Research is proposed for the development and implementation of state of the art, reduced order models for problems in nonlinear aeroelasticity. Highly efficient and accurate aeroelastic simulation tools will be constructed based upon the mathematical formalism of optimal prediction theory and a novel implementation of a filtered harmonic balance solution methodology. The implications of the propos ...

In this proposal, TiER1 Performance Solutions and Alion Science and Technology offer to identify requirements and specifications, and implement a proof-of-concept prototype tool to support human factors evaluations. This prototype, called the Human Factors Evaluation Automated Tool (HFE-AT), will provide guidance, for non-human factors personnel, to address human factors-related aspects of the en ...

This small business innovation research is intended to develop and proof the concept of a highly efficient, high temperature rechargeable battery for supporting Venus exploration missions. The proposed battery will be built upon a tubular, alkali metal ion-conducting, highly refractor, beta"-alumina-solid-electrolyte (BASE) sandwiched between an alkali metal anode and a metal salt cathode. In Ph ...

The overall objective of the proposal is to design, develop and demonstrate a potentially portable Compton x-ray scatter 3D-imaging system by using specially designed rotationally movable x-ray source and x-ray detector, and the development of a suitable 3D-processing computer model. The proposed rotational configuration will allow the acquisition of multiple projections or images 360

The proposed research program aims at developing a variable-fidelity software tool set for aeroservothermoelastic-propulsive (ASTE-P) modeling that can be routinely applied to the design of aerospace vehicles. The tool set can be applied to conventional vehicle types as well as hypersonic vehicles. The major issues involved in ASTE-P modeling and simulation will be significantly and extensively in ...

CFD modeling and simulation has been heavily invested in decades of manpower by a large community of researchers. However, the excessive numerical diffusion inherently caused by discretization errors plus the possibly largest/finest grid requirement for rotor wake modeling prevents CFD to be routinely used in practical engineering calculations. The proposed Gradient Transport Correction (GTC) meth ...

The proposed research program will develop a physics-based identification, modeling and risk management infrastructure for aeroelastic transonic flutter and limit-cycle oscillations (LCO). This capability will be built upon high fidelity state-of-the-art theoretical/computational methods as validated and verified by available experimental data bases, and will include (1) rapid flutter boundary det ...

The proposed work aims at developing techniques that will address the current limitations of Cartesian-based Navier-Stokes CFD schemes by exploring three promising methods of implementing improved wall boundary conditions. The three methods are based on: (1) the diamond stencil approach of Delanaye et al., (2) the extrapolation boundary condition work by Marshall and Ruffin, and (3) the Material P ...

This project develops a display for visually representing physiologic data, to enhance a non-physician astronaut's ability to assess, comprehend and rapidly stabilize an injured crewmember's vital signs. With longer duration missions further from earth involving more dangerous activities, the need for more autonomous emergency medical care becomes acute Our prior research has shown that graphic di ...
