In the past several years, a number of large-scale prototype electric Vertical Takeoff and Landing (eVTOL) aircraft have been flight tested by aircraft manufacturers to achieve their commercial product development goals for the Advanced Air Mobility (AAM) market. Owing to intellectual property and propriety information concerns, however, relatively few large-scale eVTOL aircraft have been flight t ...

Generation of quantum light deterministically and at telecommunications wavelengths has been an insurmountable challenge for execution of quantum networking protocols in a scalable manner, as telecom photons can travel with minimal loss through optical fiber networks, distributing quantum entanglement over long distances. Semiconductor quantumnbsp;dots have emerged as the most promising platform t ...

We are proposing the fully autonomous science facility REALISE for suspended biological cultures that can both incubate organisms over long periods of time (30 days to 9 months) but also perform in-situ analysis of samples using bright-field and three-color fluorescence microscopy. REALISE will be based heavily on functionality, components, and experience from past Shuttle, ISS, and Orion heritage ...

NASA manages $40B in facility assets with an inventory of more than 5,000 facilities. Over 83% of this infrastructure is beyond its design life, and the agency faces a deferred maintenance backlog of $2.77B. An effective method to address this challenge and achieve digital transformation is through Enterprise Architecture (EA) and the use of Model-Based Systems Engineering (MBSE) methods.nbsp;Duri ...

Rocket propulsion system development is enabled by rigorous ground testing to mitigate the propulsion system risks inherent in spaceflight. Helium is used in piping and engine purge processes to inert liquid hydrogen systems. The cost of helium is increasing as the supply diminishes, impacting testing of the rocket engines for space propulsion systems. There is an outstanding need within NASA prop ...

Vescent Photonics, LLC (Vescent) in collaboration with the Massachusetts Institute of Technology Lincoln Laboratory (MIT-LL) proposes to develop a compact ultra-narrow linewidth laser based on photonic integrated chip (PIC) technology for next-generation fieldable quantum sensor applications including optical atomic clocks, two-way time transfer, and precision inertial force and gravity sensing.nb ...

Mesh generation for wall-modeled large eddy simulations (WMLES) based CFD simulations represents a critical area of research as there are significant challenges which must be overcome before this technology can be adopted for widespread use.nbsp; Two critical challenges associated with these scale-resolving simulations is mesh size and mesh quality.nbsp; Mesh size represents a critical challenge a ...

NASA is interested in improving the method to control CO2 and water in the Exploration Extravehicular Mobility Unit (xEMU) to meet the ambitious objectives of the Artemis program, which includes human presence on the surface of the Moon and Mars. The technology that is planned to be used is the RCA which utilizes two beds that are alternately used to remove CO2 and H2O and then are regenerated by ...

GTLrsquo;s breakthrough ultra-lightweight composite dewar-tank technology is game changing by providing hydrogen weight fractions in excess of 59% for small tanks, with over 70% achievable with medium scale LH2 tanks, including vacuum insulation. This capability addresses a critical need in the conversion of single-aisle aircraft from Jet-A to liquid hydrogen to eliminate carbon emissions. With GT ...

Ultrasonic Technology Solutions (UTS) is based in Knoxville, Tennessee, and formed as a spin-off start-up from Oak Ridge National Laboratory (ORNL) is proposing to develop an ultra-fastnbsp;ultrasonic washing and dryer combination for space applications.NASArsquo;s Life Support and Habitation Systems Focus Area seeks key capabilities and technology solutions that enable extended human presence in ...
