Dear George, we thank you for sharing in detail a new mechanic. As always this is a wonderful innovation. I wonder how many people you and your father have already influenced in the world, I am an example of that. Congratulations.
Your channel is so great! Showing possibly unexpected challenges and how they are addressed, that 100G => everything weights a ton was something I would not have considered at a glance. Thanks for great videos over the years!
These videos are awesome!! Super enjoy them. Thank you for all the internal presentations as it shows your design genius!! Hope your record setting effort pays off!!
Very interesting! Love the bricks analogy! Makes you realise what the forces involved are! As always, excellent video! Can't wait for the next exiting episode!
greetings from Brazil to all. Hi, Australia. Awesome work. how many details !!! tests and new ideas. very good. Congratulations on sharing with the world. success.
Hi George! Very well designed nosecone and ejection mechanism. Have you considered using nylon instead of stainless steel screws? Do you think that they would snap under acceleration?
Thanks Daniel. I am sure nylon screws in this application would do just as well for the internals of the mechanism. You could certainly save a bit of weight that way. Though I am not sure how well they would do that connect the whole mechanism to the rest of the rocket.
Hello, I love your videos and I'm trying to replicate the parachute deployment system. Could you make the STL files available or tell me where I can find them?
Hi, unfortunately those STL files are not available yet. They will be released in a few months as part of a larger package. We have STL files available for the Nova rocket if that helps: www.thingiverse.com/thing:5502347
@@AirCommandRockets Hello, thank you for your response. Unfortunately, I specifically need those STL files, as the ones for the Nova rocket don’t fit my project. How soon will these files be available? I’m working under a tight deadline and can’t afford to wait too long. Thank you in advance.
I love how all of this was worked out, very clever. Well done and thank you for an in depth explainer video. Can i ask, what model number your keyfob camera is please?
Thanks. We use the #16 808 V3 from ebay. Here is a link to where we buy them from. www.ebay.com.au/itm/Mini-DVR-808-16-V3-Lens-D-Car-Key-Chain-Micro-Camera-HD-720P-Pocket-Camcorder/180937263580?epid=8018470764&hash=item2a20b389dc:g:aaoAAOxycmBS01Wl&frcectupt=true
Hi Basrockets. That's a good question. In our testing so far it hasn't had any effect on the reading. The recorded altitude plot did not show any spikes. The commercial units do a good job of filtering out any transients like that. Even with the previous designs there weren't any such transient evident in the recorded data and in those the altimeter was below the parachute so that when it ejected it would have created a low pressure pulse inside the tube. The altimeter one, two and three from Jolly logic are designed to attach to the shock cord under the nosecone and they also eject into the air stream, and also are able to filter that out.
Hi George & Crew Truly enjoy watching your videos. You guys come up with some neat rockets. What are you using for your electronics? Keep up the good work and fly safe. Cheers Willy
Thanks Willy. We build our own Servo Timers for controlling the deployment servo. We use commercial altimeters such as the zLog mod 6, AltimeterOne, AltimeterThree and Stralogger CF.
For the nosecone yes. The glass cloth is bias cut to make it easier to conform to the convex shape. For the body tube no. The fibers are 0 and 90 degrees to the tube axis.
Well SpaceX will need NASA to get to Mars. I think it will be a joint effort. As I see it, we are still at least 10-15 years away from a manned flight but probably more.

@@AirCommandRockets I find nylon screws are pretty much use-only-once because they do not handle friction or stress well. They are probably plenty strong enough, provided you never need to disassemble them, but they suffer wear [even against themselves] quite badly, and they also suffer fatigue if they are subjected to repeated uses at torque levels over 50% of their peak. This means that they can either strip out on you, or they can twist off on you if they are not handled with extreme care. Also I have no idea how much vibration your rocket delivers, nor how many times their tensile strength the mass of acceleration might deliver to them, so I think it would be good to test them before actually putting them into the final product. The aluminum, especially the military spec aluminum is hard enough to resist abrasion fairly well, and it is plenty strong enough and fatigue resistant enough to be R&Red hundreds of times at 50% of their peak torque without experiencing metal fatigue, on top of the fact that just like steel, they are typically being secured at torque loads well below 50% of their peak torque, which I fear is not going to be the case with nylon. I would certainly get the specs on the screws and even then do some failure analysis tests before trusting the mission to them. ~( 'w')/

14:43 That's how the Saturn V used that as an internal structure to support the Liquid Oxygen tank ontop of the RP-1 fuel tank.

Loving all these detailed design videos. Can’t wait to see the rocket smash some records! P.S. I really appreciate the shot with the rotating labels 😉
Thanks for that. :) John was actually inspired by your video to add those! He is learning Premiere Pro at the moment.
Air Command Rockets Haha good to hear my video is still having influence to this day. Tell him to keep up the good work!
Congratulations George, as always in constant evolution. Remarkable in the 15:55 minute, that is called practicality :) Greetings from Uruguay
Hi thorinti. Greetings from Sydney. :)
Awesome work guys!! very exciting the progress you have made
Another great video and amazing development work. My compliment George.

Just found your channel and watched you make the chambers ,it’s so technical ,are you planning a world record attempt ,keep up the good work 👍👌
Love your work George..
Pretty amazing stuff! Great mechanism :)

Very nice serie guys! Does the shock from the parachute deployment not effect the altimeter now it is outside the rocket?

With the plain GF do you lay it up at an angle (the actual fibers)?
For the nosecone yes. The glass cloth is bias cut to make it easier to conform to the convex shape. For the body tube no. The fibers are 0 and 90 degrees to the tube axis.
Excellent Project! What servo timer are you utilizing?
We use these: www.aircommandrockets.com/servo_timer_V2_0.htm
Thanks you for knowladge🙏🙏🙏🙏🙏
What is the outer diameter of the pipe???
60mm
Why not 3DP the entire cone?
Also, beautiful editing!
We actually tried that, but the strength to weigh ratio of the fiberglass is much better.
@@AirCommandRockets oh, you explained the weight thingy in the video. Great job George!
Magnificent!
Hi would you rather spacex or NASA?
Not sure I understand the question.
What’s going better in the space race to mars NASA or spacex

Very cool, why not normal rockets do you ever do normal rockets or just water
We do regular solid propellant as well. ruclips.net/video/K07TM7cuvMQ/видео.html
@@AirCommandRockets saw the video thats pretty cool. Im building a rocket with landing legs grid fins and its going about 1500 Feet

Can you get alloy aluminum screws for the assembly? ~( 'w')/
That would certainly be possible. Some have also suggested nylon screws which would also work.
