G and its affect on drag

[keith williams]

I'm not sure why you were concentrating on drag to explain why Vs is zero in zero g flight.

But if the problem was how to explain the relationship between stalling speed and load factor the following may help.


L = CL ½ Rho Vsquared S


At the stall in 1g flight L = 1 x W = CLMAX½ Rho V1gstall squared S……equation 1

At the stall in 2g flight L = 2 x W = CLMAX ½ Rho V2gstall squared S……equation 2

At the stall in 0g flight L = 0 x W = CLMAX ½ Rho V0gstall squared S……equation 3


The general equation for stalling speed at any load factor is

Vs at any load factor = Vs at 1g x the square root of the load factor.
