Mover amphibians

 

(57) Abstract:

The invention relates to a transport machine building. The mover includes axle, two disks of elastic material and the rim of the elastic material with the blades on the outer surface forming the inner sealed chamber. The rim is made in the form of an arch with blades having convex bearing surface. Blades with convex surface are evenly spaced along the length of the rim and inside and outside of the rim, forming a series of isolated compartments. While supporting surface of the rim is made with the ability to take the form of an arc of a circle of larger diameter. The invention is aimed at reducing the hydrodynamic losses. 2 Il.

The invention relates to transport machinery, mainly for the production of amphibians.

Known propulsion amphibians, containing the Central axis, the rim with vanes on the outer surface and two disk drives forming a chamber filled with air at the required pressure (U.S. patent N 1547265, 60 F 3/00, 1925).

The disadvantage of this mover in the form of a paddle wheel blades are large hydrodynamic losses at the entrance of the blades into the water and getting out of the water and consequently pattypan) is the driver of amphibian, containing the axis, two disks of elastic material with the blades on the outer surface forming the inner sealed chamber filled with air at the required pressure. The rim is made in the shape of an arch with blades having a convex surface (application Germany N 3827804, 60 F 3/00, 1989).

The disadvantage of this mover in the form of a paddle wheel blades are large hydrodynamic losses at the entrance of the blades into the water and getting out of the water and consequently the loss of power when driving on the water.

The technical purpose of this invention is the reduction of hydrodynamic losses propulsion during movement on the water and accordingly reducing the power required for movement of amphibians.

To solve this problem is proposed propulsion amphibians, containing the shaft, two disks of elastic material and the rim of the elastic material with the blades on the outer surface forming the inner sealed chamber filled with air at the required pressure, and the rim is made in the form of an arch with blades having convex bearing surface.

The essence of the invention lies in the fact that rim is divided blades on the same compartments, allowing you to create vozdushnogo diameter.

Thus the abutment surface of the propulsion works like a caterpillar and amphibian with this thruster slides through the water with minimal hydrodynamic losses at the entrance of the blades into the water and out of water, in addition as water contacts only the perimeters of compartments inside of the rim, in which is formed an air bag, there is no suction surface of the rim to the water, which also reduces power loss when driving through water, and by increasing the speed of movement of amphibians, the propulsion is almost completely out of the water, dramatically reducing hydrodynamic resistance to movement, and hence the power consumption for the movement.

The implementation of the cross-section of the rim in the shape of an arch with a convex bearing surface ensures the rigidity of the supporting part of the propulsion and reduces the likelihood of puncture sealed chamber when moving on land.

In Fig.1 shows a General view of the proposed thruster of Fig.2 - cross section.

The inventive propulsion device includes a shaft 1, which is hermetically connected with two disks 2 of elastic material, which is hermetically connected to the rim 3 of elastic material with convex blades 4, forming an internal sealed chamber 5, which is filling the air bags when driving on water where the bearing surface of the rim 3 of the mover takes the form of an arc of a circle of larger diameter.

The thruster operates as follows: when entering water load (useful) and weight amphibians) through shaft 1 is transmitted to the rim 3, the abutment surface which takes the form of an arc of a circle of larger diameter (due to the pressure in the inner sealed chamber 5). The propulsion is partially immersed in water, as increases bearing surface and formed an air cushion in isolated compartments 6. The lower part of the rim 3 works like a caterpillar and amphibian starts to move through the water with low hydrodynamic resistance due to the gradual entry of the blades 4 in the water and out of water, and lack of wetting (suction), i.e., the entrance and exit of the blades 4 is slower than the paddle wheel of a constant diameter, as well as energy hydrodynamic resistance is approximately proportional to the cube of the speed of entry and exit of the blades 4 and decreases the power required for the movement of amphibians. The decrease in the wetting (suction) surface of the rim 3 to the water is due to the fact that water in contact only the perimeters of isolated compartments 6.

When the movement of the amphibian on land arched about who has the necessary cross amphibious cross-country.

Mover amphibians, containing the shaft, two disks of elastic material and the rim of the elastic material with the blades on the outer surface forming the inner sealed chamber filled with gas under pressure, and the rim is made in the form of an arch with blades having a convex bearing surface, wherein the rim is divided blades on the same compartments, allowing you to create an air cushion during movement on the water, where the bearing surface of the rim propulsion takes the form of an arc of a circle of larger diameter.
