DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a lightweight, shoulder-fired, flat-trajectory, disposable weapon system. In particular, this invention relates to a disposable weapon system for shooting multiple ammunition rounds from a stick magazine capable of penetrating armor personnel carriers (APC), wherein the weapon system is designed to minimize weight, cost, and maximize safety.
2. Background Art
Military operations have demonstrated the need for a weapon, to be used by infantry troops, capable of incapacitating armored vehicles This task however, has proven to be difficult. The weapons currently available to infantry forces lack the capability to damage such vehicles.
To illustrate the difficulty in destroying armored vehicles, an example is helpful. Some APCs are constructed of approximately two inches of rolled homogenous armor (RHA) and are capable of traveling at speeds of approximately 35 miles per hour. These two factors, coupled with the distance that a soldier is positioned away from the vehicle when firing his weapon, make the APC almost immune from small platoon attacks
Some weapons do exist that are capable of penetrating the two inches of metal shielding an APC. However, many of these weapons lack a flat-trajectory projectile path, thus making the likelihood of hitting the target extremely small. In other words, a remote probability exists that a weapon will hit a target moving up to 35 miles per hour at a distance of over 200 meters using a "lob" trajectory path
Additionally, the existing weapon systems with the same capabilities as the present invention are fired "over the shoulder" or from a platform. One reason for this type of firing method is that the weapons are bulky and heavy, which also negates the feasibility of use by infantry force. Also, these weapons are fired from a position other than against a soldier's shoulder because the resulting back-blast could injure the weapon user. Futhermore, this back-blast make firing these weapons impracticable in closed spaces and extremely dangerous to fire forward of other soldiers or supplies.
The existing weapons are also expensive. The weapons are designed to withstand a large number of firings, possibly 10,000 rounds or more. The materials, therefore, must be manufactured to endure the peak stress and the average stresses of every firing withstand the cyclic loading for each firing. As a result, the engineering design not only increases the cost of these weapons but also creates an unwieldy weapon for infantry troops.
SUMMARY OF THE INVENTION
The presently preferred embodiment of the disposable weapon system comprises at least one ammunition round having a casing which can withstand the firing forces of the ammunition round, a means to fire the ammunition round, a stick magazine and a barrel that aligns with the ammunition round in the magazine through which the projectile travels.
Unlike other armor penetrating weapons, the present invention is fired the same as a conventional rifle. The characteristics that make the weapon system of the present invention similar to a rifle are its shoulder-fired and flat-trajectory aspects. In contrast, the present invention is different from a rifle because it is disposable and designed to minimize weight.
One object of the weapon system of the present invention is that it is shoulder-fired instead of fired "over the shoulders" or from a platform. This difference from the prior art affords the present invention with many advantages. First, the accuracy of the weapon increases. This accuracy improves because the flat-trajectory projectile path and the ease of aiming a shoulder-fired weapon. Next, the safety increases for the weapon user and for others in his vicinity because the weapon system of the present invention contains the firing exhaust instead of having a back-blast.
In addition to being shoulder-fired, another objective of the present invention may be the capability to pierce armor vehicles. The preferred embodiment provides a weapon system that is
