BHL? technology offers the means to reduce the mass of cryogenic propellant tanks by 75% relative to state-of-the-art metal tanks. Since propellant tanks are generally the largest individual mass item on a launch vehicle or spacecraft, this mass savings of this magnitude can have profound effect on vehicle performance. A conceptual design of a spherical BHL cryotank for the NASA Morpheus Lander ...

Frozen tissue samples represent the state of the art in tissue preservation in many molecular analysis techniques as well as in in membrane analysis using free-fracture techniques. Rapid freezing eliminates the artifact caused by ice crystal formation within the tissues. Ice crystal nucleation and growth occurs between 0?C and -20?C typically. To avoid this damage and minimize destruction of pr ...

The use of eddy-current methods to detect damage in aerospace structures,and to characterize materials is well established, and is a key item to ensure that the risk of structural failures meets the strict damage tolerance requirements established by NASA. This is especially challenging when one considers that common aerospace structures are made from such disparage materials as aluminum, titanium ...

The proposed innovation is a 3D metal printer, which offers the unique ability to fabricate metal components and tools in space. The proposed system will accomplish this task through the utilization of a two-stage filament melting process whereby a metallic filament is first heated to Curie temperature through induction and then deposited on a build platform where it is fused to the previous layer ...

GTL?s SNS technology aids in the operation of new or existing structural health monitoring (SHM) systems by integrating data and power pathways into the structure. The use of this technology within a composite structure would allow engineers to place sensors from an SHM system directly where they are needed on a structure with instant power. GTL?s SNS technology offers the potential for developers ...

DEC-Shield technology offers the means to generate electric power from cosmic radiation sources and fuse dissimilar systems and functionality into a structural component to create a Multi-functional Structure (MFS). DEC-Shield integrated into MFS technology can be used to generate electric power and provide radiation protection in a space vehicle; even maximizing that protection by spreading the ...

PC Krause and Associates is partnering with Purdue University, EleQuant, and GridQuant to create a hybrid modeling capability. The combination of PCKA?s extensive dynamic modeling experience, Purdue?s work in electromechanical systems analysis, and GridQuant and Elequant?s development of the HELM algorithm uniquely positions the team to create this technology. HELM is a novel algorithm that solves ...

An electromagnetic pulse (EMP) attack could cause widespread outage of the commercial electric power system that could last for weeks to months. Microgrids for defense critical infrastructure (DCI) should thus be equipped to operate in islanded mode for extended periods of time using only local fuel storage and renewable energy sources. The primary difference between operating a microgrid in islan ...

While aluminum casing materials provide some enhanced performance and thermal loading to explosive ordinance, their overall effectiveness is highly limited by incomplete combustion and long residence times. In order to reduce these problems, the casing material must be designed to facilitate rapid fragmentation through either specialized casing geometries or greatly refined initial particle sizes. ...

Establish a radiation-aware analysis capability in a commercial EDA design flow that will enable first-pass success in radiation-hardened by design (RHBD) for DoD ASICs in much the same way that existing EDA design suites ensure first pass functionality and performance success of complex ASICs destined for commercial applications. Layout-aware, calibrated single-event radiation models that captur ...
