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

The telemetry, tracking and control subsystem provides vital communication to and from the spacecraft TT&c is the only way to observe and to control the spacecraft's functions and condition from the ground October 29 2003 Massachusetts Institute of Technology

Why Cost Estimation? Critically important part of system design Too high- lose the contract award Too low-over-run cost plus contracts, company loss on fixed price contracts Trends Design to cost Cost as an independent variable
