Abstract:
An aircraft having a body on which is mounted an integrated lift, propulsion and steeing system inclusive of cycloidal propellers having horizontal axes of rotation capable of developing net thrust forces at any given angle in a vertical plane. Each propeller is externally driven and is formed with a circular array of blades at the periphery of a common rim and the blades can be turned to vary the angle of thrust by operation of a common control head.
Abstract:
This invention relates to naval construction and oceanology. It relates to a one-man submersible characterized, firstly, by external shapes designed to prevent any accidental fouling with any fixed obstacles; secondly, propulsion and steering units which give it excellent maneuverability and the possibilities of quick neutralization of any reaction experienced by the submersible; thirdly, by the fact that the operator has available a system comprising, at the extreme forward part of the submersible a swivelling and extensible tool-holder system with a coaxial and protected swivel seat; finally, a tall horizontal crane with one or two swivelling and extensible jibs, and four hydraulic columns with a special baseplate, these all being features which enable any work to be carried out with increased rapidity, accuracy and safety.The above submersible has numerous advantageous applications in various areas of ocean exploration and working.
Abstract:
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.
