Research is proposed for the development and implementation of state of the art, reduced order nonlinear aeroelastic models for multidisciplinary/multi-fidelity optimization problems. 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 met ...

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 ...

Aniuk Consulting, LLC, proposes to create a GIS software toolkit for easily converting NASA HDF-EOS data into formats that can be readily used within a Geographic Information System (GIS) or other geospatial software programs. The Hierarchical Data Format (HDF) is a widely used scientific data format and serves as the standard format for NASA EOS products. The HDF-EOS toolbar will allow a user t ...

Military network environments will be subject to both internal and external threats for the foreseeable future. Internal threats to cyber networks from U.S. personnel receive little attention in comparison to external threats; yet, the consequences can be even more devastating. The lack of tools for understanding insider threat, analyzing risk mitigation alternatives, and communicating results e ...

EVA radio is an important integral part of lunar missions and beyond. To minimize power consumption and mass of an EVA radio, innovative solutions are needed for the design of various modules ranging from RF front end to networking protocols. In this protocol, a comprehensive design architecture that can achieve ultra-low power miniaturized EVA radio is proposed. Under this architecture, new MEMS- ...

Innovative network architecture, protocols, and algorithms are proposed for both lunar surface networks and orbit access networks. Firstly, an overlaying architecture is proposed to seamlessly integrate lunar surface networks and orbit access networks. Secondly, for lunar surface networks, a network architecture based on hybrid mesh networking technologies is developed to support both fixed and mo ...

An innovative data collection and analysis approach is proposed to enable body mount magnetometers for space application. In order to achieve high accurate magnetic field measurement in space, the magnetometer has to be located in a âmagnetically cleanâ place, where the magnetic field from spacecraft is negligible. Usually, the magnetometers are placed on deployable booms, so that the field sens ...

The proposed study aims at accelerated development of Mo-Si-B-X (X=Ti, Zr, Hf, Re, Mn) alloys with an optimized balance of properties, via an approach of integrating thermodynamic modeling with experimental study.   On the basis of the Mo-Si-B-X (X=Ti, Zr, Hf) database developed in Phase I, a thermodynamic database of the Mo-Si-B-O-X (X=Ti, Zr, Hf, Re, Mn) system will be developed using the Calp ...

CompuTherm, LLC proposes a pilot project to develop a modeling tool that can be used to assess the durability of environmental barrier coatings (EBCs) for ceramic matrix composites (CMCs) under combustion environment. The modeling tool includes a thermodynamic database for the gas phase, a thermodynamic database for the silicate system (EBCs), and a computer software package that deals with thermo ...
