Combustor Lean BlowOut (LBO) is a significant challenge in modern military gas turbine combustors. LBO can occur either during rapid engine deceleration or during operation at idle conditions with water/steam ingestion. Current practice is to design adequate safety margins to avoid the onset of blowout. However, significant engine performance improvements can be realized though the development o ...

In high F/A military gas turbine combustors such as JSF, localized pockets of carbon monoxide and hydrogen can exit the combustor, causing severe cooling challenges for designers of turbine inlet guide vanes. Instead of cooling the vane, cooling air can interact with the hotpath flow to release heat near the vane surface, resulting in durability challenges and possibly catastrophic damage. In this ...

Improved head and hearing protection is required for aircraft maintainers working on a carrier flight deck during launch and recovery operations. The current head protection is inadequate in many aspects including impact protection, hearing protection, cleaning, comfort, and compatibility with night vision goggles (NVGs) and with chemical, biological, and radiological (CBR) equipment. Creare pro ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

The US Navy is seeking improved capabilities to quickly and efficiently generate 3-D target templates (or “site models”) to support such operational systems as the Tomahawk Command and Control Systems (TC2S), Distributed Common Ground Station-Navy (DCGS-N), and collateral damage assessment (e.g., CDET and FastCD). There are two parts of interest. The first is to extract valid and reliable 2-D ...

Vessels of all types have a limited useful life and must ultimately be dismantled or scuttled as artificial reefs, with wastes properly disposed. The Navy is seeking a means of removing hydrocarbons from inactive ships prior to ship dismantling or sinking as an artificial reef. The Phase I project investigated the use of a biological/mechanical system that was capable of removing free-phase oil w ...

There are a growing number of scenarios where remote equipment and vehicles must be operated in environments unsafe for human presence. Ideally the remote vision system should mimic physical presence as much as possible. Steadily, the demand for stereoscopic (3D) viewing increases, in order to preserve depth of field information, and to ‘immerse’ the operator as much as possible in the scen ...

The military’s recognition of the need to share battlefield intelligence between all branches of the armed services has led to the development of the Joint Fires Network (JFN). In JFN, intelligence data from the many sensors deployed must be assimilated for targeting information. Computers perform some of these operations while people perform others. The bottom line is that there are massive ...

THE OBJECTIVE OF THIS RESEARCH IS TO INVESTIGATE NEW FAULT TOLERANT ALGORITHMS AND MODELING ENVIRONMENTS FOR USE IN RELIABILITY DESIGN AND EVALUATION OF MODEL MULTIPROCESSOR NETWORKS SUCH AS FLIGHT CONTROL SYSTEMS AND HIGH-RELIABILITY COMPUTER SYSTEMS FOR NUCLEAR PLANT SAFETY SYSTEMS AND OTHER MISSION-CRITICAL WEAPON PLATFORM COMPUTERS. EMPHASIS IS PLACED ON FAULT TOLERANCE RELATED TECHNIQUES WHIC ...

Effective collective protection fabrics must have a reliable closure system. During our Phase I Work Plan, Sigma-K began developing a Hermetic Textile Closure Hardware (HATCH) system. The HATCH combines both a magnetic and geometric self locking mechanism that will provide a hermetic seal when closed. Our current Phase I successes include developing self closing samples that can provide a hermetic ...
