Definitions
- the invention relates to an artillery rocket according to the preamble of the claim 1.
- the generic artillery rocket is known from DE 4325218 C2. It deals is about an MLRS1 missile, which is used to increase coverage with Canards Is provided; by their buoyancy on the ogive of the rocket structure to be able to stretch the descending branch of the ballistic trajectory. So that the fault budget does not increase incompatible, the rocket with a satellite navigation system to correct the current trajectory in Equipped with the given target coordinates. The orbit correction takes place dynamically by variable employment of the Canards, depending on the in the course the rolling motion of the rocket in space currently just taken position. Since for a stable trajectory the control of the Canards always the constant rotation the missile must be tracked, but the control effort is considerably and functionally critical. In addition, the space requirement for the installation of the drive means for the constant change of Canardangnagnaric and the on-board energy requirement for this very considerably.
- a pre-launch temping of a time fuse in the tip The rocket giveaway initiated over the finish area, also in the ogive located gas generator for filling a coaxial along the system axis extending through the payload space within the rocket shell Blähschlauches, the paraxial with the increase in its diameter rod-shaped submunitions packed around it from the inside radially outward presses against the rocket shell and this breaks along predetermined breaking points to the Submunition stack laterally deploy.
- the present invention is the technical Underlying the problem, which stored at the user in the depot MLRS-1 artillery rockets with as simple as possible, technologically Risk-free interventions to increase performance with a view to more precise delivery to undergo the submunitions.
- the transverse thrust unit is with an at least single-layer wreath of respect the rocket longitudinal axis radially acting miniaturized pyrotechnic reaction elements fitted.
- a navigation device In front of it in the Ogive is a navigation device.
- the navigation in the sense of tracking the actually flown actual and at least one course correction for the final approach directly to the given one Delivery coordinates are preferably via a conical in the approximately Outer surface of the Ogive recessed winding antenna for receiving the Signals from navigation satellites.
- the current roll position in space which is the impulse direction to perform a given change in direction of the rocket flight by means of a specific the reaction elements not yet consumed in previous corrections determined, is particularly reliable within the course correction unit and in terms of apparatus little expensive in such a known manner by means of a with the rocket rotating, responsive to the earth's magnetic field magnetic sensor to record the periodicity of the time course of its signal amplitude, because it is not dependent on brightness and therefore especially weather independent is working.
- a microprocessor for the comparison to be made repeatedly during the flight of actual and nominal position and for the direction-selective triggering of Transverse response elements for performing identified correction requirements also has the capacity, when reaching the target position easily above the finish area, the signal for igniting the gas generator for deployment to generate the submunition.
- the sketched in axial longitudinal section foremost section of an artillery rocket 11th includes the ogive 13, with a detonator 12 in its tip, until the transition to the hollow cylindrical shell 14 of the rocket body.
- a payload space 15 for axially parallel stacked submunitions extends in itself even into the rear region of the ogive 13 inside. Coaxially through the payload space 15 passes through a tube 16, the over a gas pipe 17 to a pyrotechnic gas generator 18 directly behind the igniter 12 is connected. The gas generator 18 can be initiated by the igniter 12.
- the Gas evolution then inflates the tube 16 and thereby presses the load the payload space 15 radially against the shell 14 of the rocket structure until it Predetermined breaking points ruptures, with which the submunitions transverse to the longitudinal axis 19 of the Rocket 11 are deployed.
- the ogive 13 will be right before the remaining payload space 15 separated to her after emptying here, from the dividing plane 22 ago in the slightly conically tapered interior of the ogive 18th pushed in, an additional, axially thick annular bulkhead 21 as Mounting floor for the functional elements for navigation and course influencing to be able to install.
- This also serves, after installation, the two sub-Ogiven 13a, 13b on both sides of the parting plane 22 back together coaxially to push.
- the annular bulkhead 21 carries the course correction unit 20 in front of a frustoconical shear unit 23 and a wiring board 24. These internals are arranged or formed annularly, so that as outlined the gas pipe 17 from the igniter 12 and the gas generator 18 concentrically through the bulkhead 21 through to the connection of the Blähschlauches 16 in the payload space 15 may extend.
- the shear unit 23 is provided with a ring of - if necessary, as outlined, distributed over several mutually adjacent transverse planes - reaction elements 25 equipped on the basis of pyrotechnic reaction. They can like sketched be installed in a radial orientation. It can be structurally more advantageous but be, the small engines (ie the reaction elements 25) parallel to the axis stack and connect to the windrow channels, which are after a deflection then open in the radial direction through the shell to respond in the shear thrust pulse trigger.
- the direction in which a change in course is caused depends on it in which spatial direction the outgoing direction of the still unused and is now momentarily oriented to be activated reaction element 25.
- This current spatial position is determined by the fact that by means of a on the board 24th contained, preferably magnetically responsive roll position sensor 27 in the Due to the rolling motion of the rocket 11 periodically detecting the Earth magnetic field is registered.
- This periodicity represents the inverse of the duration one revolution of the rocket 11 about its longitudinal axis 19, so that within this Period each angle of rotation with respect to a spatial reference direction with sufficient accuracy can be interpolated in time.
- Signal processor 28 which also contains the navigation data from a satellite receiver 29 conditioned, which is connected to a winding antenna 30, which in a flat circumferential recess 31 in the front part of the ogive 13 is inserted.
- a memory at the signal processor 28 are the coordinates of the target area for the current mission, ie for the deployment of the submunition, given. This specification is quasi-continuous with data on the currently reached position, taking into account the instantaneous trajectory of the rocket 11, compared. Such data is transmitted via the navigation satellite receiver 29 won to the orbit correction in the direction of the given target coordinates if necessary with regard to the system - fixed orientation of the still available reaction elements - just matching spatial position of the rocket 11 initiate at least one of the reaction elements 25.
- circuit board 24 with a power supply 32 (preferably a activatable battery with electronic voltage converter circuit) for the Operation of the described additional components equipped.
- a Zündverteilscrien 33 supplies the initialization connection from the signal processor 28 the still functional, currently released the reaction elements 25 for a certain course influence.
- the igniter 12 is no longer timed, but it is triggered via a firing line 34 from the signal processor 28, when the rocket 11, the predetermined target position for the application of submunitions has reached.
