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

Since our founding in 2003, we've become 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.

Need help for simplest stager

Post by RocketScientist » Mon Jul 16, 2012 4:32 am

I need help for building a multistage rocket, and I have no idea on building the staging mechanism. Gardena stagers are a bit too complicated and I don't have FTC tubing, and please don't mention anything about crushing sleeve mechanisms. Anything simpler? Please tell me step by step. Thanks.

You just eliminated the simplest systems for staging. Anything else is way more complex. You could probably cheat and not use a serial stager at all. A parallel stager would technically qualify. Just make some hooks on the side and attach parallel boosters with a larger nozzle diameter so they fall off while the core is still under thrust. That is often referred to as a 1.5 stage system.

Good idea. Like the shuttle boosters!
