Questions about PhysX in UE4

When we are trying to simulate physical effects, we can design any Transform to move the Actor, or we can use physical materials and forces. If we use physical materials and forces, we give our Actor to the PhysX engine for simulation. I know these at the moment.
So, if I add a force which is related to the speed of Actor. For example,the lift on the wing is related to the speed in the X direction of the aircraft. Then I’m missing a parameter - the speed of the plane. I’d like to ask, do I have any way to Get the Actor speed from PhysX?Can PhysX output the Actor speed?
