The development of durable thermal protectin systems is one of the critical technologies to enhance performance and reduce operational costs of the next generation reentry space vehicles. k Technology Corporation (kTC) proposes development of an integrated thermal and structural thermal protection system (TPS) with low maintenance. The concept is to develop a leading edge TPS that is a load-carr ...

Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

This Phase II proposal outlines an ambitious research and development effort the objectives of which are to provide a high-voltage pulsed power generator that is compact, portable, reliable, exhibits a fast rise or fall time, and is capable of being command fired at a high pulse repetition rate (PRR) with low jitter. Another objective of this effort is to design and realize a feedback control sys ...

Ribbon Mills and its subcontractor Northrop Grumman Corporation (NGC) propose a Phase II program, to continue the research into advanced complex performs concepts utilizing weaving technology applied to state-of-the-art composites to enhance the revolutionary low frequency, conformal load-bearing antenna structures (CLAS) foliage penetration ground/air moving target indicator (FOPEN GMTI/AMTI) rad ...

The design of Unmanned Aerial Vehicles (UAV’s) is a complex process of creating a reliable system of reasonable cost that can survive in hostile environments. Although UAV’s have unique aspects to them, similar goals can be found in almost any complex, competitive product. One aspect of the design of these systems that tends to be both difficult and poorly supported with available computer ...

Taggants are small objects used to label things or people that need to be traced. Synthetic DNA Taggants are ideal for this, since very small amounts can be detected if the sequence is known, and can be disguised by natural DNA in the environment. Known protocols for DNA amplification (e.g. PCR) allow for very sensitive DNA detection, but suffer from disadvantages: the apparatus is not very portab ...

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 ...

This effort explores and assesses the options available for refractory composite leading edges cooled by embedded metallic heat pipes. Currently, the heat pipe cooled leading edges (HPCLE's) being investigated are fabricated primarily from refractory superalloys. However, even the best superalloys have a temperature limit of ~2400°F, which places substantial limitations on the possible geometry ...

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 ...

The use of coated HT superconductors in the ac windings of electrical machines offers the possibility of much lighter electrical devices. To use these conductors at proposed high frequencies, present “as-manufactured” conductor geometries must be modified to reduce their ac loss by using fine filaments and other topologies). Equally important are more global winding losses requiring suitable ...
