Description

Technical Field

[0001] The utility model relates to the field of aviation technology, and particularly relates to a three-axis flying motorcycle. Background Art

[0002] However, current general urban aircraft have two seats, four seats and six seats, mainly compound wings and tilt rotors, and there are also multi-rotor urban aircraft. Compound wings and tilt rotor aircraft generally have a relatively long wingspan, resulting in a large volume of the aircraft and a large usage space, which is inconvenient for personal travel and home use. And pure multi-rotors do not have advantages in terms of speed and endurance.

[0003] Therefore, we have considered whether there is a small-volume personal flying vehicle / aircraft that can not only meet the vertical takeoff and landing function and does not require too much takeoff space during use, but also has good safety performance, as well as the characteristics of long endurance and long range.

Detailed implementation manners

[0030] To make the above content, objectives and beneficial effects of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0031] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] As Figure 1-6 shown, the present utility model provides a three-axis flying motorcycle, including a fuselage 1, a wing 3, a front rotor duct 4, a front rotor duct power device 5, a rear rotor duct 7, a rear rotor duct power device 8, a rear landing gear and a retractable front landing gear 11.

[0033] Among them, as Figure 1As shown, the wing 3 is symmetrically mounted and fixed to the lower front end of the fuselage 1 through the wing support 2. The front rotor duct 4 is symmetrically mounted and fixed to both sides of the front end of the fuselage 1 through the duct mounting bracket 6, and the front rotor duct power device 5 is arranged and installed in the front rotor duct 4. The rear rotor duct 7 is installed and fixed to the tail end of the fuselage 1, and the rear rotor duct power device 8 is arranged and installed in the rear rotor duct 7. The rear landing gear is symmetrically mounted and fixed to the lower middle part of the fuselage 1, and the retractable front landing gear 11 is arranged and installed at the lower front end of the fuselage 1 and behind the wing support 2.

[0034] Furthermore, the fuselage 1 adopts a streamlined design, but is not limited to a streamlined fuselage. The upper part of the fuselage 1 is regularly provided with a cockpit cover 101 that can be flipped open, and seats and a control module for the flying motorcycle are regularly arranged and installed in the cockpit inside the cockpit cover 101.

[0035] Furthermore, the wing support 2 adopts a symmetrical airfoil, and the wing support 2 connects the lower front end of the fuselage 1 and the middle part of the wing 3. The wing support 2 can enhance the installation structure of the front rotor duct 4 while also playing the role of a partial vertical fin to enhance the course stability.

[0036] Furthermore, the wing 3 adopts a low-speed high-lift airfoil and is symmetrically arranged on both sides of the front end of the fuselage 1. The left and right tip parts of the wing 3 are respectively connected to the left and right front rotor ducts 4.

[0037] Furthermore, as Figure 1 shown, the front rotor ducts 4 located on both sides of the fuselage are arranged and installed on both sides of the front end of the fuselage 1 through the left and right duct mounting brackets 6. The rear ends of the left and right duct mounting brackets 6 are respectively connected to both sides of the front end of the fuselage, and their front ends are respectively connected to the left and right front rotor ducts. The fuselage 1, the wing support 2, the wing 3, the left and right duct mounting brackets 6, and the left and right front rotor ducts 4 together form a box structure, thereby greatly enhancing the structural strength. As Figure 3 shown, the left and right duct mounting brackets 6 are inclined forward to form a stable triangular structure with the wing 3,

[0038] Furthermore, the front rotor duct power device 5 includes two sets of motors and propellers that are coaxially and rotationally installed in the same direction.

[0039] Furthermore, the rotation directions of the front rotor duct power devices 5 on both sides are opposite to cancel out the torque generated by the propellers. In one embodiment, the right front rotor duct power device rotates clockwise, and the left front rotor duct power device rotates counterclockwise.

[0040] Furthermore, the rear rotor duct power device 8 includes two sets of motors and propellers that are coaxially and rotationally installed in the opposite direction.

[0041] Furthermore, the rear landing gear includes a rear landing gear fairing bracket 9 and rear landing gear wheels 10. Among them, the rear landing gear fairing bracket 9 adopts an airfoil design, which can reduce drag and increase a part of lift while connecting the rear landing gear wheels 10.

[0042] Furthermore, as Figure 2 shown, the rear landing gear wheels 10 are wrapped by a fairing 12, thereby further reducing drag.

[0043] Furthermore, as Figure 1 and Figure 6 shown, the retractable front landing gear 11 includes a retractable bracket assembly and wheels. When the flying motorcycle is flying forward, the front landing gear is retracted into the fuselage 1 through the retractable bracket assembly, thereby reducing flight resistance.

[0044] Furthermore, as Figure 1 and Figure 2 shown, the rear landing gear and the retractable front landing gear form a three-point landing gear.

[0045] As Figure 4 shown, the side view of the three-axis flying motorcycle of the present utility model in the grounded state is shown. The front rotor duct 4 and the rear rotor duct 7 are both arranged and installed with a forward inclination angle, and the inclination angles are kept consistent. In this way, the power of the front rotor duct power device 5 and the rear rotor duct power device 9 can be divided into two, respectively forming a forward thrust and an upward lift.

[0046] As Figure 5 shown, when the front rotor duct 4 and the rear rotor duct 7 are adjusted to the horizontal state, the front rotor duct power device and the rear rotor duct power device provide an upward lift, thereby realizing the vertical takeoff and landing of the flying motorcycle.

[0047] As Figure 6 shown, when the front rotor duct and the rear rotor duct are adjusted to the forward inclination state, the front rotor duct power device and the rear rotor duct power device provide a forward thrust and an upward lift, thereby realizing the forward flight of the flying motorcycle. At the same time, the retractable front landing gear 11 is driven by a power device and retracted into the interior of the fuselage 1.

[0048] The above specific embodiments further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
