Abstract

One aspect of the present invention provides a device for sealing a bearing assembly of guiding kit for a projectile. The guiding kit has a rear unit and a front unit rotatably connected to the rear unit. The device includes an annular body and a flexible ring-shaped strip attached to an inner side and close to a front end of the annular body. The ring-shaped strip is adapted to seal a gap between the rear unit and the front unit of the guiding kit at a connection region therebetween. The annular body is adapted to slide towards the rear unit of the guiding kit when subjected to a longitudinal acceleration that exceeds a predetermined acceleration value, thereby uncovering the gap and enabling uninterrupted rotation of the front unit with respect to the rear unit of the guiding kit.

Abstract

A guiding assembly is adapted to be connected to a projectile and comprising a rear main unit adapted to be connected to the front end of the projectile, and a front main unit rotatably connected at its rear end to the front end of the rear main unit. The front main unit is adapted to rotate about a central longitudinal axis. A relative speed control unit is operable between the rear main unit and the front main unit and capable of providing spin braking force to slow the relative speed of rotation of the front main unit. An at least one guiding fin radially extends from the front main unit. The pitch angle of the fin is controllable by a return spring connected to the fin so that the pitch angle of the fin is growing as the aerodynamic pressure on the fin lowers and it is growing smaller as the aerodynamic pressure on the fin gets bigger.
