"This proposal shows how innovations in producing a family of CTE controlled, high thermal graphite aluminum composites will reduce manufacturing costs and improve system performance for specific BMDO, Navy, and commercial applications. Technologiesdeveloped by a graphite fiber producer, paper textile manufacturer, and metal composites foundry will create a superior thermal management material id ...

"Manufacturing technology development and integration of MMCC's 3- DPT, Tool-Less MoldT and Advanced Pressure Infiltration(APICT) technologies are proposed. Investment casting of preforms printed directly from a CAD or laser file and subsequent pressureinfiltration will enable parts to be manufactured without the added expense of tooling development. With investment materials being recycled and ...

"This proposal considers the potential of direct casting of micro channel cryocooler regenerators. Currently, cryocoolers use regenereators made of packed spheres, which decrease the efficiency of the regenerator and, of course, the cryocooler itself.This is an important issue when considering placing cryocoolers on satellites and the cryocooler itself utilized almost half of the power supply. T ...

"Increasingly demanding requirements for satellite electronics make it more difficult to effectively dissipate heat. One attractive means for managing spacecraft thermal environments is use of heat pipes to passively transfer heat to radiator panels. Weightis a major consideration, so composite materials are desired to replace metallic components. Carbon-carbon composites are used in radiator pane ...

"This SBIR Phase I proposal addresses a need for improved UV and deep UV filters for aerospace and defense applications. A new approach to the design and fabrication short pass filters, based on a new photonic material, will allow filters to be made withtransmission at wavelengths as short as 130nm or less. Both these properties are unachievable by any other means. In Phase I, it is proposed to ...

"Stoichiometric Lithium Tantalate crystal (SLT: 50/50) was found to be overwhelmingly superior over its congruent counterpart (CLT: 48.75/51.25) in nonlinear optical, electro-optical (EO), UV transparency, and domain reversion. Third harmonic generation viaperiodically poled structure inside this SLT crystal is expected to be more efficient, and to be more realistic for fabricating novel compact U ...

"Optical computation requires very specific optical interconnection schemes such as the in-plane sharp bends and the fast channel switching functions. The integration requirement with existing waveguide technologies further put many limitations on using thecurrent technologies to develop such a device with acceptable performances. This project proposes a new concept of using a new bistable mechan ...

"Mid¿ is proposing a novel and innovative strain-sensor-grid using pseudoelastic shape memory alloys. By embedding a grid of ultra-thin pseudoelastic wires in an epoxy and encapsulating the embedded grid between two layers of Kapton, the embedded sensorcan be used as a layer in a composite, thus forming a multi-functional structure. When one of the Kapton layers is replaced with a flex-circuit ...

"Hypervelocity missiles are currently dependent on the deflection of aerodynamic surfaces for flight control. These deflections and surfaces contribute significantly to the drag of the missile. By eliminating these surfaces it is estimated that anincrease of up to 30 % in speed of kinetic energy penetrators can be achieved.Mid¿ proposes to investigate the use of precisely controlled, fast actin ...

"A novel method of micro-mixing by inducing a low frequency resonant sonic vibration (LFRSV) in the fluid medium results in the increased rate of energy dissipation per unit mass of the fluid, allowing rapid and efficient dispersion of solids, gases, andimmiscible liquids. This enhanced way of achieving micro mixing, can be used for dispersing nano particles in making gel propellants. Rheologica ...
