[@mr.h.7586]

I’m a pilot. 3 miles from launch at that altitude is simply Spectacular!!!

[@Jiminaus50]

Thanks. It's a bit more complicated. The stabilization system between the first and second stages oriented the rocket vertical by the time the second stage lit. Later, the rocket weathercocked into the jet stream, getting as far as 5 miles out, but then drifted back when it came back through the jet stream, ending up 3 miles out. But, if you're not vertical when the second stage lights, you can be 30 miles out in a flash.

[@connorreilly238]

@@Jiminaus50 Is there a system in place to prevent the firing of the second stage if the rocket isn't able to properly stabilize? Additionally, if a rocket going to that altitude were to get off track in a big way, are you able to track it still, or would it just be lost to the desert at some point? I'm interested in the controls that you had to implement when preparing for this. Also, very impressive. Bravo, and thanks for sharing.

[@Jiminaus50]

@@connorreilly238 The second stage has an altimeter that measures the tilt of the rocket. If it's over a set value (9 degrees as I recall in this flight), the second stage will not fire. The rocket has fps telemetry so as long as you can get a hit, you will know where it is. Range isn't infinate, and depends on the brand, but I have had hits from 30 miles horizontal. If the tracker is just a radio direction finder, it gets increasingly difficult to locate as it gets further away. Every now and then, you lose one.

[@generalripper1964]

Could you please explain the "spin can" and the "stabilization module" and how that worked or where to find the information. Beautiful flight. I am sharing. :-)

[@nytrunner9009]

Here's a link to the project overview for his guidance section (which prompted his development of the spinning tail unit): www.rocketryforum.com/threads/i-could-use-just-a-little-guidance.122042/

[@Jiminaus50]

The stabilization module is an IMU, not unlike an RC airplane autopilot, except modified in many ways for rockets. The development of this can be found on "The Rocketry Forum" under the thead "I could use just a little guidance". The module is intended to straighten the flight during the coast after the first stage burn. The spin can is required to prevent "control reversal", where vortices from the canards interact with (in this case) the fins on the first stage. Control reversal can cause the rocket to spin in the opposite direction of the intended path. A spin can is one way to solve this problem.

[@nshire]

Do the fins spin on their own or are they driven?

[@crxstalline_]

Absolutely mental. Especially that ground view, really outstanding.

[@mikef3720]

YEAH DID you see that obvious earth curvature they show you at the 4:02 mark of the video when it was only maybe 3000 feet off the ground...........???? PRICELESS, LAUGHABLE, FUN. he he he.

[@topsecret1837]

So I guess after 100,000 feet the rocket was going into a ballistic trajectory after clearing the troposphere and stratosphere for the most part

[@Jiminaus50]

That is pretty much the case. There is still air resistance though. During the tumbling part, starting at 140,000, there was still air resistance and the tumbling cost some altitude.

[@AeroBen]

Incredible. Excellent job Jim (and help)!

[@bud1412]

[@g2rockets]

Great flight Jim. So, when the pitch and roll resonance occurred, the rocket was in essence tumbling in an upward direction? Is this correct? And, could it have been a resonance between the Yaw and Roll axis's? Thanks and again great flight.

[@Jiminaus50]

It is certainly resonance. and it is certainly tumbling upward. I haven't been able to visualize the actual motion. The path of the motion does not repeat (as coning would do) and sometimes it is pointed downward. My best guess is sort of a waivy flat spin with a constant roll rate, if that makes sense. Very interesting whatever it is.

[@Rktman77]

[@davidhack6789]

At what altitude was MAX Q and at what speed? That's totally AWESOME that y'all got it to reach that high! Good flying and clear skies!

[@Jiminaus50]

I don't really know where MaxQ would be. I suspect it would be close to the end of the 3rd stage burn where the speed is the highest. That's certainly the point in the flight where I was wincing and expecting the worst! That was at around Mach 3.3 I believe. The rocket went pretty high, but I consider it to be more of a technical flight than a high altitude flight. The rocket isn't something stripped down to the minimum to get maximum altitude possible.

How does a rocket that's gone into the stratosphere land 3 miles from it's launch pad if the earth is rotating at approximately 1000mph?

[@sebastiannolte1201]

Why should the earth rotate underneath it? And I wonder: If you think that the earth rotates underneath something just because it has left the ground, then you don't need a rocket for that. You would not even land on the same spot when you just jump in the air.

[@wernerschulte6245]

[@julianchee2894]

How does the 3rd stage maintain stability at such altitudes where the air density is so low ?

[@Jiminaus50]

It maintains stability until somewhere around 120-140K. If it is going perfectly straight with no roll, it might go much higher. But, at some point, if there is any roll or coning, it will devolve into end-over-end tumbling. The idea for rockets that are not intentionally spun is to keep them from tumbling long enough so that the onset of tubling doesn't cause the air frame to fail. The longer you can hold off tumblng, the higher you will go. This flight lost about 10K due to tumbling. I have another that started earlier that probably lost 70K or so.

[@julianchee2894]

Do you have any plans to experiment with non-aero stabilization systems like yoyo despin (might not sit well with safety) or a reaction wheel for the 3rd stage ?

I also read of people in the comments of videos made from orbit who say "Why do they only show the earth all the time, why not the look to space?" Weird question. The view to earth is the only interesting thing. So imagine you are in a rural area at night, total clear weather. You lay down on your back and see all the beautiful stars. But now your bed that you are resting on is lifted up to 100 meters. Would the view be different? No, it would be exactly the same like from the ground. Then up to 1000 m. 10 km. 20 km. 50 km. 100 km. 500 km. 1000 km.... Do you think the view would change? No, it would not. Why should the view change?

[@Jiminaus50]

Don't mind at all, but it's not a simple answer. If one were to build the rocket and pad from scratch, all of the equipment might end up costing $20K, plus or minus. And, there is a lot of time invested (for example, all of the carbon air frame tubes are hand made), In reality, though, most of the parts are recycled from prior flights such that the costs during the year of the flight aren't that much. Travel is by far the biggest cost. No permit or club costs to speak of.
