Osprey V22 VTOL Propulsion System Draft 1 (w thesis statement)

A V22-Osprey uses a tiltrotor propulsion engine system which combines the capabilities of helicopters and fixed-wing aircraft. The propulsion system functions follows the tilt wing concept as it uses two large tiltrotors mounted on the wings which consist of multiple engines to takeoff. 

The tiltrotor has rotational capabilities that allow the VTOL to perform vertical takeoff/land like a helicopter. Still, at the same time, it can also perform a conventional forward flight like an airplane. But a negative comparison to the harrier (a VTOL but with a different engine) turbofan engine is that the aircraft is affected by dead weight that comes from the Osprey Tilting apparatus.

The way the tiltrotor works during the takeoff/landing phase, the rotors will generate lift when doing a vertical takeoff while during a forward flight, they will act as propellers which helps generate high lift and keeps the fuselage horizontal. This hybrid functionality allows the Osprey to switch between hover and high-speed cruise. Thus making it versatile for military operations such as transport, search and rescue, and aerial refueling.

With these key features, the V-22 Osprey propulsion system is clearly more versatile then the harrier turbofan engine, which were vital for the success of combat, humanitarian relief and rescue operations that required the capabilities only the Osprey has.
