Im working an upscale of the Estes 1376 NASA Pegasus bashed out of a Mega Der Red Max and a Leviathan. Im using MDRM construction techniques on custom lasercut fin cores.
Id like to get a ballpark idea of flutter velocity. Ive tracked down The Laminator mentioned in other threads, so I can work on simming my laminate.
But what to enter into finsim? The wing fins are TTW to the 4 main tube. With a notched tab at the forward tip to slip a half inch of coupler into to make another anchor point. But I plan on also filleting the wing fins to the 3 side tubes/pods.
So whats a reasonable approximation to set up in finsim? The portion of the 17 span that extends past the pod, and the 3 tube as root glued - Not TTW? Something else?
Ideas welcome.
