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.

Introducing Ascension III

This forum is for new members to introduce themselves and tell us how they got started in water rocketry.

Introducing Ascension III

Post by Ascension III » Mon Sep 14, 2015 9:56 am

Hi everyone,

We are a team from the University of Cape Town Industrial CFD Research Group. We have been designing, building and testing high powered water rockets since 2013. Over the past few years our designs having been improving and we are excited to find the limits of water rocketry!

Ascension III is our latest water rocket which we launched last month on the 26th August 2015. We are going to filing for the official Class A world record shortly as our average altitude exceeded 623m set by the X-12.

We are so glad to be part of this community!

:W to the forum!
And USWR finally has another team in his league.
Don't forget to register as a WRA2 member! I think that that is nescessary to file for an official record, but I'm not shure.

Looking very good. It's been so long since we had a submission. I need to take some time to digest all this new info!

Hey there,
welcome to the forum!
It would be interesting to learn more about your rockets and your team.
Do you have a website or YouTube channel?

Thanks Spaceman Spiff!

Hi Julian, Thanks for the welcome. We don't have a website, but are in progress with our YouTube channel. Will let you know when it is operational :D

We have written a report which briefly documents our project if you would like to take a look. It is attached.

For some reason it won't upload as an attachment SC:

Anyways you can see it in the "Water rocket world record submissions" folder in the "2723 ft (830m) Class A record discussion" topic.

I must ask, as I am looking for a good one, what altimeter did your team use? The launchpad alTImeter is great, but it is rather large.

We're no WRA2 members right now, so we have no access to this thread. :/
If you want, you can send us the report at Raketfued@gmx.de.
Cheers

skysaber89,

See here: viewtopic.php?f=5&t=2805 for a stripped down version of the AlTImeter. If you're up for a little soldering it's not too bad to build and should fit inside "most" water rockets...

Hi Skysaber89,

We used the Altus Metrum TeleMetrum altimeter. It is really an amazing altimeter. Its the best we have used and has GPS. It is quite pricey though, but for high powered rockets they are worth it for their ease of use, accuracy and light weight.

Well you always could fill out the membership application:

http://www.wra2.org/WRA2_Membership_Application.php

That way you could participate in the peer review and vote on the new record submission that will be held shortly!
