The device can be widely applied to any equipment, needing to reduce resistance when running in fluid, such as an airplane, a missile, a train, a car, a steamship, a submarine and the like.

Description

A kind of traffic tool resistance reduces device

Affiliated technical field

The present invention relates to a kind of traffic tool resistance and reduce device, especially be installed in one group of blade of traffic tool fronts such as car, ship, aircraft, submarine, when the traffic tool advance, rely on the relative movement of fluid to make blade obtain the energy rotation, change a kind of device that the fluid motion direction reduces fluid resistance.

Background technique

At present, the traffic tool move in fluid can be subjected to resistance, such as train, automobile, the traffic tool such as aircraft are when operation, greatly power is to be used for overcoming resistance in fluid, in order to reduce resistance, people make the traffic tool streamlined as far as possible, but also be merely able to reduce some resistances, when traffic tool high-speed motion, the resistance of fluid is very big, overcome this resistance to needs with most of power greatly, one with 100 kilometers traveling automobile per hour, engine output 80% is used to overcome resistance of air, as long as reduce resistance of air, just can effectively improve the Economy of automobile running, the speed that the traffic tool travel is big more, motor will be used more output power and overcome this resistance, aircraft is all the more so, just can save the energy than slight drag, therefore, how reduce the resistance of the traffic tool in travelling, just become the focus that people pay close attention to, also be a difficult problem simultaneously, so up to the present, also do not have a kind of device that reduces traffic tool front resistance of whose specialized designs.

Summary of the invention

In order to reduce the resistance of the existing traffic tool in travelling, the invention provides a kind of traffic tool resistance and reduce device and solve this problem, to improve traffic tool economic performance under steam.

The technical solution adopted for the present invention to solve the technical problems is:

At automobile, train, aircraft, the free rotating blades of energy that one group of relative fluid motion that produces drives is adorned in the front of traffic tool heads such as submarine when the traffic tool move, this blade and blade of wind-driven generator, fan blade is similar, it is vane thickness, length, width, radian, parameters such as angle design according to the concrete traffic tool, with wind-driven generator and some difference of fan blade, but principle is similar, the multi-disc blade pass is crossed the blade connecting body and is linked together, be that blade is evenly distributed on around the blade connecting body, axle one end connects the blade connecting body, the other end connection bearing, the appropriate location of bearing fixing in traffic tool head, the difference of the blade of blade of the present invention and wind-driven generator is, blade of wind-driven generator need be with generator to rotate generating, and blade of the present invention does not need to be with other loads outward except the fluid that rotates traffic tool front, in order to reduce resistance, the angle in blade and axle center is any acute angle, and angle is determined according to the concrete traffic tool.

Embodiment

In the embodiment of Fig. 1, Fig. 2, we are that the present invention is further described for example to realize that a kind of traffic tool resistance reduces device:

In Fig. 1, traffic tool head 6 fronts are equipped with multi-disc blade 2, the quantity of blade 2 is three among the figure, minimum can be with two, also can be with four etc., for convenience of description, be commonly referred to as multi-disc more than or equal to two, multi-disc blade 2 links together by blade connecting body 4, forms the structure that is equivalent to windmill or electric fan, rotating shaft 3 one ends are connected with blade connecting body 4, and the other end and bearing 5 connect together.Blade 2, blade connecting body 4, the integral body that rotating shaft 3 is formed can freely be rotated, when the traffic tool such as moving direction 9 indicated directions are advanced, fluid forms streamline 8, according to relative motion principle, if the traffic tool 1 are treated as reference system, fluid motion so, the traffic tool 1 move soon more, being equivalent to fluid motion must be fast more, and the fluid of high-speed motion acts on the blade 2, makes blade 2 high speed rotating, the fluid that blade 2 high speed rotating drive traffic tool head 6 fronts rotates together, air is thrown toward blade 2 edges under the action of the centrifugal, and the pressure that makes traffic tool head 6 be subjected to the front bump of fluid alleviates greatly, and the resistance that is equivalent to advance reduces, the power that consumes just reduces, reached the purpose of energy saving, the angle 10 in blade and axle center is preferably acute angle, to reduce fluid resistance.

In Fig. 2, the head front of the traffic tool 1 is equipped with multi-disc blade 2, the quantity of blade 2 is three among the figure, the structure of the windmill that is equivalent to wind-driven generator that multi-disc blade 2 is formed, the blade of electric fan, multi-disc blade 2 connects into an integral body by blade connecting body 4, blade 2 arranges evenly that around blade connecting body 4 blade 2 can freely rotate.

In reality is implemented, though the problem that the present invention will consider is a lot, but can determine the parameter of blade according to the kind difference of the traffic tool, must just can reach the effect that reduces resistance according to concrete traffic tool optimal design to concrete parameter such as the sheet number of blade, size, angle, radian.

The present invention is applied to aircraft, the traffic tool that the magnetic suspension train uniform velocity is very high, because the motion speed of these class traffic tool is very high, one with 1000 kilometers airline carriers of passengerss that cruise per hour, it is with respect to the speed of air 280 meter per seconds slightly, considerably beyond the speed of 17 grades of typhoon 56.1-61.2 meter per seconds, and such wind blade, it is high that the rotating speed of blade will reach, this just requires the sheet number of blade can not be too many, and blade can not be too wide, and intensity must be enough.

The present invention is applied in common train, automobile, requirement of strength to blade is more much lower aboard than using, one with 120 kilometers/hour traveling automobile, speed air flow is just worked as mutually in 12 grades of typhoons relatively, this speed is relatively littler to the intensity that blade requires, compared with the blade of using aboard, the design of this blade is just much simple, because blade is freely to rotate, main consideration blade is subjected to centrifugation effect, the sheet number of blade can suitably be added, and width can suitably increase, and must consider that simultaneously the general-utility car front installs one group of blade, can affect one's power of vision during blade rotation, can be by the purpose that reduces blade dimensions, reach not affect one's power of vision, just effect is slightly poor.

The present invention is applied to marine communication means such as warship, ship, can consider above water, underwater portion simultaneously, is necessary to load onto two groups of blades, and one group waterborne, one group under water.

The present invention also can expand the front end that is used for shell in addition, reducing the operating resistance of shell, so long as relate to the object that in fluid, moves, and resistances that can use the present invention to reduce to advance all.
