Glider simulation

Pedro

Hi,

For a CFD project I have to simulate the trajectory of a glider launched from a plane, with no action from this latest. In other words it is like dropping a stone with two wings.. Even if it's not directly CFD related, it involves aerodynamics skills. The thing is that after a simulation of the different forces involved, I find that the vertical velocity of the glider stabilizes (wish is right) while the horizontal one keeps increasing till the impact on the ground. The glide angle keeeps incresing and then decreasing slowly, but never stabilizes.. How do you find these results? Does it make sense to you? Thanks for your advices!
