Fin Clamps For LV2c
Fin clamps allow us to use simple flat fins and attach them securely to any round shape. Individual fins are easily replaced.
The drawing here shows the old fin shape from LV2b. The next generation fin shape will no doubt be slightly different. The drawing also shows internal fin clamps. We considered these because they are aerodynamically cleaner and pick up some flutter resistance by passing through the outer fairing. Currently exterior fin clamps seem like a better idea because they are much easier to take on and off, align, etc. The aerodynamic drawbacks of external clamps are not too severe.
The drawing shown is available in PDF format as well in source (DXF) format.
