NASA Connection

Why is it important to make the launch vehicle as lightweight as possible? [Type responses in the chat]

Background NASA uses lightweight, strong materials for launch vehicles Focus on thrust structures NASA’s history of testing rockets

Saturn V Space Shuttle Ares I Ares V

Saturn V First Stage

Saturn V Second Stage

Saturn V Third Stage

External Tank (ET) 2 Solid Rocket Boosters (SRB) Orbiter The whole system is called the Space Shuttle. STS-133 (Space Transportation System)

Space Shuttle Flight

Rocket Staging Which was used for Apollo? Which did the Space Shuttle use?

Space Launch System NASA is moving forward with the development of the SLS, an advanced heavy-lift vehicle that will provide a new national capability for human exploration beyond Earth’s orbit.

Human Factors This full scale model of a portion of a rocket design that was built at Marshall Space Flight Center to see how the pieces would fit together. When this rocket needs servicing, will a human be able to get to the appropriate place safely and without damaging the parts of the rocket? This is one of the stages of the rocket.

The Lesson in Detail

Thrust Structures

What are some ways NASA engineers could make a launch vehicle as lightweight as possible? [Type responses in the chat]

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

The Design Challenge

Engineering Design Process

Design and Results Sheets

Design Constraints Use only the specified materials Must be taller than 5 centimeters (2 inches) Must allow space in the center for fuel lines and valves (represented by 35mm-film canister without lid)

Launch to orbit = propelling a 1-liter bottle of water approximately 1 meter into the air Definition:

Classroom Sessions Session 1: Introducing the Challenge and Getting Started Session 2: Design 1 Sessions 3 and 4: Designs 2, 3, 4, 5 Session 5: Storyboard/Poster Session 6: Student Presentations

Comparing Rockets

If it costs $10,000 to lift a pound (half a kilogram) of payload into orbit, calculate the cost of sending yourself into space. (Sharing is optional)

ModificationsandExtensions

Customizations Allow modifications of cardboard Allow repairs Increase the rocket mass Design with alternative materials Limit designs by cost (budget)

Keep inspiring your students. NASA always needs workers interested in Science, Technology, Engineering and Mathematics.
