The Design Challenge

41

EngagementVideoLetter from BoldenDiscussionNASA Now: PropulsionSuggestions?

42

Thrust Structures

43

What are some ways NASA engineers could make a launch

vehicle as lightweight as possible?

44

The Challenge:Build the lightest weight thrust structure that will withstand the force of launch to orbit at least three times.

Design and Results Sheets

49

Design Constraints

• Use only the specified materials• Taller than 5 centimeters • Must have space for fuel

50

Launch to orbit = 1 meter

Modifications and

Extensions

55

Modifications

• Allow modifications using cardboard• Allow mid-test repairs • Change the rocket mass• Design with alternative materials• Limit designs by cost (budget)

56

If it costs $10,000 to lift a pound (half a kilogram) of payload into

orbit, calculate the cost of sending yourself into space.
