Ultimate Thermal Protective System Challenge: Engineering for Heat Resilience

Join Lisa Brown, NASA Aerospace Education Specialist, in creating a Thermal Protective System (TPS) capable of withstanding temperatures up to 1650°C. Understand the principles of heat transfer, conduction, convection, and radiation to design and test the TPS using specified materials. Build a heat-resistant model and document the results in a comprehensive report.

  1. Engineering Challenge:Thermal Protective System Lisa Brown Aerospace Education Specialist NASA-Johnson Space Center

  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. Other TPS Systems

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

  6. Specific Heat • the amount of heat necessary to move 1.00 gram of a substance 1.00 °C • Note the two important factors: 1) It's 1.00 gram of a substance2) and it moves 1.00 °C

  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.

  9. The Model

  10. The Test

  11. The Report
