Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed.Process optimizations will be conducted ...

To address the urgent need for 3D flash-lidar technology for landing on solar system bodies and for spacecraft rendezvous and docking with satellites, an effort is proposed to fabricate, characterize, and test a versatile, high-sensitivity InGaAs APD 3D flash lidar and to advance the technology-readiness level (TRL) of lidar technologies suitable for NASA mission requirements. Leveraging an existi ...

Otherlab and the Faboratory propose that a key component of future NASA robot technology will benbsp;continuum joint-based fluidic actuation, valuable for its light weight, low packing volume, inherent shock amp; vibration isolation, and ability to interact safely with unstructured environments and near humans.nbsp;Over the course of our Phase I amp; Phase II projects we have developed such a nove ...

Electrified Aircraft Propulsion (EAP) research is part of NASA effort to improve aircraft fuel efficiency, emissions, and noise levels. New secondary battery chemistries are required to meet the 500 ndash; 700 Wh/kg cell level specific energy needs of UAM, all-electric helicopters and regional passenger aircraft. The cycle life, currently at asymp; 1500 ndash; 3000 cycles, also needs substantial i ...

Technology currently used for terrestrial navigation is extremely limited in the challenging environments on icy moons and ocean worlds such as Europa. Autonomous platforms used to collect data from beneath these ice and ocean surfaces cannot depend on access to satellite or any other electromagnetic communication. Autonomous systems in these environments are required to perform highly-complex tas ...

IFOS proposes an innovative Brillouin sensing system ndash; B*Sensetrade; ndash; for enhanced, distributed strain and temperature measurements in harsh environments. Brillouin sensing provides both temperature and strain measurement along the entire length of fiber, allowing the entire fiber to act as a sensor. B*Sensetrade; will enable identification of defects, such as fatigue cracking or excess ...

The proposed innovation is a new simulation tool for NASArsquo;s prediction and mitigation of hazardous electric fields created within the payload enclosure and similar electromagnetic field cavities of a launch vehicle and a spacecraft. The research will extend existing statistical power balance modeling methods to specific NASA requirements, includingnbsp; 1) Mapping the different electric field ...

he Distributed Multi-GNSS Timing and Localization (DiGiTaL) 2.0 system will leverage an existing partnership between Tyvak and the Stanfordrsquo;s Space Rendezvous Laboratory (SLAB) to advance the development required to provide precise knowledge of absolute and relative states of multiple orbiting nanosatellites necessary to mimic a gigantic spacecraft though a swarm of spacecraft with adjustable ...

Rotating Detonation Engine (RDE) design is challenging due to the lack of in-depth understanding of many key mixing and combustion processes. The RDE flow field is a nonuniform mixture of fuel and oxidizer concentrations with strong injector effects, large turbulence effects, multiple shockwaves, and shear layers. These inhomogeneities can lead to significant combustion inefficiencies which have a ...

Cornerstone Research Group Inc. (CRG) proposes to advance the state-of-the-art in space vehicle Thermal Protection Systems (TPS) through in-situ application and curing of a proprietary new resin technology called MG Resin, a family of thermoset formulations. The resins are being explored with DARPA, MDA, NASA, and the Army for a range of applications including C/C hot structures, TPS, syntactic in ...
