In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

UAVS (Unmanned Aircraft Vehicle System) integration with naval vessels is currently realized in limited form. This is largely due to the fact that the operational envelopes of these vehicles are based solely on at-sea flight testing. In addition to the complexities involved with at-sea flight testing, the unsteady nature of ship-airwakes and the use of automated UAV control software necessitates ...

The proposed project will rectify the current bottleneck in the simulation of 3D magnetic fields around high-current pulsed power devices. In the existing software, fields in the air are approximated by an artificial magnetic diffusion equation, which is both computationally expensive and nonphysical. The proposed solution avoids any nonphysical quantities and relies on exact conditions for the qu ...

In this SBIR project, a preliminary design of a highly accurate, highly repeatable impulse thruster will be completed. ASI, together with ATK, proposes to complete the preliminary design in parallel with the development of a comprehensive thruster model in a Monte Carlo environment that will account for every contributor to repeatability in the final product. Using modern uncertainty analysis te ...

Understanding the response of solid rocket motors under cookoff and projectile impact scenarios is important to the safety of the military’s weapon arsenal. In this SBIR, CFDRC, teamed with Merrill Beckstead of Brigham Young University (BYU), propose to develop an improved modeling tool for simulating the response of solid rocket motors containing AP/HTPB/AL propellant to external heat and impa ...

Understanding the response of solid rocket motors under cook-off conditions is important to the safety of the military’s weapon arsenal. In this SBIR, CFDRC, teamed with Merrill Beckstead of Brigham Young University (BYU) and ATK Launch Systems, proposes to develop a software toolkit for simulating the response of solid rocket motors (SRM) to fast cook-off events. The complete software package w ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

Under AFRL Contract FA8650-05-M-5214 Phase I, CFDRC has developed and demonstrated the foundation of a comprehensive code for modeling the Cold Hearth Melting (CHM) processing of Titanium alloys. The code includes effects that accurately predict the transient temperature distribution, flow patterns, skull shape, species evaporation, and particle fates in the hearth region for a given set of dynam ...

The goal of the proposed research is to develop a unified computational framework integrating adequate physical models for simulating complex non-equilibrium plasmas. Plasma dynamics is characterized by disparate spatial and temporal scales each described by appropriate physical models. The project aims to classify possible scenarios and develop general recipes for clustering phase space to dynami ...

We propose to develop a Health and Environmental Risks Assessment Capability (HERAC) that will allow Air Force personnel and related contractors to develop actionable, scientifically based, health and environmental risks assessments of maintenance tasks upon aircraft and other weapons. Presently, no capability exists to effectively model and simulate the microscale (from 2 to 50 feet) transport an ...
