摘要:
A folding wing (2) for a missile comprises a wing root (6), an upper wing part (4) foldably supported at the wing root (6) around a swiveling axis (10), at least one first elastically pre-stressed force element and a latching device. The at least one first elastically pre-stressed force element (42) is coupled with the wing root (6) and the upper wing part (4) and is designed for permanently urging the upper wing part (4) into a working position relative to the wing root (6) through introducing a torque. The latching device is designed for arresting the upper wing part (4) on reaching the working position automatically.

An apparatus (14) and method for guiding a cannon shell accurately are disclosed. The apparatus includes two main parts (21) adapted to be installed on the leading end of the cannon shell. The front main part of the apparatus is equipped with at least one pair of fins and is rotatable with respect to the rear main part. The pair of fins is controlled to hold the front main part substantially stable with respect to an external reference frame when the cannon shell rotates as it flies towards its target. Control system is comprised within the apparatus that receives location signals and is adapted to provide guiding control commands to the cannon shell via the fins so as to guide the shell accurately to its preprogrammed target. The control system is adapted to activate the detonation chain of the shell according to preprogrammed mode.
摘要:
A folding wing (2) for a missile comprises a wing root (4), an upper wing part (6) foldable relative to the wing root (4), at least one guiding device (22, 24), and an elastically pre-stressed force element (48). The foldable upper wing part (6) comprises an end edge and a profile foot (10), wherein the wing root (4) comprises a base (26) and a receiving groove (12) opposite thereto, which receiving groove (12) is designed corresponding to the profile foot (10) at least in a ground (13) of the groove for receiving the profile foot (10) in a flush manner and is delimited by two delimiting edges (14, 16), which comprise a distance to each other, which at least equals the maximum profile thickness (36) of the profile foot (10). The at least one guiding device (22, 24) is arranged at one of the upper wing part (6) and the wing root (4) and is designed for guiding the profile foot (10) in a variable distance to the ground (13) of the receiving groove (12). The elastically pre-stressed force element (48, 50, 54, 56) is coupled with the wing root (4) and the upper wing part (6) and urges the upper wing part (6) into the receiving groove (12) through the pre-stress.
摘要:
The invention relates to a fin deployment mechanism (10, 20) for a rotationally stabilized projectile (1), comprising at least one fin (2, 15) and at least one actuator, in which the fin (2, 15) is arranged in a deployable and retractable manner on the projectile (1), and in that the fin (2, 15) and at least one balance weight (3, 17) are mechanically arranged so that, when the fin (2, 15) is deployed by the actuator, then the balance weight (3, 17) is displaced in towards the centre (6) of the projectile (1) and, when the fin (2, 15) is retracted by the actuator, then the balance weight (3, 17) is displaced out from the centre (6) of the projectile (1). The invention also relates to a method for energy-efficient deployment and retraction of fins (2, 15) on a rotating projectile, in which at least one fin (2, 15) is arranged in a deployable and retractable manner on the projectile, and in which the fin (2, 15) is fitted to at least one balance weight (3, 17) according to: (a) when the fin (2, 15) is displaced out from the centre of the projectile, upon deployment of the fin (2, 15), the balance weight (3, 17) is displaced in towards the centre of the projectile, (b) when the fin (2, 15) is displaced in towards the centre of the projectile, upon retraction of the fin, the balance weight (3, 17) is displaced out from the centre of the projectile.
摘要:
A system and methods for fluid dynamically controlling a projectile (100) are disclosed. At least one actuator (118) coupled to at least one common actuation structure (108) is actuated to provide an actuation force via the common actuation structure. The actuation force is transferred through at least one linkage structure to at least one fluid dynamic control surface (106) coupled thereto.
