What is the combined lift function of the CV-22 in VTOL mode similar to?

The combined lift function of the CV-22 in VTOL (Vertical Take-Off and Landing) mode is similar to that of helicopters because both systems utilize rotating blades to generate lift directly in a vertical motion. In this mode, the CV-22 employs its rotor assemblies to lift off the ground, much like a helicopter does, allowing it to operate effectively in environments where traditional runways might not be available.

This similarity manifests in the ability to hover, take off, and land vertically, which is a characteristic primary to helicopter operations. While the other options might involve different methods of generating lift—jet engines provide thrust rather than lift in a vertical sense, tiltrotors incorporate rotor functionality that is adjustable for horizontal flight, and propeller aircraft typically rely on forward motion for lift—none replicate the precise vertical lift capability central to helicopter operations that the CV-22 also uses in VTOL mode.
