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

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.
