SBC: EXQUADRUM INC Topic: AF15AT39
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 ...STTR Phase I 2015 Department of DefenseAir Force
SBC: Metrolaser, Inc. Topic: AF15AT38
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 ...STTR Phase I 2015 Department of DefenseAir Force
SBC: SOUTHWEST SCIENCES INC Topic: AF15AT38
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 ...STTR Phase I 2015 Department of DefenseAir Force
SBC: MZA ASSOCIATES CORP Topic: AF15AT40
ABSTRACT: MZA partnered with the University of Notre Dame proposes to extend MZAs WaveTrain wave-optics sensor simulation framework to model EO/IR sensors operating on hypersonic aircraft. Following the methods we have developed for aero-optical imaging through subsonic, transonic, and supersonic flows, existing WaveTrain libraries will be expanded to include hypersonic flow, shocks, thermal effec ...STTR Phase I 2015 Department of DefenseAir Force
Small Sample Size Semi-Supervised Feature Clustering for Detection and Classification of Objects and Activities in Still and Motion Multi-spectral ImaSBC: TOYON RESEARCH CORPORATION Topic: AF15AT35
ABSTRACT: Toyon Research Corp. and the Penn State Univ. propose research and development of innovative algorithms for classifying objects and activities observed in high-dimensional data, including video and hyperspectral imagery. The proposed algorithms include novel feature clustering techniques to enable effective characterization of intra-class and inter-class appearance variations in datasets ...STTR Phase I 2015 Department of DefenseAir Force
SBC: Analysis and Applications Associates, Inc. Topic: AF15AT40
ABSTRACT: Analysis and Applications and Associates, Inc. (AAA) proposes to develop software that evaluates effects of the hypersonic flow environment on electro-optic/infrared optical systems and vehicles for specific hypersonic flight profiles. We propose a high fidelity definition of the near-field flow, using the latest CFD and turbulence modeling technologies, to determine the environment from ...STTR Phase I 2015 Department of DefenseAir Force
SBC: UTOPIACOMPRESSION,CORPORATION Topic: AF15AT34
ABSTRACT: Over the past decade, there has been a sustained interest in Global Positioning System (GPS) denied navigation technologies for unmanned aircraft systems (UAS). This has been primarily due to the well accepted susceptibility of GPS signals to intentional jamming or unintentional interference and blockage. One of the challenging problems in GPS-denied navigation is handing off moving targ ...STTR Phase I 2015 Department of DefenseAir Force
SBC: CFD RESEARCH CORPORATION Topic: AF15AT33
ABSTRACT: This project will develop and demonstrate a software package based on coupled Fokker-Planck (FP) - Fermi Kinetic Transport (FKT) models and full-wave Maxwell electromagnetic (EM) solver to accurately predict semiconductor device behavior from dc up through the mm-wave and THz frequency ranges. The FP model provides accurate non-equilibrium occupation functions for hot electrons with real ...STTR Phase I 2015 Department of DefenseAir Force
SBC: PARASIM INC Topic: AF14AT07
ABSTRACT: In this proposal, a team comprising ParaSim Inc. and the University of Utah will examine the feasibility of generating curved high-order meshes from hybrid linear meshes while retaining a given boundary geometry. Specifically, a preliminary design of a software package for creating high-order (up to 4th order and higher) hybrid-element meshes for complex geometries will be developed. S ...STTR Phase I 2015 Department of DefenseAir Force
SBC: HYPERCOMP INC Topic: AF14AT07
ABSTRACT: We propose here a robust production-level high-order mesh generation software for complex geometries. High order accurate numerical methods are becoming increasingly popular in the present time and have demonstrated a great measure of success in efficient error-controlled simulations for a wide variety of important problems. A curved geometry and mesh generation system is essential in m ...STTR Phase I 2015 Department of DefenseAir Force
