HIGH-SPEED FLIGHT METHOD AND COLEOPTER

Abstract

A coleopter may have maximum lift up to tens of thousands of tons and is an optimum lift device of a disk aircraft. However, an existing coleopter may provide thrust consistent with an axial direction of the coleopter only, but cannot provide thrust perpendicular to the axial direction. Therefore, like other existing disk aircrafts, a wing ring flying saucer must be additionally provided with an aero-engine capable of specially providing thrust in a horizontal direction, otherwise cannot fly fast, while due to the extra engine, effective carrying capacity is inevitably seriously compressed, and energy consumption, pollution and noise may be increased. In the present invention, the flying saucer may be driven to fly fast without the extra engine, and can turn, brake and fly backwards. The method is as follows: fins of the wing ring or fluid generators are enabled to repeat the same deflection process while passing by a specific section in circular motions of two times or more than three times in succession, so that a force perpendicular to the axial direction is formed from an original resultant force consistent with the axial direction of the wing ring (that is, a resultant force formed by lift produced by all the fins), thereby enabling the wing ring flying saucer to fly, turn and go backwards at high speed.

PREFERRED EMBODIMENTS OF THE PRESENT INVENTION

Embodiment 1

[0076] A wing ring flying saucer is formed by connecting two wing rings shown in FIG. 2 and an annular engine room 15. A specific connection manner is shown in FIG. 1 (a disk coleopter is formed by two wing rings, two track coupling rings 44 and an annular engine room 15, and the annular engine room 15 is in dynamic connection with two wing rings 9 by virtue of two upper and lower track coupling rings 44).

[0077] In the present embodiment, the two wing rings have opposite rotation directions, the fin 9 has lift airfoil, and one upward side of the fin has a lower air pressure than one downward side during air cutting.

[0078] An engine in the present embodiment adopts a motor or an internal combustion engine. The engine is mounted at an appropriate position of an annular frame (frame ring) 40; the engine and a wheel 41 of a track car are in power connection; the wheel 41 is driven to rotate by the engine; and an annular track (track ring) 39 is driven to rotate by the wheel 41. Because the track ring 39 is fixedly connected with the wing ring, the wing ring will rotate along with the track ring 39.

[0079] The quantity of engines is determined according to power demands. Each wheel 41 may be equipped with an engine, or each wheel set is equipped with an engine, or every several wheel sets are equipped with an engine.

[0080] Key configuration is as follows:

[0081] A connection manner of each fin 9 and an annular truss 1 of the wing ring can be seen in FIG. 3 (the annular truss shown in drawings of the description; except the FIG. 2, FIG. 4, FIG. 18, FIG. 24, FIG. 26 and FIG. 27 are top views of the complete annular truss, each of the rest is a cross section of the annular truss). A lower end of a handle 9-1 of the fin 9 is in dynamic connection with the annular truss 1 by virtue of a rotating shaft B 12. The top of a hydraulic rod 10 is in dynamic connection with the handle 9-1 of the fin 9 by virtue of a rotating, shaft C 13; and the bottom of the hydraulic telescopic rod 10 is in dynamic connection with the annular truss 1 by virtue of a rotating shaft A 11.

[0082] Then, two groups of signal emitters X1 and X2 are arranged on an annular engine room 15, and specific orientations of the signal emitters are located at directions Xl and X2 in FIG. 4. The group X1 includes three signal emitters a, q and b, and the group X2 includes three signal emitters A, Q and B (shown in FIG. 5).

[0083] Meanwhile, a signal receiver is arranged on each fin 9. Tasks of the signal receivers are to receive signals transmitted thereby while passing by the signal emitters a, q, b, A, Q and B along with the fins and to transmit the signals to a control device of the motor. The control device executes a signal instruction to enable the motor to forward, reverse and stop, thereby enabling the hydraulic telescopic rod 10 to lengthen, shorten and stop.

[0084] The two groups of signal emitters X1 and X2 of the small low-speed wing ring flying saucer should be decreased by one. Since only one section of bearing capacity N remains (shown in FIG. 6 or FIG. 7), when the force N is too high, the round wing ring should be prevented from being flattened by extrusion or pull so as to avoid hindering mechanical property.

[0085] Therefore, a large or high-speed wing ring flying saucer should enable the X1 and X2 to simultaneously bear the equal force N (shown in FIG. 8). Thus, the following configuration must be made:

[0086] 1. b and B always transmit motor stop signals only, so that the hydraulic rod is maintained in an initial state;

[0087] 2. the signals transmitted by q and Q must be opposite, and the signals transmitted by a and q must be opposite, which aims to enable the hydraulic rod to change from a lengthening (or shortening) state to a shortening (or lengthening) state;

[0088] 3. the signals transmitted by q and Q must be opposite, and the signals transmitted by a and A must be opposite, which aims to enable the fins to have opposite wingspan orientations in the directions X1 and X2 (shown in FIG. 8);

[0089] 4. an initial length of the hydraulic telescopic rod 10 is a length needed for fixing the wingspan orientation at an initial angle, and an appropriate expansion quantity must be reserved, so that the hydraulic telescopic rod can stretch out when located at the initial length and can also retract when located at the initial length, and the stretch limit length is equal to the retraction limit length; and

[0090] 5. the signal receivers can receive signals transmitted from each point only when arrive at the points a, q, b, Q and B only, and then execute the instruction (not interfered by signals on other points);

[0091] A lift mechanism of the wing ring flying saucer is a coleopter, while the coleopter only can transmit upward lift. In the present embodiment, a stable component force in the horizontal direction may be obtained from the upward lift of the coleopter (force N in FIG. 6, FIG. 7 and FIG. 8).

[0092] With the above configuration, when the fin 9 passes by the point a or A, the signal receiver of the fin receives a forward or reverse instruction to enable a forward circuit or a reverse circuit to be connected, the motor rotates forwards or reversely, and the hydraulic telescopic rod 10 is, driven to lengthen or retract, so that the fin 9 warps or press downwards, a wingspan deflection angle is continuously enlarged, and the component force in the horizontal direction is continuously increased. In a similar way, when the fin 9 passes by the point b or B, the signal receiver of the fin receives a reverse or forward instruction to enable the motor to rotate reversely or forwards, and then the hydraulic telescopic rod 10 starts to retract or stretch; a wingspan deflection angle starts to continuously narrow, and horizontal thrust is continuously decreased. In a similar way, when the fin 9 passes by the point b or B, the signal receiver of the fin receives a stop instruction, the motor stops rotating, and the hydraulic telescopic, rod 10 stops; at this moment, the hydraulic telescopic rod 10 just retracts (or lengthens) to the initial length; the fin 9 just restores to an initial wingspan angle; and the fin 9 stops producing horizontal thrust. Since each fin follows up the previous fin, when the horizontal thrust produced by the previous fin is continuously decreased, horizontal thrust produced by the next fin is continuously increased. Therefore, continuous and stable power in the horizontal direction can be obtained.

Embodiment 2

[0093] On the basis of embodiment 1, two groups of symmetrical signal emitters are increased in directions Y1 and Y2 of an annular engine room 15; the configuration method is just the same as that, of two groups in the directions X1 and X2, but just the locations, are different (shown in FIG. 4). When only advancing is needed, the X1 and X2 should be started only, and the Y1 and Y2 are started when turning is needed.

Embodiment 3

[0094] On the basis of embodiment 1 or embodiment 2 the original four signal emitters a, A, q and Q capable of emitting forward or reverse signals alone in the directions Y1 and Y2 are changed into emitters that can emit both forward signals and reverse signals, and a directional control lever of the flying saucer serves as a forward/reverse signal reversing controller. When the control lever is in a vertical state, the signal emitters a, A, q and Q should stop emitting any signal, so that the fin does not deflect while passing by the directions Y1 and Y2; when the control lever is pulled to the left, a left-turning circuit should be connected, and the lower-pressure side of the fin is inclined to the left side of the original advancing direction by virtue of the signals transmitted by the a, A, q and Q (shown in FIG. 8); and when the control lever is pulled to the right, a right-turning circuit should be connected, and the lower-pressure side of the fin is inclined to the right side of the original advancing direction by virtue of the signals transmitted by the a, A, q and Q (that is, the direction of the lower-pressure sides of the two fins 9 is opposite to a direction, shown in FIG. 8).

[0095] Left turning and right turning may be easily realized in the present embodiment.

Embodiment 4

[0096] On the basis of embodiment 3, the four signal emitters a, A, q and Q in the directions X1 and X2 are configured according to the method in the embodiment 3.

[0097] When the directional control lever is pressed forwards, the low-pressure sides of the fins in the directions X1 and X2 lean forward, so the flying saucer can fly forwards; when the directional control lever is pulled backwards, the low-pressure sides of the fins in, the directions X1 and X2 lean backwards, so the flying saucer can rapidly decelerate, realize braking (hovering) in a short distance, and even rapidly change from a forward state to a reverse state (backward inverted flight on premise of not steering or turning round).

Embodiment 5

[0098] Each fin or fluid generator of each wing ring is equipped with a deflection device in embodiments 1-4. In the present embodiment, the quantity of fins or fluid generators equipped with deflection devices is decreased; and the quantity can be decreased to a minimum of 1 (when the quantity is more than one, the, fins or fluid generators are still arranged in a ring array).

Embodiment 6

[0099] Modifications are made on the basis of any of embodiments 1-4 as follows:

[0100] The original all fins 9 (and wingspan orientation deflection devices thereof) are replaced with fins (or deflection control devices thereof) of existing aircrafts with flaps, ailerons or/and slats.

[0101] The flying saucer may achieve an aim of changing the angle of attack of the fins by deflecting the flaps, ailerons or slats only. Since the angle of attack is changed on the specific section only, the wings produce lift changes on the section, so that the lift on the section is greater than or smaller than that on other sections, thereby causing slight tilt of the wing, rings. Due to tilt of the wing rings, a driving force in the horizontal direction may be decomposed from the whole lift.

Embodiment 7

[0102] Modifications are made on the basis of embodiment 1 as follows:

[0103] An original wingspan orientation deflection device is replaced with a deflection device of an existing large three-blade wind turbine capable of changing, the angle of attack of the fins. A fin angle-of-attack deflection device of the three-blade wind turbine is arranged inside an annular truss 1 of the wing ring, and the root of the fin 9 is connected with the deflection device, so that the deflection device can wholly deflect the fin 9, thereby directly changing the angle of attack of the fins and obtaining the driving force in the horizontal direction. (a principle of producing horizontal thrust in the present embodiment is the same as that in embodiment 7).

Embodiment 8

[0104] Modifications are made on the basis of any of embodiments 1-4 as follows:

[0105] A fin deflection device equipped on each fin 9 is canceled, so that the fin 9 becomes a fin 8 with a non-deflectable wingspan orientation. Moreover, a jet engine 23 is arranged at the tail, end of each fin (shown in FIG. 11), the jet engine 23 is in dynamic connection with the fin 9 by virtue of a bearing 26, and a hydraulic rod 10 is in dynamic connection with a wing ring 9 by virtue of a bearing 11 and is in dynamic connection with the jet engine 23 by virtue of a bearing 27.

[0106] Thrust produced by the jet engine 23 deviates from a tangential direction on the specific section by controlling the hydraulic rod to stretch and retract (such as a state shown in FIG. 12), thereby producing thrust in the horizontal direction. A specific principle is as follows:

[0107] In FIG. 9 and FIG. 10, the circle represents an annular truss of the wing ring, a thick solid arrow represents a direction of acting force given by a fin or fluid generator that runs to the position and deflects by an angle (if the fin or fluid generator runs to the position but does not deflect, the direction of the acting force given thereby is the same as the tangential direction of the wing ring, that is, a direction pointed by a thin dotted arrow in the figure, and thus horizontal driving force is impossible to produce), and a thick dotted arrow in the figure represents a component force of the acting force after deflection in a horizontal advancing direction of the wing ring (that is, the component converted into the horizontal driving force). A thin solid arrow in the figure represents the direction of the acting force given by the fin or fluid generator that runs to the position. Since the fin or the fluid generator does not deflect while running to the position, the direction of the acting force is the same as the tangential direction of the wing ring.

[0108] Although each fin or fluid generator during rotating does not continuously produce driving force pointing at the same specific direction, as shown in FIG. 9 and FIG. 10, since each fin or fluid generator may produce horizontal driving force pointing at the same specific direction on the same section, and such a driving force is continuously produced on the same section one by one, a continuous thrust N in the horizontal direction with stable size and direction in one specific direction is formed on the section.

[0109] Notes: FIG. 9 shows a situation of a deflection power orientation on one section only, while FIG. 10 shows a situation of a deflection power orientation on two sections simultaneously (the two paths refer to a path from the sections a to b and a path from the sections A to B as shown in FIG. 5).

Embodiment 9

[0110] On the basis of embodiment 8, the jet engines 23 and equipped hydraulic telescopic rods 10 thereof are moved onto the annular truss of the wing ring (all jet engines 23 should be arranged in a ring array).

Embodiment 10

[0111] On the basis of embodiment 8 or 9, a jet engine 23 is replaced with a propeller engine 28 (as shown in FIG. 13).

Embodiment 11

[0112] On the basis of any of embodiments 1-9, a circular central engine room 16 and four strip-shaped radial engine rooms 17 are increased, and the radial engine rooms 17 are connected from four directions and communicated with the central engine room 16 and an annular engine room 15, thereby forming a disk engine room shown in FIG. 15.

[0113] FIG. 17 is a schematic diagram of a radial section cutting plane of a wing ring flying saucer in the present embodiment.

Embodiment 12

[0114] On the basis of embodiment 11, a scale of the central engine room 16 is enlarged; the originally configured wing rings shown in FIG. 2 are replaced with wing rings shown in FIG. 18; the connection manner of deflection devices of fins 9 and the annular truss of the wing rings is identical to that in embodiment 11; and two ends of fins 8 are respectively fixedly connected with two annular trusses.

[0115] The whole radial section cutting plane is shown in FIG. 19.

Embodiment 13

[0116] On the basis of embodiment 12, the original fins 9 are canceled, so that a top view of the wing rings is as shown in FIG. 25. Two ends of each, fin 9 of the wing ring are connected with two annular trusses 1, and the connection manner is as shown in FIG. 14.

[0117] The whole radial section cutting plane in the present embodiment is shown in FIG. 20.

[0118] When horizontal flight power needs to be provided, one (or two) hydraulic rods) 10 shown in FIG. 14 is (are) started, so that the fins 9 produce wingspan orientation deflection. If the two hydraulic rods are started simultaneously, the wingspan orientation of the fins 9 may deflect faster.

Embodiment 14

[0119] On the basis of embodiment 13, the shape of the engine room is further changed, and a track coupling ring 44 is transferred, so that the annular truss 1 of the wing ring and the engine room are changed from an upper-lower connection manner to a left-right connection manner. The whole radial section cutting plane in the present embodiment is shown in FIG. 21.

[0120] The advantage of changing to the left-right transverse connection is that the weight of the track coupling ring is reduced, and the number of wheels on, each track car may be decreased from 5 to 3 (only one wheel is arranged on the upper and lower sides respectively, and one wheel is arranged on the left or right).

Embodiment 15

[0121] On the basis of embodiment 14, the weight of the flying saucer is further increased. The whole side view of the present embodiment is shown in FIG. 22, and the top view is shown in FIG. 24.

[0122] The wing ring adopted in the present embodiment is composed of two wing rings having the same center of circle and different radiuses. Rotation directions of the two wing rings having different radiuses on the same layer may be the same or opposite, while rotation directions of any two wing, rings having the same radius on different layers must be opposite.

[0123] Since the two wing rings on the same layer do not have to rotate at the same angular velocity, fins on different radiuses may obtain the same linear velocity (airspeed), thereby maximizing the whole lift and mechanical strength.

Embodiment 16

[0124] On the basis of embodiment 15, all wing rings on the lower layer and deflection devices and track coupling rings thereof are canceled, and a more flat flying saucer is obtained (shown in FIG. 23).

Embodiment 17

[0125] On the basis of embodiment 12, 13, 14 or 15, the engine room is transformed into a shape as shown in FIG. 16. The whole radial section cutting plane in the present embodiment is shown in FIG. 25.

Embodiment 18

[0126] On the basis of any of the above embodiments, waterproof sealing is performed on engine rooms, the coleopter, deflection devices and the like, so as to adapt to drop, float and submerging on the water surface (the coleopter may provide advancing power below the water and further accelerate to float or submerge).

Embodiment 19

[0127] On the basis of any of the above embodiments, the flying saucer is equipped with an annular or circular airbag so as to drop and, float on the water surface.

Embodiment 20

[0128] On the basis of embodiment 18 or 19, the jet engine is replaced with a high-pressure flow generator.

Embodiment 21

[0129] On the basis of the above embodiments, undercarriages in a ring array are arranged, and all the undercarriages are connected with an annular engine room 15, a central engine room 16 or an annular frame (frame ring) 40.

Embodiment 22

[0130] Two wing rings of the coleopter in the above embodiments are provided with fins or fluid aircraft deflection devices and corresponding signal emitting and receiving devices. In the present embodiment, the deflection devices of one wing ring and the corresponding signal emitting and receiving devices are canceled, so that only one wing ring of the coleopter has the deflection devices and corresponding signal emitting and receiving devices. Therefore, only one wing ring produces a component force in the, horizontal direction, which is enough for the coleopter of certain purposes.

Embodiment 23

[0131] As shown in FIG. 5, q is the midpoint of a section ab, Q is a midpoint of a section AB, and the two specific sections actually become a section group in midpoint symmetry.

[0132] In any of the above preferred embodiments, all the section groups in midpoint symmetry have three pairs of symmetrical points: the first pair is the starting point of the two sections, the second pair is the endpoint of the two sections, and the third pair is the midpoint of the two sections.

[0133] In the present embodiment, the length of any section in the section groups is enlarged or shortened, so that the starting points and endpoints of the two sections are asymmetrical (but the two sections are kept in midpoint symmetry).

Embodiment 24

[0134] On any wing ring flying saucer, fins or fluid generators of wing rings are set to repeat the same deflection process, while passing by a specific section each time in circular motions of two times or more than three times in succession by adopting the method in preferred embodiments 1-9.

Embodiment 25

[0135] On any wing ring flying saucer, the top view of wing rings (annular rotors, annular propellers, or annular wind wheels) is shown in FIG. 27, and the side view is shown in FIG. 28. Since lower-pressure sides of lift wings are inclined to the axis (wings that produce lift during air cutting), force pointing at the center of the wing ring is produced.

Embodiment 26

[0136] On any wing ring flying saucer, the top view of wing rings (annular rotors, annular propellers, or annular wind wheels) is shown in FIG. 26, and the side view is shown in FIG. 29. Inclined wings have lift wings (lift is produced during air cutting, and the lift points at the axis of the wing ring).

Embodiment 27

[0137] On any wing ring flying saucer, the top view of wing rings (annular rotors, annular propellers or annular wind wheels) is shown in FIG. 26, and the side view is shown in FIG. 30. Inclined wings have lift wings (lift is produced during air cutting, and the lift points at the axis of the wing ring).

Embodiment 28

[0138] On any wing ring flying saucer, the top view of wing rings (annular rotors, annular propellers or annular wind wheels) is shown in FIG. 26, and the side view is shown in FIG. 31. Arc-shaped wings have lift wings, and lift of warping wing panels points at the axis of the wing ring.

Embodiment 29

[0139] On any wing ring flying saucer, wingspan orientations of wing rings (annular rotors, annular propellers or annular wind wheels) point at fins parallel to the axis of the wing ring, and the lower-pressure side of the fins is aligned at the axis of the wing ring (the chord line is parallel to a circumferential tangent of the wing ring). Not less than 3 fins are arranged on one circumference of the same wing ring at least, and the distance between every two fins on the circumference is equal.

[0140] The lower-pressure side of the fin refers to one side with a lower air pressure in two sides of the fin during air cutting by the fin.

Embodiment 30

[0141] For any disk aircraft taking wing rings (a coleopter, an annular propeller or an annular wind turbine) as a lift device, one end with smaller wing chords on all the fins of the wing ring face the axis direction (as shown in FIG. 24 or FIG. 26).
