New Plan -- Lirpa
So, I'm wanting to do something a bit more SciFi and Fantasy, and I'm holding in the back of my brain those interesting Sunward / Canaroc designs. I want something similar, but not exact, and which can be built from available Semroc components if possible. The Lirpa matches that set of requirements, needing only one set of custom centering rings.
The drawings from RockSim are, once again, showing the highly irritating limitations imposed by the program. The long bulkheads in the offset tube and in the pods are supposed to be nose cones.
The parachute goes in the large chin-mounted ST-10. A gas passage is required between the ST-10 and the ST-8. A baffle can be mounted in the ST-10, if desired.
The model will need a 48" x 3/16" launch rod. It reaches Fv in 37" on the C6-5.
Length: 27.75"
Diameter: 1.34"
Fin Span: 11.34" *
Weight: 3.5 oz
*This is the fin span reported by the simulation, however the outer 1.5" of each tip drops downward 90 degrees to become a pylon for the pod. RockSim is incapable of showing this at present.
C6-5......646'......Dv 14 FPS
I will try to work up some alignment templates and post these shortly to show you better what I had in mind.
Enjoy!
