Water Rocket flies to 1752 feet (534m)

[@dredrotten]

Oh Wow that was so cool,those camera shots going up are incredible.Good on you blokes for doing a good job.

[@leokimvideo]

Loved this, not sure how I found it because I was looking at rocket explosions than this. I used to use distress flare motors as rockets back when the biggest motor was a D. But sadly these days laws have really tightened up in relation to expire distress flares. The good old fun days are now over. Having fun now is a criminal activity. I was worried your first flight day was Friday 13! Be careful with pressure vessels, sadly I know a few people in my line of work who have nearly been killed by them failing. There is absolutely no warning of failure.

[@AirCommandRockets]

+leokimvideo Thanks. We thought Friday the 13th was more than appropriate to try something new :) I couldn't agree more about the dangers of pressure chambers. They look so innocent just sitting there, but they are very dangerous especially at these pressures. This is why we stand a long way back and can depressurise them remotely if needed. We have had quite a few fail over the years. kzbin.info/www/bejne/mYOyh6qgfr-UZ7M

It is the launch amazing . I was overwhelmed by the grandeur of the technical capabilities and results .

[@RaketfuedrocketsDeutschland]

These are actually one of the most impressive onboard footages I've ever seen. The height looks almost incredible. You did a really good job at your build log, I just scrolled through it and was impressed by the level of detail. I'll definitely read the two pages tomorrow. It would be awesome if you could place the onboard camera in another angle so that it films a bit of the rocket itself at your next launch. Keep up your work, your rockets are getting better and better and it's truly stunning with how much precision you work. Also very good video editing. :) Cheers Julian

[@AirCommandRockets]

RaketfuedRockets Thank you Julian, we were happy with how little spin there was on the rocket. The new fin alignment jig worked really well. The angle of the video camera was intentional so it would film the horizon near the top of the frame as most of the interesting things to see are on the ground. Because the camera is in the nosecone (that's where there was room) we had limited capability of looking down the rocket without extending the lens/mirror further out into the air stream and causing more drag. I'm happy to answer questions about the build if I missed something in the build log. :)

[@nzoomed]

Never thought a water rocket could go so high!

[@rogerwhite5061]

Amazing rocket and amazing flights! Good job guys!

[@francisdavis1271]

Water rockets are "fun" but there an asymptote to performance: The velocity of the rocket vehicle is a product of the "jet" (fluid velocity) and the natural logarithm of the mass ratio. Driving up the ejection pressure does increase the fluid velocity but requires ever increasing structural capability. As a research project I have taken fluids to 12,000 to 15,000 psi - it makes a wonderful "water laser" (metal cutter) but could not get to a practical tactical velocity to accelerate the desired payload. Fluid velocity is based on Bernoulli. The Army experimented with Freon stored in liquid with limited success. The Freon did transition to gas which improved the effective jet velocity. Part of this was to reduce launch signature and gunner hazard. A fluid counter mass or "Davis" gun (patent 1914) works better as you're not tieing the payload to the structure. A possible solution for "rocket" system is a two phase flow where fluid is introduced into the gas stream and accelerated... but the plumbing has to be clever to get the sweet spot for performance. Internal ballistics of the propellant has to be clever too.

[@AirCommandRockets]

One way to introduce 2 phase flow is by creating foam inside the rocket. From experience this gives a nice boost in performance.

[@Migsterification]

Very impressive build and performance! Enjoyed your video very much!

[@AirCommandRockets]

Thanks Migsterification :)

[@LK-pc4sq]

The accumulators on our Sikirsky Ch-3e would be compressed from 1,500-3,000 PSI after we used a hand pump and 200 pumps to compress it to that amount of pressure. Mind you, once the accumulator is depleted spinning up the APU, the hydralic pump from the APU recharges the accumulator. It would make a excellent engine for one of these rockets.

[@alphabeticalor]

+Lorin K Maybe. It releases the pressure a lot more slowly in that system. No telling if it could produce a decent nozzle velocity. If it would just be a pressure vessel hooked to the main engine body, you'd have to make the engine body strong enough to hold that pressure, so you wouldn't bother with the extra pressure vessel.

[@polyscient]

Wonderful stable onboard camera footage with very little spin! Very impressive acceleration. Great engineering and build guys.

Hi AirCommand Rockets, as always, great launches and great presentation, you guys are second to none in the world when it comes to Water Rockets. It was great to catch up and witness the flights first hand at THUNDA Down Under 2015.

[@AirCommandRockets]

David Bell Thanks Dave, it was great catching up with you at Thunda. :) Your flights at Thunda weren't too shabby either. How many thousands of Ns did you end up burning again!?! And that L3 flight was done in awesome style! :)

[@MrBellda]

AirCommandRockets Hi mate, thanks, only 30,483 Ns (49% O), I had planned on upwards of 85,000 Ns but just ran out of time, next time I will bring along a support team :-) My major issue was that when launching the Patriot on a cluster (which i did twice, I had planned to launch a total of 5 clustered flights), the central inboard motor's exhaust would melt the outboard motors plastic thrust rings (CTI 38mm) resulting in a 6 hr turn around time between flights as the melted thrust rings would mold themselves to the threads of the GLR Slimline Retainers and had to be mechanically removed... :-(

Todd Hampson Thanks very much for the nice words Todd. :) This was a fun rocket to build, although testing and flying at the higher pressures sure can get a little scary. I'm not looking forward to the day when it decides to let go. :)

[@kamelitotoe592]

If you use redbull instead of water you can go higher

[@leteveryoneknow]

If you use alcohol and light it up, you will actually go higher

[@jashencloma7690]

+leteveryoneknow great idea as they launch the rocket the alcohol exiting through the valve will be ignited by a electronic ignition system

Heat the water up to boiling and then try it with a tiny electrolysis device in the exhaust to ignite and catalyze the propellant in flight.

[@the_disabled_gamer2832]

You should install a G-Meter on the rocket so you know how much vertical forces are on the rocket at liftoff etc etc.

[@ighmur]

Salted water density is around 1.19 time greater than the one of pure water. Perhaps this rocket would go 20% higher with salted water? Note that salted water viscosity is higher, one thing would be to reduce the water viscosity by heating it or by adding some additive like soap or the one that are used for the negative washing bath in photographic processing.

[@AirCommandRockets]

Higher density doesn't necessarily improve altitude. Although you produce higher thrust, you are also having to lift the higher density (heavier) liquid still in the rocket. Here is a whole video we did that looks at this very issue. kzbin.info/www/bejne/fKaWo3yfhd6SZ5o

I stumbled across this and It brought back memories of when I was young. Century model rockets were produced in my home town of Phoenix Arizona. At the time they were bigger than Estes, and higher quality. My favorite was the 3 stage Apollo rocket. Mine had 8 successful launches but on her 9th I forgot to check the fittings and she blew up before she cleared the rail. Devastating. The only water rockets at that time were the reddish ones that you pumped up with your foot and at best went 50 foot. Nice to know that that people still try to improve these beautiful art

[@petethegreekre]

Really impressive, what blows my mind is the explosive acceleration. I didn't know that acceleration like that was even possible. Could it be even faster using a gas instead of a liquid, but then I guess it would be a lot more dangerous in case of an accidental explosion. Fantastic work!

I wonder if a hybrid of this and traditional rocket engines could be made. The main benefit I'm seeing from the water rocket is the acceleration, if combined with a traditional rocket motor to kick in once acceleration levels and starts to decline you would have a monster. Traditional rocket motors use alot of there fuel for the initial start and acceleration, if you bypassed all that then just kicked the motor on to continue the flight you would achieve a very high altitude.

Very impressive! Amazed that it goes through the water (with wicked acceleration) so quickly, but seems to still have thrust from remaining pressure for quite a while. I would think (guess would be the correct term) a smaller orifice which is tuned to run out of water just before air pressure would increase the acceleration time and maybe altitude. The slow motion led me to this theory. You are the pro and this thing rocks!

The fins on your rocket look tiny for a rocket of that size. The straightness in which it flies is a testament to your capabilities as a builder. There are many places something can go wrong during a rocket's planned flight but you make it look easy. I commend you, you should feel proud.

[@AirCommandRockets]

Thanks for the nice words +MrKillb8 :) The fins are actually a little oversize for this rocket, the simulator-predicted ideal fin size just didn't look right so we made them a little bigger. We used a new fin alignment jig for this rocket too so we were happy with the results.

[@castoresnegros]

So !! IT is using just water in the first seconds only?

[@AirCommandRockets]

+graciano b During the very first part of the flight (after it leaves the launch tube) the air pressure pushes the water out this takes just over 100ms, and then the rest of the air comes out in another approximately 100ms. The rest of the flight is just coasting.

[@Mythricia1988]

+AirCommandRockets Having some difficulties understanding the benefit of adding the water in the first place - if there is one. Considering how incompressible water generally is, wouldn't you get more velocity from the rocket by simply filling it with air to replace the volume the water is taking up? So basically running it as a compressed air rocket... I get that water is heavier, and the rocket moves by throwing mass out the nozzle, as all rockets do, but since there's no chemical reaction to release energy here (only mechanical energy), I just can't figure out how the water rocket would be better. Surely the fact the water is heavier also makes it more difficult to push out, thereby negating the benefit of ... well, the water being heavier? I'm sure there's more to it, but my poorly educated self can't figure it out! :)

[@AirCommandRockets]

+Mythricia No, actually it's a great question. Thrust is all about 'throwing' a mass in one direction to make the rocket go in the other direction. The heavier the mass and the faster you throw it the more thrust you have. Air is compressible and so can store a lot of energy, but is also very light. So although it can leave the nozzle at sonic speed it doesn't carry a lot of mass with it. Water being essentially incompressible cannot store a lot of energy, but it does have a lot of mass. So in a water rocket you use the stored energy of the air to push the heavy water out the nozzle. There is of course a trade-off between the amount of air and water you use. As it turns out the optimal ratio of water to air is around 1/3 water, and 2/3 should be air. For some more information please see: www.aircommandrockets.com/water.htm

[@Mythricia1988]

AirCommandRockets That explains it a bit, I'll be sure to read more following that link. Thank you!

[@AirCommandRockets]

+Mythricia I guess another way to look at it would be the difference in recoil you would feel when you fire an actual bullet from a gun vs a blank both with the same charge.
