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 ...

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 ...

Precision Combustion, Inc. (PCI) proposes to develop and demonstrate simultaneous H2 generation and compression with intermediate-temperature solid-oxide membranes. The innovation is based on a novel cell architecture and materials, and processing techniques recently developed at PCI. Proof of concept testing of the new cell architecture indicated potential to be to be lightweight and presents sev ...

Alphacore and Arizona State University (ASU) propose the development of hardware and software solutions for digital twins of regions of strategic interest on the moon, for robotic mission planning in preparation for and potentially during ARTEMIS human missions. We are developing a next generation imaging system for terrain mapping in dynamic lighting and thermal conditions. When deployed aboard r ...

Reliable Vamp;V and testing of fault management (FM) during design, implementation and operations is an essential part of systems engineering design and development of critical space programs such as the SLS, Gateway and Artemis.nbsp;NASArsquo;s Mission and Fault Management group currently utilizes SAM to assess nominal andnbsp;FM algorithms prior to full-scale real-time testing, to proactively ch ...

Qualtech Systems, Inc. (QSI) in collaboration with Dr. Stephen B. Johnson of Dependable Systems Technologies (DST) proposesnbsp;a novel, causal graph-based model and a systematic modeling methodology for assessing damage propagation due to one or multiple originating faults and how the propagation affects and damages other components. In fault propagation, downstream components from the root-cause ...

One of NASArsquo;s major technology needs is to increase system autonomy and resilience. To accomplish this, an important tasknbsp;is to connect fault management (FM)nbsp;to systems engineering (SE) and operations.nbsp;In highly reliable systems there must be some means to detect and respond to failure of those functions. Identifying and allocating the requirements and functions for these capabili ...

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 ...

Aloft Sensing Inc. (Aloft) proposes to adapt and establish the feasibility of our scalable Radar Vision Systems (RVS) for operation on solar system bodies. RVS consist of state-of-the-art multichannel mm-wave radars coupled with our patent-pending position, navigation, and timing algorithms (AloftPNT). Demonstrated through simulations and field experiments, these systems achieve both accurate self ...

Two of the largest and critical components in virtually all NASA Power Processing Units (PPUs) of spacecraft, probes and landers, are energy buffer and DC-link capacitors, used to minimize ripple current, voltage fluctuations and transient suppression. Current capacitor technologies have severe performance limitations at cryogenic temperatures, especially when combined with exposure to radiation. ...
