Definitions
- the invention relates to devices for converting mechanical energy in a fluid medium, in particular liquid and gas, and can be used as propellers and propellers of engines and propulsors of ships, aircraft (airships), wind turbines, domestic fans and other household appliances: toys and other items.
- Multiblade screws with saber-shaped blades fixed cantilever are currently considered the most effective.
- the loose ends of the blades are bent back with respect to the direction of rotation and with respect to rotation planes [Copyright certificate N ° 1711664, IPC
- the technical result is to simplify the manufacturing technology of the propeller blades, reduce the size of the blades and, accordingly, their metal consumption while increasing the thrust created by them without reducing strength and efficiency.
- the propeller (option 1) containing saber-shaped blades, the initial sections of which are fixed on the hub of the drive shaft, it is new that the propeller has at least two blades, the initial section of each blade has a direct saber, in which the front the blade edge is bent backward with respect to the direction of rotation and with respect to the plane of rotation, and smoothly passes into the final section of reverse saber, in which the front edge of the blade is bent forward with respect to the direction of rotation and with respect to the plane of rotation, while the blades are located along the axis propeller and fastened with end sections to form an axisymmetric figure.
- the propeller In the propeller (option 2) containing saber-shaped blades, the initial sections of which are fixed on the hub of the drive shaft, it is new that the propeller has three or more blades, the initial section of each blade has a direct saber, in which the front edge of the blade is bent back relative to the direction of rotation and with respect to the plane of rotation, and smoothly passes into the final section of the reverse saber, in which the front edge of the blade is bent forward with respect to the direction of rotation and with respect to the plane of rotation, the blades are located along the axis of the propeller and are fastened with end sections to form an axisymmetric figure , while the initial and final sections of each blade are fixed at predetermined angles of attack.
- the final sections of the blades are connected to each other by means of an annular nozzle.
- the angle of attack of the initial section of each blade is greater than the angle of attack of the final section of the corresponding blade, and for the mover, the angle of attack of the initial section of each blade is smaller than the angle of attack of the final section of the corresponding blade.
- the set of trajectories of the outer edges of the blades forms a swept surface, mainly oval, elongated along the axis of the propeller.
- a propeller (option 3) containing saber-shaped blades, the initial sections of which are fixed on the hub of the drive shaft, it is new that the propeller has two blades, the initial section of each blade has a straight saber, in which the front edge of the blade is bent back with respect to the direction of rotation and with respect to the plane of rotation, and smoothly passes into the final section of the reverse saber, in which the front edge of the blade is bent forward with respect to the direction of rotation and with respect to the plane of rotation, the blades are located along the axis of the propeller and are fastened with end sections with the formation of an axisymmetric figure, while the end sections of the blades are conjugated as a whole to ensure a smooth transition between the surfaces of both blades so that both blades form a single one-sided surface with a single bend, while the surfaces of the initial and final sections of each blade at the attachment points are deployed with respect to 90 degrees to each other, and the axis of the propeller and the surface of the end sections of both blade
- the set of trajectories of the outer edges of the blades forms a swept surface, mainly of an oval rotation, elongated along the axis of the propeller.
- the end portions of the blades are connected to each other directly, or the end portions of the blades are connected to each other by means of an annular nozzle or drive shaft.
- the development of the propeller blades is characterized in that the set of propeller blades is a single, solid, flat figure, consisting of at least two spiral elements, forming a symmetrical figure with one or more holes for the landing size of the hub of the propeller drive shaft.
- Spiral elements have axial holes for the landing size of the hub of the propeller drive shaft. Spiral elements have openings at open ends for the landing size of the hub of the propeller drive shaft.
- a scan consisting of two spiral elements is a two-focal spiral symmetrical with respect to a line perpendicular to the tangent to the edge of a flat figure in its middle part, with openings at open ends for the landing size of the hub of the propeller drive shaft.
- figure 1 shows a three-bladed propeller
- figure 2 is a view of a three-bladed propeller along the axis.
- figures 3 to 6 two-bladed propellers of different types of combining the ends of the blades are shown.
- figure 7 is a view of a two-bladed propeller on the axis.
- Figures 8 to 12 show examples of flat reamers of propeller blades in both of its variants.
- the proposed propeller for engines and propulsors of a fluid medium contains a hub 1 with a drive shaft 2, a fixing screw 3 and a saber-shaped blade 4.
- a hub 1 or blade 4 with an axial bore 5 is mounted on the shaft 2 with direct saber-shaped shape at the initial section 6 of the blade 4 and the angle of attack ⁇ .
- Direct saber is characterized by the fact that the front edge 7 of the blade 4 is bent back with respect to the direction of rotation and with respect to the plane of rotation and corresponds to the traditional manufacture of saber-shaped blades.
- the initial straight saber section 6 smoothly transitions to the final reverse saber section 8, that is, by providing a shape of the blade 4 in which the leading edge 7 of the blade 4 is bent forward with respect to the direction of rotation and with respect to the plane of rotation (figures 1 and 2) .
- the blades 4 with their final sections 8 are rigidly connected to each other in any known manner, providing an angle of attack ⁇ of the final sections of the blades not equal to the angle of attack ⁇ .
- the initial sections of the blades based on technological capabilities (threaded connection through holes 9 at the ends of the blades 4; welding; riveting; using an auxiliary ring nozzle 10).
- the initial sections 6 of the blade 4 with holes 5 are mounted on the hub 1 and secured with a screw 3.
- the surfaces 12 of the blades 4 at the attachment point on the hub are perpendicular to the axis of the propeller.
- the surfaces 13 of the blades 4 at the point of attachment between them are rotated 90 degrees with respect to surfaces 12, are in the same plane with the axis of the propeller and are rigidly connected to each other with the formation of an axisymmetric figure.
- the surface 13 of the blades 4 are superimposed and interconnected by spot welding (figures 3, 7).
- the bonding of the end sections of the 8 blades 4 provides a rigid and durable structure, including the use of thin steel sheet material, plastic, composite materials.
- the shape of the blades 4 with a smooth transition between their surfaces smoothly changes the angle of attack and resistance of the incoming fluid flow from maximum to minimum at the ends of the blades 4. This redistribution of the flow provides an increase in efficiency over a wide range of speeds in comparison with known devices of the same purpose.
- the end sections 8 of the blades 4 can be fixed using an annular nozzle 10 or an extension of the shaft 11 along the axis of the propeller, which facilitate access to the fastening of the blades 4 on the hub 1.
- the size of the fasteners does not change the aerodynamics of the blades (figures 4, 5).
- both propeller blades 4 can be obtained by bending one flat spiral part with holes at the ends to fix the part on the hub 1 with the formation of two blades 4 (figure 6).
- a clear explanation of the design of such a blade 4 is a flat scan in figures 8 and 9.
- the flat figure consists of two spiral-shaped elements forming an axisymmetric figure with holes 5 at the open ends of the spiral-shaped elements for the landing size of the hub 1 of the propeller drive shaft 2.
- the figure 9 shows a flat scan of a two-bladed propeller, consisting of two spiral-shaped elements of the two-focus spiral type, symmetrical about a line perpendicular to the tangent to the edge of the flat figure in its middle part, with holes 5 at the open ends of the spiral-shaped elements for the fit size of the hub 1 of the drive shaft 2 of the propeller .
- a similar propeller design can be obtained from a flat part having a scan shown in figure 10.
- the scan consists of two spiral-shaped elements forming an axisymmetric figure with axial holes 5 for the mounting size of the hub 1 of the drive shaft 2 of the propeller, and the holes 9 at the ends of the figures serve for fastening the final sections of the blades 4 with each other.
- the spiral surface of the blade 4 provides: the shape of the blades with a smooth change in the angle of attack; structural strength of the blades; reducing the dimensions and mass of the propeller while significantly increasing the efficiency and ensuring virtually silent operation; the diameter of the swept surface decreases.
- the end sections of the blades 4 are also combined coaxially near the axis of the propeller by means of an annular nozzle 10, which, on the one hand, facilitates access to the fastening means of the hub 1 (figure 2), on the other hand, its application does not practically change the aerodynamics blades 4, and also allows you to fix the end sections of 8 blades 4 at a certain angle of attack, the choice of which is in accordance with generally accepted practice.
- a three-bladed propeller taking into account the type of energy conversion, for example, from a blade 4 to a shaft 2 like a wind turbine or when transmitting rotation to a blade 4, can have an angle of attack ⁇ > ⁇ or ⁇ > ⁇ , where ⁇ is the angle of attack of the initial section 6 of the blade, and ⁇ is the angle of attack of the final section 8 of the blade 4.
- the propeller works as follows.
- the sections 6 of the direct sweep of the blades 4 begin to interact with the fluid, in which the angle of attack is less than that of the sections 8 of the reverse sweep ( ⁇ ⁇ ). Due to this, a smooth acceleration of the surrounding fluid takes place, which gains maximum speed only at the outlet of the device at the ends of the blades 4.
- the set of trajectories of the outer edges of the blades 4 forms, mainly, an oval figure elongated along the axis of the propeller. The greater the elongation of the propeller along the axis, the more smooth acceleration of the medium is carried out by the propeller.
- the design is quite light and rigid, despite the large elongation along the axis of rotation O-O ', which provides a small distributed pressure gradient in the fluid medium, and, consequently, a small level of noise, cavitation and turbulence, which significantly increases the efficiency and positively affects the overall technical efficiency of the proposed device.
- Propellers can be made by any known technological method, for example, casting, forging.
- a lightweight three-blade propeller can be bent from a flat thin sheet material, for example, steel (figures 11, 12), in the form of a part, which is a single, solid, flat figure consisting of spiral elements, forming an axisymmetric figure, with one axial hole 5 for the landing size of the hub of the propeller drive shaft and mounting holes 9.
- the Archimedean spiral As forming spirals, the Archimedean spiral, hyperbolic and logarithmic spirals, involutes, cycloids, and other suitable curves can be used, which are selected depending on the specific purpose of the proposed device.
