DE2700132A1 - Protection against ballistic missiles for military equipment - has active armour with rotating plates absorbing missile kinetic energy - Google Patents

Abstract

The protection arrangement against ballistic missiles utilises energy of rotating rigid bodies. This rotating element can be made from armoured steel and is used preferably for protection of military equipment. The armour consists of rigid bodies such as round plates which rotate at high speeds. A projectile meeting such a disc acts as shear pin and it must stop the whole rotating mass in order to ensure penetration. The kinetic energy of projectile is balanced by the kinetic energy of the disc. The rotating movement of the armouring induces the projectile to penetrate more material than that provided by the thickness of the armouring. The protection can be further increased by increasing the rotating speed without increasing the weight.

Description

Appendix to the patent application from the engineer Ulrich Heym Description of the invention with the technical name: U netic armor The invention protects objects of all kinds against approaching destructive agents of any kind Nature. The preferred area of application is the protection of military equipment and important assets.

Better protection of facilities and military equipment increases them Effectiveness and increases the deterrent effect.

Armor used so far to protect against the effects of weapons are passive and only use a very small part of the Armor hit by the projectile.

Through special material or structural design such as angled Areas and bulkhead arrangement was tried to secure every point on the object To make fire. The development of weapons and ammunition with ever higher penetration rates caused that adequate armor protection became impossible and one therefore had to rely on one Armor almost completely dispensed with (e.g. surface ships) or the usable space E.g. in a tank it got smaller and smaller because the outer walls were as flat as possible Had to get angles. The weight of the thick armor also inhibits the mobility of military equipment.

It is true that they are rotating devices for deflecting enemy projectiles known, but they only use relatively small masses as impact bodies and can Due to the elasticities inherent in the system, bullets cannot slip through impede.

In addition, they only have an effect on projectiles that fly relatively slowly.

The invention is based on the object of providing active armor sheep that provide effective protection with a reasonable weight and high interior space utilization results.

The object is achieved in that the armor consists of rigid bodies (e.g. disks) that rotate at high speed. A striking one Projectile acts like a locking pin and has to stop the entire rotating water, if it wants to break through. The kinetic energy of the projectile is thereby of compensated for the kinetic energy of the disc. To protect the little ones from the Projectile acted upon zone so the entire body of revolution is used. One Another effect results from the fact that the rotating movement of the armor causes the The projectile has to penetrate much more material than the armored car.

thickness is given. A vertically rotating disc has alone because of this the effect of an armor plate with a very shallow angle.

If, for example, the armor is to be transparent in front of the viewing openings, then so At this point, a solid of revolution with holes, breakouts or propeller shape is created used, which becomes transparent at high speed. The hole diameter or the The distance between the propeller blades is smallest at the pivot point and can be turned towards the outside be enlarged. It is calculated using the following formula: d = (2 x floor length x target speed / bullet speed f caliber. When the target speed starts the maximum permissible hole diameter results from any radius this radius for the projectile under consideration. The holes need to be evenly spaced that there is no streaking when turning.

Perforated disks also cause projectiles to be broken up.

The rotating bodies only need to be activated in the event of danger and therefore constantly consume energy. A low drive power is sufficient because a certain period of time is available for the build-up of energy. The saved Energy can e.g.

used to drive or rotate the tower in the event of a motor failure will.

The achievable with the invention are that a Reinforcement of armor protection can be done by increasing the speed without the weight of the armor increases.

Devices and systems that have not yet been protected due to weight reasons can now receive effective protection. Heavy armored Devices can be lighter or, with the same weight, better armor protection obtain.

Bin exemplary embodiment of the invention is shown in the drawing and is described in more detail below.

Figure 1 shows the conception of a small armored bicycle ".

added Figure 2 shows the vehicle from the front and Figure 3 from the rear.

The armor consists of rotating armored steel disks. Spherical apertures in the hollow shafts of the discs 1 and 2 enable lateral weapon action. the Disk 3 protects the tires and is driven directly by the drive shafts. The reduction for the wheel speed is done by a planetary set in the wheel hub. Panes 4 and 5 protect the driver's door. The disc 5 has bores and enables the driver to see from the side under armor protection.

The disks 6 - 8 allow the view through their holes front under armor protection and the disk9 to the rear. In the disc 7 are the Holes sealed with transparent synthetic resin so that the vehicle can wade deep can be sealed. The center of the discs has an outward point to deflect projectiles. At this point there is also a spherical diaphragm on disk 9 and enables weapon action to the rear. The discs are driven, for example via DC shunt motors, which act as generators if the motor fails work and a high-speed starter takes the vehicle out of a danger zone can move away.

The supporting frame for the kinetic armored washers contains ring profiles, which frame the panes and brake them through friction if they are damaged.
