I am working on my Lev 3 design & have hit another snag. Simulations show ground hit speed of
over 100 FPS which is way high. With a 96" chute CD of 2.2 on a 40 LB rocket it should be more like
22 FPS or so. Changing chute diameter to 168" in Open rocket has little effect on descent speed.
Anyone got a clue? Open Roc file attached.
