Definitions
- the invention relates to a missile with a wing consisting of several wings Tail unit, the wings each about a bearing axis from a folded rest position are pivotally arranged in an outwardly folded flight position, according to Preamble of claim 1.
- Such missiles with a foldable stabilization stabilizer which during their flight, e.g. due to their wing position in relation to the missile axis, a rotating movement Execute (compensation twist) are known. To a defined position of the wing To get throughout the trajectory, they are in known missiles in locked outward end position locked by a locking device.
- a disadvantage of these known missiles is, inter alia, that during flight forces acting on the wing cause changing mechanical loads on the wing locks to lead. These changing mechanical loads result then often vibrations of the entire missile, which e.g. when using Structure-borne noise sensors for misbehavior of the detonators, such as explosives, being able to lead.
- the invention has for its object a missile of the type mentioned specify the wing in the unfolded state as aerodynamically favorable as possible Assume position without the forces acting on them (air attack forces, centrifugal force, Mass inertia of the wings) lead to vibrations of the missile.
- the invention is essentially based on the idea of the wings of the missile not to be locked in a certain flight position folded outwards.
- the air attack forces are usually greater than the inertial forces, but with the onset of twist and the associated centrifugal forces Torques generated, which also pivot the wing around the bearing axes effect forward.
- the centrifugal force increases during the flight of the missile constantly increasing, but their axial component increases more and more with the folding back of the wing from. This leads to a torque equilibrium, which is usually at Angle of attack of the wing ⁇ is> 90 °.
- 1 denotes the rear area of a missile with an empennage 2.
- the tail unit 2 comprises a plurality of wings 3, 4, the front edges of which are known per se Are sharpened so that the missile 1 during its flight Longitudinal axis 5 rotates.
- the wings 3, 4 are each about a bearing axis 6 from a folded rest position (see dashed line of wing 3) can be pivoted into an outwardly folded flight position.
- the wings are laterally offset with respect to the respective bearing axis 6, so that after reaching a maximum angle of attack ⁇ m of e.g. 120 ° with their underside 10 strike the rear area 11 of the missile.
- ⁇ m e.g. 120 ° with their underside 10
- the respective wing 3, 4 When the missile continues to fly, the respective wing 3, 4 is then in a forward end position pivoted back out of balance on it during flight acting forces results.
- the air attack forces 7 press the respective wing 3, 4 to the rear, while the inertial forces 8 and the centrifugal forces 9 pivot the wings 3, 4 cause forward.
- the angle of attack a is e.g. 105 °.
- the stop which is the pivoting of the wing limited in its outward folded flight position, also by separate on the rear Part of the floor arranged stop elements can be realized.
- the maximum Angle of attack can also have a value greater or less than 120 °. Indeed the angle must be greater than that which arises during flight and the aerodynamic Angle of attack characterizing the position of equilibrium.
