Water Rocket Launch to 2,269 ft (691m) - Personal Record!

This video covers a couple of Dark Shadow flights that set our new personal altitude records at the recent Thunda 2019 high power rocket launch event.
Launch #1 2:30 - 2,066 feet (630m)
Launch #2 5:37 - 2,269 feet (691m)
Thanks to LCOs: Bryce Chanes and Charlie Rosenfield.

I fondly rememer those toy rockets I had as a kid that used air & vvater & pressure , they vvere fun but didnt go much more than 100 ft & the plastic they vvere made from tended to break easily. I later graduated to model rockets using solid engines vvhich I do on rare occaisions ( vvhen my nephevv is around ) still launch them. Your rocket is beautifull & solidly designed & such a high launch is an amazing feat . TY for discussing its developement & shovving the launch as its kindled a smallbut grovving desire to get back into sucha fun & revvarding hobby. I vvish you even greater success in future launches & TY for an interesting & fun video. Lastly the vievv from on board the rocket vvas spectacular ! Keep up the great vvork !!!

Love your work George. Looking forward to seeing the 1000 psi performance.

[@AirCommandRockets]

Thanks Craig. We hope it survives the pressure and acceleration. :)

Greetings from Brazil to all. 2:54 wow !!! Incredible too. Yeah, thanks George !!! A little more and hit the moon !!! Ah, it's the parachute ... awesome. Congratulations on the achievement. Success.

Cheers Le Z :)

[@marcelwaldner8302]

Wow, Congrats to your new personal record 👍

[@AirCommandRockets]

Cheers. :)

[@michaeljacquesson4278]

i'm launching water rockets (in france) with my 8 years old son too. i don't have same level, i use soda bottles for 200ft max altitude at 50 psi... it's very impressive to see your result.

[@SterremanWillie]

One could hear the commentator being just as excited as us fans! The symphony of Ohoooo's from the crowd said it all! Congratulations on the record!

[@AirCommandRockets]

Thank you Willie. :)

[@grahammercer6630]

Awesome George, well done to you and the team

[@AirCommandRockets]

Thanks Graham. :)

[@RaketfuedrocketsDeutschland]

Congratulations to this two amazing launches! Dark Shadow is truly a very powerful rocket, and going over 1000psi will push the limits even further. It's also interesting to see how you were able to improve your parachute systems in size and weight. Keep the amazing work up!

[@AirCommandRockets]

Thanks Julian. :) We'll cover the details of the Horizon deployment mechanism in an upcoming episode of the Horizon series, and we'll compare it to the previous ones in a bit more detail.

[@dc54321x]

Another top quality video. Congratulations on yet another PB! It'll be interesting to see the maximum altitude achievable by Dark Shadow

[@AirCommandRockets]

Thanks David. We're hoping to try again at the next Mullaley launch. Do we have any ideas when this is likely to happen?

[@tcsyme]

Congratulations George, what a fantastic achievement!

[@francescopaolo8389]

Congratulations, can’t wait to see the complete horizon rocket!!!

[@TheAnimaniacarts]

Congratulations from Vienna / Austria George!

[@spacemanmat]

Well done George.

Cheers SpaceMan :)

Great shot from inside the rocket!

[@picknikbasket]

Great stuff, George, congratulations!

[@AirCommandRockets]

Cheers for that :)

[@IntRocketLaunch]

Amazing launch!

[@Allan_aka_RocKITEman]

At 02:52 in this video: *"Where did it go?"* Judging by the video I would say: *_"UP"_* 😝😝😝😝😝😝😝

[@AirCommandRockets]

I concur with that analysis. :)

Nice work. Well done. Congratulation!

[@WATERROCKETSCLUB]

Well done! Congratulations on your new record! Probably the height could have been more if it were not for this annoying breakdown of the pad. (We'll have to remember the university course: "Mechanics of a deformable solid body");)))). Looking forward to new videos!

[@AirCommandRockets]

Thanks Water Rockets Club. We'll have another close look on the next launch to see if the rocket is still impacting the guide rail. We're not sure what sort of an affect the guide rail smack has on the altitude.

[@Enlight_Entertain]

Wow congratulations on your record 👏 Im from Victoria 🤠

[@AirCommandRockets]

Cheers :)

[@cosmo2002]

Congratulations! Just to be more visible for the crowd, it's possible to add a small smoke flare or something like that?

[@AirCommandRockets]

You could, but the point wasn't to be more visible, it was to get the performance. Hybrids have a similar issue in that they produce very little smoke.

[@w4rlockkk]

Wow awesome you could see the curveture of the earth

[@moiperso3716]

Super cool 👏👍

[@herzigfrancois5444]

Very nice launch's George and very good job !! Congratulations !

[@AirCommandRockets]

Merci François :)

[@DoRC]

Looks like about a 3 second quarter mile time. Not too bad:)

[@IAmDeepSpace]

Fun!

[@Allan_aka_RocKITEman]

@Air Command Rockers >>> The slomo footage starting at 03:16 in this video seems to show the water exhaust 'popping' just after the rocket starts to ascend. Is that _normal?_ Also: Do you use compressed ambient air to pressurize your rockets? Or maybe nitrogen? The scuba tanks tells me you use ambient air, but have you ever tried nitrogen or anything else? If so I was curious what you found out by using it? {Thanks in advance!}

[@AirCommandRockets]

The pop just after launch is the launch tube emerging from the nozzle and the water starts to come out. We use just regular air in our rockets. It's just air from a regular scuba tank that was filled with a regular compressor. We have not tried any other gases, though CO2 would give better results.

i have a challenge try to reach 800m with foam and wáter and 700m with wáter only

[@matthewday7565]

Is the optimum air to water ratio the same whatever the pressure?

[@AirCommandRockets]

Pretty much. It does vary slightly but not much.

[@gencu9730]

Heyyy I went to the nsw rocketry club and I saw u

[@AirCommandRockets]

Cool. Will you be coming back for the next launch?

[@gencu9730]

Air Command Rockets yeh I bought a rocket and flew it but it got lost so I built myself a much better and bigger rocket

[@russedmonds227]

Fantastic work. Did you go to one altimeter instead of two?

[@AirCommandRockets]

Cheers Russ. We went with the one altimeter this time, as we are not sure when the rocket is going to fail and we don't want to lose 2 altimeters on the one flight/crash/explosion. We know the altimeter gives us fairly accurate readings and because it logs the entire flight we can see if there were any spurious altitude readings.

[@russedmonds227]

Thanks for the reply and again great work.

[@martindssing1206]

When will Part 10 be uploaded?

[@AirCommandRockets]

Editing part 10 right now. I have about 3 hours of video I need to edit down to about 10 minutes. Will upload probably next week.

[@michaelwni]

isn't that a world record??

[@AirCommandRockets]

I believe University of Capetown currently holds the altitude record. kzbin.info/www/bejne/ipOYd4moesp4a5I

Nice Only cultured people will get this (691m)
