Definitions
- the invention relates to a projectile with fold away from the projectile fuselage Wings according to the preamble of claim 1.
- Such a projectile is known from DE 33 40 501 C2.
- this known projectile has the aerodynamically profiled front spar of respective wing a relatively large width. Tread depth on, so in the Projectile hull a correspondingly large receiving space for the respective Wing must be provided.
- the rear spar can be at this known Projectile designed as an aerodynamically profiled rigid body or of be formed a tension cable.
- the guy rope is with his first End portion connected to the outer end of the front spar such that on the front spar in the folded away from the projectile fuselage state of Wing flexing is effective.
- the front spar is the front spar with a correspondingly large tread depth dimensioned.
- DE 34 03 573 A1 which is an additional patent application for The above-mentioned DE 33 40 501 C2, is a projectile of the Projectile fuselage known as foldable wings, with the respective wing has a front spar with a relatively large tread depth and the rear spar may be formed by a rigid body or a tension cable. Also in this known projectile, the first end portion of the Schuholms with the outer end of the front spar connected in such a way that from the projectile fuselage folded state of the wing on the front spar one Bending stress becomes effective when the rear spar of a tensioning cable is formed.
- DE 35 23 769 A1 discloses a submunition missile with adjustable sliding wings, wherein the respective sliding wing a front spar relatively large tread depth and a rear spar, the one of a rigid Body or can be formed by a tension cable. Also with this known missile is the rear spar forming tension cable with his first end portion connected to the outer end of the front spar such in the unfolded state of the wing of the front spar on bend is claimed.
- a wing housing for a missile with a Self-righting wing assembly with elements known, each one Chamber, which has a self-righting wing in the folded state picks up, and form an opening through which the wing is erected extends, with a ejectable lid, the detachable above the opening is appropriate.
- the wing housing has a base plate, which as Storage element for struts of the wing and for clamping a Cloth covering of the wing on the wing housing is used.
- the cloth covering the wing surrounds the struts and has an apron, which between the Base plate and a circumferential clamping strip of the wing housing is clamped.
- the invention is based on the object, a projectile of the beginning mentioned type with small-packing wings to create the high Have lift coefficients.
- the tensioning cable with its first end portion with the outer end of the front spar in the direction of the front spar, with this at least approximately aligned, connected, and the tensioning cable with his second end portion to a provided in the projectile fuselage Clamping device is connected, so that the tensioning cable and the Covered in the unfolded state of the wing between the unfolded fixed front spar and formed by the tensioned tension rope Rear spar are permanently stretched, the front spar is unfolded Condition not or only negligible on bending but only on Pressure claimed, which is why the front spar with a relatively small tread depth may be formed, resulting in the advantage that the respective wing is small packed, i. in the folded state, only a small receptacle or storage space needed.
- the tensioning device for the tensioning cable can be formed by a spring element be. Likewise, it is possible that the tensioning device for the tensioning cable a pyrotechnic element or a piston-cylinder unit.
- the tread depth of the front spar decrease from its inner end to its outer end. This decrease can be continuous, but it is advantageous if the tread depth of Vorderholms from its inner end to its outer end in sections Gradually decreases, because such a trained front spar easy is feasible.
- the covering a concave Has curved rear edge, in the unfolded state of the wing is stretched by the permanently tensioned tension rope, so that a Fluttering movement of the covering is prevented.
- the rear edge of the Covering is concavely curved in such a way that this against the concave curved rear edge forced tensioned tension cable with its first End portion with the outer end of the front spar at least approximately is aligned to a bending stress of the front spar of the to avoid unfolded wing.
- the fabric is double-layered, wherein the Front spar and the tensioning cable between the two layers of the clothing are provided.
- the covering of the respective wing with its root edge attached to the projectile fuselage it is preferred if the Root edge of the fabric is slightly concave, in order from the Projectile fuselage folded flight condition of the wing the stringing to tighten all sides in such a way that the desired high lift coefficient is achieved becomes.
- root edge of the two-ply fabric each with a Umschlagrand is formed by the two root edge channels for Root rods are formed, extending along the projectile trunk extend.
- the projectile according to the invention has the advantages that the Volume requirement for the respective wing in the folded state is low, that the bending stress of the front spar of the respective, from the projectile hull folded wing is very small or negligible small that the wing covering over all its edges, i. through the front edge the front spar, over the rear edge by the concave rear spar forming tension rope and along the root edge by the slight concave trained root edge of the clothing is tensionable, that of the Projectile fuselage folded wings have a high buoyancy coefficient, and that the respective wing consists of a few individual parts, so that the Production costs are correspondingly low.
- FIG. 1 shows a section of a projectile 10 in a sectional view with folding away from the projectile fuselage 12 wings 14, of which in FIG 1 is shown only one folded away from the projectile fuselage 12 state.
- the wing 14 has a front rail 16, the inner end 18 to a Axis 20 from a space-saving folded position in the in Figure 1 drawn unfolded flight position is adjustable. In the unfolded Flight position is the front spar 16 by means of a suitable device from Projectile fuselage 12 fixed away.
- the rear spar 22 of the wing 14 is formed by a tensioning cable 24, which with its first end portion 26 with the outer end 28 of the front spar 16 and that with its second end portion 30 with a in the projectile fuselage 12th provided clamping device 32 is connected.
- the tensioning cable 24 is with its first end portion 26 with the outer end 28 of the front spar 16 in Direction of the front spar 16 - with this at least approximately aligned - connected so that the tensioned by means of the clamping device 32 tensioning cable 24 in the unfolded state of the wing 14 in the front spar 16 no or only a negligible bending load but only a compressive load initiates. Therefore, it is possible, the aerodynamically profiled front spar 16 relative narrow, i. with a relatively small tread depth, form.
- the profile depth of the Vorderholmes 16 increases from the inner end 18 to the outer end 28 graduated in sections. These sections are identified by the reference numbers 34, Designated 36 and 38.
- the Covering 40 is formed in two layers.
- the two layers 42 and 44 are along the leading edge 46 of the fabric 40 with each centrein Published.
- the two layers 42 and 44 of the fabric 40 have a concavely curved trailing edge 48.
- Parallel to the rear edge 48 runs in Immediate neighborhood of the same a hem seam 50. At this seam seam 50 comes the tension cable 24 closely to the system when the wing 15 in the in Figure 1 drawn unfolded flight position is.
- Each of the two layers 42 and 44 of the fabric 40 has a the Projectile fuselage 12 facing root edge 52 on. As shown in FIG. 4 can be seen, the root edge 52 of each layer 42, 44 a Umzzirand 54 on. The Umschlagr selected 54 of the two layers 42, 44 of the fabric 40th are turned away from each other. Each envelope flap 54 is associated with the one Layer 42 and 44 connected by a hem seam 56, so that two Root canals 58 for bullet-proof root bars 60 (see also FIG. 1) result. The root bars 60 extend along the projectile trunk 12 of the projectile 10.
- the root canals 58 are back completed by a closing seam 62, which extends along the two Envelope 54 extends and the hem seam 50 crosses.
