Award Data

Current IR window materials, while offering good optical properties are often structurally inadequate in their ability to perform in ever more increasingly hostile environments. Optically transparent, hard ceramic materials such as spinel, ALON and sapphire while expensive to fabricate and finish are considered viable candidates against scratch and rain erosion and severe thermal environments. P ...

Aspherical domes provide lower drag and radar signatures than hemispherical window designs but conventional finishing technologies have not been able to provide adequate optical surfaces. The fabrication of aspherical windows therefore remains a relatively under-developed technology for E/O windows for hypervelocity missiles. Development of deterministic microgrinding, coupled with magnetorheol ...

The ORCLE program is a hybrid high-bandwith communication design based on laser, infrared and radio transmissions between aircraft and other communication points. The communications terminals that protrude into the air stream around the aircraft require a protective cover that can reduce drag and minimize damage from heat, dust, and rain. Technical requirements for suitable windows/domes include ...

While aspherical dome geometries provide enhanced aerodynamics versus hemispherical domes, they have been problematic to manufacture due to inadequate finishing techniques. However, recent advances in finishing technology have made their production possible. Magnesium aluminate spinel is a hard, transparent material, which is currently being scaled up to produce hemispherical transparent domes to ...

This proposal addresses the need for compact, lightweight packaging to cool high heat producing electronics. Technology Assessment & Transfer, Inc. (TA&T) proposes to develop three dimensional (3D) packages consisting of stacked AlN substrates with integral microstructured flow-through heat exchangers. Of the packaging materials in common use today, AlN offers the best coefficient of thermal expan ...

75832-Magnesium aluminate spinel is a promising structural and radio frequency (RF) window material for nuclear reactors, due to its remarkable neutron and ion radiation resistance at high temperatures. However, little, if any, effort has been expended in optimizing the strength, creep, toughness, and thermal shock properties of spinel structural components for advanced nuclear applications. Thi ...

79411S Lasers perform a critical role in injectors of high quality (low emittance and high phase-space brightness) electron beams to linear accelerators. Radio frequency (RF) photoinjectors (in which electrons packed tightly in phase-space are produced from a photocathode surface properly embedded in a high electromagnetic field inside a radio frequency cavity and subjected short pulse laser irra ...

A high-strength low-cost alternative to single-crystal sapphire is required to meet the increased performance demands of the Navy's next-generation E/O applications. Technology Assessment & Transfer is the leading supplier of polycrystalline transparent spinel ceramics. Spinel, with a hardness that is slightly lower than that of sapphire and a lower strength (350 MPa vs. 750 MPa), has the benefits ...

Technology Assessment and Transfer Inc. (TA&T) proposes fabricating high power magnetic cores with integrated fluidic cooling channels to meet the requirements of emerging inductors and transformers for power electronics applications. TA&T has developed processes for fabricating monolithic ceramic components with complex geometry, including internal cavities and channels that cannot be fabricated ...
