The innovation is that of using blast-based concepts for the hypersonic/endo dispense of an array of small hardened projectiles (SHAPs) from an interceptor missile. Hit-to-kill successes using this SHAP concept will be significantly enhanced from that of conventional, single warhead concepts, akin to the improved probability of hitting a fast moving object with buckshot in comparison to a single ...

Intense dynamic and thermal loads will occur during stage-separation events that are of major concern from both operational and safety viewpoints. The insensitive-munitions (IM) stimuli and thermal/dynamic response associated with such events has received very little attention, yet this is of major concern for the KEI vehicle undergoing Stage 1 to Stage 2 separation. The KEI event is at lower alti ...

This proposal entails the development of specialized CFD models which can analyze transpiration cooling processes in complex high-speed environments. This is of significant importance to the Army since “well-designed” transpiration concepts are needed on missile systems that can provide reductions in both heat transfer and skin friction, resulting in improvements in overall performance. The ...

This program entails designing a Mach 10, scramjet propelled missile system using advanced CFD and design-optimization tools. The CFD codes were validated using full-scale data sets obtained from tests performed in the LENS shock tunnel facility. They contain advanced turbulence and thermochemical models. A preliminary rocket boosted and scramjet propelled concept vehicle will be designed meeting ...

Propulsion systems may perform a variety of maneuvers during the ascent phase of flight that can impact the performance of an interceptor or other parts of an MDA system designed to perform threat detection, discrimination, and tracking. Our Phase I effort focuses on building on extending existing plume signature software. A main technical objective is to establish the various components and app ...

A unified comprehensive framework that incorporates Maxwell’s equations coupled with the 3D unsteady Navier-Stokes equations of fluid mechanics, is being developed utilizing an innovative Multi-Physics Simulation (MPS) Architecture, for conducting multi-disciplinary simulations. The MPS Architecture can be used for analysis of problems where the dominant physical mechanisms are strongly influenc ...

The innovation proposed is the development of a high-fidelity software tool to be used for the design of hypersonic UAV dispense and subsequent dispense and dispersion of small hardened projectiles (SHAPs) from the UAVs using blast-based concepts. Such dispersed kinetic energy concepts can be effective against maneuverable and depressed trajectory threats for which conventional interceptors would ...

A joint analytical/experimental program to develop technologies to improve thermal output from combustors in propulsion systems while ensuring their stable operation is proposed. The program will exploit the use of energetic materials as secondary fuels to be injected suitably into the combustors to both increase their thermal output and ensure the mitigation of any instability that may arise in t ...

The F-22A main weapons bay experiences severe acoustic loading when exposed to the freestream. The severity and attenuation of this loading is exacerbated by the flight envelope of the F-22A aircraft, as well as the requirement to carry and release “smart” weapons throughout this envelope. This extremely harsh environment can also impact components that are mounted within the bay itself, inclu ...

Next generation liquid rocket systems envision novel designs for turbopumps that can operate at high suction speeds (i.e. low inlet pressures), and can be throttled over a wide range of low, off-design flow conditions. This is an extremely demanding flow regime where performance loss and damage from cavitation instabilities can be catastrophic since they can generate large amplitude pressure fluc ...
