Which component acts as thrust when the rotor disk is tilted?

Explanation:
When the rotor disk is tilted, the thrust vector tilts as well. Thrust is the force along the rotor axis, so tilting the disk creates a vertical component that helps lift and a horizontal component that pushes the aircraft forward. In level forward flight, the horizontal component is what provides thrust in the forward direction, while the vertical component continues to balance weight as lift. So the horizontal part of the tilted thrust vector is the thrust, and the vertical part is lift.
