| Abstract: |
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.

What I claim is:
1. A submersible aircraft having a three-dimensional freedom of movement in the air and in the water and comprising:
- a. a frame;
- b. a first rotating lifting rotor;
- c. a second rotating lifting rotor;
- d. said first rotor and said second rotor rotate in opposite directions;
- e. a prime mover operatively connecting with said frame;
- f. a first means operatively connecting together said prime mover and said first rotor for rotating said first rotor;
- g. a second means operatively connecting together said prime mover and said second rotor for rotating said second rotor;
- h. a control means for controlling the speed of rotation of said first rotor and said second rotor;
- i. said first rotating lifting rotor having an inner diameter;
- j. said second rotating lifting rotor having an outer diameter; and
- k. said outer diameter being smaller than said inner diameter so as to allow said second rotating lifting rotor to be positioned inside of said first rotating lifting rotor.
