Presentation on theme: "An Introduction to Water Rockets. At first, I just built rockets that had no recovery system at all, this makes things simple if the rocket survives the."— Presentation transcript:
What are the problems and how can I fix it, that is what I thought about all the time. In the picture above the fin material was not stiff enough for the size of the rocket and was fluttering in flight. Altitude is greatly reduced when that happens.
Another problem I had was with the parachute lines twisting, using a fishing swivel helped this greatly.
The next few pictures are of a Pitsco Saber rocket I built from a kit. An air chamber that was held squeezed down by vacuum and released slowly when the flap on the rocket came off was used for parachute deployment. This worked well for several launches and then it failed for two launches. It was a simple method for parachute deployment if only it was always reliable.
I taped the bottle when painting to create a water level indicator.
