SpaceWorks and the Georgia Institute of Technology propose an integrated predictive diagnostic system for evaluating the condition of spacecraft moving parts. Specific mechanisms to be addressed include reaction and momentum wheels, gimbals, flywheels and cryocoolers. To accurately estimate the remaining life of components, an intelligent diagnostic and prognostic monitoring and computational st ...

Syntonics is proposing a radically innovative concept: a Pixel-Addressable Reconfigurable Conformal Antenna (PARCA) that could meet the KV's requirements for simplicity, mass and robustness while providing near-all sky coverage. The feasibility of PARCA has not been demonstrated (yet), but earlier work by others suggests it merits further investigation, hence its suitability for a Phase I study. S ...

TDI proposes to develop high purity GaN materials having room temperature carrier concentration from 1014 cm-2 down to 1012 cm-2 using novel technological approach based on advanced hydride vapor phase epitaxy (HVPE). The HVPE technology is known to produce epitaxial layers and bulk GaN materials with low defect density and high carrier mobility. Recently, TDI demonstrated HVPE growth of GaN and ...

TDI proposes to produce combinatorial GaN and AlGaN samples library having a wide range of doping and fabricated using a variety of surface treatment conditions. These samples will be grown using novel technological approach based on advanced hydride vapor phase epitaxy (HVPE). This method is known to produce bulk GaN materials with low defect density. Recently, TDI has demonstrated high throughpu ...

The goal of this proposal is to demonstrate large area manufacturing technology for high performance AlGaN/GaN high electron mobility transistors (HEMTs) for radar and RF applications. TDI proposes to develop novel epitaxial technology for HEMTs structures on large area sapphire substrates based on hydride vapor phase epitaxial (HVPE) approach. TDI recently demonstrated the first-ever nitride HEM ...

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 ...

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 ...

Xenotran proposes to develop a forward error correction device for use in Ballistic Missile Defense systems for ensuring survivable and robust communications between the Battle Management, Command, Control, and Communications elements and an ExoAtmospheric Kill Vehicle (EKV) during flight. Communications in this channel is known to be subject to Rayleigh and Ricean fading, intentional jamming and ...

In this Phase I program, Advanced Ceramics Manufacturing will develop a processing method to manufacture ceramic propulsion components. ACM will demonstrate the utility of a high temperature hot isostatic pressing (HIP) consolidation process to manufacture carbide propulsion components. Low cost light weight components offer increased performance capabilities in numerous applications including m ...
