As Hypersonic weapons enter the US arsenal there is a need for cost control and high rate of production which is currently not being met by the current state of the art material systems, like Carbon-Carbon. What is needed is a Thermal Protection System (TPS) for aero structures that can survive the Hypersonic environments of high heat in oxygenated environments. A means to do this is using Peregr ...

Navigation and communication systems have traditionally been developed separately resulting in the use of redundant hardware on the same platform for different purposes. In addition, authentication has generally been an afterthought, added on only after t

High temperature jet plumes emanating from aircraft engines and missiles produce effects that are of interest for threat detection, environmental noise, and engine development purposes. Optical and infrared emissions from plumes are sources of light and heat signatures, respectively, that can potentially be used for tracking or targeting vehicles in flight.  Acoustic noise from jet plumes can pot ...

Conventional “subtractive” machining is a huge industry with critical implications for USAF and DOD. The vast majority of safety-critical parts are manufactured using subtractive machining because it produces excellent dimensional tolerance and a high-qua

Virtual EM proposes develop a massively parallel ASIC for orders of mangnitude speed up of electromagnetic simulations of thin optical lenses made of metamaterials. The ASIC will implement a prorietary algorithm and will deliver scalable run-times that cut the simulation time by more than 1000x compared to today's state-of-the-art simulators.

The existing HFBL (High-Frequency Bottom Loss) database has been recognized to be unsatisfactory due to its lack of physical underpinning and inability to provide consistent performance across frequency and space. The aim of the project is to replace the HFBL database with a geoacoustic model that leads to a smooth transition to the LFBL (Low-Frequency Bottom Loss) model at 1 kHz. To this end, thi ...

Development of hypersonic aircraft and weapon systems has become a critical focus for the Department of Defense to maintain global strike and projection of force capabilities. Despite decades of research, traditional computational fluid dynamics (CFD) methods are either incapable of adequately predicting complex features in hypersonic flows or too expensive to be of practical use for vehicle desig ...

This overall research program is oriented towards a deeper experimental and theoretical understanding of meteorological properties of the marine wave boundary layer (MWBL) and laser light propagation in the marine environment. The main objective is to develop a periscope imaging, electronic warfare, and High Energy Laser (HEL) beam propagation model over the marine aerosol boundary layer for the i ...

High power electronics are being increasingly limited by conventional single-phase thermal management technologies. Refrigerant two-phase cooling presents a significant opportunity for thermal management of high-power electronics. While recent advances in cold plates and evaporators have been demonstrated in high heat flux applications, the condenser-side of the two-phase coolant loop has not kept ...

Thermal management using two-phase cooling systems offers significant advantages in terms of size, weight, and power reduction. These size reductions are mainly attributable to the evaporation part of the process, where heat transfer coefficients can be as high as 100 kW m-2 K-1. This is not the case for condensation, which can typically transfer lower heat fluxes at the same temperature differenc ...
