This project deserves so much more attention from the public! Keep up the great work George! With the upper supports I’d almost be inclined to go with a combination of both the 2nd and 3rd option. The clips like you said would be great for keeping everything straight during first stage acceleration but then if the outer bracket wasn’t their I’d be concerned that during staging the tops of the boosters could be knocked about a lot by drag or the second stages exhaust putting a lot of extra strain on the lower supports. Though aesthetically just the 3rd option would be my favourite.
Thanks Paul, good to hear from you. :) I tend to agree that it's probably worthwhile going with options 2 and 3. One concern I have with just using the clips is that the booster segments are not supported during landing, and that could put stress on the joins further down the rocket.
An idea possibly worth considering as an alternative to a single set of clips at the top of the booster, would be to have C-profile guide rails on the insides of the three booster rockets, and mating T-rails on the sustainer. Some additional thought might have to be put into choosing the materials, to achieve both a tight fit for structural integrity and to minimize friction. EDIT: The T-rails could possibly be split into smaller tabs spread evenly on the vertical, saving some weight and to help with friction as well.
With the holding together of the booster noses, you could use the split ring, the second one you showed, where it fixes to the sides of the boosters. But make it a wing shape inwards , so it produces a compression force, holding it all together, so it can be thinner and lighter, and produce less drag
Thanks. No project is still going. Just editing next video now. We had a short break over Christmas and we did some house renovations, but have been back on Horizon for the last 3 weeks.
Hint: Do a mudmap or photograph of the connections to the old board BEFORE swapping the wires over to the new. 5 minutes of drawing can save hours of grief...👍👍👍 Do you need the old board repaired as a spare?
It all depends on how testing goes. There are always problems along the way so sometimes we have to re-do things. I am hoping that the majority of development will be done by the end of the year. Actual launches are limited by launch site accessibility (our HPR launch site) and weather co-operating on the launch day.
Finally. I think I rewatched the whole series at two times since the last eposide. Btw. are you afraid of some kind of weight asymetry because of the two chute? Or the onboard computer will balance it?
Thanks for following along. :) That's a good question. I don't think it will be that much of an issue, as we plan on putting a couple of cameras, altimeter, bigger batteries and supporting structures for those in the 3rd nosecone so it should help balance it out a little bit.
I am expecting to set up everything at the launch site and prep the rocket to take about 4 hours. We may set up the launcher the day before, and then launch the next morning when winds are calm.
@@ahmeterenbahcac7436 There is no hard and fast rule on that. A longer shock cord is better at absorbing shock when the parachute opens suddenly. But a longer shock cord weighs more and takes up more room. I would say anywhere from one length of the rocket to 5 times the length of the rocket would be normal.
It's the airflow that spills out from the underneath and around the parachute. Normally it is pretty even all around with a single chute, but the place where these flows meet from the two chutes it creates a higher pressure, and so it pushes them apart until you reach an equilibrium.
The Horizon project is no longer rocketry, it is a work of art.
Cheers Daniel :)
Yeah Daniel!!!
It's amazing the closest thing I've made to a rocket is a car a filled with deodorant and blew up
I'm proud to find this gem still in operation despite of these hard times . . .
Thank you.

George, your intervalometer is most elegant, well done! Looking forward to more videos.
Always great to see your updates!
I'm always amazed by the amount of detail and work that goes into your projects.
Thanks Laurence.
Awesome work! The rocket is coming along absolutely fantastic!

Its always a good day when Air Command Rockets uploads a Horizon Update video :)
So happy to see you posting again.
Using the three clips looks much more stable and lightweight to me than the rings
It's always a great day when I see Air command rockets video in my notification feed!
Cheers :)
That remote/time lapse device is seriously fancy.
You misspelled over-engineered.
Hi George, Love the cloud time lapse.
Awesome project. Thanks for the update. Also I love the timer. Are you able to upload the build files for it. Thanks.
I'm hoping to make these available for download from our main website. I am running a little behind with the updates there.
Air Command Rockets that would be awesome
With the holding together of the booster noses, you could use the split ring, the second one you showed, where it fixes to the sides of the boosters. But make it a wing shape inwards , so it produces a compression force, holding it all together, so it can be thinner and lighter, and produce less drag
Interesting, so it compresses inwards using aerodynamics. :)
Air Command Rockets yes, it makes itself stronger, the faster it goes
I love Rocket and want to make a rocket fly higher with the shuttle design!! Maybe in the future I will make it!
Good luck with your project!
That is impressive work !!! I hope it hasn't died due to covid

@@AirCommandRockets awesome ! Can't wait !

Do you need the old board repaired as a spare?
Yup, we did both photographs, as well as written out the connections before we started the board swap.
Information and good video
cracking on...cheers!
When do you think the rocket will be done?
It all depends on how testing goes. There are always problems along the way so sometimes we have to re-do things. I am hoping that the majority of development will be done by the end of the year. Actual launches are limited by launch site accessibility (our HPR launch site) and weather co-operating on the launch day.
@@AirCommandRockets OK, thanks
Glad you guys are still hard at work and getting stuff done! \(^_^)/
What program do you use
Finally. I think I rewatched the whole series at two times since the last eposide.

Nice
Are you thinking about launching lumpy as a pyro rocket at the next launch event?
Yes. That is the plan ... the HPR launch is scheduled to around mid September :)
@@AirCommandRockets Very exciting, can't wait! Good luck with the rest if your projects!
how long do you think the launcher will take to assemble on-site?
I am expecting to set up everything at the launch site and prep the rocket to take about 4 hours. We may set up the launcher the day before, and then launch the next morning when winds are calm.
You blokes are very switched on.
just land the boosters nozzles end down with some control fins and burners like SpaceX does, surely it can't be that hard...
Hello sir What should be the distance of the rope from the center in parachute
Are you asking how long the shock cord should be from the rocket to the parachute shroud lines?
@@AirCommandRockets yes
@@ahmeterenbahcac7436 There is no hard and fast rule on that. A longer shock cord is better at absorbing shock when the parachute opens suddenly. But a longer shock cord weighs more and takes up more room. I would say anywhere from one length of the rocket to 5 times the length of the rocket would be normal.
Could you please share the code?
Do you have a community group? or a discord server?
Nothing specific, though we do contribute to a number of forums/facebook groups/sub reddits/discord channels.
12:14 - Yes... why is that?
It's the airflow that spills out from the underneath and around the parachute. Normally it is pretty even all around with a single chute, but the place where these flows meet from the two chutes it creates a higher pressure, and so it pushes them apart until you reach an equilibrium.
@@AirCommandRockets - Ah, that makes sense, thanks!
