NextGen Aeronautics, Inc. and their partner, Virginia Tech, propose to develop a self-healing material for wire insulation using a class of poly(ethylene-co-methacrylic acid) (EMAA) and poly(tetramethylene oxide) ionomer polymers. The self-healing property of these materials is strongly correlated with the thermal processes that occur during and after damage initiation. Recent experimental result ...

The proposed program seeks to mature aerodynamic, aero-acoustic and performance modeling of e-VTOL vehicles during the transition phase of flight through the empirical testing of ESAerorsquo;s Scalable Modular Aerial Research Testbed (SMART) aircraft. The SMART aircraft is a subscale vertical take-off and landing (e-VTOL) vehicle designed with unique demonstrated capabilities (NASA SBIR Phase II 8 ...

AdTech Photonics, in collaboration with the Center for Advanced Studies in Photonics Research (CASPR) at UMBC, is pleased to submit this proposal entitled ?Very-High Efficiency, High Power Laser Diodes? in response to NASA?s needs in the such areas as diode pumped solid state lasers and Lidar Remote Sensing. Our goal is to develop ultra-high efficiency diode laser bars that can achieve greater tha ...

An all-electric aircraft testbed is proposed to provide a dedicated development environment for the rigorous study and advancement of electrically powered aircraft. The new testbed aircraft will be developed from an existing conventional airframe and provide a dedicated platform to study, design, and test electrically powered propulsion systems for use in commercial, military, and general aviatio ...

An unsteady, feature-based grid adaptation approach is proposed that addresses the main drawbacks of the current state of the art, namely, the lack of error control of the unsteady derivative terms, the lack of continuous representation of the mesh metric sensors in time, and the lack of adaptation of the mesh velocity to the dynamic flow features in hypersonic flows, e.g., shocks, mixing layers, ...

We propose to apply to planetary terrain mapping an alternative, multiresolution method, subdivision surfaces (subdivs), in place of conventional digital elevation maps (DEMs) and fixed-resolution meshes. The proposed research is innovative in that it presents a new setting for subdivs that demands novel extensions to subdivision algorithms, techniques and theory. The primary objectives of this wo ...

We build upon our prior work applying subdivision surfaces (subdivs) to planetary terrain mapping. Subdivs are an alternative, multi-resolution method with many advantages over conventional digital elevation maps (DEM's) and fixed-resolution meshes. The proposed research is innovative in presenting a new setting for subdivs demanding novel extensions to subdiv algorithms, techniques and theory as ...

Design and manufacture of a Liquid fuel injector optimized for Ultrasonic Additive Manufacturing. UAM delivers aerospace parts today at 97% of bulk material property and foil laydown rates at speeds significantly better then powder or filament process. UAM has traditionally been applied to 2-D planar surfaces. We will extend UAM into complex geometries and constructs suitable for rocket engine inj ...

Laser transmitters operating at a pulse repetition rate of 20 Hz to 50 Hz and with pulse energy from 30 - 50 mJ have been considered to be an enabling technology for CO2 measurement and optical communications. PolarOnyx proposes a novel approach targeting to make reliable high energy ultra large core fiber amplifier at 1.57 micron and employing our proprietary technologies in specialty fibers, spe ...

The team comprising OEwaves Inc. and UC Davis offers to develop and demonstrate a SiN-platform integrated photonic circuit suitable for a spectrally pure chip-scale tunable opto-electronic RF oscillator (OEO) that can operate as a flywheel in high precision optical clock modules, as well as radio astronomy, spectroscopy, and local oscillator in radar and communications systems. The effort comprise ...
