Definitions

  • the device, object of the invention entitled: "Device for Conditioned Inertia of the Fluid Fluid", is intended to accelerate a flow of fluid passing through it, to produce a thrust and a jet which is not very penalizing by friction, capable of producing the special effects described later.
  • Fully faired thrusters are severely penalized by the friction caused by fairings, a centrifuged and stirred fluid. If the mixing of water can make one think of the pressurization of a gas, of a favorable state to create a jet, it is in fact a waste of friction of molecules between them and on the fairings. To avoid at the rear of the propellers, this depression which occassione the resistance of the base, such a jet can not bypass the hubs, borrow a conduit which tightens, only at the cost of significant friction.
  • Document GB-A-1 011 203 relates to a jet propellant illustrated by this state of the art and in which it is proposed to restrict the jets to increase their speed, with a corollary an increase in internal pressure in line with the central section which is very penalizing.
  • the present invention aims to reverse this situation of the existing technique, which is not entirely satisfactory. This consists of putting centrifugal force on its side, to create the conditions for a more gradual acceleration of the fluid, dodging significant friction by accompanying the surfaces. Of the streamlined propellant type, the device largely gives up creating an immediate thrust effect.
  • This first phase which consists in transforming the work of one or more driving couples into kinetic energy of the fluid, is characterized by the fact that it increases this kinetic energy.
  • the second essential phase of the process being carried out by the meeting with the organ called "Wing", of this relay energy which is the accelerated fluid, thus producing the desired effect.
  • the airfoil is characterized by the fact that its surfaces, subjected on the part of the fluid under pressure, depression, react, deviating the trajectory to finally make it tend towards a preferred direction. Generally subjected to several jets from the previous organ, the airfoil produces several elementary jets tending to be decentrifuged, linear, homogeneous.
  • the fluid acceleration member essentially consists of one or more hollow bodies of revolution, containing the fluid drive members, these elements being set in rotational movement by the action of one or more driving couples.
  • this unit exerts a mainly centrifugal acceleration effect.
  • the centrifugal force is essential to this spiral path of the molecules, and used to advantage to order them against the walls which accompany them as much as possible in their movement.
  • the vacuum left in the center of the acceleration member by centrifugation, the increase in internal diameters, the longitudinal acceleration of the fluid tends to create a return of fluid from the rear in the acceleration members, generally not desirable.
  • This space is careened taking into account the parameters that determine it, or pressurized by giving itself the means.
  • a conduit is arranged through the center of the hubs or passing through the airfoil or the jet. Engine exhaust can be exhausted in this way.
  • the wing by its ability to make the trajectories tend towards the privileged direction which characterizes it, adapts its forms to the desired goal: reverse wing, lateral thrust, pumping wing.
  • the use of hollow bodies of revolution carrying wings is desirable for the elements intended to be driven in a rotational movement.
  • the wing can be partially fixed or entirely fixed. If it admits an axis of symmetry, the jet of annular section is of frustoconical shape open or closed, or cylindrical (Fig. 2). Becoming asymmetrical to facilitate installation on board, the airfoil allows the jet to be deflected or offset.
  • a jet of annular section highlights the ability of such a curtain to maintain the difference in pressures exerted on either side by fluids.
  • the molecules meeting this curtain are entrained and evacuated.
  • the center is put in depression if it is not caré or pressurized in the same way as for the previous organ.
  • the jet produced is an open frusto-conical film.
  • the device Directed against a wall, it delimits a space in depression, the fluid being sucked in the center and evacuated by the jet. Within a certain distance from the wall, the suction becomes preponderant over the thrust, the device forms a suction cup.
  • An underwater diver using a device according to the invention the suction of which is in the opposite direction to the thrust and which advantageously produces an open frusto-conical jet, made up of sufficiently numerous elementary jets, can direct it against a wall, attach to it with this hydrodynamic suction cup. Overflowing members preventing the device from coming into contact with the wall, causing the interruption of the phenomenon.
  • Jets forming waterproof curtains directed against solid or liquid surfaces, or other curtains, make it possible to participate in the partitioning of pressurized volumes, to bring the unalterable flexibility that may be necessary.
  • a succession of curtains makes it possible to add tolerable pressure differences for each of the waters.
  • the surface of the water, the deck, the two hulls, as well as a front and aft partitioning supplemented by such curtains constitutes a pressurizable volume, making it possible to lighten the ship of all or part of its weight, to better propel it.
  • the jets having played this role if they meet to be diverted, profiled surfaces integral with the ship, can still participate in the propulsion. These surfaces may belong to pads with a hydrodynamic effect.
  • the jets forming such curtains have not necessarily been accelerated in accordance with the invention, whether for a part of them, or in whole.
  • sirle device allows by its principle to dodge significant friction, there are unnecessary, inevitable, penalizing.
  • the care taken in drawing the profiles of hollow bodies, blades and their distribution the care taken in polishing the surfaces, in the use of lubricated or self-lubricating materials for the surfaces concerned has an impact on the yield.
  • the best way to make the device according to the invention consists of a marine jet propellant of the hydro-jet type, fixed inside the ship.
  • the accelerator consists of a hollow body of revolution with a flared profile, offering an increasing internal diameter (1), carrying eight profiled axial blades (2), and a propeller with two adjustable blades (3). .
  • the vacuum which would be created in the center is careened, a shutter plate (5) closing this fairing (4).
  • the closure plate has its periphery secured to the hollow body, and fitted with orifices through which the fluid passes.
  • the acceleration member forms an integral assembly, the transmission axis coming to be centered in a bearing (6) integral with the airfoil.
  • This member is surrounded by a fixed fairing (7), crossed by the shaft at (8), the seal being ensured by a cable gland.
  • This fairing open in the direction of the supply forms a fixed nozzle at (9), at the entrance to the acceleration member.
  • Semi-tight seals (10) and (10a) delimit a gap provided with vents (11), allowing the water to be evacuated by centrifugation.
  • An air inlet (12) allowing the replacement of the evacuated water by air reducing friction.
  • the airfoil consists of a hollow body of revolution (13) centered on the same axis, made integral with the previous fairing, and fixed to the ship.
  • the hollow body carries twelve decentrifuge fins (14) connected to the centering bearing.
  • a conduit (15) passing behind a fin makes it possible to act on the pressure in the center. Evacuation takes place aft of the ship, preferably in semi-immersion, allowing priming without requiring other arrangements.
  • the adjustable jet or directed on orientable surfaces provides the steering.
