Airfoil Launch
Objective To build an airfoil, out of paper provided, which will be powered by a standard balloon (provided). This paper airfoil will be launched from a ramp
Purpose To investigate the physics of flight.
Participants Teams of up to four.
Materials 2 sheets of standard 8 1/2" X 14" paper - balloons, drinking straw, glue, tape - scissors and a launching ramp.
Rules
  1. The maximum dimensions for the balloons are approximately 50 cm long; 10 cm diameter when filled with air.
  2. No materials other than those provided may be used.
  3. The balloon is the only legal means for providing thrust.
  4. Any release mechanisms - relaying the airfoil from the balloon and drinking straw are at the discretion of the designer.
  5. Launch from a table top 1 m high.
Judging
  1. There are two parts to the event:
  2. First Launch (distance) - the greatest distance covered in a straight line.
  3. Second Launch (mass) - the airfoil that can carry the greatest mass for a minimum distance of 10 metres.
  4. The same airfoil must be used for both events.
