[QUOTE="Hugnot, post: 2589302, member: 115658"] Thinking about the differences between airfoils having parabolic drag descriptions & bullets. Airfoils or wings on an airplane having a means of propulsion. Bullets, wingless, no lift component, subject to continual deceleration. Do parabolic shaped graphs describe drag on each? For wings would decreasing speed or shape of the airdfoil reduce drag or turbulent flow? For bullets, would constant deceleration reduce the drag caused by gyroscopic precession (angular momentum?) causing the bullet to fly more point forward. Would bullet skin friction be less as any skin friction reducing effect of anular grooves would be improved as bullet attitude changed? [/QUOTE]
