Description

  The present invention relates to the structure of a small flying object.

  In recent years, many ideas and inventions have been made in order to realize the flight of a passenger by a small flying object. However, a small flying body that can withstand practical use has not been put into practical use. The present invention is carried out for the purpose of suggesting a lightweight and highly reliable structure of a small flying object by simplifying the structure of the flying object and enabling easy flight.

  Propellers directly connected to the prime mover are provided, and those provided at both ends of the structure are used as the basic structure. The prime movers provided at both ends of the basic structure may rotate in the same rotational direction or in opposite directions. When combining the basic structures, the number of combinations with different rotational directions should be the same.

  Since the flying object can freely change the combination of the basic structures according to the loaded weight or the crew, any flying object can be configured. Thereby, a safe, reliable and economical flying object can be realized. The flying object is controlled by moving the center of gravity of the passenger and necessary equipment and adjusting the motor output.

  The object is to propose a small flying body that can be manufactured at a low cost and with a simple structure as much as possible, and that achieves high reliability, safety and maneuverability.

  As an example of the present invention, a small flying object that flies by rotating propellers each provided with a plurality of prime movers at the distal end portion of an airframe component that has an X-shaped basic structure. The propellers located in the diagonal direction have the same rotation direction, and adjacent propellers rotate in the opposite direction. For this reason, the basic structure is combined so that the propeller pitch is the same in the diagonal direction and the adjacent propellers have opposite pitches to generate buoyancy in the flying object. In the present invention, in order to simplify the structure and improve the reliability, the propeller pitch is fixed and directly coupled to the prime mover. Each prime mover is provided with an operation unit that can finely adjust the number of revolutions independently, and can be arbitrarily operated by a passenger. The occupant gets on a hammock-like or swing-like seat connected to a suspending device that is fixed so as to be freely swingable provided at a center of gravity of the body structure or a point close thereto. A control stick for controlling the attitude of the aircraft is fixed to the aircraft structure. The control stick is provided at a position where it is easy for the operator to operate. Accreting feet are provided in the vicinity of each prime mover in the cross member, and a shock absorber for reducing impact at landing is incorporated in the landing feet. The control stick is equipped with a grip to adjust all the prime mover outputs simultaneously and to the same extent. The axis of the grip is provided in a direction parallel to the control stick, and the axis of the adjustment group of the motor output is provided in a direction parallel to the occupant, that is, perpendicular to the flight forward direction.

  When the throttle grip part is rotated, all the prime mover outputs can be finely adjusted, so that the lift is adjusted. For this reason, the position in the height direction of the airframe can be controlled. The T-shaped grip attached to the control stick attached from the airframe to the ground is configured to be rotatable in a horizontal plane, and the horizontal orientation of the airframe, that is, yawing is controlled by rotating the grip. When the T-shaped grip is rotated in a horizontal plane, the rotational speeds of the prime mover adjacent to each other and the adjacent prime mover are adjusted to control the direction of the machine body in the yawing direction. Increase the rotational speed of the pair of prime movers rotating in the clockwise direction and the pair of prime movers rotating in the counterclockwise direction, for example, increase the rotational speed of the pair of prime movers rotating in the clockwise direction and the rotational speed of the pair of prime movers rotating in the counterclockwise direction Lower the to rotate the aircraft counterclockwise. The control in the pitch direction is controlled by moving the control stick back and forth. For example, when the control stick is pulled, the aircraft tilts forward, and when pressed, the front of the aircraft is lifted, so the aircraft moves in a tilted direction. However, since the buoyancy is reduced when tilted to a large extent, an operation to ascend is also required. The roll direction is controlled by moving the control stick left and right.For example, if the control stick is moved to the right, the aircraft tilts to the right. Conversely, if the control stick is moved to the left, the aircraft tilts to the left, so the aircraft moves in the tilted direction. do. However, since the buoyancy is reduced when tilted to a large extent, an operation to ascend is also required. When the control stick is moved in this manner, the mass of the occupant and the device attached to the occupant's seat move from the center of gravity of the aircraft, so that the position of the center of gravity of the entire aircraft changes and the aircraft can be steered.

  Flying freely in the air has been a dream of mankind for many years. In recent years, the development of aircraft is large, and those that make long-distance flight have been put into practical use and developed, but the flying object that allows individuals to fly freely has not reached the practical range. The flying object of the present invention relates to a small flying object for allowing an individual or a small number of people to fly freely. The prime mover is also a small and high-power internal combustion engine and a small high-performance electric motor that has been put into practical use. By combining these, it is possible to realize a flying object that allows an individual to fly freely. Since the attitude is controlled by moving the control stick, it is not necessary to change the pitch of the propeller, and the flight can be realized with a simple structure. Before the flight, the output of each prime mover is finely adjusted to make adjustments before takeoff so that the aircraft can fly without tilting. Altitude adjustment controls altitude by changing all prime mover outputs simultaneously. The control of yawing can be controlled by adjusting the output of the adjacent prime movers because the adjacent prime movers rotate in opposite directions to generate lift. Since the flight is controlled with such a simple structure, a highly reliable and safe flight can be realized. In addition, it contributes to the improvement of convenience by reducing manufacturing costs and downsizing.

FIG. 8 is a plan view of a combination example of basic structures.

As an example, two basic structures are combined so that the structural bodies 1 are orthogonal to each other. The prime mover 7 and the prime mover 9 are directly connected to a propeller having a pitch that rotates counterclockwise as viewed from above to generate buoyancy. Hereinafter, the rotation direction indicates the rotation direction as viewed from above unless otherwise specified. The prime mover 8 and the prime mover 10 are directly connected to a propeller having a pitch that rotates clockwise to generate buoyancy. As an example, the prime mover is an air-cooled two-cycle gasoline engine, but the prime mover is not limited to this.

  If necessary, the number of blades of the propeller may be two or more. A plurality of landing legs 11 each having a telescopic shock absorbing function as an landing gear are provided in the vicinity of each prime mover in the vicinity of each prime mover. A hammock or swing-shaped seat 2 on which a passenger sits is suspended at or near the center of gravity of the entire aircraft.

  In addition, the location to hang is not limited to one location, but can be suspended at two locations in a swing shape. Furthermore, it can be hung from many hanging points. The control stick 3 is provided so as to be perpendicular to the front of the operator, and is fixed to the component 1. At the lower end of the control stick 3, a T-shaped T-shaped grip 4 is provided so as to be rotatable about the axis of the control stick 3.

  As shown in FIG. 1 and FIG. 2, the basic structures are arranged so as to be orthogonal to each other and have an X-shape. A prime mover is fixed to each X-shaped end. The prime mover 7 and the prime mover 9 are directly connected to a propeller having a pitch that rotates counterclockwise as viewed from above to generate buoyancy.

  Hereinafter, the rotation direction indicates the rotation direction as viewed from above unless otherwise specified. The prime movers 8 and 10 are directly connected to a propeller having a pitch that rotates clockwise to generate buoyancy. If necessary, the number of blades of the propeller may be two or more. One landing leg 11 having a telescopic shock absorbing function as an landing gear is provided on each inner side of each component in the vicinity of the prime mover, in this example, a total of four.

  A hammock or swing-like seat 2 on which a passenger sits is suspended at or near the center of gravity of the entire aircraft. In addition, the place to hang is not limited to one place, and can be hung from two places like a swing, or may be hung from a plurality of places. It is only necessary that the position of the center of gravity of the passenger and the equipment can be moved within the horizontal plane. The control stick 3 is provided so as to be perpendicular to the front of the operator, and is fixed to the component 1. A T-shaped grip 4 is rotatably provided at the lower end of the control stick.

  As shown in FIGS. 3 and 5, the T-shaped grip 4 can be rotated about the axis of the control stick 3, and the horizontal portion of the T-shaped grip 4 is provided with a throttle grip 5 for adjusting the motor output. ing.

  The throttle grip portion 5 is structured to be rotatable around the horizontal axis of the T-shaped grip 4. When the throttle grip portion 5 is rotated counterclockwise as shown in the right side view of FIG. 3, the throttles of all the prime movers are The number of rotations of the opening prime mover increases and the lift generated by the propeller increases. As shown in FIG. 5, the throttles of the prime mover are respectively connected to the throttle A1 to the prime mover A7, the throttle wire B13 to the prime mover B8, the throttle wire C13 to the prime mover C9, and the throttle roll D14 to the prime mover D10.

  Each throttle wire A12, throttle wire B13, throttle wire C14, and throttle wire D15 have a structure in which the throttle of each prime mover can be opened and closed by pulling or loosening the flexible core wire 18, respectively. All throttle wires are composed of a flexible outer tube 19 and a flexible core wire 18 passed through the flexible outer tube 19.

  A throttle valve (not shown) is urged by a spring so as to be always closed. When the flexible core wire 18 is connected to the throttle valve and pulled against the spring energizing the throttle valve, the throttle valve opens and the motor speed increases. On the contrary, the tension of the core flexible core wire 18 is reduced and loosened. The throttle valve, which is energized by the spring, moves in the closing direction, and the rotational speed of the prime mover decreases.

  As shown in FIG. 3, the T-shaped grip 4 includes a T pipe 16, a throttle grip portion 5, and a throttle wire receiver 25. The T pipe 16 includes a throttle wire A12, a throttle wire B13, a throttle wire C14, and a throttle wire. There is a disc-shaped flange to which D15 is attached, and it passes through the flexible core wire 18 of each throttle wire.

  On the right side of the T-pipe 16 is a threaded portion 17 with a right male thread cut. The throttle grip portion 5 is provided with a ball joint portion 24 inside, and a right female screw is provided on the inner peripheral portion, and is fitted with a male screw of the T pipe 16 and a screw portion 17. A flange portion 23 is provided at the lower part of the control stick 3, and a screw that holds the flexible outer tube 19 of all the throttle wires and that is fitted with an adjustment bolt 21 with a hole through which the flexible core wire 18 passes is circumferentially provided. It is placed in a superior position. Each flexible core wire 18 that has passed through the adjustment bolt 21 intersects the flexible core wires 18 that have passed through the front and rear adjustment bolts 21, and the holes are arranged on the circumference of the wire mounting flange portion 22 of the T pipe 16. Is going through.

  As each flexible core wire 18 passes through the mounting flange portion, it is guided to the flexible outer tube 19 and guided to the inside of the T-pipe 16, and the flexible outer tube 19 reaches the partition wall portion 28. The flexible core wire 18 passes through individual holes provided in the partition wall portion 28, and its end portion is fixed to the throttle wire receiver 25.

  Since the flexible core wire can be pulled, loosened, and adjusted by rotating each adjustment bolt 21, adjustment is made before the flight so that the number of rotations of each prime mover becomes the same. When the adjustment bolt 21 is rotated to the right, the tension of the flexible core 18 is loosened and the motor rotation is decelerated. On the other hand, when the adjustment bolt 21 is rotated counterclockwise, the flexible core 18 is tensioned and the motor rotation is increased.

  When the throttle grip portion 5 is rotated, the ball joint portion 24 is moved along the axial center by the action of the screw portion 17. Therefore, the throttle wire receiver 25 is also moved through the ball joint portion 24 to be flexible. The core wire 18 is pulled or loosened simultaneously. For example, when the throttle grip portion 5 is rotated to the right, the ball joint portion 24 is moved to the right side due to the action of the screw and the throttle wire receiver 25 is also moved. For this reason, all the flexible core wires are loosened. Decreases and the propeller thrust decreases, so the aircraft descends. On the contrary, when the throttle grip part 5 is rotated counterclockwise, the ball joint part 24 is moved to the left and the throttle wire receiver 25 is moved to the left, so that all the flexible core wires 18 are stretched and the throttle is opened to increase the engine speed. Buoyancy increases and the aircraft rises.

  When the T-shaped grip 4 is rotated in a horizontal plane, each flexible core wire 18 is wound around the cylindrical outer wall of the sleeve 29 attached to the control stick 3 and is opposite to the flexible core wire 18 whose winding angle is increased. A flexible core wire 18 having a small winding angle is formed, and the flexible core wire 18 having a large winding angle is pulled, and conversely, the flexible core wire 18 having a small winding angle is loosened.

  When the throttle wire rotates the T-shaped grip 4 clockwise, the flexible core wires 18 of the throttle wire A12 and the throttle wire C14 are stretched, and since the flexible core wires cross each other, the throttle wire B13 and the throttle wire D15 Since the flexible core wire is arranged so as to be loosened, the rotational speeds of the prime movers A7 and C9 are increased, and conversely, the rotational speeds of the prime movers B8 and D10 are decreased.

Since the motor A7 and the motor C9 are attached to each other and the propeller rotates counterclockwise, the yawing force for moving the structural body 20 in the clockwise direction increases, and conversely, in the clockwise direction attached to the motor B8 and the motor D10, respectively. The rotating propeller has a reduced number of rotations, so that the yaw force that is applied to the component 1 in the clockwise direction increases. As a result, the aircraft rotates clockwise.

  FIG. 3 shows a drawing of the T-shaped grip 4, and there is a threaded portion 17 on the outer periphery of the right end of the T-pipe 16 in the horizontal direction, and a male thread is cut. A cylindrical throttle grip portion 5 provided with a female screw that can be fitted and rotated with the male screw is provided. A ball joint portion 24 is provided inside the closed surface of the throttle grip portion 5, and a cylindrical throttle wire receiver 25 is provided at the other end portion of the ball joint portion 24. The throttle wire receiver 25 moves along the inside of the T pipe 16 but is guided by a pin (not shown) so as not to rotate.

  As shown in FIG. 4, a launch tube 26 is provided in the center of the structure 1, and a gunpowder 27 used for an in-vehicle airbag or the like and a parachute 20 are injected by the explosive force of this gunpowder. An emergency push button for injecting the parachute 20 is provided at an easy-to-operate position, and in the event of an emergency, pressing the button ignites the explosive 27, explodes the explosive, injects and opens the parachute 20 and opens the aircraft suddenly. To soften and prevent crashing into the ground.

  Like the model drone that is currently flying, it is also possible to fly by controlling the attitude of the aircraft by changing the output of multiple prime movers. As shown in FIG. 6, the member supporting the seat supports the seat and the wing with the free ball support portion 30. At the upper end of this member, the wing 32 is provided with a free ball support 31 and is mounted near the center of lift of the wing 32. Although the mounting structure is not shown, the wing 32 shown by an imaginary line has a fifth prime mover and a propeller 6 for moving at high speed.

  In order to show the mechanism part hidden in the wing, the angle of attack of the wing 32 shown by an imaginary line can be freely changed, and can be varied freely from a horizontal angle of attack to a vertical angle of attack by a mechanism (not shown). When taking off, the plane is made almost vertical, and at the time of horizontal flight, the angle of attack is changed so that the wings 32 generate the maximum lift according to the speed. Since the center of lift of the wing 32 substantially coincides with the center of the aircraft weight in the vertical plane, the member that suspends the seat 2 on which the occupant sits is extended upward, and the center of lift of the wing 32 is set here. The structure is such that it can be rotated to change the angle of attack. During high-speed horizontal movement, the lift of the wings 32 bears part of the mass of the aircraft and the occupant, so the burden on the propeller for generating lift can be reduced and fuel consumption can be suppressed. This enables high-speed and long-distance movement.

  In addition, if the rotation of one prime mover decreases or the rotation stops, the occupant operates the control stick to position the load center at the center of lift of the propellers generating lift. It can be moved to maintain the aircraft posture and avoid sudden descent. When it is determined that the worst recovery cannot be performed, the emergency button is pressed to open the parachute 28 and perform soft landing.

  As shown in FIG. 7, a propeller 34 directly connected to the prime mover 33 is provided, and the thing provided at both ends of the structure 1 is a basic structure 35. The prime movers 33 provided at both ends of the basic structure 35 may rotate in the same rotational direction or in opposite directions. What is necessary is just to combine so that the combination from which a rotation direction differs may mutually become the same number when combining the basic structure 35. FIG.

  As shown in FIG. 8, since the flying object can freely change the combination of the basic structures 35 depending on the load weight or the crew, it is possible to configure any flying object. As a result, a safe, reliable and economical flight can be realized. As with the model drone currently flying at both ends of the structure, it is possible to fly by controlling the attitude of the aircraft by changing the output of multiple prime movers. As shown in FIG. 8, the basic structure 35 can be combined in various shapes, and the shape of the flying object can be arbitrarily changed to match the usage form. As for the rotation direction of the propeller 34, an object that always rotates to the right and an object that rotates in the opposite direction are paired, and the same number is arranged symmetrically with respect to the center of gravity. Alternatively, the right rotating propeller 34 and the left rotating propeller 34 are arranged symmetrically with respect to the center of gravity. The shape illustrated in FIG. 8 does not show the entire arrangement of the basic structure 35, and can be configured in an arbitrary shape other than this drawing.

  By realizing a small flying object composed of any combination of basic structures, it is possible to fly easily and at low cost based on the Aviation Law. As a result, operations conventionally performed by a helicopter or the like can be performed more easily and conveniently. The small projectile does not require a large space for takeoff and landing, and can be used on the rooftop of an existing building or a small takeoff and landing field. Since the mechanism is simple, the manufacturing cost is low and at the same time it can contribute to the improvement of flight reliability. Because it can fly easily even when land traffic is not possible due to congestion, accidents and disasters, it is excellent as a means of transportation for individuals or small groups. In addition, it can be dispatched to the scene in the event of an accident or incident, and is highly useful for collecting information, searching, and rescue.
