Retractable Ballistic Correction Servo

Abstract

The invention discloses a telescopic type ballistic correction servo mechanism. The telescopic type ballistic correction servo mechanism comprises a projectile body and rudder faces. The rudder faces follow the frequency of the projectile body to periodically extend out of the projectile body from rudder holes under driving of a control circuit in the projectile body so as to provide acting force and moment force for correction of the postures of the projectile body. The rudder holes formed in the projectile body and a longitudinal shaft of the projectile body are provided with prefabricated rudder deflection angles generating correction force in the radial direction of the projectile body after the rudder faces extend out of the projectile body. The rudder faces penetrate through the projectile body through the rudder holes and are connected with a control circuit through a connecting rod mechanism arranged in the projectile body and used for providing thrust for the rudder faces to stretch out and draw back in the rudder holes. According to the telescopic type ballistic correction servo mechanism, through combination of the two correction rudder faces and the connecting rod mechanism enabling the rudder faces to move, the rudder faces conduct telescopic actions in the flying process of the projectile body, needed correction force is provided, and the effects of ballistic deviation correction and striking accuracy improvement in current rocket projectile guidenization transformation are achieved.

Description

Technical field: [0001] The invention relates to a ballistic correction technology for guided transformation of rockets, in particular to a retractable ballistic correction servo mechanism. Background technique: [0002] Rocket is a kind of conventional ammunition, which has the advantages of dense firepower, light and easy to launch. Due to the influence of initial disturbance, thrust eccentricity, crosswind interference, etc., the impact points of rockets are generally scattered and the combat efficiency is low. If a simple control mechanism can be added to correct the flight trajectory of the projectile during its flight and reduce the spread of the landing point, it can be turned into a precision guided weapon to meet the needs of modern warfare. At present, there are many methods for the guided transformation of rockets, and installing a correction servo mechanism on the head is an efficient and economical method. Invention content: [0003] The technical problem to...
