This is the first build effort I'm documenting here. Hopefully you will keep me on the straight an narrow.
Goal: A rocket capable of 10k' on a 54mm motor. I can tell you this goal won't be met. Early sims in RockSim limit indicate 9k'+.
Build techniques: All/mostly FG (G10/G12). Mechanical, not adhesive joining, as much as possible.
Materials: Easily purchased from vendors such as Mad Cow.
Electronics: 2 cameras (Run Cam Thumb is the initial thought), RRC3 primary, RRC2 secondary, RPi Zero W with pressure, temperature sensor and IMU.
The initial components are shown in the attached photo (from left front to right):
Existing electronics sled I designed for 3" - 4" bays. It consists of an RRC3, RRC2 (on the visible side) and a RPi Zero W with sensors on the opposite side.
54mm motor mount (G12, Mad Cow) to be cut down to, probably 20".
3 fins, isoceles trapazoid, cut from G10 (I could really use some help determining speed at which flutter will start).
3" coupler/electronics bay (G12, Mad Cow).
3" coupler, nose to ariframe (G12, Mad Cow).
AeroTech 54mm motor retainer.
12" nose cone (3" filament wound, Mad Cow).
3/8" tubular kevlar for chute harnesses.
3" x 60" airframe to be divided for dual deploy (probably about 24" and 36") (G12, Mad Cow).
The next step(s) are to design the bulkheads, centering rings, and thrust plate.
