Achieving trustworthy and trusted autonomy starts early in the development process through performing hazard analysis, fault analysis, identifying mitigating requirements, and carefully and rigorously tracing those requirements all the way into design, models, implementation, and tests. However, traceability can be time-consuming, costly, and error-prone. To address these challenges, significant a ...

This project will advance technology for the automated assembly of large truss towers.nbsp; Assembly of truss-based structures is one of the leading candidates for establishing some of the early lunar infrastructure.nbsp; Specifically, joining technologies and robotic tools are required to enable autonomous/automated assembly of tall towers as well as shelters, domes and habitats.nbsp; Automated a ...

Materials Modeling Hub (MMH) software integrates modeling, product design, manufacturing, and usage cycle into a digital ecosystem to accelerate, simplify, and strengthen ideation through implementation. When combined with a viable materials information management strategy, modeling techniques can replicate and predict experimental outcomes and material performance with growing accuracy. In indust ...

Candent Technologies has successfully developed a low cavitation, high efficiency, extremely low acoustic signature marine propulsor, and is proposing to apply this advanced technology to the design and development of a compact, efficient, electric driven, stowable/retractable, Quiet Auxiliary Propulsion System that will meet and likely surpass the requirements for the SOCR (and 11m RHIB, as well ...

Metal additive manufacturing (AM), particularly, laser powder-bed fusion (LPBF) has transformative potential to achieve geometric design freedom at low production volumes. However, porosity and localized defects remain a significant challenge to implementation in mission critical aerospace applications. While the quality of LPBF is now competitive with or surpasses castings for established materia ...

During Phase I, Adiabatics, Inc. will use generator “best design” technical practices as well as new proprietary technology to develop a solution for high temperature cable and connector development for radio frequency (RF) applications in harsh environments.  First, Adiabatics, Inc. will develop a heat transfer model of its proposed RF cable.  The cable includes many materials that Adiabati ...

Traditionally, rotorcraft blade control is accomplished through a swashplate mechanism.  The swashplate mechanism is limited in that it does not allow for independent control of rotor blades.  Research efforts have shown that the ability to control rotor blade pitch independently, or Individual Blade Control (IBC), can offer advantages over conventional swashplate-based control.  Previous imple ...

Rolling element bearings used in small Unmanned Aerial Vehicle (UAV) engines have to be continuously lubricated to keep their functionality and avoid adhesive wear and excessive heat generation due to friction.  These fluid lubricated systems in small engines bear additional weight and cost of the subsystems in order to gain the benefits of low friction, damping and load bearing capacity.  To ...

The ArcSpear Jet Drone is a compact, high-thrust, electric jet powered VTOL drone that can fly at very high speeds and carry heavy payloads within a very small footprint, configurable to customer needs. ArcSpear can be outfitted to meet the objectives of the mission sets described in this topic.  The key differentiators of the ArcSpear are that it has no exposed rotor blades and yet still produce ...

The detection and mitigation of electric motor faults is vital to the safety and reliability of Urban Air Mobility (UAM) vehicles using electric propulsion. The proposed research aims to advance the state of the art of motor fault resilience research relevant to the NASA Revolutionary Vertical Lift Technology (RVLT) Project in two aspects: (1) develop fault resilience measures appropriate to the m ...
