Shower thought of mine, theoretically, could spica in far future evolve into orbital laumch vehicle with addition of smaller stages on top instead of manned capsule?
I don’t see why not! In a way that’s what they did to the Atlas, started off as a suborbital icbm and turned into a rocket capable of planetary missions with the addition of Agena and Centaur!
How are you dealing with aerodynamic weirdness? I’m not expert but this is how i understand it: If your canards are much shorter than your stability fins in the back. When you deflect the fins it can tend to cause super weird aerodynamics effects. Also you get stuff like flow separation, control reversal. Fin control is insanely hard.
You have to be able to understand your rocket angle of attack and a few other variables. And The dynamics of how the fin control angle translates to angular acceleration to the rocket, in order to derive a control system that is able to work. Very very hard
i mean, you WANT the canards to be much smaller than the rear fins. if they were the same size, the CoP could get in front of the CoM and then it would flip and RUD in flight. keeping the canards small makes their impact on the CoP less and the servo gear going in the nose helps keep the CG and avionics wiring toward the nose. just my 2 cents
@@chrismofer How would aerodynamic instability cause a RUD? All I can think of is tumbling so violently it gets torn apart first, explodes second. Other possibility is necessitating use of the FTS.
Short-range AA missiles aside, usually you do not want canards for active control on a rocket-powered objects since it is not stabilizing, causes extra drag and generally doesn't help area-ruling. On short-range AA missiles canards are used to destabilize/keep the missile close to neutral stability in order to turn and hit a high-maneuvering target. What is the practical reason for putting them on a space-rocket?
@@CopenhagenSuborbitals Do you mean the US style "model rockets"? Because new years fireworks rockets sold in Denmark tend to be cardboard with solid propellant.

excellent music choice
Really love to see the support and efforts of rocket nerds like me to make this project..
Great news, looking forward to the first guidance test!
And really great to see the engine running again 😊
superb music choice. yall doing us (europe as a whole) more of a favor than you get credit for.
Been following you guys since I was 13 ( i'm 23 now), love everything you guys do and can't wait for the future of Copenhagen Suborbitals
Well done guys. Great progess.
That’s perfectly fit well for home defense SRBM
Dear Suborbitals, could you please make a video that discusses the launch rail and its design? Thanks!
nice EDA music
I think we might have to talk about open source military applications soon.

That would be amazing!! Though very hard
Je suis Jean Patrick je m'intéresse beaucoup à vos projets
Denmark --- once a powerful empiren --- and now suborbital

That's a topic for a video down the road. But this is why these quick and cheap model rockets came into the picture.

You guys are so much more professional and organized than Elon mush. If only you had more funds, I'm sure you'd use them more efficiently as well

How likely is it that there will be more missions past Spica 1?
cardboard rockets weren't legal in Denmark?
Correct.
@@CopenhagenSuborbitals why not?
Well, cardboard's out; and no cardboard derivatives.
@@CopenhagenSuborbitals Do you mean the US style "model rockets"? Because new years fireworks rockets sold in Denmark tend to be cardboard with solid propellant.
Yes but ar only legal to fier between cirsmas an 3 of January.
What safety standards are you applying for the active guidance of your sub-orbital rockets?
looks like you have a raspi pico, imu with different dc convertor?
don't tell me you wanna be the Linux of Rocket Companies ..... probably, I gotta smoke now and watch it in Danish
Can't believe you're using arduinos and pi picos
Is the software open source?
ngl u full rubbed my hands together before this shit
The rob dam of space programs 😬
Did I just saw klima motors?
So no public comments about the legislation foul up that's suddenly incoming.
The Chinese will steal this from you, and claim that you stole it from them. Good luck it's a great idea
Why does the narrator sound American?
The USA will win the civilian space race! 😱🤪🤣👍🇺🇸
Probably yes, "For all mankind". Remember?
@@petermaersk-moller3014 Oh yeah! That's right OK! 😁👍👍🇺🇸
