This is my first new design this year (IIRC), and might even be my first in over six months! I've been 'recharging my batteries', and it's been a slow trickle charge fer sure...
First item: RockSim is throwing up a NAN on this design, for reasons I can't locate. It may be my installation of RS acting funny, so if someone could run a few sims with the file, I'd like to hear.
Second item: This is not true-scale, in that the lines of the Dragon QTV are totally wrong, and the lengths of the tubes are wrong. However, the length of the model is 1/70th the stated length of 178' for the prototype, and the diameter of 2.04" (ST-20) is only 0.01" smaller than the prototype diameter of 12'. If I can locate the correct shape of the QTV spacecraft and other dimensions, I'll correct this design. In any event, this should be an impressive bird in flight.
Specs:
Length: 30.51"
Diameter: 2.04" (ST-20)
Weight: 3.71 oz
Fin Span: 4.04"
Use a 3/16" launch rod. Since the simulations were NAN, I don't know about guide lengths or deployment velocities yet.
See what you can get it to do!
