We propose to mature LG-X glider technology by manufacturing full-scaled prototypes and characterizing them in land-based flight-testing by using commercial aircraft to drop the gliders. Validated components such as the landing parachute, folding wing mechanism, and autopilot control system will undergo integrated flight-testing. Logistic Gliders will provide a considerable cost share to support ...

SixPoint Materials will create low-cost, high-quality vertical gallium nitride (GaN) substrates using a multi-phase production approach that employs both hydride vapor phase epitaxy (HVPE) technology and ammonothermal growth techniques to lower costs and maintain crystal quality. Substrates are thin wafers of semiconducting material needed for power devices. In its two-phase project, SixPoint Mate ...

We propose to design, fabricate and test turbine blade configurations in a flow driven by a continuous detonation wave engine with a goal of understanding the physics and efficiency of such an integrated device. Analysis based on CFD models and cycle perf

GaN-based devices are the basis of a variety of modern electronics applications, especially in optoelectronics and high-frequency / high-power electronics. These devices are based on epitaxial films grown on single-crystal wafers. The single-crystal wafer substrates are limiting because of their size, expense, mechanical properties and availability. If one could make GaN-based devices over large a ...

NanoSD, Inc. with its partners will develop a transparent, nanostructured thermally insulating film that can be applied to existing single-pane windows to reduce heat loss. To produce the nanostructured film, the team will create hollow ceramic or polymer nanobubbles and consolidate them into a dense lattice structure using heat and compression. Because it is mostly air, the resulting nanobubble s ...

We propose to construct a parametric amplifier and oscillator system for generating and detecting gravitational microwaves using a moving, impermeable superconducting membrane as its active element. A configuration of three adjacent, high-Q SRF cylindrical cavities will be constructed, consisting of a single pump cavity separated from a double signal and idler cavity by means of this membrane, ...

The primary objective of the Nano-Optomechanical Massive MEMS Accelerometer (NOMMA) project is to develop a chip-integrated optomechanical Micro-Electro-Mechanical Systems (MEMS) accelerometer with 100 ng/Hz1/2 sensitivity and 10 kHz bandwidth using high

Launch vehicles experience extreme acoustic loads during liftoff driven by the interaction of rocket plumes and plume-generated acoustic waves with ground structures. Currently employed predictive capabilities are too dissipative to accurately resolve the propagation of waves throughout the launch environment. Higher fidelity non-dissipative analysis tools are critically needed to design mitigatio ...

The liberation of particles induced by rocket plume flow from spacecraft landing on unprepared regolith of the Moon, Mars, and other destinations poses high mission risks for robotic and human exploration activities. This process occurs in a combination of "extreme environments" that combine low gravity, little or no atmosphere, rocket exhaust gas flow that is supersonic and partially rarefied, an ...
