Thermal stability is an important indicator to measure the reliability of aerospace equipment, and space thermal environment complex, commonly used analysis software for ground equipment can no longer meet needs. For this reason, based on design SINDA/FLUINT, taking a spacecraft as research object, balance equation first established. Then, use desktop establish numerical model, SINDA/FLUINT sol...

A Satellite Attitude Dynamics Simulator (SADS) has been developed to facilitate the research and development of spacecraft flight attitude control software at the Naval Postgraduate School in Monterey, CA. The simulator provides a real-time 3 degree of freedom (3DOF) synthetic spacecraft hardware-in-the-loop environment, that includes realistic angular motions, sensor-effector delays, and contr...

The spacecraft equipment layout optimization design (SELOD) problems with complicated performance constraints and diversity are studied in this paper. previous literature uses the gradient-based algorithm to obtain optimized non-overlap schemes from randomly initialized cases effectively. However, these local optimal solutions too difficult jump out of their current relative geometry relationsh...

Prognostic technology uses a series of algorithms, combined forms a prognostic-based inference engine (PBIE) for the identification of deterministic behavior embedded in completely normal appearing telemetry from fully functional equipment. The algorithms used to define normal behavior in the PBIE from which deterministic behavior is identified can be adapted to quantify normal spacecraft telem...

This paper discusses ergonomics research using remotely situated video cameras in spacecraft. Two prototype studies of crewmembers working in the micro-G environments aboard the first two flights of Spacelab are described. Various aspects of crew restraint, stabilization, manipulation of controls, and mobilization were observed, operationally defined, and quantified by observing videotaped scen...
