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.

UNmanned Antares Rocket Explodes seconds after launch

This is a pretty spectacular malfunction. Good thing this was unmanned. No reports of injuries, just a big mess.

Back in July we drove by the ATK buildings in Utah. The engine test building was really cool. Too bad they weren't testing at the time!
It will be interesting to hear what component failed and caused them to abort. Aren't they using 50 year old motors?

The motors are from the Soviet N1 moon rocket.

The same one that exploded on every test launch.

"preliminary analysis pointed to a failure of a turbopump" Sounds like OSC is ready to abandon the AJ26 engines. Of course their customers would likely demand it. This puts them out of service to the ISS for at least 2 years.

There was some initial reporting that the turbopump may have ingested a foreign object, but these guys likely took precautions like adding baffles or filters to the fuel lines to prevent this type of thing, so the failure of the pump could be the real answer.

But why turbopumps? How about they pressurise the chambers to 10,000 psi (yes,they are) ? Then the turbopumps wont be needed. They would only need a regulator to control burn rate, right? They were using old engines anyway.

And if they are already using this design, will anyone cite the name of the rocket?

Thanks
