I'm starting work on my L3 project, which I've decided will be a little bit more ambitious than is really necessary, in an effort to minimize costs and maximize the value of the flight (my school is also in the early stages of planning stuff for another project that will achieve similar performance, and I wanted to test some hardware for it ahead of time). The basic idea is a 4" diameter rocket with a 75mm motor mount, and I'm planning on using an M1780, which should give an apogee of around 14,000' and max velocity of 1440 ft/sec.
The openrocket and rocksim files for the rocket are attached (my L3CC recommended I use both, and for something of this magnitude, that seems rather prudent), though I'm really not inclined to put a huge amount of stock in their predictions until I've got a better handle of the Cd for the rocket after a flight test.
Beyond the standard 'do you see anything wrong?' I'm wondering if any of you can point me in the direction of someone who can do custom CNC'd and anodized aluminum bulkheads for the project (I'd like this rocket to last a while, and would like the additional corrosion resistance on the bulkheads).
Current plan for recovery is drogueless from 14k' with either a 60" SkyAngle Classic or a Cert 3 Medium as my main (depending on how heavy it ends up being - hoping I can get away with the 60"). Altimeters are an SLCF and an RRC3 as backup - tracking is a custom-built Arduino based GPS/accelerometer/barometer unit with a 2.4 Ghz radio, and a backup MissileWorks T3 (900 Mhz).
