1. Engineering Challenge: Thermal Protective System

2. Thermal Protective System (TPS) Re-entry 1650°C (3000°F) Common TPS

3. TPS: How it works. Absorption High melting point Radiation Ceramic Tiles

4. Early Space Vehicles TPS Systems

5. Space Shuttle TPS System Light-weight Re-usable NASA uses Reinforced Carbon-Carbon (RCC), silica tiles, and blankets

6. Heat and Heat Transfer Heat is energy. Direction of heat flow. Heat source and heat sink. Conduction Convection Radiation

7. Thermal Conductivity and Heat Capacity

8. The Challenge Build a thermal protection system (TPS), using the specified materials, that protects the model for the longest possible time. Design Constraints: Use only the specified materials to construct the TPS. No glue may be used in the TPS itself No part of the TPS may touch the dowel. No part of the TPS may touch the glue.
