How to Construct a Parachute for a Water Rocket.

A great guide to backslider construction can be found in the links below. Don't design the fins so they overhang too much. Take thin cardboard and cut out 3-4 triangles. Past Results Please note that results before 2013 will include designs that allowed for parachutes. Add a paper towel tube B to the top of the capsule. For an example; if you want the diameter of the chute to be 34 inches then measure 17 inches from the center of the canopy the most pointed side of the parachute along each side, mark it and then cut it. Typically, the goal is to fly high, not sideways.

This type of nose cone can be easily weighted by removing the cap and pushing some clay into the opening before re-tightening the cap. Make sure the edges are perfectly lined up during each fold. The corrugations should be oriented vertically. Look at the shadow produced on the wall behind the rocket. Then press in onto the neck of the 1 liter bottle B for a tight compression fit. You want a nice, clean cut so the bottles can be taped together cleanly and straight.

The picture here is the older one. Thanks to Sinclair a student reading this site for suggesting this challenge. It also helps to watch other team's rockets at competitions and see how they perform. Use these lines as guides to place the fins on the bottles. Depending upon your project's mass limitations, place a golf ball sized piece of clay in the tip of the cone. So far, I have not been able to accurately connect all the segments in the middle, so after connecting all the segments, I cut off a small piece of the tip. You can also use just playdoh instead of kitty litter.

Fill the rocket with water, put thecap on, and pump air into the rocket until it blasts off. There is air space between the sides of the fin; this doubles the surface area, and makes the fins more stable. Make three fins and tape them on the rocket. When flying with restricted nozzles you tend to want to make the rocket a bit more over-stable, ie. Backsliders are the rockets that are modified so that at apogee, in stead of flipping over and heading for the ground, they float back in a higher drag configuration than a nose-dive. So that the opening of the parachute becomes a little stiffer and can also absorb or distribute the load of the lines, you can sew a line into the lower hem.

That's what make these things fun. The paper tube is glue together with contact cement and taped to the bottle and cone. Use fairly rigid scissors and cut the bottom square off of the cone. The more weight near the bottom, the more unstable your rocket will be. Use a piece of tape to close the cuts again. This will allow the mechanism to be removed from the bottle for servicing.

Using cardboard paper, construct 3 o … r 4 fins for the ship. I would not go much bigger. Generally, 3 or 4 fins are sufficient for rockets. That sometimes loosened the kitty litter enough to break free at launch, showering anyone too close that would be me with wet kitty litter. Having projects like these let educators and good parents find scientific activities they can show their children helping to create a scientifically literate public. The whole thing then just screws into either a Robinson or tornado coupling.

The system is now ready for flight. Test the parachute with a dummy weight tied to the cord. Rest the bottle on the ground and pump air into it to launch it into the air! It's very important that the marker is secure. The most successful variations of gliders will most likely deploy the wings at apogee and glide to the ground. Then sew together the two next elements as described above until you have sewn all the pairs together.

Past Bottle Rocket Information Through the years, Bottle Rocket has undergone several rule changes. For example: salt can be added to increase the density of the reaction mass resulting in a higher specific impulse. The tape will act as a hinge for the door to open. Attach the parachute C onto the extension bottle E. A rubber band is tied off to the hole next to the servo, and the parachute line is tied to the two holes made in the bottle bottom.

You can either use duct tape or use a hot glue gun. Top Designs In the history of the Rocket Corps program, several rocket building innovations have emerged as top designs in the field of water rocketry. Cover the hole in the tip of the nosecone with a cap which you can cut from a plastic egg or ball and use glue to secure it in place. We like to construct ours so that the outer aero-shell is separate from the actual mechanism itself. I had previously recommended no spin, based on a theory I read on another site - that the spin would force the water to the perimeter, keeping it from exiting the bottom.

The door hinge can be on the side or top or bottom. . This can be achieved by using a piece of string and wrapping it around the bottle and marking the string where it meets the end. The idea of this is that when the rocket launches, the air pushed the flap down. From my experience I can say that the elliptical screens with at least 6 segments work best. The bay has two holes drilled through the bottle bottom for attaching the parachute and nosecone, and a hole pattern for a servo and rubber band, which are used to secure and release the parachute. Nose cones can be made from paper, other plastic bottles or even plastic Easter eggs.
