Aircraft inspection and maintenance is dependent on seamless integration of human and machine components, but the underlying reasons for certain maintenance tasks can be difficult to translate in training terms. Planet LLC, along with its instructional systems design partner American Systems Corporation, proposes to create a tool to tackle physical force and natural phenomenon effects. This Phase ...

Soil texture is a critical soil information input to site suitability, mobility, counter-mine, and engineering models. Traditional methods of obtaining soil information are inefficient, inconsistent, and could require time-consuming and expensive laboratory analyses. In addition, a high level of soil expertise may be required on-site. A soil imaging system could provide a more efficient and con ...

ORBITEC PROPOSES TO DEVELOP A MEANS TO PRODUCE AND UTILIZE SOLID OXIDIZERS IN A COMBUSTION CHAMBER. CONDENSION GASEOUS OXYGEN DIRECTLY TO THE SOLID STATE APPEARS AN INTRACTABLE APPROACH BECOUSE OF LOW DENSITY OF THE FROST FORMATION. RAPID FREEZING FROM THE LIQUID PHASE HOWEVER, ASSURES A DENSE, COHERENT SOLID PHASE FORMATION. TO SIMPLIFY DELIVERY TO THE COMBUSTION CHAMBER, WE PROPOSE TO USE THE CO ...

Oxide coatings previously developed to protect polyimide and carbon/carbon composites in low earth orbit are brittle and crack upon flexing. Adding small amounts of polytetrafluoroethylene (PTFE) increases coating flexibility but reduces atomic oxygen (AO) resistance and mechanicall durability. Coatings developed in this project will use inorganics with potentially greater flexibility (such as she ...

THE COMPRESSION SYSTEMS OF CURRENT AND FUTURE GAS TURBINE ENGINES REQUIRE EXTREMELY TIGHT CLEARANCES IN THE HIGH PRESSURE COMPRESSOR IN ORDER TO OBTAIN AND MAINTAIN HIGH PERFORMANCE AND EFFICIENCY. MANY OF THE CURRENT COMPRESSORS USE THERMAL SPRAY COATINGS DEPOSITED ONTO THE COMPRESSOR SHROUDS WHICH ARE DESIGNED TO BE EASILY ABRADED BY THE TURBINE BLADE TIPS, THUS ACHIEVING TIGHT CLEARANCES. UNFOR ...
