Hey, Chuck, whaddya think - the 60 ammo, batteries and chow on the right and the snivel gear on the left gonna work ok?  |
Jumpmaster must now calculate for spin drift.....egads!
F = 1/2 p V2 A Cl
F = lift force
ρ = density of the fluid
V = velocity of the ball
A = crossectional area of ball
Cl = lift coefficient
The lift coefficient is very dependent on the spin ratio ( (angular velocity*diameter)/(2* linear velocity) of the ball. Lift coefficient may be determined from graphs of experimental data using Reynolds number and spin ratio. Typical lift coefficients of a smooth ball range from 0.2 to 0.6 for spin ratios ranging from 0.5 to 4.5.
Then strap that on 12 guys and set them loose
