WebReturning to the fin flutter formula we can put it all together: Howard tests his model with a particular fin with root chord 9.75”, tip chord 3.75”, height 4.75”, and thickness 0.125”, and with a shear modulus of 380000 psi. I was able to duplicate his results quite closely especially when using a scale height H = 26500 ft. Webface finish on the fin, airfoil used, area of the fin, the length of the fin chord, and the speed at which the rocket travels. The last two factors are also used with other parameters to deter-mine the Reynolds Number for the rocket. The Reynolds Number is often used to determine the Coefficient-of-Lift of the fin at various angle-of-attacks (AOA).
