While you are discussing nozzles, here is what I have done in the past: Rather than a screw on nozzle I have glued on the Gardena style nozzles. However to get...
We didnt get any testing done this weekend but we did manage to build a new rear wing for the rocket car. The logic of using a rear wing is to provide more...
Does the steering problems occur during the start or at speed? During thrust or during the runout? Would a short ( 1m) guide rod help to steer durring the...
... Under low thrust it doesnt appear .. car runs pretty straight. Under high thrust it just steers off to the left or right ... High thrust phase ... I dont...
Todd, A friend of mine that drove funny car dragsters said that after he hit second gear the front wheels were off the ground and the steering wheel was...
The bellows air system worked well for about 7 launches and then crashed the next two. I taped the remains together and then the parachute deployed early the...
A friend of mine that drove funny car dragsters said that after he hit second gear the front wheels were off the ground and the steering wheel was useless. He...
After about our 4th attempt, we have finally managed to get a smaller diamter nozzle to work properly. We need these to even out the thrust on our water rocket...
The list was a little quiet this week ... everyone busy I guess :) We had a launch day on the weekend to try out the new rear wing and 6mm nozzle. Good news is...
Hi Everybody, Been busy on some other projects (home made audio-speakers) lately so launching was delayed, mostly also due to horrible weather, good conditions...
Very nice update on the water rocket car experiments Todd! Boy 96m so close too. :) When you switch the disks in your nozzle to restrict the flow, have you...
Very nice find Ruben. :) An HD camera at that weight is very nice. I tried looking up a price for it, but was unable to find one. Is it a recent release? There...
Hi Ruben, We noticed that you were interested in seeing some HD footage taken from a water Rocket. We hope to satisfy your curiosity by inviting you to check...
Hi US WR, Do you guys have a name, John or Chris or whatever? I like the 3000 project a lot, great nosecone with payload section! Despite being HD the camera...
Hi Guys, We had a good flight day on Sunday. It was good to get something off the ground again. :) We flew a modified rocket that gave us a different ...
Great video! I could see how the foam generation changes the thrust. Unfortunatly, the foam is formed and then it is real hard to see what happens. But, you...
Hi, I loved pauls website - it was really inspirational, i dont know if anyone has a backup or if paul himself has a backup or has relocated it now? Thanks, ...
Tested three more samples of PL400 today. Mixed results... Sample A failed somewhere between 18.8 and 22 kg. The water tank was full (18.8 L), so I unhooked...
Hi George, Great stuff... I was thinking about doing something similar for my tumbler efforts... Since my camera only weighs 18 grams i' m going to do...
Thanks Mike, :) You are right, we need to fly this without foam to get a better view of what the water is doing. I was going to add food colouring, but forgot...
Hi Ruben, that sounds like a great idea. We all assume that a deployment system behaves a certain way in flight, but being able to see really how the mechanism...
Hi George, Did you notice in the slow motion landing that the rocket actually bends into a curve hitting the ground and bounces back into shape as it falls...
Thanks for those glue results Henning. It seems like the PL400 is a pretty good glue if it was still able to hold 22.5Kg. Did that sample have the same bubble...
Hi Will, I agree, as was mentioned in the earlier thread (http://groups.yahoo.com/group/water-rockets/message/9901) it's sad to see such a great site gone. I...
... I emailed him shortly after I discovered the site had closed. No reply, I'm afraid. His email address is paul-grosse AT ntlworld.com and you must put AG7Y...
We have completed some more testing with reduced nozzle inserts and have the results posted on our website. We tested 6mm, 7mm, 8mm and 9mm nozzles and also an...
... These were all loaded during cure, and I didn't observe the same air bubbles. The samples are the same strips used for the previous test, and I didn't...
