by Andreas Hoffman Introduction This jumpstart shows you the basics of getting Scheme started, running simple programs, that the Scheme installed in the 16.410 computer lab is the Windows vers Ban On simple editing and debugging, and exiting out of Scheme. The jumpstart is oriented towards Windows installations, but can be adapted for Unix and other installations. Note Please note that this jumpstart will give you only the most rudimentary skills in Scheme

Outline Purpose of thermal control systems Review of heat transfer fundamentals Space system thermal analysis equations Models Analysis programs Thermal control sub-systems

Background An icbm with a range of 6500 miles has a stagnation temperature of 12,000%F, 2000 f hotter than the surface of the sun Calculations showed that the optimum design for structural strength, resistance to heating, and free flight stability was a long, needle nosed reentry body But it would vaporize during reentry
