Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

Schirra-1 Vehicle Test Series

Post by Trogdor » Tue Oct 16, 2007 7:27 pm

The sun came out on Friday, so we rushed the Schirra-1 vehicle to the pad for a couple quick test launches. It uses NSA recovery, with too large a parachute as you'll see, and a cable-tie launcher.

The parachute deployed prematurely on the first launch, but worked fine the second. I have made improvements to the design by adding 3 small blocks on the rocket body to keep the nosecone straight during flight.

Launch Pressure 50 psi
Load fraction ~45%
dry weight 3.8 oz.

Dedicated to Walter M. "Wally" Schirra, the coolest of all the original 7 Mercury astronauts. The only astronaut to fly in Mercury, Gemini, and Apollo space vehicles.

Promoting water-rocketry, and the adventure of science and engineering.

Beautyous flight there man!

I read what you said about the chute being too big and when I watched the video I thought that it would go into that tree! I was expecting it to get stuck!!!
