Definitions
- the invention relates to a tail unit with deployable wings for projectiles and missiles.
- This tail preferably comprises a wing element made of flexible cloth material, which is double-walled and by means of a plurality, for. T. telescopic struts comprising holding device can be folded out.
- the holding device consists of a large number of parts, which are relatively large within the missile
- the invention has for its object to provide a tail unit with deployable wings, which is made up of significantly fewer parts and is therefore cheaper to manufacture and takes up only a small space in the volume of the projectile or missile, but which is also robustly constructed and thus also the highest acceleration loads withstands when shooting projectiles.
- This object is achieved by the invention specified in claim 1.
- Advantageous embodiments of the invention emerge from the subclaims.
- FIG. 1 a cross section through part of the missile according to FIG. 2 with a view of the side edges of a flying wing;
- FIG. 3 shows a cross section through the missile in the area of the tail unit with the wings folded in
- Pig 4 a detailed representation of a wing with a viewing direction according to arrow 3 from FIG. 1;
- FIG. 2 shows, in a schematic, perspective representation, a missile 10 with a tail unit comprising deployable wings 11 arranged in the aft region.
- Missiles of this type and projectiles are fired from launchers or from large-caliber barrel weapons and are intended to reach point targets from as far away as possible with the greatest possible precision.
- a stabilizer is required for trajectory stabilization and / or final phase steering, which should have optimal aerodynamic properties, but which is robust and space-saving, in order to withstand high acceleration stresses that occur in particular when firing from guns, and on the other hand as little as possible that intended for payloads To claim the volume of the missile / projectile.
- FIG. 1 shows an enlarged cross section through part of the missile 10 according to FIG. 2 with a view of the side edges of a wing 11 of the tail unit.
- the wing 11 consists of two wing blades, 12, 12a, which are connected to one another on the tip side, for example riveted, and which are attached on the root side to separate bearings 17, 17a which can be changed in terms of their circumferential spacing in such a way that the wing blades 12, 12a in the unfolded state of the Wing 11, which is shown in Fig. 1, are set up like a roof.
- the blades 12, 12a themselves are made of an elastic and flexible material, such as. B.
- FIG. 1 One of the bearings 17, 17a is an articulated fixed bearing 17a, while the other bearing is an articulated sliding guide 1 ager.
- the exact structure of these bearings will be explained later with reference to other figures of the drawing (Fig. 4, Fig. 5). This bearing arrangement enables - as can be seen in detail from FIG.
- the wing blades 12, 12a are wrapped in the circumferential direction around the tail part of the missile 10.
- This principle is known from conventional winding tail units. However, these are only connected linearly to the outer surface of a projectile or missile and therefore do not have the stability required for precision approaches when expanded.
- the wing blades 12, 12a of each wing 11 lie closely adjacent to one another, which is achieved in that the sliding guide bearing 17 is arranged in parallel directly next to the articulated fixed bearing 17a of each wing 11.
- the wings 11, seen in the radial direction can also be carried out for a comparatively long time and thus with regard to the aerodynamic requirements, since even these long wings can be accommodated in a space-saving manner.
- the wing blades of a wing 11 cover at least the bearing area of an adjacent wing. 1
- the bearings 17, 17a of the wing blades 12, 12a are spaced apart from one another in the circumferential direction, so that the roof-shaped arrangement of the wing blades 13, 13a shown results.
- the wing blades 13, 13a reach this position in that the articulated sliding guide bearing 17 is removed from the fixed bearing 17a in the circumferential direction when the wing 11 is unfolded.
- Fig. 4 shows a view of a part of the wing blade 12a and the shell 16 of the missile 10 with a view from the direction of arrow 4 according to Fig. 1.
- Fig. 4 only details of the articulated sliding guide 17 are shown, while the articulated Fixed bearing 17a, to which the other blade 12 is attached, is not visible.
- 5, on the other hand shows a section through the wing 11, along the line 5 - 5 according to FIG. 1 with a view of parts of the casing 16 of the missile 10.
- the articulated fixed bearing 17a can also still be seen.
- Each bearing 17, 17a comprises a hinge part 13, 13a, which is rotatably mounted around a pin 31, 31a, 31b, which is fixedly arranged in the jacket 16 of the missile 10 and is slidably mounted.
- Each of the pins 31 consists of at least two parts 31a, 31b in order to facilitate the assembly of the wing blade 12, 12a.
- the wing leaves 12, 12a are fastened in the hinge parts 13, 13a, riveting or gluing preferably being offered for the fastening.
- the slidably mounted pin 31 of the articulated slide guide bearing 17 (FIG. 4) can slide in parallel slideways 15 between two end positions. In the first end position - in this case, the vanes 11 are folded in according to FIG.
- the pins 31 of both bearings 17, 17a are arranged immediately adjacent to one another.
- the pin 31 of the sliding guide bearing 17 is max. arranged away from the pin 31 of the articulated fixed bearing 17a, which corresponds to the unfolded state of the wing 11 according to FIG. 1.
- the wing blades 12, 12a are expediently curved in the direction of their longitudinal extent, so that they practically form part of a cylinder jacket.
- This curvature can the wing blades 12, 12a made of an elastic material by known manufacturing processes, such as. B. rollers are impressed.
- the expedient curvature of the wing leaves 12, 12a can also be brought about in that the hinge parts 13, 13a for fastening the wing leaves 12, 12a have a clamping slot which, in accordance with the desired curvature, has an arcuate shape.
- the curvature of the wing blades 12, 12a is temporarily pressed flat, so that the wing blades 12, 12a come to lie closely one above the other in a space-saving manner.
- the wing blades 12, 12a tend to take up the embossed curvature again, so that the unfolding process is thereby promoted.
- This curvature gives the blades 12, 12a excellent resistance to buckling under pressure and thus ensures the advantageous aerodynamic properties of the tail unit.
- a second curvature is also impressed on the wing blades 12, 12a, for example by rolling, which likewise promotes their unfolding and their stability in the unfolded state.
- This curvature also contributes to the fact that the wing blades 12, 12a are still biased in the unfolded state such that the slidably mounted pins 31, 31a, 31b are resiliently pressed into their end position and held there.
- the hinge part 13 of the fixed bearing 17a does not run over the entire width of the wing blade 12, but leaves space on both sides for the two partial hinges of the articulated sliding guide bearing 17 lying in axial alignment when folded Folding of the wing 11 does not impede the wing blades 12, 12a in the area of the hinge parts 13, 13a
- the wing blade 12a connected to the sliding guide bearing 17 contains a window-shaped recess in the middle, while the wing blade 12 connected to the articulated fixed bearing 17 has recesses in the side area of the bearing point.
- the missile 10 rotates about its longitudinal axis, that is to say has a swirl.
- This swirl can be imparted to the missile 10 in a simple manner in that at least one of the wing blades 12, 12a of the wing 11 is turned or twisted with respect to the longitudinal axis of the missile 10.
- This employment is expediently achieved in that the slideways 15 are of different lengths, so that the locking pins 32 engage at different distances from the pin 31 and thereby twist the wing blade connected to them.
