I give you the SB-V1!
The "SB" stands for Summer Build and also for Side Booster. I guess it's a code name for now until I think of something better.
Update: the rocket's name will be "Maximilian"
The only way I could draw up what I had in mind is through RockSim since it supports functioning side boosters that separate.
Here is the first draft:
Here is the back view:
And the .rkt file
View attachment summer_build_v1.rkt
I only have the trial version of RockSim so it only sims to apogee. Seems pretty good. Apogee is nearly 2000 ft.
All three engines will be ignited at lifoff, the F15 burns for 3.45s and during this time, the D12s in the side will burn and eject the pods - I hope. What I'm not sure of is how well a D12-0 will do at ejecting the nose cone and streamer while under boost from the F15 - since it doesn't have an ejection charge per se. A D12-3 would work better but it's an extra 3 seconds of drag.
As far as the booster attachment / detachment mechanism, I was thinking of using slots/tabs which hold vertically but will slide out as if "peeled back" in the same manner that real side boosters do on real rockets. They will be held horizontally by a cord which will be burnt/cut by the motors at burnout.
