A vertical takeoff and landing (VTOL) aircraft is a vehicle that can depart, hover and land vertically. This includes fixed-wing aircraft with the ability to take off and touch down vertically as well as helicopters or other aircraft with powered rotors.

VTOL aircrafts' ability to take off and land vertically as well as hover, fly slowly and land in small spaces distinguish it from the conventional aircraft. VTOL technology allows vehicles to land almost anywhere. This makes VTOL aircraft more flexible and, therefore, able to perform actions that are impossible for conventional planes. This flexibility creates a major advantage for aircraft in combat or rescue situations.

Unlike in conventional aircraft, the design used in ARION aircraft incorporates Rotating Detonation Engine (RDE) for powering the aircraft. It has an advantage over the conventional engines, due to increased thermal and fuel efficiencies, reduced weight and also higher specific impulse.

Since takeoff and landing are not controlled by the wing of a VTOL aircraft, then the vehicle can be built in such a way that the wings are optimized for speed and efficiency. This construction can also help reduce the drag experienced by the aircraft, making it even faster

While the future looks bright for VTOL, there are still huge amounts of technical challenges on both the aircraft and infrastructure side as well as regulatory hurdles for the design and operations of the aircraft.
