[0022] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0023] Embodiment 1:

[0024] This embodiment provides a powered flying wing capable of vertical take-off and landing, such as Figure 1-Figure 3 As shown, it includes a propeller assembly 3, a traction arm 4, a support frame 1, a left flying wing 21 and a right flying wing 22. The left flying wing 21 and the right flying wing 22 are symmetrically arranged on the left and right sides of the support frame 1 and are rotatably connected to the support frame 1 respectively, the propeller assembly 3 is connected to the top end of the traction arm 4, and the bottom end of the traction arm 4 is rotatably connected to the top end of the support frame 1. When the powered wind-driven wing takes off and lands vertically, the propeller assembly 3 is rotated to a horizontal state through the traction arm 4, and when the powered wind-driven wing flies horizontally, the propeller assembly 3 is rotated to an inclined state through the traction arm 4.

[0025] During takeoff and landing of the powered flying wing of this embodiment, the propeller assembly 3 is rotated to a horizontal state through the traction arm 4, and the angle between the left flying wing 21 and the right flying wing 22 and the ground is adjusted to nearly 90 degrees. At this time, the propeller assembly 3 provides the lift required for flight. By adjusting the rotation speed of the propeller assembly 3, the corresponding lift is obtained to achieve the purpose of lifting and lowering the powered flying wing, thereby realizing vertical take-off and landing. When the powered flying wing is flying horizontally, the propeller assembly 3 is rotated to an inclined state through the traction arm 4, and the angle between the left flying wing 21 and the right flying wing 22 and the ground is small. At this time, the wing surface of the flying wing provides the main lift required for the aircraft.

[0026] The powered flying wing of this embodiment eliminates the bulky cockpit of the traditional powered flying wing and the driving propeller located behind the cockpit, and adds a propeller assembly 3 above the flying wing. The vertical take-off and landing of the powered flying wing are achieved by adjusting the inclination angles of the propeller assembly 3 and the left flying wing 21 and the right flying wing 22 during take-off and landing, without the aid of a runway, thereby solving the technical problem that the existing powered flying wing cannot take off and land vertically.

[0027] Preferably, if Figure 2 and Figure 3 As shown, the traction arm 4 is connected to the support frame 1 through the front and rear tilting steering gear 5, and the front and rear tilting steering gear 5 drives the traction arm 4 to rotate forward and backward relative to the support frame 1 through the connecting rod assembly 9 to adjust the tilt angle of the propeller assembly 3.

[0028] Specifically, the connecting rod assembly 9 is located at the front side of the traction arm 4, and the connecting rod assembly 9 includes a first connecting rod 91 and a second connecting rod 92. One end of the first connecting rod 91 is hinged to the front side of the traction arm 4, and the other end is hinged to the upper end of the second connecting rod 92. The lower end of the second connecting rod 92 is connected to the output shaft of the front and rear tilting servo 5. The traction arm 4 is rotatably connected to the top of the supporting frame 1 through a rotating shaft. The front and rear tilting servo 5 is installed on the top of the supporting frame 1 and is located on the lower side of the rotating shaft. The rotation of the output shaft of the front and rear tilting servo 5 can pull the second connecting rod 92 and adjust the angle between the first connecting rod 91 and the second connecting rod 92, thereby driving the traction arm 4 to rotate forward and backward relative to the supporting frame 1.

[0029] like Figure 2 and Figure 3As shown, when the powered flying wing is adjusted from a vertical take-off state to a level flight state, the front and rear tilting servos 5 drive the angle between the first connecting rod 91 and the second connecting rod 92 to decrease, and the traction arm 4 rotates forward relative to the support frame 1, so that the propeller assembly 3 is gradually adjusted from a horizontal state to a tilted state. When the powered flying wing is adjusted from a level flight state to a vertical landing state, the front and rear tilting servos 5 drive the angle between the first connecting rod 91 and the second connecting rod 92 to increase, and the traction arm 4 rotates backward relative to the support frame 1, so that the propeller assembly 3 is gradually adjusted from a tilted state to a horizontal state.

[0030] Preferably, if Figure 2 and Figure 3 As shown, the left flying wing 21 and the right flying wing 22 are connected to the support frame 1 through the wing surface tilting steering gear 6, respectively, and the wing surface tilting steering gear 6 adjusts the angle between the left flying wing 21 or the right flying wing 22 and the horizontal plane through the connecting rod assembly 9, so that the left flying wing 21 or the right flying wing 22 can be adjusted independently. The left flying wing 21 and the right flying wing 22 are connected to the support frame 1 through a rotating shaft, respectively, and the rotating shaft is arranged along the left and right directions of the support frame 1, so that the left flying wing 21 and the right flying wing 22 can rotate forward and backward to adjust the angle between the left flying wing 21 or the right flying wing 22 and the horizontal plane.

[0031] Specifically, the connecting rod assembly 9 includes a first connecting rod 91 and a second connecting rod 92. One end of the first connecting rod 91 is hinged to the left flying wing 21 or the right flying wing 22, and the other end is hinged to the upper end of the second connecting rod 92. The lower end of the second connecting rod 92 is connected to the output shaft of the wing surface tilt servo 6. The wing surface tilt servo 6 is installed on the supporting frame 1 on the lower side of the rotating shaft of the left flying wing 21 or the right flying wing 22. The rotation of the output shaft of the wing surface tilt servo 6 can pull the second connecting rod 92 and adjust the angle between the first connecting rod 91 and the second connecting rod 92, thereby driving the left flying wing 21 or the right flying wing 22 to rotate forward and backward relative to the supporting frame 1.

[0032] like Figure 2 and Figure 3 As shown, when the powered flying wing is adjusted from the vertical take-off state to the level flight state, the wing surface tilting servo 6 drives the angle between the first connecting rod 91 and the second connecting rod 92 to increase, and the left flying wing 21 or the right flying wing 22 rotates clockwise relative to the supporting frame 1, so that the left flying wing 21 or the right flying wing 22 is gradually adjusted from a nearly vertical state to a nearly horizontal state. When the powered flying wing is adjusted from the level flight state to the vertical landing state, the wing surface tilting servo 6 drives the angle between the first connecting rod 91 and the second connecting rod 92 to decrease, and the left flying wing 21 or the right flying wing 22 rotates counterclockwise relative to the supporting frame 1, so that the left flying wing 21 or the right flying wing 22 is gradually adjusted from a nearly horizontal state to a nearly vertical state.

[0033] Preferably, if Figure 2As shown, the propeller assembly 3 includes a first propeller 31, a second propeller 32 and a left-right tilting steering gear 33. The first propeller 31 and the second propeller 32 are coaxially connected through a connecting shaft 34 and the first propeller 31 and the second propeller 32 are arranged in parallel, and the output end of the left-right tilting steering gear 33 is connected to the connecting shaft 34 to drive the propeller assembly to tilt left and right. The left-right tilting steering gear 33 can adjust the left-right tilt of the first propeller 31 and the second propeller 32 to flexibly adjust the flight attitude of the powered flying wing.

[0034] Preferably, the output shaft of the left-right tilt steering gear 33 is connected with a sleeve 35, and the sleeve 35 is rotatably mounted on the top of the traction arm 4. The first propeller 31 and the second propeller 32 are connected to the sleeve 35 at the upper and lower sides of the sleeve 35 through the connecting shaft 34. The left-right tilt steering gear 33 drives the sleeve 35 to rotate at the top of the traction arm 4, thereby mobilizing the first propeller 31 and the second propeller 32 to tilt left or right at the same time.

[0035] Preferably, if Figure 2 As shown, the traction arm 4 includes a lower arm section 41, a connecting section 42 and an upper arm section 43. The lower arm section 41 and the upper arm section 43 are respectively connected to the two ends of the connecting section 42 and the lower arm section 41 and the upper arm section 43 are arranged at an acute angle, so that the traction arm 4 is a V-shaped structure with good support stability, and the first propeller 31 and the second propeller 32 are respectively connected to the upper and lower sides of the upper arm section 43, so as to effectively support the propeller assembly 3. The lower arm section 41 is rotatably connected to the top of the support frame 1. When the powered flying wing takes off and lands vertically, the propeller assembly 3 is connected to the top of the upper arm section 43 and is arranged directly above the support frame 1. Through the rotation of the first propeller 31 and the second propeller 32, the powered flying wing is provided with vertical lift.

[0036] Preferably, the powered flying wing capable of vertical take-off and landing of this embodiment further comprises a seat 8, a support frame 1 comprises a rear strut 12 and two front struts 11, the top ends of the rear strut 12 and the two front struts 11 are connected at one point and the bottom ends thereof are connected by a connecting cross bar 13 to form a triangular bracket, and the seat 8 is arranged on the inner side of the triangular bracket and connected between the two front struts 11. The support frame 1 formed by the rear strut 12 and the two front struts 11 is a triangular bracket, which makes it have better stability. The seat 8 is arranged on the inner side of the triangular bracket, making full use of the space inside the support frame 1, and has better safety and connection stability.

[0037] Preferably, the powered flying wing capable of vertical take-off and landing of this embodiment further comprises a battery pack 7, which is mounted on the supporting frame 1, and is electrically connected to the front and rear tilting servo 5, the wing surface tilting servo 6, and the left and right tilting servo 33. The battery pack 7 provides power for the front and rear tilting servo 5, the wing surface tilting servo 6, and the left and right tilting servo 33, and the front and rear tilting servo 5, the wing surface tilting servo 6, and the left and right tilting servo 33 are connected to a controller, which is arranged on the front side of the seat, so that the driver can control the flight state of the powered flying wing while sitting on the seat.

[0038] When the powered flying wing of this embodiment takes off, its overall posture is perpendicular to the ground. At this time, the battery pack 7 provides electrical energy to drive the propeller assembly 3 located at the highest point of the powered flying wing to rotate. As the rotation speed increases, the upward lift generated by the propeller is also increasing. When the propeller lift is greater than the power flying wing's own gravity, the powered flying wing begins to rise due to the upward pull of the propeller and completes the take-off action. At this time, the propeller assembly 3 provides all the lift required by the flying wing.

[0039] After the powered flight wing completes the take-off action, the traction arm 4 can be manipulated to rotate forward by the front and rear tilting servos 5 and drive the propeller assembly 3 to tilt forward, gradually pulling the powered flight wing to a level flight state to complete the forward flight action. At this time, the wing surface bears most of the lift required for flight. The adjustment of the flight attitude is coordinated by the front and rear tilting servos 5, the left and right tilting servos 33 and the two wing surface tilting servos 6.

[0040] When the powered flying wing is landing, the propeller assembly can be tilted upward by tilting the servo 5 forward and backward to gradually adjust the powered flying wing to an upright state, and then the propeller speed is slowly reduced. When the lift generated by the propeller is less than the weight of the powered flying wing itself, the powered flying wing begins to descend and completes the landing action.

[0041] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
