  1. R O C K E T S Company Name: New Aerospace Corporation Team Name: R.O.F.L. Presenters: Christopher Herrman, Abel Tachiri, Rohan Desai Presented to: UTA Access to Engineering camp 6/10/2011

  2. Presentation Outline • History of Rockets • Forces Acting on a Rocket in Flight • What WE Did • How it Should Work

  3. The History of Rockets • The ancient Chinese were the first to use rockets in 1232 AD. • They mainly used rockets for fire-arrows and fireworks.

  4. The History of Rockets • In 1650, Joanes de Fontana of Italy designed a surface-running rocket-powered torpedo for setting enemy ships on fire.

  5. The History of Rockets • In 1696, a Polish artillery expert, KazimierzSiemienowicz, published a series of drawings for a staged rocket.

  6. The History of Rockets • In 1961, Yuri Gagarin, a Russian cosmonaut, became the first human in space. • In 1969, Neil Armstrong was the first man on the moon.

  7. The Forces Acting on a Rocket • There are four main forces that affect a rocket namely: Lift, drag, thrust and weight(gravity)

  8. Lift • Lift acts perpendicular to the direction of motion • Lift will be acting sideways to the rocket and stabilize it

  9. Drag • Drag is when air pushes against the forward motion of the rocket. • Drag slows down an object in motion.

  10. Thrust • A force that moves an object through the air.

  11. Weight • It is the gravitational force that brings an object to the ground.

  12. Objectives • Build 2 rockets out of paper, balsa wood, and glue • One rocket should go as high as possible • The other rocket should go as far as possible

  13. Parts of our Rocket • Body Tube – The main part of the rocket. In a true model, it houses the engine, shock cord, and a parachute. • Fins – Act as feather’s on an arrow. The fins prevent the rocket from wobbling/tumbling. • Nose cone – The point of the nosecone is aerodynamic, and thus helps reduce drag. Also, in our rocket, the nosecone, helps the pressure build up.

  14. What WE Did • Dimensions of our rockets

  15. Procedures • Measure dimensions of body, then cut it out. • Fold body paper around 1in. diameter tube, gluing as you go. • Measure out a circle with .5 in. greater than the length of nose. • Fold circle into cone and glue to the rocket. • Create fins from Balsa wood sheets. • Glue fins onto rockets. • Apply glue to the entire rocket. • Dry rockets over 3-day period. • 3...2... 1... FIRE!
