ABSTRACT: The sensor system requirements for image based navigation that uses passive millimeter wave imaging radiometry will be established based on existing RelNav and AbsNav algorithms that were demonstrated to work in multi-modal imagery. Existing flight data will be used to simulate the PMMW imagery for these tests. A preliminary design of such a PMMW system will be created. Under Phase-II th ...

ABSTRACT: The overall objective of this project is to develop scalable simulation components that effectively model the meso-scale physics of heterogeneous energetic materials subject to dynamic shock loading including matrix debonding, void collapse, and damage due to crystal to crystal interactions, and bridges the meso-scale to the macro-scale for system scale simulations of the transition to d ...

ABSTRACT: The objective of this proposal is to demonstrate the feasibility of a flexible, low-cost, integrated and sensitive broad spectrum optical property characterization system. We propose a hyperspectral imager designed for operation in the 300nm 2000nm spectral region with state-of-the-art spectral and spatial resolution through the use of a high density array of high finesse (F = 1000) tuna ...

ABSTRACT: A platform (PHA-fuse) for the stabilization of diagnostic and therapeutic reagents will be established based upon the polymer, polyhydroxyalkanoate (PHA). Fusions of a target molecule to PHA synthase, the enzyme responsible for PHA synthesis, will be constructed and used to catalyze the synthesis of PHA granules. These PHA granules will help stabilize the fused target molecules and elimi ...

ABSTRACT: Active control of the shock system in a scramjet engine isolator opens possibilities for enhanced engine performance and reduced engine weight by eliminating excess isolator design margin. A successful system will allow for maximum performance from a given engine configuration and will deliver range and efficiency that exceeds those possible using passive unstart control. Our approach is ...

ABSTRACT: Hypersonic vehicles will require structures that can withstand highly transient flows and complex loadings throughout the flight trajectory. Shock boundary-layer interaction can excite panels locally and lead to structural failures. Non-contacting measurement technologies are needed to characterize the effect of flow transients (due to pressure and temperature fluctuations) on the struct ...

ABSTRACT: Exquadrum, Inc. proposes to develop an innovative multi-mode power generation system for hypersonic flight vehicles. This system produces the required power output that the flight vehicle demands, independent of the flight characteristics at the time. However, this system will work in conjunction with the propulsion system to augment the power generation capabilities. This is accomplishe ...

ABSTRACT: An unseeded measurement technique is proposed for simultaneous spatially-resolved measurements of density, temperature, and velocity in hypersonic wind tunnel flows with the future potential for time-resolved measurement capability. A variant of filtered Rayleigh scattering (FRS) will be developed that takes advantage of unique monotonic relationships between molecular vapor cell filter ...

ABSTRACT: Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal cracking of hydrocarbon fuels is always accompanied by coke formation. The coke deposits on the combustor and nozzle walls reduces heat fluxes and c ...

ABSTRACT: Future corrosion and wear protection of structural metals on on military aircraft and weapon systems will require advanced development of metallic and composite materials that are not restricted with respect to environment, safety and occupational health regulations. Conventional metallic alloys containing chromium, nickel, cobalt, and tungsten that have historically provided coating pro ...
