Abstract:
A control flap unit for a projectile of the type having a rudder carrier extending longitudinally and a plurality of guiding fins attached to the rudder carrier for pivotal movement about respective pivot axes extending perpendicular to the longitudinal axis of the projectile. A sliding sleeve is disposed internally of the rudder carrier for engagement with pivot levers mounted eccentrically with respect to the fin pivot axes so as to move the fins from a folded condition extending longitudinally along the outside of the rudder carrier to an in-flight position extending radially with respect to the rudder carrier. Lateral guide slots are provided in the rudder carrier for guiding the mounting end portions of the fins. Also, curved pivot lever guide slots are provided in the rudder carrier wall for guiding the pivot levers to effect the pivotal movement of the fins in response to longitudinal movement of the pivot levers resulting from engagement with the movable sliding sleeve. These pivot lever guide slots are constructed with an extension forwardly of the lateral slots so as to accommodate attachment and detachment of the fins with fixedly attached pivot levers onto the rudder carrier by merely inserting the pivot levers through the most forward portions of the pivot lever guide slot and then moving the fin into position in the lateral slots where the fins are pivotally connected to the rudder carrier by way of further connecting means through aligned apertures in the fins and the rudder carrier.
Abstract:
A projectile, preferably a rocket with an unfoldable tail or rudder fin unit with a plurality of guiding fins movable between a storage position extending tangentially along the projectile to a flight position extending radially of the projectile longitudinal axis. A sliding sleeve is arranged in the projectile for engagement with pivot levers on the guiding fins so as to maintain the guiding fins in the storage position until a predetermined instant in the launching of the projectile, at which time the sliding sleeve engages the pivot levers to unfold the fins and force them into their flight position. The sliding sleeve is maintained in a first arresting position for holding the pivot levers and guide fins in the storage position by means of a connecting disk abutting the rear end of the sleeve. This connecting disk is attached to the projectile in such a manner that ignition of propellant charge means disposed rearwardly of the disk cause a disconnection of the disk with respect to the projectile, with a consequent falling away of the disk after the projectile has left a gun barrel so that a rocket engine disposed forwardly of the disk can operate unimpeded by the disk. The disk is provided with a throttle opening for accommodating transfer of propellant charge gases to ignite the rocket cruising engine and to assist a compression spring in moving the sleeve rearwardly to unfold the guiding fins. Preferred embodiments utilize the disk arrangement for accommodating the propellant charge initial acceleration and the later operation of the cruising engine with or without the further inclusion of the sliding sleeve for controlling foldable guide fins. Other features include a cup spring arrangement for holding a warhead detonator in position between detachably connected parts of the projectile, as well as novel conduit means for transferring the propellant charge gases to an ignition element for the crusing engine.
Abstract:
A process for the production of explosive devices surrounded by a case wherein an explosive charge is placed in a matrix mold and a pressing tool is moved in one direction of the mold to apply a force to one of mutually opposite end portions of the explosive device formed by the pressing operation. Subsequently, the explosive device is placed in a case having an open end with the other mutually opposite end portion proximate to the open end. A pressing tool is then moved to apply a force to the other mutually opposite end portion of the explosive device such that in the two pressing operations, a pressing tool is effective on the mutually opposite end portions to provide the explosive device with a uniform density. The process also includes the press molding of a detonation inhibiting barrier within the case prior to placing the explosive within the case and subsequently sealing the open end of the case with a sealing member.
