A quick "back of the fag packet calculation" gives me the following:

Lynx rotor disc diameter (as an example): 12.8M
Lynx blade tip speed: 700 feet/sec = ~ 214M/S

Centripetal Acceleration = (v*v)/r = (214 * 214)/6.4 = 7155 M/S^2
i.e 70g constant acceleration.

Err , maybe need to get your cigarette packet checked

Is 7155m/s^2 ~= 70g ? (More like: 700g)


i can understand that valves might have an issue at 700g, but why would a chip care about being at 700g ?
