Gases trapped in the propellant feed lines of space-based rocket engines due to cryogenic propellant boil-off or pressurant ingestion can result in poor combustion efficiencies, combustion instabilities, or long startup transients. To assist NASA in the use of the high performing liquid oxygen propellant combinations in space engines, IN Space proposes to investigate the feasibility of an innovat ...

A robotic sample management device and system for the exposure of biological and material specimens to heavy ion beams of the NASA Space Radiation Laboratory (NSRL) and other irradiation venues is proposed by SHOT, Inc. Full and efficient utilization of NSRL requires the automation of precise sample positioning and sample exchange that is otherwise performed manually at the cost of hours of beam ...

THIS EFFORT IS INTENDED TO DEMONSTRATE THAT A C.T.I. REVERSE ENGINEERINGMETHODOLOGY CAN DEVELOP COMPREHENSIVE SPECIFICATION TREES, REQUIREMENTS DOCUMENTS AND DESIGN SPECIFICATIONS USING EXISTING CODE, COMMENTS, AND THE AVAILABLE DOCUMENTATION OF A ...

RECENT TECHNICAL ADVANCEMENTS IN THE SEMICONDUCTOR DEVICE AND POWER CONDITIONING TECHNOLOGIES HAVE LED TO SUBSTANTIAL IMPROVEMENTS IN TERMS OF SIZE, WEIGHT, EFFICIENCY AND POWER QUALITY OF THE POWER CONDITIONING EQUIPMENT WHICH IS BEING CONSIDERED FOR SPACE APPLICATIONS. WITH THESE ADVANCEMENTS COMES AN ABUNDANCE OF DESIGN CHOICES AND INCREASED DEGREES OF FREEDOM WITH RESPECT TO POWER SYSTEM CONTR ...

ONE PROMISING APPROACH TO THE DEVELOPMENT OF GENERALIZED MODELS OF COMMUNICATION SYSTEMS IS COMPOSITION OF MODELS FROM COMPONENT MODEL MODULES. IN THIS APPROACH, MODELS OF INDIVIDUAL SYSTEM COMPONENTS ARE DEVELOPED AND SUBSEQUENTLY LINKED INTO A MODEL BY MODEL COMPOSITION SOFTWARE. AN INTEGRATED SOFTWARE ENVIRONMENT SUPPORTS THIS TECHNOLOGY BY MANAGING A MODELBASE OF MODEL MODULES PROVIDING FOR TH ...
