Propulsion systems require rigorous and highly instrumented testing to enable a comprehensive analysis of performance and to minimize risks associated with space flight. Current testing instrumentation methods can be replaced with embedded sensor systems that are used for monitoring remote, hazardous, or inaccessible locations, while reducing cabling and power consumption. The additional informati ...

Cooperative robots can explore the surface of planets with higher efficiency and lower mission risk, perform novel and precise resource and science surveys, and gather and share resources and information with other assets to bring planetary exploration. In order to work together more efficiently and effectively, robots must understand their location relative to their peers, which is challenged in ...

This Multiband Software Defined Radio (SDR) sensor system proposal will demonstrate the ability to operate within multiple frequency bands and across multiple technology platforms in a single transceiver. The center frequencies and bandwidths chosen are representative of current demonstrated commercial or research devices and bands used: 400 MHz, 900 MHz, and 2.4 GHz ISM bands, with bandwidths of ...

Sensatek Propulsion Technology, Inc. proposes to demonstrate the feasibility of a wireless, passive, nanoparticle-based sensor system. The sensor in its current form can be used to measure real time temperatures and pressures wirelessly without the need of an external energy source. It should be noted that the same sensing principle can be used for strain monitoring as well. It comprises of a micr ...

We propose to develop a method to effectively utilize the massive amount of image and range data that cameras and laser scanners can generate for an autonomous navigation system. Our innovative approach is to use deep learning to detect and segment only the most useful portions of the data and to use that to build better 3D models. We have proven methods for building accurate 3D models of the en ...

Use of thin ply composites offers good potential for significant mass savings for aerospace structures besides its improved resistance to micro-cracking, fatigue, and delamination. However, mass savings due to thin-ply technology depends on material and fabrication technology, vehicle configuration, structural design, loads etc. Structural integrity of components made from thin plies need to be c ...

In contrast to the standard cold reservoir Variable Conductance Heat Pipe (VCHP) where for tight thermal control an electrical heater is used for the reservoir (wicked), Advanced Cooling Technologies, Inc (ACT) developed a hot reservoir VCHP with the reservoir thermally coupled to the evaporator. This novel feature will provide a tight temperature control capability without the need for control po ...

The research objective of the proposed work is to demonstrate feasibility of utilizing extensible modeling to create an AM knowledgebase for copper alloy, GrCop-84, and utilize it to design an AM process for GrCop-84. The work plan has three tasks: (1) Utilize process modeling to demonstrate feasibility of predicting AM process parameters for alloy GrCop-84 for the powder bed and blown powder proc ...

Niobium alloy (C-103) reaction control system (RCS) chambers have been used on numerous NASA programs. However at elevated temperatures, the strength of C-103 decreases significantly. Higher strength niobium alloys have been developed, but these alloys lack the formability of C-103. Recently, Additive Manufacture (AM) of niobium and C-103 has been demonstrated using powder bed electron beam me ...

This NASA Phase I STTR program would develop high performance, wireless networked cryogenic and minimum pressure sensors for remote monitoring in propulsion systems, using SOI (Silicon on Insulator) NM (nanomembrane) techniques in combination with our pioneering ceramic nanocomposite materials. We will improve the current mechanical and electrical model of semiconductor nanomembrane based sensor ...
