Current utilization of composite materials in air and surface weapons systems and structures is extensive, and the use of these materials can be expected to increase in the future. Weapons effectiveness assessments and the design of protective structures require methodologies to predict the terminal ballistic interactions between projectiles and fragments penetrating composite laminated target st ...

This project will analyze and select promising materials and designs to be used in the plumes of tactical solid rocket motors for missile steering and control. The emphasis is on high-performance refractory materials and compatibility of material systems. The control fins experience severe thermal and severe particulate erosion environments. Missile controllability requires fins with minimal er ...

This Phase I SBIR will develop a general purpose probabilistic finite element analysis system, ProFEA, that allows designers to perform probabilistic finite element analysis in a graphical environment that is completely familiar and similar to modern deterministic FEA. We have developed an innovative architecture that takes advantage of emerging file exchange and database standards (I ...

Recent efforts in the target vulnerability community (fixed ground targets, mobile ground targets, and aircraft) have focused on enhancing the blast and fragmentation modeling from weapon detonations. This includes modeling propagation of the detonation effects from the weapon through their interaction with the target geometry, to the development of loads on and response of the target structure. ...

Warhead design calculations and weapons effectiveness estimates require a methodology to predict structural response and the associated damage to air targets from reactive munitions. The objectives for the proposed Phase I study effort are to develop candidate launch conditioning, reaction initiation and reaction rate methodology, to incorporate existing ballistic, blast and quasi-static pres ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

The objective of this work is to develop analytical techniques to characterize wear and gouging phenomena of slippers at speeds up to hypersonic and demonstrate means to evaluate or reduce slipper wear/gouging. Specifically, we will develop analytical techniques that can be used to predict slipper wear patterns and gouging phenomena throughout the sled velocity regime to Mach 10. This will inclu ...
