Design and Construction

Today Ricky and I started to build our rocket. We attached fins. Also we made our blueprint for our design. Sometime today Ricky should be posting our blueprint on the blog.

This is the current blueprint. Not much is on it, so the following bullet points will demonstrate the purposes.

• The parabola cone will bring the least amount of drag. Currently we are aiming for a 3-4 inch cone in height with the same diameter as the bottle.
• The "teardrop" body is designed aerodynamically and will also carry less chance for drag. The diameter is about 38 cm and curves into a 9.5 cm end.
• Our fins (there are 3) are made to fit the curved part of our body. The fins are made of thick cardboard and are placed at the lowest spot possible on the body for stabilization and lowering the center of gravity.
• We have a rough estimate on our water amount. We want to have a little more than 1/3 of the bodys' volume filled with water: more will weigh it down and less will give it less "liquid fuel".
• Our design is still in the making but when we are finished, the R.R.R. will be a huge success in height and distance.
