with a large throat on the nozzle.
Burnsim doesn't work well on long, thin motors - it does not take into consideration erosion burning down the core. The cores are 1/8th up to 3/8ths, with a large throat on the nozzle. I'll video & post burn here.
Easy Answer - What could possibly go wrong?
Real Answer - Worst case scenario is blowing out either the fore or aft seals, which will either plant it to the ground or make it a very bad rocket.
Besides, I'm a huge fan of lighting tripods
EDIT - Plus there is a whole 1.6 seconds of burntime.
impossible. 1600 x 1.6 = 2560Ns which would be a full K/baby L. and that is just simply not happening. how did you come up with those numbers?
True , but also mixing up fuel types and sharp stepped edges will shear AP just as easily. I would round over your edges on all your grains.
Agreed & already done
1.6 second burn J1600? What grain formula(s) from RCS are you using ? What holds the tripod in place ? Your neighbors may not like a J motor flying thru their yard if a leg pops and it turns into a land shark.
Silly question: how do you get an igniter into a 1/8" core that far up a motor?
I'm also looking forward to videos/data from the test.
Fail. Kablam. I'm done
Before you bail completely on making motors, can you do something less ambitious (say 1-2 grains of the same approximate size)? My understanding is that it takes the pros a long time to work up to a 30:1 motor like this one.
Payload, how long have you been making motors? The motor you attempted here is a very challenging one to get right, even for experienced research flyers.
