Description

  The present invention relates to a flying object that floats and flies in the atmosphere, and relates to an invention that can be applied to toys in addition to manned aircraft and unmanned aircraft.

  A conventional flying object moves up with the thrust of a propeller, jet engine, rocket engine, etc., and moves the wings relative to the atmosphere, creating a flow of air that generates lift on the front and back of the aircraft. . Therefore, it is necessary to always move forward in order to obtain lift, and it is impossible to stop and hover in the air except for a special case.

  On the other hand, the helicopter moves by moving the wing relative to the atmosphere by rotating the wing, thereby generating lift and rising. Therefore, it can be stopped and hovered in the air, but the rotor blade is much larger than the fuselage and rotates outside the fuselage, so the rotor blade is unprotected against external obstacles and may be damaged, restricting the use environment There was a problem that was easy to receive.

  On the other hand, in order to solve the above-mentioned problems, a flying object equipped with a plurality of rotor blades in the upper projected contour line of the airframe has been proposed (Patent Document 1).

  In addition, an invention has also been proposed that intends to float by providing a blower that blows air in the centrifugal direction at the center of a ring-shaped blade (Patent Document 2). This invention has a ring-like wing, and presupposes the principle of generating lift by generating an air flow in the ring-like wing by blowing air radially from a blower that blows in the centrifugal direction toward the ring-like wing. Yes.

  However, in the flying body described in Patent Document 1, there is a problem that the size of the rotor blade is restricted in order to be accommodated in the airframe, and sufficient lift cannot be obtained unless a high-power engine is used.

  On the other hand, in the flying body described in Patent Document 2, it is assumed that the blower placed in the center of the ring-shaped wing takes air from the upper center or the vertical direction of the center and blows it radially toward the ring-shaped wing. Therefore, the wing communicates with the air above the wing in the central hole, and the lift is canceled by taking in from below the blower. That is, even if lift is recognized when the aircraft is fixed at a fixed position, in the state where a load is actually applied to the aircraft, the airflow is only the amount of the load from the gap between the blower and the center hole of the wing. Even if the blade crosses away in the reverse load direction and the blade cross section generates lift as a result, the air blown from the upper side of the blower escapes to the blade upper surface by the amount of the load, so that the levitation is not suitable.

The present invention was created for the purpose of providing a flying body that solves the above-mentioned problems, and is supplied by an upper blower composed of rotating blades that pump air in an axial flow direction and the upper blower. The lower blower composed of rotating blades for pumping the air in the centrifugal direction is arranged coaxially so as to rotate in opposite directions, and at least the inner surface where the blower is arranged concentrically forms a conical surface. It consists of a skirt-shaped fixed wing, and a lower blower is suspended from the inner upper part of the fixed wing so that air blown in the centrifugal direction collides with the conical surface of the fixed wing. In a flying vehicle that is closed except for the axial flow path that is pumped from the upper blower to the lower blower , one of the rotating blades of the upper blower is closed, and the other is a two-piece with a through hole in the center. Between the discs In the turbo fan on the upper air blower side, the through hole of the turbo fan on the upper air blower side and the through hole of the turbo fan on the lower air blower side are arranged coaxially facing each other. The air sucked from the centrifugal direction is pumped in the axial direction through the through hole, and in the turbo fan on the lower blower side, the air sucked through the through hole is rotated in the opposite direction so as to be pumped in the centrifugal direction. characterized in that the.

  According to the present invention having the above-described configuration, first, the air pressure-fed in the centrifugal direction collides with the inner conical surface of the fixed wing, so that the pressure difference between the fixed wing and the outside due to the air flow. Is generated and lift is generated. In this case, the upper portion of the fixed wing is closed except for the axial flow passage that is pumped from the upper blower to the lower blower, and the air flows downward from the upper blower from the axial flow passage. Therefore, as in the flying body described in Patent Document 2, the airflow escapes in the reverse load direction as much as the load, and the lift is not canceled out.

  Second, the air pumped in the centrifugal direction collides with the inner conical surface of the fixed wing, so that the airflow is deflected obliquely downward depending on the inclination angle, and stress is obtained, and this stress raises the flying body. It becomes a thrust. Also, in this case, the rotating blades of the lower blower are arranged concentrically with the skirt-shaped fixed wing whose inner surface forms a conical surface, so that they are pumped in the centrifugal direction and collide with the inner conical surface of the fixed wing. The reaction force gathers on the shaft and causes an action to cancel each other.

  Thirdly, since the upper blower device and the lower blower device, which are composed of rotating blades, are arranged on the same axis so as to rotate in opposite directions, the torque is canceled and the fixed blade is prevented from rotating.

  Fourthly, since air is not pumped directly under the lower blower that collides the air pumped in the centrifugal direction with the conical surface inside the fixed wing, the cargo space, passenger compartment, etc. It can be suspended.

  Fifth, the fixed wing that also serves as the airframe of the flying body is a skirt shape whose inner surface forms a conical surface, so that the wing moves relative to the atmosphere by moving in a plane direction, and lift is applied to the front and back. A generated air flow is generated.

  The flying object of the present invention has a fixed wing that does not have a rotor wing and also functions as a fuselage and floats in the air by generating lift inside it, and also flies by controlling its direction, so it landed in a place with many obstacles It becomes possible to do. For example, it can float on a high-rise building or the like while the aircraft is in contact with it, so it can be used for rescue in the event of a fire. Also, in flying and flying, the fixed wing is a form of an all-wing aircraft that also serves as a fuselage, and it can cope with overflow problems caused by complicated shapes by not having several wings, and it is necessary for takeoff and landing Airfield area can be saved. On the other hand, when implemented on a toy aircraft, there are no rotating propellers or rotor blades, which can prevent accidents and injuries.

  Hereinafter, specific embodiments of the flying object of the present invention will be described with reference to the accompanying drawings. 1 to 4 are views showing an embodiment of a flying object of the present invention. Reference numeral 1 in the figure denotes a fixed wing that also serves as an aircraft body. The fixed wing is required to have a skirt shape in which at least the inner surface forms a conical surface T. Here, the upper portion is formed in a truncated cone shape that forms a flat top plate 3.

  Next, reference numeral 10 in the figure denotes an air blower, which is composed of an upper air blower 11 comprising rotary blades that pump air in the axial direction, and a rotary vane that pumps air pumped from the upper air blower in the centrifugal direction. It consists of the structure which has arrange | positioned coaxially so that the lower air blower 21 may rotate in a mutually reverse direction (refer FIG. 3, 4). In this embodiment, the upper air blower 11 is a turbo fan in which a blade 15 is provided between a closed disc 13 and a disc 14 having a through hole 12 in the center, and a lower plate 23 in which the lower blower 21 is also closed. And a turbo fan in which a blade 25 is provided between a disc 24 having a through hole 22 in the center. These are configured in the same phase, and the through holes 12 and 22 face each other on the same axis and are rotated in opposite directions, so that the turbo fan on the upper blower 11 side sucks air from the centrifugal direction. Air is pumped in the axial direction through the through hole 12, and in the turbofan on the lower blower 21 side, the air sucked in through the through hole 22 is pumped in the centrifugal direction.

  In the above air blower, the upper air blower 11 and the lower air blower 21 are distributed inside and outside the upper portion of the fixed wing 1. That is, the upper air blower 11 is erected on the upper side of the top plate 3 of the fixed wing 1 so as to be rotatable, and the lower air blower 21 is hanged on the lower side of the top plate 3 so as to be rotatable. In this case, the top plate 3 of the fixed wing 1 must be closed except for the axial flow passage D that is pumped from the upper blower 11 to the lower blower 21 via the through holes 12 and 22 (see FIG. 1).

  The air pumped from the lower blower 21 must be blown only in the centrifugal direction, and the pumped air collides with the conical surface T inside the fixed wing 1 as shown by the arrows in the figure. As a result of the air flow, an air pressure difference is generated between the fixed wing and the outside, and lift is generated, and the airflow is deflected obliquely downward depending on the inclination angle, thereby obtaining a stress that is a thrust force that raises the flying object. On the other hand, in the upper air blower 11, there is no particular restriction on the air intake direction, but in this embodiment, a room 4 in which the upper air blower is accommodated is provided on the top plate 3 of the fixed wing 1, and the periphery of this room is By providing a vent hole 5 on the side, air is sucked from the circumferential direction.

  The air blower 10 described above may be driven by an internal combustion engine or a motor, or may be jet driven by providing a combustion device between the axial flow passages D to be pumped.

  In this embodiment, the lower end 2 of the fixed wing 1 is not diffused in the circumferential direction but is folded in the vertical direction. With such a configuration, it is deflected obliquely downward depending on the inclination angle of the inner surface of the fixed wing. The airflow can be further guided directly below, and the thrust efficiency can be increased.

  In the above aircraft, ascending lift and thrust in the vertical direction can be obtained as described above, but in order to obtain the thrust in the horizontal direction, a thrust generator such as a propeller or a jet engine is separately provided. You may carry out by making the fixed wing | blade 1 incline. 5 to 8 show examples of means for that purpose.

  FIG. 5 is a diagram showing an example of a means for obtaining a thrust in the horizontal direction by tilting the fixed wing by changing the balance of the center of gravity of the fixed wing 1. Here, the balance device 30 in which the weight 31 can move in the circumferential direction is provided at a plurality of locations (three locations here) on the circumference of the fixed blade 1, and the balance of the center of gravity is changed by changing the weight position in each balance device. Is changing.

  FIG. 6 is a view showing an example in which the fixed blade is inclined to obtain a thrust in the horizontal direction by changing the balance of air colliding with the conical surface T of the fixed blade 1 from the lower blower 21. Here, the balance of the air which collides with the conical surface of a fixed wing | blade from a lower air blower is changed by arrange | positioning the undulating diffuser 40 in the arbitrary places (here 3 places) of the conical surface T of the fixed wing | blade 1. Yes.

  FIG. 7 is a diagram showing a different example when the means for obtaining the thrust in the horizontal direction by tilting the fixed wing by changing the balance of the air colliding with the conical surface T of the fixed wing 1 from the lower blower 21 is shown. is there. Here, the balance of the air which collides with the conical surface of a fixed wing from a lower air blower is changed by arrange | positioning the through-hole 50 which can be opened and closed arbitrarily in the conical surface T of the fixed wing | blade 1 (here 3 places). ing.

  FIG. 8 is a diagram showing a different example in the case where the means for obtaining the thrust in the horizontal direction is obtained by inclining the fixed wing by changing the balance of the air colliding with the conical surface T of the fixed wing 1 from the lower blower 21. is there. Here, the balance of the air which collides with the conical surface of a fixed wing from a lower air blower is changed by making the conical surface T of the fixed wing | blade 1 flexible in arbitrary shapes. That is, here, the flexible portion 60 that expands and contracts in the axial direction on the inner periphery of the fixed wing 1 is arranged in a band shape so that an arbitrary portion on the circumference is expanded and contracted. The expansion / contraction is performed by expanding / contracting the hollow portion 61 of the flexible portion 60 by moving the cam or filling the fluid.

  This invention which consists of the above structure can be implemented not only on manned aircraft and unmanned aircraft, but also on toy aircrafts. Moreover, when it implements to a manned machine and an unmanned aircraft, as shown in FIG. 1, the passenger | crew's room or the luggage compartment C can be suspended below the lower air blower 21 in the fixed wing | blade 1.
