Definitions
- the fold-out fins can be folded in during the ascent phase, the tilt-over maneuver phase and the ballistic phase and thus (at least largely) aerodynamically ineffective, while they can be unfolded during the aerodynamic descent phase, the braking phase, the approach phase and the landing phase can to bring about the desired aerodynamic influence.
- the fins can be designed, for example, as so-called grid fins or as flat fins (so-called “plain fins”).
- the influence of the fin (in addition to the geometry of the fin itself) on the flow conditions of the missile is dependent on an angle of attack of the fin with respect to the flow around the missile.
- the fins serve to ensure and / or improve the stability of the missile and / or to control the same in atmospheric flight phases.
- the fins may be folded out in order to be able to bring the fin into effect only selectively in certain flight phases.
- it may be necessary to fold in the fins in order to minimize a negative effect of the unfolded fin on the aerodynamic properties of the missile (for example an undesired additional drag or a destabilizing effect) in the take-off phase. Folding in the fins may also be necessary to bring the missile into a spatially compact state with the fins folded in, which can be advantageous for storing and / or transporting the missile and / or for launching the missile from a launch canister or launch shaft .
- the present invention relates to a missile-fin deployment device which enables a fin to be folded out.
- the invention also relates to a missile with such a missile-fin deployment device.
- the invention also relates to a method for operating a missile with a missile fin deployment device.
- WO 2014/197046 A2 discloses a missile designed as a projectile, in which fins are arranged in the rear end region of the missile.
- the fins can be pivoted about an axis oriented parallel to the longitudinal axis of the missile.
- the fins are integrated into the surface of the missile in such a way that a longitudinal axis of the fin is oriented in the circumferential direction or tangential to the surface of the missile, while one is oriented parallel to the transverse axis of the fin in the longitudinal direction of the missile.
- WO 2008/147453 A2 also discloses a pivoting of fins arranged in the rear end region of a missile designed as a projectile about pivot axes which are oriented parallel to the longitudinal axis of the missile.
- WO 2008/147453 A2 also proposes an embodiment in which the fins are arranged in radial shafts in the rear end region of the missile. In the folded-in position, the fins are initially held in the shafts by means of a holding device.
- the fins are in the radially outer one
- the end region is mounted so as to be pivotable about a pivot axis which is oriented tangentially to the circumferential direction of the missile.
- the holding effect of the holding device can be overcome by means of centrifugal forces exerted on the fins as a result of a rotation of the missile, whereby the fins can be folded out radially outward about the pivot axis from the shafts.
- EP 2 433 084 B1 discloses a missile which, on the one hand, has fins serving for roll stabilization in the rear end area, which are received in radial slots and can be pivoted outward about a pivot axis that is oriented tangentially to the surface of the missile.
- the fins are spring-loaded in the direction of pivoting out, the fins initially being prevented from pivoting outwards by a lock. The locking mechanism is destroyed when the fins are swiveled out by the springs.
- the missile has centrally arranged pivotable wings which, in the pivoted-in state, are also received in radial slots of the missile and can be pivoted out about a pivot axis oriented transversely to the longitudinal axis of the missile.
- the wings are swiveled out when the missile in the form of a projectile emerges from the muzzle or after the highest point of the ballistic phase has been reached.
- a tail section of the missile with the foldable fins is rotatably connected to a front section of the missile with the wings via a coupling in the released state of the coupling.

- the fins are pivoted out about pivot axes which are oriented tangentially to the circumferential direction of the missile.
- EP 1 485668 B1 proposes to ensure that the fins can be unfolded by means of an actuating mechanism in which the degree of freedom of the fins for unfolding on the one hand a rotation and on the other hand, a pivoting of the fin are superimposed.
- the extends Fin In the folded state, the extends Fin with the longitudinal axis in the longitudinal direction of the missile and the transverse axis tangential to the circumferential direction of the missile.
- the longitudinal axis of the fin extends radially to the missile or normal to the surface of the missile, while the transverse axis of the fin extends parallel to the longitudinal axis of the missile.
- a link guide Via the degree of freedom of the fin, the dependency of the pivot angle of the fin and the angle of rotation of the fin during unfolding is clearly specified by a link guide.
- the movement along the degree of freedom is brought about by a pretensioned spring, this movement being supported during the unfolding also by the flow around the missile and the fin. Contrary to the action of the spring, the fin is held in the folded position by an unspecified locking mechanism.
- US 2009/0126523 A1 discloses an extension mechanism for a control surface.

- the extension mechanism can also be used for a projectile, which can be arranged in a launch barrel with the control surface retracted, while the control surface can be extended by the extension mechanism during flight operations in order to influence the trajectory of the projectile. By extending the control surface, the surface properties of the projectile can be modified for the purpose of influencing the trajectory of the projectile.
- the control surface can allow two alternative surface characteristics or a larger number of them.
- the extension mechanism is arranged in a transverse bore of a base body of the projectile.
- the extension mechanism has an electric motor whose drive pinion can be rotated around the longitudinal axis of the projectile.
- the drive pinion meshes with a driven gear, the axis of rotation of which is oriented parallel to the longitudinal axis of the projectile.
- the output gear drives a shaft, the rotational movement of which is converted into a translational movement of the control surface body transversely to the longitudinal axis of the projectile.
- the motor with the drive pinion can be displaced relative to the output gear and a likewise driven by the motor drive bevel gear can engage in a Abtriebske gelrad, whose rotational movement about the translational movement axis of the Steuer vomkör pers is transmitted to the control surface body.
- No. 6,726,147 B1 proposes a mechanism which enables both a change in the angle of attack of a thrust reversing vane and the extension of a fin to take place by means of a single actuator.
- the actuator drives a spindle which meshes with a spindle nut which is held by the end region of a crank.
- the crank is coupled to a holding body of the fin via a coupling.
- the crank is coupled via the coupling to a four-bar chain, which can be used to rotate the thrust reverser blade.
- the coupling has two drivers which are formed by a locking body Ver.
- the drivers are each ge leads in a T-shaped guide.
- the vertical leg of the T is oriented in the circumferential direction around the holding body and limited on one side by the crank and on the other side by a crank of the four-bar chain.
- the vertical leg of the T is oriented in the longitudinal direction of the holding body.
- One leg of the horizontal leg is formed by the crank and the other leg of the horizontal leg is formed by the crank of the four-bar chain.
- the locking body with the drivers is also acted upon by a pretensioned compression spring in the direction of its longitudinal axis.
- the locking body rests with an end face away from the pivot axis of the fin on the holding body on the fin.
- a first adjustment range of the actuator in which the driver moves in the area of the circumferentially oriented vertical leg of the T of the guide, no expansion of the spring is possible as a result of the guide, so that the fin cannot leave the folded position.
- the actuation of the actuator leads to a change in the angle of attack of the thrust reversing vane. If, however, the driver at the end of this adjustment area in the area of the horizontal leg of the guide, the compression spring can extend the locking body, so that the fin is folded out about its pivot axis. During this unfolding, the driver moves along a partial limb of the horizontal limb of the T-shaped guide. An actuation of the actuator that then takes place after the unfolding has been completed can be used to pivot the holding body with the fin about the longitudinal axis.
- the invention is based on the object of proposing a missile-fin unfolding device which is improved in particular with regard to the aerodynamic effects that can be brought about, the actuation, the possibilities of influencing the aerodynamic effects that can be brought about and / or the reliable support of the fin in the unfolded state. Furthermore, the invention is based on the object of proposing a missile with a correspondingly improved missile-fin deployment device. Finally, the invention is based on the object of proposing an improved method for operating a missile with a missile-fin deployment device.
- the invention proposes a missile-fin unfolding device which has an actuating mechanism by means of which a fin can be unfolded relative to a missile equipped with the missile-fin unfolding device and in this way can be brought into effect aerodynamically.
- This can be a fin of any type, in particular a flat fin or a lattice fin.
- the actuating mechanism has two degrees of freedom for unfolding the fin. These degrees of freedom are a degree of torsional freedom via which the fin can be rotated about its longitudinal axis, and a pivoting degree of freedom via which the fin can be pivoted about a transverse axis. According to the invention, the two degrees of freedom are independent of one another.
- the aerodynamic effect of the fin can also be influenced during flight operations by using at least one degree of freedom. For example, it is possible that, depending on the flight conditions and / or flight phase, an angle of attack of the fin is changed with respect to the flow, for example by rotating the fin in the swiveled-out state into different flow positions. Here, even the rotation can be used to control or regulate the flight characteristics.
- the missile-fin deployment device according to the invention has a missile-holding area, via which the missile-fin deployment device is held, in particular supported and / or stored, on the missile. Furthermore, the missile fin deployment device has the actuation mechanism.
- the fin is held on the missile holding area via the actuation mechanism.
- the actuation mechanism is used to rotate the fin on the one hand with respect to the missile holding area or the lateral surface of the missile about an axis of rotation and on the other hand to rotate the fin to pivot about a pivot axis relative to the missile holding area or the lateral surface of the missile.
- a pivoting degree of freedom and, on the other hand, a rotational degree of freedom are provided by means of the actuating mechanism, wherein the actuation along these two degrees of freedom can take place independently of one another.
- the actuating mechanism has the rotating mechanism on the one hand. By means of the rotation mechanism, the fin can be rotated about the axis of rotation with respect to the missile holding area.
- the actuating mechanism has the pivoting mechanism.
- the fin can be pivoted about the pivot axis with respect to the missile holding area.
- the twisting mechanism and the pivoting mechanism can be actuated independently of one another, which takes place in particular by separate and independent control of a rotary actuator acting on the twisting mechanism and a pivoting actuator acting on the pivoting mechanism.
- the twisting mechanism and the pivoting mechanism can be designed as desired and can be integrated into the missile-fin deployment device.
- the twisting mechanism and the pivoting mechanism are interposed with respect to the flow of force in a mechanical series connection between the fin and the missile holding area. The consequence of this is that the fin is supported on the missile holding area via the twisting mechanism and via this on the pivoting mechanism (or vice versa).
- the rotation mechanism is also pivoted (or with the rotation of the rotation mechanism, the pivoting mechanism is also pivoted).
- any swivel mechanism can be used within the scope of the invention, for example swiveling via a conventional swivel bearing with a rotary swivel drive which brings about the swiveling and which can swivel one of the wasted parts directly or with the interposition of a gear stage.
- the pivoting mechanism has a link guide.
- the link guide can be used to convert any kind of movement of a swivel actuator into a swivel movement, the dependence of the movement of the swivel actuator and the pivoting being able to be specified by the contouring of the link guide.
- the use of the link guide is advantageous in terms of the possibilities for designing the swivel characteristics.
- the pivoting mechanism can have an actuator which triggers and / or brings about the pivoting of the fin.
- the actuator is preferably a translational actuator, by means of which, for example, an actuating element (such as, for example, pushing and / or pulling element) is actuated, which ultimately brings about the pivoting of the pivoting mechanism.
- an actuating element such as, for example, pushing and / or pulling element
- the movement of the translational actuator can bring about a movement of the pivoting mechanism along the link guide.
- the actuator it is possible for the actuator to have a spring device with one or more springs of any design.
- the spring device is tensioned in the pivoted-in position of the fin.
- the tension of the spring represents an energy store.
- the energy of this energy store can then be used to generate the pivoting movement.
- the spring device In the pivoted-in position, the spring device can be latched or locked via a latching or locking device. The rest or
- the locking device can be unlocked or unlocked. With the unlocking of the locking device or the unlatching of the latching device, the energy of the spring device is released, with which the spring device can pivot out the fin.
- Delimbing or unlocking may require less energy than the energy required to swing the fin out.
- the spring device can be tensioned with the pivoting in of the fin manually or via a separate tensioning device before the missile is launched, and the missile only has to carry a small release device that requires little energy.
- the actuator is a preferably electric drive which generates the translational movement of the actuating element or some other movement which then results in the pivoting mechanism being pivoted.
- the pivoting mechanism has a pivot bearing body, with respect to which the fin can be pivoted.
- the link guide between the fin and the pivot bearing body can be effective.
- the fin is supported (with regard to pivoting about the pivot axis) on a support and / or holding device on the pivot bearing body.
- this support and / or holding device only comes into effect when the pivoted-out position is reached and in this position in addition to other supports or articulations.
- the support and / or holding device can ensure a stiff and reliable support in the pivoted-out position in which the fin is exposed to considerable aerodynamic forces under certain circumstances.
- the support and / or holding device can be designed as a stop or contact surface. It is also possible that in the swiveled-out position the fin or a holding element of the same is drawn in between contact surfaces, in a holding recess, for example of a guide tube or a guide cone, with which a form-fitting support of the fin on the pivot bearing body can then be ensured.
- the swivel bearing body prefferably be rotatable relative to the missile via a rotating mechanism.
- the pivot bearing body has a holding recess into which the fin enters in the direction of actuation of the pivot actuator. The fin is then secured in the swiveled-out state in a form-fitting manner in the holding recess.
- the holding recess and / or the fin preferably have tapering holding surfaces. If the movement of the fin into the holding recess occurs with the actuation of the swivel actuator, the tapering holding surfaces can result in tensioning between the holding surfaces or jamming between them. It is possible that a kind of self-locking occurs on the tapering holding surfaces (depending on the friction conditions and the angle of inclination of the tapering holding surfaces), which secures the fin in the holding recess and in the pivoted-out position.
- the fin is held in the pivoted-in position (preferably exclusively) via the link guide and the articulation of the actuator, whereby the pivoted-in position is secured.
- the support and / or holding device in the swiveled-out position, there is also the link guide and the articulation of the actuator, the support and / or holding device to the effect, which has the consequence that the support and / or holding device can at least partially relieve the link guide and / or the linkage of the actuator in order to reduce the forces that may be considerable during flight operations act on the Finn to support.
- An electronic control unit can be present in the missile fin deployment device. The electronic control unit can then have control logic which controls the pivoting mechanism and / or the twisting mechanism (in particular independently of one another). In this case, the control can consist in the control of a drive unit designed as an electric motor. If an actuator with a spring device is used, the control can also consist in unlocking a locking device, which then releases the energy store provided by the pretensioned spring device.
- control logic controls the
- Pivoting mechanism and the twisting mechanism in such a way that for an activation of the fin initially only the pivoting mechanism is actuated until the fin is pivoted out, so that the longitudinal axis of the fin extends radially to the missile. Subsequently, only the twisting mechanism is actuated to twist the fin. The rotation thus takes place separately in time and after the pivoting.
- the control logic can process operating parameters during flight operations. These operating parameters can relate to the flow conditions of the missile, the speed of the missile, the orientation of the missile in relation to the flow, the flight phase, the flight altitude and the like.
- the control logic controls the twisting mechanism during flight operations in such a way that the fin is rotated as a function of the operating variables.
- the fin can assume a basic position with a predetermined angle of attack and, compared to this basic position, a control can take place by changing the angle of attack in order to bring about or restore desired aerodynamic conditions and to influence flight operations.
- activation takes place in such a way that the fin is rotated by a maximum of plus / minus 20 degrees, a maximum of plus / minus 15 degrees or a maximum of plus / minus 10 degrees compared to a basic position, depending on the operating parameters.
- a position of the fin in particular the pivoted-in position of the pivoting mechanism of the fin and / or a pivoted-out position of the pivoting mechanism of the fin, can be secured by means of a latching or locking device.
- a latching or locking device or a common latching or locking device can secure the pivoting position of the pivoting mechanism and / or the rotational position of the twisting mechanism.
- a locking device is preferably locked and / or unlocked via an actuator.
- the same can apply to a locking device.

- the actuating element can, for example, be designed as a pull-and-push rod, a kind of connecting rod or a pendulum support, one end area of the actuation element being articulated on the swivel actuator, while the other end area of the actuation element is articulated (directly or indirectly) on the fin can.

- the fin 1 is in the folded-in and swiveled-in state according to FIG. 2 and the pivoting mechanism 10 is in the operating position according to FIG. 5.
- the swivel actuator 21 is first actuated, whereby the end area of the fin 1 is pulled into the through recess 13 via the actuating element 37 and the swiveling 5 of the fin 1 follows is brought about externally.
- the end region of the fin 1 sits firmly in the holding recess 36, so that the support and / or holding device 22 becomes effective.
- the fin 1 is thus in the operating position according to FIG. 3 and the pivoting mechanism 10 is in the operating position shown in FIG. 7.
- a rotation 4 of the rotation mechanism 24 and thus the fin 1 can also take place during flight operation by driving the rotary actuator 29 in both directions by any angle.
- the fin 1 it is possible for the fin 1 to be rotated in both directions and / or the fin 1 to pivot in and / or out during flight operation by means of the actuators 21, 29. Preferably, however, the fin 1 is merely pivoted out and the fin 1 rotated during flight operations, without the fin 1 having to be pivoted back towards the missile 6.
- the fin 1 takes place by a pivot angle of 90 °. This is not necessarily the case. Smaller or larger swivel angles are also possible.
- the longitudinal axis 2 of the fin 1 in the pivoted-in state does not extend parallel to the longitudinal axis 9 of the missile 6, but rather forms an acute angle with respect to it.
- the longitudinal axis 2 of the fin 1 does not extend normal to the lateral surface of the missile 6 in the swiveled-out state, but forms an acute angle to the surface normal of the missile 6, whereby the fin 1 can be inclined forwards or backwards.
- transverse axis 3 of the fin 1 is not oriented tangentially to the outer surface of the missile 6 in the pivoted-in state, but rather relative to the outer surface is inclined. It is also possible that, in the unfolded basic position of the fin 1, the fin 1 is already positioned with a small angle of rotation with respect to the oncoming flow.
- the pivoting mechanism 10 and the rotating mechanism 24 together form an actuating mechanism 31.
- the missile-fin deployment device 7 is held on the missile 6 via a missile holding area 32.
- the missile holding area 32 can be formed by bearing surfaces of the at least one pivot bearing 25 and / or of the axial bearing 26 as well as the supports of the actuators 21, 29. It is also possible, however, for the missile fin deployment device 7 to have a housing in which the rotary bearings 25 and the axial bearing 26 are then arranged and the actuators 21, 29 are also arranged. The housing then forms the missile holding area 32, in which case the missile fin deployment device 7 can be screwed to the missile 6 via the missile holding area 32 or can be fastened to it in some other way.
