I'm back with another build!
This time with 2 stages. I got the idea of making one after I saw a beautiful two stages launch at the 2019 ALRS, in Switzerland.
My plane is to build a versatile and high-performance sustainer. I will go for a 29mm airframe with a 24mm motor mount to keep the altitude "low". Here in Europe, most of the launch site is limited to 2km waivers, sometimes 3km. I will definitely fly the sustained alone on an F240.
For the booster, I want to keep it simple as this is going to be my first two stages. I still need to figure out the electronics for the sustainer ignition.
I will make a Delrin transition then epoxy a carbon coupler tube for the connection.
Don't mind the " separation shear pin"
The booster will have a 38mm MMT while being 54mm in diameter.
I'm also going to roll all my tubes bit, not the carbon fiber coupler that I will use as mandrels. I will not go in deep on the subject as there's already a lot of threads about this.
I already made the 24mm MMT. It's 16cm long for 11.1g and only around 0.6mm thick.
Fins will be 2mm thick carbon similar to my other rocket:
The nosecone will be the trickiest part to do. I'm going for a 7:1 VK profile.
Has anyone already 3d printed a mold?
I have access to a 3d too so that might be a solution.
What do you think? Do you have any recommendation on flight computer with OVSI?
I'm going to post a screen capture of the .ork file as soon as possible.
