An aircraft of disc-shaped configuration provides the capability of vertical take-off and landing; straight horizontal flight; and three-dimensional maneuverability in the air by means of a plurality of counter-rotating lifting rotors assembled of fixed pitch or of self-adjusting pitch aerofoil blade elements; and, submersibility of the aircraft in water is achieved by means of a marine propulsion module using two counter-rotating hydrofoil rotors for up or down thrust, and a tunneled conventional marine propeller for horizontal travel. The marine propulsion module is detachable for emergency and for use with the main frame aircraft of a variety of other detachable modules for different tasks and missions. Exceptionally adaptable for any existing power plant, including nuclear, it is best suited for the environment-friendly types, like integrated steam motor on hydrogen and oxygen burning. The simplicity of the design and its mechanical efficiency are combined with several novel safety features, while displaying an attractive technological continuity for any conventional aircraft manufacturer. The downstream of air from the lifting rotors utilized for maneuvering by a system of vanes positioned below the rotors. |

DETAILED DESCRIPTION There is disclosed an aircraft capable of movement in three directions, in Cartesian coordinate terms the x-y-z directions, in the air.
The movement can be a combination of vertical and horizontal.
The aircraft comprises a frame, an engine or power plant and two counter-rotating rotors.
The engine or power plant through suitable gearing rotate simultaneously the two counter-rotating rotors.
There are vanes for vertically positioning and horizontally positioning the aircraft.
Further, this aircraft is submersible in water.
This aircraft can move on water or below the surface of the water.
The aircraft has three-dimensional movement in the water such has in the x-y-z directions.
The aircraft can have various horizontal positions and also various depth positions in the water.
The aircraft can move in the water, on the water and in the air.
OBJECTS AND ADVANTAGES A primary object of this invention is to provide an aircraft of the above-mentioned characteristics and capable of performing movements with three-dimensional freedom and designed speed while retaining horizontal stability at all times, either in hovering over one spot, or flying unidirectionally at a maximum speed.
Another object of the invention is to provide an aircraft adaptable to many existing engines or power plant types, including nuclear power, while best suited for environment-friendly Hydrogen fired Integrated Steam Motor (pending U.
