NASA wants to develop new relative navigation methods and sensors for autonomous rendezvous and docking, with a minimum relative navigation sensor suite addressing spacecraft-to-spacecraft ranges of 100 kilometers through docking, including relative attitude control during the final 100 meters of the approach. This proposal represents an opportunity to leverage an on-going program. The Video Guida ...

A lidar laser transmitter useful for profiling of clouds, aerosols, and differential absorption measurements of atmospheric trace constituents such as carbon dioxide, water vapor, and ozone is proposed. The proposed laser transmitter is based on a master tunable external cavity diode laser (ECDL) used to injection lock a series of free running laser diodes (FRLD's). The FRDL's amplify the injected ...

Operations on the International Space Station (ISS) currently require 24/7 support from Ground Operations personnel due to the relatively new establishment of that facility on orbit. As ISS activities become commonplace, the need for continuous monitoring by Ground Operations will wane. Automated and teleoperated systems as well as ISS crew experience will allow the Flight Controllers to leave the ...

Plans to distribute International Space Station (ISS) downlink video to Remote Principle Investigators (RPI) requires Internet 2/Abilene connections, multicast network capability, and 4 Mbps+ bandwidth capacity. Our goal is to make ISS downlink video much more accessible to RPI?s, NASA centers, and education/public outreach sites by converting the downlink video to lower resolutions, unicast, and ...

CFD Research Corporation (CFDRC) and the University of Wisconsin-Madison (UWM) have teamed in this STTR project to develop and validate an atomization/spray module that more accurately models many of the complex physical processes involved in spray combustion. Accurate predictions of atomization/spray characteristics are vital to successful analyses of combustion systems for gas turbine, rocket, a ...

A computational technique that utilizes an innovative tightly coupled combination of CFD, 6-DoF and blast wave simulation methods is proposed for the analysis of crew escape systems for future launch vehicles. An existing high-fidelity simulation program, well validated for military crew escape systems, will be leveraged to meet the challenges of simulating escape system operation for launch abort ...

Combustion Large Eddy Simulation (LES) is a vastly improved method of modeling turbulent-combustion in gas turbine combustors, and will provide improved emissions/instability prediction capability of UEET combustors. It is widely recognized that one of the best subgrid turbulence-combustion models is the Linear Eddy Mixing (LEM) model with multi-step reactions. However, this model is not commonly ...

The overall objective of this project is to develop a drag and drop, component library (fluidic lego) based, system simulation and optimization software for entire lab-on-chip systems. Current approaches for biochip system design are either very inefficient (trial-and-error based) or time-consuming (high-fidelity simulation-based). The proposed tool will benefit the biochip community by tremendous ...

Determining an effective structural design of a launch vehicle is critical to both mission success and crew safety. In order to evaluate the adequacy of a launch vehicle?s structural design, the ascent loads experienced by the vehicle must be determined. Computation of the ascent loads is a complex, multi-disciplined undertaking that involves an assessment of both natural and induced environments. ...
