Fins tend to be the single greatest downfall of countless young rocket builders. Plastic egg halves will also fit nicely onto the "Space Needle" assembly.įins Fins are the guidance system for your rocket. This type of nose cone adds a great deal of inertial mass to the rocket and makes it really stable. The "Space Needle" This style of nose cone can be made from a spare bottle, empty paper towel roll, and a tennis ball or racket ball. One strip of tape should be enough to hold the cone on. “The Bertha” These are made by cutting the bottom off a spare bottle and attaching the top portion onto the pressure chamber. Attach to the bottle with tape or similar adhesive. You can make the cone by simply cutting a large circle out of the poster board (about a 6 inch radius). The cone is made from poster board or tag board.
“The Flounder” It is the easiest to make but lacks flight stability. The fins have been removed in the illustrations below for clarity These are only a few examples, so don't be afraid to be creative. Nose Cones Here are several types of nose cones and the methods used to make them. There are four common shapes used for nose cones:.A simple paper cone taped on top of the rocket is enough to significantly reduce the rocket's coefficient of friction.Nose cones, along with fins, are one of the most critical aerodynamic components of a rocket.For safety, rockets may not use sharp or pointed metal components or a leading surface consisting of a rigid spike Metal may be used, but may not be attached to or have direct contact with the pressure vessel at any time.Labels may be removed from the bottle but they must be presented at the safety inspection.Hot glue or super glue Even the smallest of scratches or cuts in the pressure chamber can result in an explosion.Scratch, cut or puncture the pressure chamber!.Each rocket’s pressure vessel must be made out of a single 1-liter or smaller plastic carbonated beverage bottles with a neck/nozzle opening approximately 2.2 cm inside diameter EVENT DESCRIPTION(2009): B & C-event Prior to the tournament teams will construct rockets designed to carry an Egg-O-Naut (a raw Grade A large chicken egg), stay aloft the greatest amount of time, and return to earth without breaking the egg.
