Projectile body structure for improving aerodynamic stability of non-rotating projectiles

Abstract

The invention discloses a projectile body structure for improving aerodynamic stability of non-rotating projectiles. The projectile body structure comprises a projectile head, wherein the projectile head is in a shape of a conventional projectile head; a middle-rear section of the projectile head is connected with a projectile wing part; the projectile wing is in a projectile body embedding form; the projectile wing comprises four wing surfaces; the wing surfaces are separated by four transition steps; each transition step is composed of two conical surfaces; each conical surface comprises a small-cone-angle conical surface and a large-cone-angle conical surface; the rear part of each large-cone-angle conical surface is connected with a cylindrical part of the projectile body; and the diameter of each cylindrical part is equal to that of the projectile body. The invention aims at the problem of insufficient stable storage quantity of non-rotating and hypersonic launched projectiles and considers the limitation of a launching system on the projectile size; four projectile wings are formed in an embedded mode, and air flow is guided through the transition steps, so that the static stability of the projectile bodies is improved under the hypersonic flight conditions of the projectiles; and the flight stability is ensured.

Description

technical field [0001] The invention relates to the field of projectile aerodynamic structures, in particular to a projectile structure for improving the aerodynamic stability of non-rotating projectiles. Background technique [0002] Nowadays, three-dimensional warfare has higher and higher requirements for space and time, and the requirements for range and accuracy of weapon systems are becoming more and more urgent. At the same time, weapon systems are required to respond faster and have a higher rate of fire. The higher the muzzle velocity of the projectile means the farther its range is. Under the premise of a certain range, a higher muzzle velocity means shorter flight time and greater power, which can improve the hit rate and damage to the target. [0003] With the emergence of launch technologies such as electromagnetic coil acceleration and electromagnetic orbital energy, the muzzle velocity of projectiles can reach more than 2000m / s or even higher. If fired at hyp...
