Abstract

The invention provides an engine device using electromagnetism to drive a propeller. Under the actions of a special rail varying orbit and a magnetic levitation engine, the engine of the invention can change the direction of the thrust airflow rapidly. The blades of the propeller is connected with a round inner circle orbit (a) by the magnetic levitation principle, and uses the magnetism as the power to drive the propeller to rotate based on the magnetic levitation principle. The round inner circle orbit (a) is connected with a round middle circle orbit (b) through two end bearings (m, n), the plane in which the round inner circle orbit (a) is positioned takes the line in which the two end bearings (m, n) are located as the axis to rotate. The round middle circle orbit (b) is embedded in a round outer circle orbit (c) to do concentric circle relative motion.

Description

Omnibearing electromagnetic propeller engine

Affiliated technical field

The present invention relates to a kind of engine device, realize that by special guide rail the thrust of propeller cavitation is rotated to any direction by the Electromagnetic Drive propeller cavitation.

Background technique

At present, the practical application of magnetic suspension principle in real productive life more and more widely, relevant technology (fluid mechanics, materials science) is also more and more ripe.

Simultaneously, known airscrew engine is by a transmission device as driving force at center, gives propeller cavitation with the power transmission that derives from motor, and then produces the propelling air-flow to fixed-direction.Realizing the change of propeller cavitation propulsive gas flow path direction, need locomotor (for example, the osprey fighter of U.S.'s development) simultaneously, is that transmission shaft is made complicated transmission device (for example Jue Daduoshuo helicopter) at propeller center perhaps.But, because motor itself is bulky, adding the centrifugal force that propeller cavitation produced that runs up, first kind of scheme is not only clumsy, and consumes a large amount of energy; Second kind of scheme technology is very ripe, but since the complexity of transmission hinge than higher, it safeguards relatively complicated, and the angle that the propelling air-flow that produces of propeller cavitation can move is also relatively limited.

In order to overcome can not the follow one's bent deficiency of sense of rotation of existing propeller driving device, the invention provides a kind of novel airscrew engine and covert structure, this structure combines a kind of novel airscrew engine of generation with magnetic-levitation principle and airscrew engine, this airscrew engine not only can produce at arbitrarily angled any direction and advance air-flow, and can change the direction of air-flow fast.

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

At first, the periphery in the formed circular section of propeller blade is provided with three layers of concentric circular tracks from inside to outside:

As shown in Figure 1, track a is circular inner orbit, and track b is that circular mesosphere track links to each other with track a with bearing n by bearing m, and track c is the circular skin track, and track b embeds in the middle of the track c

Outermost one deck track c is a fixed structure, is used for whole device is fixed in one plane,

Middle one deck track b is embedded among the track c, and track b can do the same plane of 360 degree concentric circle with respect to outermost orbit c and rotate in track c.

Circular inner orbit a, this layer track links to each other with intermediate orbit b by pair of bearings bearing m, bearing n, and track a can be an axle with the straight line that bearing m and bearing n are constituted with respect to mesosphere track b, does the intersection of 360 degree and rotates.

Secondly, circular inner orbit a is the drive unit that utilizes the propeller cavitation of electromagnetic suspension principle.The terminal electromagnet that adopts variable current control of installing of propeller blade, circular inner orbit a is made of the electromagnet array, the propeller blade end is suspended on the track or between, the blade end is under the control of variable current simultaneously, by driving from the repulsion between the electromagnet of electromagnet in circular track a track of propeller cavitation end, rather than from the central actuating shaft of traditional propeller, the FREQUENCY CONTROL that the realization of blade speed change changes via electromagnet pole.

The present invention has proposed two kinds of schemes for the electromagnetic actuator device of propeller cavitation end

First kind of structure: the end of propeller blade can be suspended in the middle of the track of fluted body structure;

Second kind of structure: also can be in the middle of the propeller blade end of fluted body with track suspended.

For first kind of structure, because the electromagnet quantity that track adopts is more relatively, the weight of planting structure with respect to the is bigger, but the track structure rigidity is better, is applicable to large-scale flight apparatus.

It is many that the electromagnet quantity that second kind of structure adopts will be lacked, and relative weight is lighter, is applicable to light-dutyly, and apparatus flexibly flies.

The invention has the beneficial effects as follows, drive propeller cavitation and produce when advancing air-flow, change the direction that advances air-flow to any direction fast, simple in structure.

Track a is circular inner orbit, and track b is that circular mesosphere track links to each other with track a with bearing n by bearing m, and track c is the circular skin track, and track b embeds in the middle of the track c

Innermost layer track a, this layer track are by pair of bearings, and bearing m bearing n links to each other with circular mesosphere track b, and track a can be an axle with the straight line at bearing m and bearing n place with respect to mesosphere track b, does the intersections rotations of 360 degree.

In Fig. 1 b, the relative and track b of track a, the straight line that is constituted with bearing m and bearing n is an axle, does the rotation that 360 degree intersect at track b plane; Track b is axle (as shown in the figure) with the Z axle perpendicular to track b plane, does 360 degree that are parallel to track c and rotates, and this shows the round plane that track a is constituted, and can do rotation to any direction at three dimensional space

Among the inner orbit a in Fig. 1 a, represented four propeller blades with two intersecting straight lines, in actual production, blade quantity can be 2, and 4,8 to more.

Among Fig. 2, the structure of the relative position of a kind of propeller cavitation end and track a has been described
