at the two sides of the projectile body (1) in a staggered manner; a connection position of the large wing (2) and the projectile body (1) is positioned on the top of the projectile body (1); the large wing (2) deviates to left by 1 / 3 and deviates to right by 2 / 3 relative to the axis of the projectile body (1); and a connection position of the small wing (3) and the projectile body (1) is positioned on the top of the projectile body (1), and the small wing (3) deviates to left by 2 / 3 and deviates to right by 1 / 3 relative to the axis of the projectile body (1). According to the double-wing non-parachute terminal sensing ammunition, a resistance coefficient is increased by about 10%, a rotating torque coefficient is doubled, and steady-state scanning time and rotation speed of the non-parachute terminal sensing ammunition are improved.

Description

technical field [0001] The invention belongs to the field of weapons, and in particular relates to an airfoil layout design of an umbrella-free terminal-sensitive submunition. Background technique [0002] The terminal sensitive bomb is called "the nemesis of cluster tanks". Foreign countries began to develop terminally sensitive submunitions in the 1980s. At present, the terminal-sensitive bombs developed by most countries mainly use vortex parachutes to realize the steady-state scanning of the missile body, and my country has also realized engineering applications in the terminal-sensitive bombs with umbrellas. However, the use of umbrella scanning has greatly affected the overall combat effect of terminal sensitive bombs due to obvious shortcomings. In order to improve the overall combat effect of terminal-sensitive bombs, it is necessary to explore and develop new and more advanced steady-state scanning technologies, mainly to increase its rotational speed and falling ...
