Abstract

A propulsion system comprises a pushing blade 1, a steering unit, a transmission arrangement (Fig 7) and an engine (36, Fig 7). The transmission arrangement converts rotational movement from the engine into a figure eight motion in which the pushing blade is driven to propel a vessel 24 forward. The transmission arrangement may contain a longitudinal swinging mechanism (Fig.11), a transversal swinging mechanism (Fig.12) and a turning mechanism (Fig 10) which between them drive the pushing blade in the figure eight motion. The propulsion system may be used to drive both watercraft and aircraft.

Description

TURBULENT PROPULSOR

This invention relates to the propulsion system.

Most of the modern vessels are propelled by an engine and propeller. The rotating propeller throws the flow of water backward, pushing the vessel forward. Half of the engine's energy is converted into a backwards flow of water and only the second half of the engine's energy is converted into movement of the vessel.

It is well known, that when using this method of propulsion, it is impossible to significantly reduce power of the engine without losing the optimum performance of the vessel.

According to the present invention a mechanical transmission is provided which converts the rotational motion of the engine into the oscillatory -swivel motion of the blade. This motion creates turbulent vortices which resist the backwards movement of the blade, pushing the vessel forward.

A less powerful engine is required for the movement of the vessel with this type of propulsion system, as no energy is wasted On creating a sternward accelerated column of water.

On this type of vessel the circular variations of the directions of thrust provides effective steering control.

This type of propulsion can be used both for the watercraft and aircraft.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Fig.1 illustrates how turbulent vortices emerge when the blade is moving.

Fig. 14 illustrates a possible upgrade option such as integration of the engine into the oscillation transmission, or replacement of the balljoint in order to increase the angle of oscillation of the blade.

Fig. 15 shows how the oscillation transmission converts rotational motion into an oscillation trajectory of the blade.

As shown in Fig.1, when the blade 1 is moving, with the wide side perpendicular to the direction of movement 2, the turbulent vortices 3 emerges on the opposite side of the blade. These vortices 3 provide resistance to the movement 2 of the blade.

During the movement 2 of the blade 1, on the edge of its trajectory, the blade is rotated parallel to the direction of thrust 4 and does not resist the movement of the vessel, as shown in Fig.2.

Going through the middle part of its trajectory, the blade is rotated perpendicular to the direction of its movement 2. The emerging turbulent vortices 3 provide resistance to the movement of the blade, pushing the vessel forward 4.

For every turn 9 of the blade around it vertical axis, there is one swing 10 from side to side and two swing 11 back and forth, as shown in Fig5.

For the basic principal of the oscillation transmission is the transformation of rotation motion 8 by the crank mechanism 7 with the connecting rod 6 into swinging motion 5. The crank mechanism is connected to the toothed rocking lever 14 which turns the toothed gear 12 in order to increase the angle of turning 9 of the blade as shown in Fig.6.

A general view of the vessel 24 with the propulsive blade I and the protective dome shell 35 is shown in Fig.3.

The rotation motion 8 of the engine 36 is transmitted to the oscillation transmission via spur gears 16. The cylindrical shape of the oscillation transmission housing body 17 is rotated by the steering mechanism 15 with worm gear 19 in order to control the direction of the movement of the vessel, as shown in Fig.7. The vessel hull 24 and protective dome shell 35 of the bellows 18 are represented in the cutaway view.

The key principal of the oscillation transmission is the perpendicular arrangement of supporting brackets of the longitudinal 20 and transverse 21 rocking mechanism which has freedom of swinging, as shown in Fig.9.

Both mechanisms of the oscillatory movements are connected by the shaft with spline and the double universal joint 22 which has only one point of the bend. The first universal joint 31 is connected to the second universal joint 32 with a spring-loaded 34 floating centering element 33, as shown in Fig.13.

The overall look and layout of mechanical components in the oscillation transmission is shown in Fig. 8. The cylindrical housing body 17 and hermetically sealed bellows 18 are represented in the cutaway view.

The rotation motion of the engine 8 is transmitted through the double universal joint 27 to the bevel gears 29. The crank mechanism 7 with connecting rod 6 converts the rotation motion into a swinging motion of the rocking housing body 28, and is responsible for the longitudinal movement 11 of the blade, asshown in Fig.11.

Then the same rotation motion 8 is transmitted through a double universal joint 22 to the bevel gears 25. The crank mechanism 7 with connecting rod 6 cornierts the rotation motion into swinging motion of the rocking housing body 30, and is responsible for the transversal movement 10 of the blade, as shown in Fig.12.

The same rotation motion 8 is transmitted through a double universal joint 22 to the spur gears 26. The crank mechanism 7 with connecting rod 6 is converting the rotation motion 8 into swinging motion of the toothed rocking lever 14, which turns the toothed gear 12. This gear is responsible for turning movement 9 of the blade I through the balljoint with hub 23, as shown in Fig.10.

The combination of these three movements determines the trajectory 2 of the blade 1, as shown in Fig.4.

Some possible upgrade options such as integration of the engine into the oscillation transmission, or replacement of the balljoint 23 in order to increase the angle of oscillation of the blade, as shown in Fig. I 4 Working moment when oscillation transmission tilting the blade is shown in Fig.15. The oscillation transmission housing body 17 is represented in the cutaway view.

The other transport, such an air propulsion vehicle, can be created when using different modifications of the oscillation transmission.
