About Subsonic Vehicle Technologies and Tools Project
Project Overview NASA’s Subsonic Vehicle Technologies and Tools (SVTT) project develops technologies and tools for various types of aircraft that fly in different speed regimes, including next-generation vertical take-off and landing and fixed-wing subsonic aircraft. The research advances knowledge, technologies, and concepts that enable major steps to lowering operating costs of the next-generation single-aisle aircraft. […]
Insights into Spallation Mechanisms of Thermal Protection System Materials from Mass Spectrometry and HyMETS Testing
Download PDF: Insights into Spallation Mechanisms of Thermal Protection System Materials from Mass Spectrometry and HyMETS Testing An effort was undertaken to investigate the mechanisms responsible for internal pressure build up within thermal protection system (TPS) materials subjected to high-enthalpy environments. Understanding how gases evolve, migrate, and interact with the microstructure of a TPS is essential for […]
Computational Modeling of Failure at the Fabric Weave Level in Reentry Parachute Energy Modulators
Download PDF: Computational Modeling of Failure at the Fabric Weave Level in Reentry Parachute Energy Modulators Energy modulators (EM) are textile mechanical devices designed to dissipate snatch loads that occur when parachutes are deployed. Although critical for mitigating shock loads, recent flight testing has shown increasing variability in EM behavior, raising concerns about their performance predictability and […]
Ice to Fuel: NASA Tests Technology for Refueling Landers
The farther the destination, the more fuel a rocket needs. The more fuel the rocket carries, the heavier the spacecraft. The heavier the spacecraft, the more fuel it requires to launch. Experts at NASA’s Glenn Research Center in Cleveland are testing technology that could solve this problem. The CryoFILL (Cryogenic Fluid In-Situ Liquefaction for Landers) project could transform the way NASA fuels future space exploration missions, reducing costs and extending the duration of planetary surface operations. “If […]
