A submarine device having a hull which is substantially symmetrical about a horizontal plane of symmetry and vertical longitudinal and transverse planes of symmetry. An integrated lift, propulsion and steering system is provided for the submarine device and comprises four conventional cycloidal propeller mechanisms in an arrangement in which two are mounted at the front of the hull and two at the rear, the two at the front being rotatable about a common transverse horizontal axis disposed below the horizontal plane of symmetry whereas the two at the rear are rotatable about a common transverse axis disposed above the horizontal plane of symmetry of the hull. Four auxiliary screws, rotatable about horizontal axes, can be arranged in pairs on the horizontal and vertical planes of symmetry respectively, the auxiliary screws having reversible blades and being capable of turning to produce vertical thrust.
A submarine device capable of perpendicular translation relative to its longitudinal axis inclusive of purely upward and downward movements using an integrated system of lift, propulsion and steering, said submarine device comprising a hull with a center of symmetry and vertical and horizontal planes of symmetry passing through said center, said integrated system comprising four cycloidal propellers grouped in pairs, one pair being forward on said hull and one pair aft on said hull, each cycloidal propeller having a horizontal axis of rotation and including a flat circular rim carrying at its periphery a circular array of identical horizontal blades each rotatable about a horizontal axis perpendicular to the said rim, means for rotating the blades about their axes including a jointed connecting rod for each blade extending parallel to the plane of said rim, a master control head coupled to said rods and capable of being staggered relative to the axis of rotation of said propeller, said two pairs of cycloidal propellers being symmetrically arranged relative to said center symmetry of the hull, the forward pair being lower and the aft pair higher, the two propellers of each pair being coaxial and symmetrical relative to the longitudinal vertical plane of symmetry of the hull, the directions of rotation of the propellers on each side of the hull being the same, four auxiliary screws suspended from said hull and having rotatable and reversible blades with axes of rotation perpendicular to the longitudinal vertical plane of symmetry, two of said auxiliary screws being on the longitudinal horizontal axis of symmetry one forward and one aft and two on the transverse vertical axis of symmetry one above and the other below the horizontal plane of symmetry, the two screws on the longitudinal axes each being able to turn through 90.degree. around the longitudinal horizontal axis to produce vertical thrust to assist in purely vertical displacement of the submarine device.
A submarine device capable of perpendicular translation relative to its longitudinal axis inclusive of purely upward and downward movements using an integrated system of lift, propulsion and steering, said submarine device comprising a hull with a center of symmetry and vertical and horizontal planes of symmetry passing through said center, said integrated system comprising four cycloidal propellers grouped in pairs, one pair being forward on said hull and one pair aft on said hull, each cycloidal propeller having a horizontal axis of rotation and including means for adjusting the direction of net thrust produced by each cycloidal propeller in a vertical plane perpendicular to said horizontal axis of rotation, said two pairs of cyloidal propellers being symmetrically arranged relative to said center of symmetry of the hull, the forward pair being lower and the aft pair higher, the two propellers of each pair being coaxial and symmetrical relative to the longitudinal vertical plane of symmetry of the hull, the directions of rotation on each side of the hull being the same, two pairs of auxiliary screws suspended from said hull and having rotatable and reversible blades with axes of rotation perpendicular to the longitudinal vertical plane of symmetry, one pair of said auxiliary screws being on the longitudinal horizontal axis of symmetry and the second of said pairs being on the transverse vertical axis of symmetry offset from the horizontal plane of symmetry, the screws on the longitudinal axis being able to turn though 90.degree. around the longitudinal axis to produce vertical thrust to assist in vertical displacement of the submarine device.
