  1. Project Mars Stars Daniel Vo, Yadira Nieto, ShashwatChaturvedi (AeroNTX) June 10, 2011

  2. Outline • Rockets and Their History • Aerodynamic Forces • How We Designed the Rockets • Our Expectations

  3. What is a rocket? • A rocket is a device driven forward by a force that escapes from a rear vent • Have many different purposes: fireworks, going into space, missiles, and just for fun!

  4. History of Rockets • First Rockets • Early 1200s • Used by Chinese against Mongols • Brought to West by Mongols • 1600-1900 • Newton’s 3rd Law: “Every action has equal and opposite reaction • Modern Rocketry: • Age of space travel and human exploration • Rockets also were now used heavily for warfare

  5. Aerodynamic Forces • There are four aerodynamic forces that our rockets will encounter: • These act through the center of pressure

  6. Weight • Is the mass of an object relative to the amount of gravity acting upon it

  7. Thrust • Thrust is the force which moves the rocket through the air, and through space • In our case we are using air to provide our thrust • Is also the force which balances out the object’s weight

  8. Lift • Lift is a side force that is used to stabilize and control the direction of the rocket’s flight • Is usually much lower than the amount of drag on a rocket

  9. Drag • Drag is the resistance to the object while it’s moving

  10. Problems • Our group needed to design two rockets using: • Paper • Balsa Wood • Glue • One needed to achieve a high altitude • The other needed to achieve a long range

  11. Construction of Rockets • We used a NASA rocket simulator to come up with the best dimensions for our rocket

  12. Final Dimensions • Based on the simulator we came up with these dimensions • Altitude • Nose: Length is 2.5 in., Diameter is 1 in. • Body: Length is 11 in., Width is 1 in. • Fins: 3, Length is 2.5 in., Width is 1.5 in. • Range • Nose: Length is 3 in., Diameter is 1 in. • Body: Length is 11 in., Width is 1 in. • Fins: 3, Length is 2 in., Width is 1 in.

  13. Expectations Range Altitude We expect our altitude rocket to fly 140 ft. We expect our range rocket to fly 235 ft.
