- a propulsion unit 1 according to the invention comprises a rigid structure of 2.2 étanche closed and sealed integral with a tubular turbine 4.
- Said rigid structure 2,2 ⁇ contains a motor (not shown and a rotary shaft (not shown) driving in rotation at least one propeller 3, said propeller 3 being contained inside said tubular turbine 4.
- Said rigid structure 2,2 ⁇ consists of a parallelepipedic structure 2 consisting of a housing with 4 solid faces defining a parallelepiped and one open face of which is tightly secured to the tubular casing of the turbine 4 and the other open face ensures the tight connection with a 2 ⁇ parallelepiped cover covering the engine of the propulsion unit and the turbine 4.
- the parallelepipedic structure 2 defines a column having an axis of longitudinal symmetry LL 'corresponding substantially to the axis of the main rotating shaft directly driven by the motor inside the structure 2,2 ⁇ and connected at its other end to a angle return device inside the turbine 4 as described below.
- the tubular structure constituting the turbine 4 has a transverse axis ZZ 'perpendicular to the longitudinal axis LL' of the parallelepiped structure 2.
- the turbine 4 comprises at its center a base or casing 3 ⁇ containing an angle return device ensuring the junction between the main rotating shaft of the housing 2 in the direction ZZ 'connected to the engine in the hood 2 ⁇ and one or two rotating shafts in the transverse direction ZZ ′ connected to one or two propellers 3 contained in the turbine 4.
- a first propeller can be a supercharging tractor, a second propeller which is propulsive or the reverse when the direction of rotation is reversed.
- This two-propeller system makes propulsion very efficient with a symmetrical thrust in the two opposite directions corresponding to the direction ZZ 'transverse to the longitudinal direction LL' of the propulsion unit and the longitudinal direction XX 'of the boat.
- the propulsion assembly 1 is mounted inside a substantially parallelepipedic box 12 ⁇ , which cooperates by sealed junction along a junction plane 12 3 with a substantially parallelepipedic well 12 2 produced inside the hull and inside which a cutout 8 is provided in said shell 7.
- the propulsion assembly 1 is supported by the upper box 12 ⁇ whose lower edge 12 4 of the side walls is tightly fixed on the upper edge 12s of the walls sides of well 12 2 .
- the propulsion assembly 1 is integral with the box 12 ⁇ but movable relative to the latter, according to a uniform circular movement as will be explained below.
- a closure plate 6 reproducing the shape of the shell cooperates with a rebate 8 1 (4B) at the periphery of the opening 8 in the shell 7 so that in the retracted position (FIGS. 2A and 4A) the plate 6 is in perfect continuity with the rest of the shell 7.
- the closure plate 6 is connected to the turbine 4 by support elements 61.
- the propulsion assembly 1 is retractable or retractable using a rotation device which will be explained below and which generates a circular movement of exit from the well and the hull or re-entry into the well around an immaterial axis of rotation 11 (FIGS. 4A to
- the rotation device between a retracted position A inside the hull and a deployed propulsion position B in which the propeller exits outside the well and protrudes from the hull 7 below it comprises:
- sliders 9 ⁇ , 9 2 , 9 3 mounted on opposite faces in the transverse direction ZZ 'of the rigid parallelepiped structure 2 ensuring the junction between the turbine 4 and the cover 2-_. More specifically, sliders 9 ⁇ , 9 2 , 9 3 are supported by a triangular plate 16 mounted on either side of the parallelepipedic housing 2. These sliders 9- ⁇ , Qz, 9 3 are arranged on the plates 16 in a triangle and cooperate with slideways formed by circular recesses 10 ⁇ , IO2 provided in support plates 15 disposed opposite the plates 16.
- the two pairs of slides 1O ⁇ and 10 2 are arranged symmetrically on each side of said propulsion assembly cooperating with the slides 9-I-93 supported by the two plates 16 each also arranged on each side of said rigid structure 2 parallelepiped.
- the two slides 10 ⁇ , 10 therefore constitute female parts cooperating with the male parts 9 ⁇ , 9 2 , 9 3 .
- the slides 10 ⁇ , 10 2 define arcs of concentric and homothetic circles of the same angular sector, that is to say inscribed in the same circular section. More precisely still, a first slide 9 ⁇ is able to circulate inside a first slide 10 ⁇ and the other two slides 9 2 , 9 3 slide inside a second slide IO2 defining an arc located above of the first slide 10 ⁇ and defining a circular arc concentric with the first slide but of larger radius and according to the same angular sector (homothetic).
- the plates 15 in which the circular guides 10 ⁇ and 10 2 are defined are fixed to opposite lateral edges of the box 12 2 by means of second plates 15 ⁇ .
- the positioning of the plates 15 and 15 ⁇ in the box 12 ⁇ is carried out so that the circular slides 10 ⁇ and IO 2 have a circular center of symmetry (which corresponds to the center of rotation of the slides 9 ⁇ , 9 2 , 9 3 inside slides 10 ⁇ and 10 2 ), located at the level of the shell 11 (see FIGS. 4A and 4B).
- the slides 9 ⁇ , 9 2 , 9 3 consist of cylindrical fingers surrounded by rings 9 4 (see Figure 3) facilitating the sliding inside the circular recesses constituting the slides 10 ⁇ and IO 2 .
- the guide elements comprise a single slide 9 whose circular shape corresponds to the shape of the slide formed by a circular recess 10. It is understood that in this embodiment of the Figure 8, we can consider that the plates 15 ⁇ comprising the recesses 10 are integral with the rigid parallelepipedal structure 2 connecting the cover 2_ to the turbine 4 and that the triangular plates 16 supporting the slider 9 is fixedly mounted on the side walls inside the box 12 ⁇ .
- uniform circular movement is understood here to mean that the propulsion assembly does not have a relative movement of rotation with respect to the main circular movement of rotation around the immaterial center of rotation 11, imposed by the shape of the guide elements 9, 9 9 3 and 10,10- 1 -10 2 , which have as a center of circular symmetry said immaterial center of rotation 11 of the propulsion unit 1.
- the propulsion unit 1 moves uniformly in its circular motion. This uniform circular movement allows when the propulsion assembly passes from the retracted position inside the hull (A, FIG. 4A) to the deployed position outside the hull (B, FIG. 4C) that the plate d the shutter 6 immediately emerges from the opening 8, allowing only the turbine 4 and the propeller 3 to pass, which explains why the opening 3 can be of relatively small size.
- the circular movement of the propulsion assembly 1 inside the slides IO 1 O 2 or 10 is achieved by a displacement device comprising: - a motor 13 of the geared motor type cooperating with pulleys 13 ⁇ ,
- Said pulleys 13 ⁇ , 13 2 receive straps 14- ⁇ , 14 2 .
- a first strap 14 ⁇ called the descent strap is fixed at one end to a said pulley 13 ⁇ and at the other end to the upper cover 2-.
- Two second straps 14 2 called lifting straps provide the connection between pulleys 13 2 to which are fixed at one end and the turbine 4 to which they are fixed at their second end.
- the output or re-entry operation of the propulsion unit is controlled outside the box by a hydraulic, electric or compressed air system (not shown) which acts on the motor 13.
- the actuation of the motor 13 rotates the pulleys 13 ⁇ , 132 so as to ensure simultaneously the unwinding or winding of the descent straps 14- ⁇ and vice versa the winding or respectively the unwinding of the lifting straps 14 2 thus causing the descent of the turbine 4 and therefore the output of the propulsion assembly in the deployed position B or respectively the lifting of the turbine 4 and therefore the deployment in the position B or respectively the retraction in position A of the propulsion assembly inside the hull 7.
- the non-reversible nature of the motor 13 ensures that the propellant is blocked either in the retracted position A, or in the deployed position B at the end of the unwinding or winding of the straps 14 ⁇ , 14 2 .
- the rigidity imparted to the propulsion assembly according to the invention on the one hand by said rigid structure 2 and on the other hand by the guidance of said propulsion assembly 1 secured to the male elements 9 9 3 in pivoting to the inside the female elements 10- ⁇ , fixed IO 2 ensures the absence of deformation usually due to the torque effect generated during the active propulsion phase and thus makes it possible to overcome the fatigue stresses usually encountered on retractable thrusters. It also makes it possible to keep the exact coincidence between the closing hatch 6 and its housing 8-8 1 in the hull 7 thus preserving the hull 7 of the boat all its hydrodynamic performance.
- the motor, not shown, of the propulsion assembly, contained in the cover 2- ⁇ can be an electric motor, with compressed air or a hydraulic motor.
- this propulsion unit 1 is not subject to seizure during its outgoing or reentry movements in the well.
- the movement of circular displacement of the propulsion assembly makes it possible to reduce the bulk thereof within the hull insofar as it makes it possible to arrange it inside the hull in an inclination in retracted position A by an angle ⁇ with respect to the junction plane 12 3 (XOZ) between the box 12 .
- the design of the mounting of the propulsion assembly inside the hull mounted integrally on the box 12- ⁇ facilitates its installation inside the hull.
- FIGS. 4A, 4C there is shown an axis of rotation 11 situated at the level of the shell, but this can also be located below the shell insofar as the positioning allows instantaneous release of the closure plate 6 relative to the rim 8 1 of the opening 8 of the shell 7.
- FIG. 1 to 8 there is shown the propulsion assembly arranged inside the hull so that the propeller is of transverse axis of rotation ZZ 'perpendicular to the longitudinal direction XX' of the boat; however, obviously the propulsion assembly can be arranged differently inside the hull, in particular with a turbine with an axis parallel to the longitudinal direction of the boat to create a longitudinal propulsion rather than a transverse propulsion.
