Ablative Shield Challenge

Requirements, Limits, and Constraints

  • Create a Thermal Protection System (TPS) out of only the supplies available.
  • You have a budget of 100 Credits.  If you go over your budget, your TPS will be disqualified.
  • The abilities of each design will be tested with a blowtorch.
  • A layered design model must be drawn and approved by the Engineering Specialists (AKA: teachers) before any supplies are purchased.                
  • The TPS must be NO THICKER than 1 cm.                                        
  • The TPS must weigh LESS THAN 45 grams.                                                
  • The TPS will be secured to the test stand using clamps and the “Eggstronaut” will be placed BEHIND it on the stand, touching the TPS.
  • The TPS must protect their “Eggstronaut” for 3 minutes from the blowtorch (approximately 3500oF)                                
  •  “Eggstronauts” will then be removed from the stand and cracked to see how much damage was done by the heat. The goal is to have a completely raw “Eggstronaut”.

Layered Design Model

Side-View of Shield:  Be sure to label all materials used.  Also identify which side will face the blowtorch and which side will be touching the “Eggstronaut”.

Description of Shield:  Be sure to identify amounts of all materials used.
