Abstract: Disclosed is an explosive reactive armor with a momentum transfer mechanism by developing a new protection mechanism in which a momentum transfer mechanism by detonation of a reactive material is integrated with a thickness increase mechanism. In this explosive reactive armor with the momentum transfer mechanism, a flying element always travels with a vertical angle or a slant angle with respect to an ongoing direction of the threat such that a momentum of the flying element is transferred to the threat effectively. As a result of this, shear force is induced over an entire length of the threat and thus the threat can be destroyed. Therefore, a protection effect can always be achieved regardless of an impact angle of the threat. Also, a protection capability can be achieved even in case of a vertical impact which is the most vulnerable case for the existing explosive reactive armor.

The result is lightweight, composite hybrid structures for ballistic protection particularly suited to tactical ground vehicles. The preferred embodiment is a combination of three major components: 1) an optimally designed web system that allows armor tiles to be attached to it and that can be easily integrated with existing vehicle structures; 2) an advanced composite armor unit using a patent-pending BTR (Bio-mimetic Tendon-Reinforced) material as the supporting structure; and 3) optimally placed “waiting materials” which can provide enhanced ballistic impact resistance, energy absorption capability and structural integrity. These “waiting materials” are structural members that are not active at the beginning of the ballistic impact, but become active when needed or the active members have failed.

Abstract: The Highly Survivable Urban Utility Vehicle (HSUUV) provides a novel way to balance the concerns of armor, mobility and cost. Prior art distributes armor to protect all areas of the vehicle evenly, thereby distributing the maximum armor weight capacity evenly. The HSUUV provides armored protection in levels, which vary depending on the location of the armor and that location's ballistic threat. Entrance to the HSUUV is located in location(s) other than the traditional side door(s) so as to provide additional armored protection in the area receiving the greatest ballistic threat. Using the HSUUV, soldiers can safely and quickly enter areas that they otherwise would have had to fight and sustain casualties to enter. The vehicle will give United States forces an unprecedented amount of flexibility, allowing for better strategic and tactical decisions.
