Description

UNMANNED FLYING APPARATUS The invention relates to an unmanned flying apparatus for attacking ground targets according to the preamble of claim 1.

A flying body such as a drone for attacking ground targets from the ground is known from DE-PS 29 04 749. For attacking a radar position of the enemy, the drone is equipped, inter alia, with a target seeking head and a detonable warhead. After locating the target the drone attacks the same by diving and impact.

The chances for success are relatively low, as the drone may be located relatively early and be relatively vulnerable to anti-aircraft weapons associated with the target. Mobile target may also in principle evade the attack during the dive phase.

A drone with delta wings but without a warhead is known from DE-OS 32 40 903.

For attacking relatively heavily armoured targets such as tanks DE-PS 27 41 894 proposes a warhead with at least one spike forming hollow charge. This warhead forms a part of a projectile or a flying body. Spike forming hollow charges are almost ineffective from a relatively large target distance of approximately 100 m. In addition arrangements providing for an axle stable position of the warhead in a projectile or in a flying body are relatively expensive.

Therefore the invention has the object of inexpensively and effectively attacking lightly or heavily armoured targets by an unmanned flying appartus.

The invention reaches this object by the characterising features of claim 1.

The invention provides an inexpensive and'effective weapon system.

The stable approach flight of flying apparatus such as drones provides a weapon platform with the advantage of a sure detection of the target owing to the low speed of the drone of approximately 250 to 300 km/hour and an average attack flight height of approximately 70 m.

The attack on the target is by projectile forming charges, which may be, according to the features of the dependent claims, arranged stationary in the drone, or may be in form of ejectable sub-ammunitions.

In case a target lies in the direction of action of the stationary charge arrangement, they may be fired without a prior correction of the flight position.

In case the target lies outside the direction of action of the charge arrangement, a small correction of the flight position (such as a rolling movement) is sufficient to attack the target.

The effectiveness of the drone may be augmented by arranging the charges in the form of two or more axially parallel P-charges which are fired simultaneously. This provides for a higher probability of hitting and destroying the target, in particular of difficultly attackable targets such as tanks.

The effectiveness of the drone may be augmented by attacking a plurality of targets by a single drone, that is by providing the drone with at least one ejectable sub-ammunition unit. After the ejection of a sub-ammunition, the drone is stabilized for detecting additional targets and ejecting a further sub-ammunition, respectively firing of the stationary charges.

Relatively small corrections of the flight position are sufficient when the ejectable sub-ammunitions are arranged in the region of the center of gravity of the drone .

When the drone is flying very low a high probability of hitting the target may be achieved by ejecting the i ejectable sub-ammunition in the upward direction. This provides for a long time interval for stabilising the sub-ammunition with subsequent detection of the target in an enlarged detection radius and the release of the projectile forming charge, thereby providing for the - - desired hit probability.

For attacking the deployment area of armoured units o¾»~ unmanned flying vehicles, it is advantageous to have a plurality of drones overfly the target area in stripes. This is also a simple measure for largely preventing an attack of a plurality of drones on the same target.

It is important for the invention, that each of the projectile forming charges carried by the same flying craft should have a selectable mode of ejection from the carrier, that is either as a sub-ammunition unit or to be fired directly from the flying craft.

The selection of the mode of ejection encomprises also the possibility, in case there is a plurality of charges, also of combinations of modes of ejection, in which the charges may be ejected singly or in groups at time intervals or also all the charges may be ejected simultaneously .

Embodiments of the invention are illustrated in the drawings .

Fig. 1 represents a drone during the attack on a target .

Fig. 2 to Fig. 5 represents the arrangement of projectile forming charges in the drone of Fig. 1 , in different variants.

A drone 1 with delta wings 2,3, has body 4 subdivided into sections. In a nose section 5 there are, as may be seen from Figs. 2 to 5, projectile forming charges 35 in the form of static charges 6 to 8 and ejectable sub-ammunition units 9 to 11.

In an adjacent section 15 there is situated an arrangement for identifying a target corridor 16, this arrangement is not described. In a middle section 20 having a center of gravity 21, there is a sub-ammunition 9 ejectable upwardly.

In the aft section 25 there is a motor, not represented, for a propeller 26.

In the target corridor 16 a tank 30 is identified by the detection arrangement by corresponding target parameters .

The sub-ammunition 9 is ejected from a container 32 by an ejection charge 31 and stabilised by a parachute 33.

The sub-ammunition 9 is performing, as known per se, a revolving motion suspended on parachute 33. An independent detector arrangement ofthe sub-ammunition is firing, on locating a target, the projectile forming charge 35. An additional target 40, detected later, is attacked by projectile forming charge 10.

A third target 45 detected afterwards is attacked by the stationary projectile forming charge 6 in the drone. To make this possible, t&e drone is turned by the steering means of the same about the main axis 46 in the direction of arrow 47 until the target 45 is in the field of action of projectile forming charge:6. The trajectory of the projectile is indicated by the number 48.

According to Fig. 2, there are projectile forming charges 6 to 8 in the nose section 5. Between said charges 6 to 8 there are arranged isolating layers 51,52, reflective of shock waves. This provides for avoiding mutual influences disturbing the formation of the projectiles in cases of a simultaneous-firing of charges 6 to 8. In this case, it is intended to attack the. same target simultaneously by charges 6 to 8. The firing of the charges causes a destruction of nose section 5 with the crash of the drone as a consequence.

According to Fig. 3, there is provided, in addition to projectile forming charges 6, 7 and isolating layers 51, 52, also the sub-ammunition 9 ejectable downwards.

The lower side of drone 1 is designated by 53 and the upper side by 54.

According to Fig. 4, there are provided in the nose section 5, the stationary charges 6 and the sub-ammunition 10. In body section 4 there is, correspondingly to Fig. 1, the ejectable sub-ammunition 9, situated in the region of the center of gravity 21. 76632/2 The direction of action of charge 6 and sub-ammunitions 9 and 10 is indicated by arrows 42 and 41, respectively.

According to Fig. 5, the sub-ammunitions 9 to 11 ejectable downwards are arranged in the nose section 5 and body section 4 of drone 1.

With the arrangement according to Fig. 2 only one target may be attacked.

With the arrangement according to Fig. 3 two targets may be attacked, that is the first target with sub-ammunition 9 and the second one simultaneously with stationary charges 6 and 7.

With the arrangement according to Fig. 4, three targets may be attacked independently, the stationary charge 6 being intended for attacking the last target, the detonation of this charge causing a destruction of the drone.
