In addition, the implementation of each node for fastening the ends of the flexible rods to the blades in the form of a rod connected to the blade with the ability to rotate around an axis parallel to or coinciding with the line of the corresponding blade, ensures, with a minimum hydrodynamic resistance and mechanical loads on the blades, the optimal value of the blade elastic resistance. The placement of the flexible rod fastening units in the plane adjacent to the corresponding blade and located at a distance from the leading edge of the blade not exceeding 0.25 of its blade length is determined by the fact that the location of the above-mentioned planes at a cut exceeding 0.25 of the blade length of the corresponding blade may cause instability blades in the blade. From the other side, the position of the same plane of the second wet blade leads to a decrease The efficiency of the beneficial action of the blade is neutral due to the combined shear and angular oscillations The axis of fluctuations will be located behind the fastening nodes.

The second edge blade 2 is connected by means of flexible rods 6 and 6 with the hydrodynamic deepener 3. For controlling the orientation of the wave propulsor, the hydrodynamic deepener 3 is connected to the vessel 1, at least, by one additional flexible connection 17.

Each blade 2 is connected to each flexible rod 4 at points 19, 20 and 21, located on the same connection arc οτ arc. The extreme points 19 and 21 are connected respectively to the upper 13 and lower 14 surfaces of the corresponding blade 2 via flexible struts 18, and the front edge 16 of blade 2 is connected to each rod 4 at point 20.

The ship 1, rolling on the waves, has six degrees of freedom, namely: displacement in the direction of three mutually perpendicular axes, as well as rotation around the axes indicated above. The movement of the vessel 1 relative to any degree of freedom causes the displacement of the flexible rods 4 1 , 4 П , 5 1 , 5 П , 5 ЙП , 5 йν , 6 1 and 6 П , primarily in the longitudinal direction.
Пρи πеρемещении судна 1 (за счеτ κачκи) ввеρχ προисχοдиτ ποдъем гибκиχ τяг 4 , 4 , 5 , 5 , 5 , 5 , 61 и 6П, а следοваτельнο и связанныχ с ними лοπасτей 2 , 2 и 2 .

Пρи эτοм, на узлы 7 κρегагения κοнцοв гибκиχ τяг 41, 4П, 51, 5 π, 5ΙП, 5ιν, 61 и 6П будеτ дейсτвοваτь мοменτ сил, προπορциοнальный углу ποвοροτа лοπасτей 21, 2П и 2ПΙ и - 5 -When the vessel 1 moves upward (due to rolling), the flexible rods 4, 4, 5, 5, 5, 5, 61 and 6П rise, and consequently the blades 2, 2 and 2 connected to them. However, in this phase of the vessel’s movement 1, the rear edges of blades 2, 2 and 2, due to their inertia, also caused by the combined mass of water, move more slowly than the front parts of blades 2, 2 and 2, and therefore deflect downwards. Therefore, on nodes 7 κρagenium ends of flexible rods 4 1 , 4 П , 5 1 , 5 π , 5 ΙП , 5 ιν , 6 1 and 6 П the moment will act forces, depending on the angle of the blades 2 1 , 2 P and 2 PΙ and - 5 -

In this way, the tensioned flexible rods 4 , 4 , 5 , 5 , 5 , 5 , 6 and 6 essentially perform the function of an elastic element during the operation of the propeller.

Οднаκο в эτοм случае οни οτκлοняюτся не вниз, а ввеρχ.During the downward movement phase of the vessel 1 (during pitching), the flexible rods 4 1 , 4 П , 5 1 , 5 П , 5 ЙП , 5 ѹν 6 1 and 6 П are lowered downwards. In this case, similarly to the above, a lag of the rear clamps of the blades 2 , 2 and 2 ЙП occurs. However, in this case they do not deviate downwards, but upwards.

The horizontal component of the tension force of flexible rods 4 1 , 4 П , 5 1 , 5 П , 5 ПΙ , 5 ιν , 6 and 6 leads to the movement of the vessel 1 forward.

Such compliance is ensured by the presence of a hydrodynamic deepener 3, for which the characteristic is an increase in the deepening force with the speed of the vessel. As a result of the change in tension of flexible rods 4, 4, 51 , 5P , 5Sh , 5In , 6' and 6P , the mechanical moment on rods 9 increases, which causes blades 21 , 2P and 2IP to move to a position with a zero angle of attack.

This allows the system of blades 2, 2, 2 to be considered as a single hydromechanical system.

The only difference is that when the rear edges of the blades 2 are tilted up or down, the moment of force that tends to return the blades 2 to their original horizontal position arises due to the presence of flexible struts 18 between the upper 13 and lower 14, respectively. surfaces of blades 2 and points 19 and 21 on flexible rods 2.

In this case, one propulsor is recommended to be located on the bow of the vessel, and the other on the stern.
