How to blend two different animations on different bones in one skeletal mesh?

Hello !! I stucking on animation phase with my non humanoid skeletal mesh. Its not a vehicle, its just HoverEngine with many moving part inside (9 parts). I want to blend 2 animation on 2 different moving parts to play together but with different playrate. Engine have HoverBlades and Turboblades. If i animate this parts to different animations (rotating) for blades and turboblades, how i can blend them together to play in StateMachine (or blendspace)?
