We propose the development of a user-friendly software tool for estimating the electric field distributions within spacecraft enclosures based on the Power Balance (PwB) method and enhanced by a database of experimentally determined Absorption Cross-Sections (ACS) of common equipment, components and cables.The software will be built around an already developed PwB solver that determines the statis ...

Technology currently used for terrestrial navigation is extremely limited in the challenging environments on icy moons and ocean worlds such as Europa. Autonomous platforms used to collect data from beneath these ice and ocean surfaces cannot depend on access to satellite or any other electromagnetic communication. Autonomous systems in these environments are required to perform highly-complex tas ...

This program will develop a communication-less solution to decentralized control and task coordination for multi-agent systems (MAS). Reducing the operational burden of MAS swarms on human operators will greatly improve the capability of spacecraft constellations and distant planetary explorations. The proposed solution would guide the MAS towards a cost minimized set of actions by performing grad ...

The innovative methodologies proposed in this STTR Phase 1 project will enhance Loci-STREAM which is a high performance, high fidelity simulation tool already being used at NASA for a variety of CFD applications. This project will address critical needs in order to enable fast and accurate simulations of liquid space propulsion systems (using propellants such as LOX, LCH4, RP-1, LH2, etc.). The pr ...

Launch vehicles experience extreme acoustic loads during liftoff driven by the interaction of rocket plumes and plume-generated acoustic waves with ground structures. Currently employed predictive capabilities to model the complex turbulent plume physics are too dissipative to accurately resolve the propagation of acoustic waves throughout the launch environment. Higher fidelity liftoff acoustic a ...

The proposed solution exploits recent advances in computer vision to conceive of a single-camera + gyro + accelerometer vision-based navigation solution such that the processing will be lightweight (requiring only a single optical flow sample per frame). Known landmarks (natural or artificial) will have absolute positions known to planetary exploration worker robots. The worker robot can identif ...

Advances in structured heterogeneity together with nanomaterials tailoring has made it possible to create thermoelectrics using high temperature, polymer composites. While such thermoelectrics do not have the capability to approach the efficiency of top performing ceramic modules such as BiTe, they do provide two unique aspects of use in energy scavenging: the ability to cover large areas easily, ...

Small and micro-spacecrafts require the efficient, micro-propulsion systems. Chemical micro-propulsion is best suited for use as primary thrust, orbital insertion and attitude control because of its high energy density. When grouped into arrays for larger thrust applications, micro-propulsion devices provide high propulsive flexibility or can be used as igniters. The proposed effort will focus ...

This proposal offers to provide NASA with an automatic mesh generator for the simulation of aerodynamic flows using Reynolds-Averages Navier-Stokes (RANS) models. The tools will be capable of generating high-quality, highly-stretched (anisotropic) grids in boundary layer regions and transition smoothly to inviscid flow regions even in an adaptive context. The objective of the work is to offer a un ...

The proposed innovation utilizes carbon nanotubes (CNTs) coated with pseudo-capacitive MnO2 material as nano-composite electrode and ionic electrolyte for the construction of ultracapacitors. This novel approach of using nano-structured CNTs architectures provides high surface area of attachment of MnO2 nano-particles to maximize the charge efficiency and power capacity and to reduce series resist ...
