Description

Technical Field

[0001] The present invention relates to the technical field of aircraft, and in particular to a flying device and a flying car with a tethered ducted fan. Background Art

[0002] In many low-altitude economic application scenarios, the integrated flying cars used in modern aviation aircraft have many limitations in the application scenarios. The traditional fixed-wing flying cars do not operate well on the road. The existence of fixed wings greatly increases the size of the vehicle body compared to ordinary cars, and the flight start process requires a certain amount of acceleration space; in addition, non-fixed-wing flying cars mostly use open propeller structures. The rotor drone structure makes the rotor parts of the flying car occupy a large space, and the stability cannot be guaranteed when running on land. There are also widespread problems of insufficient torque, inter-propeller effect and huge noise. When the aircraft is in working state, there are problems of insufficient power, unstable operation state and noise at high speed. Especially in the current popular low-altitude economic application field, due to the complex and crowded urban three-dimensional space, the aircraft must take into account the convenience of land and air operation. Combined with travel needs, the aircraft must have strong power, stable operation and low noise characteristics.

[0003] As a type of car, the flying car's ground operating performance is a key factor to consider. Traditional flying cars generally use a mature fixed-wing structure or an open propeller blade structure, which has an adverse effect on the ground operating performance of the flying car. Therefore, the ground and air operation of flying cars and their combination methods need to be rethought. Summary of the invention

[0004] The purpose of the present invention is to solve the flight limitation problem of traditional flying cars in urban space layout and the widespread land operation limitation problem of flying cars, and to provide a split flying car with a tethered ducted fan.

[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The specific embodiments of the present invention are described in detail below.

[0025] like Figures 1 to 6 As shown, the present invention provides a specific embodiment of a flying device with a tethered ducted fan, comprising a fuselage 1 and a power unit 2 disposed on the fuselage 1; The power unit 2 includes two duct assemblies 20 arranged side by side on the fuselage 1, each duct assembly 20 includes two duct shells 201 arranged up and down, and there is a gap between the two duct shells 201; the upper part of the duct of the upper duct shell 201 is an air inlet, and the lower part of the duct of the lower duct shell 201 is an air outlet; a stator shaft 202 is provided through the middle of the two duct shells 201, and two groups of acceleration blades 203 are fixedly provided between each duct shell 201 and the stator shaft 202, and each group of acceleration blades 203 is radially evenly distributed with the stator shaft 202 as the center; the bending directions of the acceleration blades 203 of the two duct assemblies 20 are different, and the bending directions of the acceleration blades 203 of the two duct assemblies 20 are adapted to the flow direction of the airflow in the two duct shells 201; A group of anti-twist blades 204 is arranged between two adjacent groups of acceleration blades 203. Each group of anti-twist blades 204 is evenly distributed radially with the stator shaft 202 as the center. Each group of anti-twist blades 204 is rotatably arranged on the stator shaft 202, and the anti-twist blades 204 located in the middle group are located between the two duct shells 201 arranged upper and lower; the inclination direction of the anti-twist blades 204 in the same duct component 20 is adapted to the acceleration blades 203.

[0026] like Figure 3 As shown, taking one of the duct components 20 as an example, the acceleration blade 203 marked by part A in the figure is gradually bent downward from right to left, and the concave surface of the acceleration blade 203 faces downward, and the bending direction of other acceleration blades 203 is similar; similarly, the acceleration blades 203 in the same duct component 20 have the same bending direction. Another duct component 20 (not shown in the figure) has its acceleration blade 203 gradually bent downward from left to right, and the concave surface of the acceleration blade 203 faces downward.

[0027] Specifically, the stator shaft 202, the accelerating blades 203 and the duct housing 201 in this embodiment rotate synchronously. In this embodiment, the accelerating blades 203 in the two duct components 20 rotate in opposite directions and can offset each other's rotation torque. In this embodiment, the stator shaft 202 can be controlled by a motor, or the stator system of the duct fan device (CN 112583223 B) integrated with the permanent magnet synchronous disc-type flat wire motor can be used to achieve rotation. In this embodiment, the rotation control of the stator shaft 202 can also be achieved by other methods or principles. In this embodiment, when the stator system of the duct fan device integrated with the permanent magnet synchronous disc-type flat wire motor is used, the free end of the anti-twist blade 204 located in the middle of the duct component 20 is used to fix the stator. This rotation principle is not the core of the present invention, so it will not be repeated here.

[0028] The reverse twist blades 204 located at the upper and lower parts of the duct assembly 20 are as shown in FIG. Figure 6As shown in the upper middle figure, the reverse twist blade 204 located in the middle of the duct assembly 20 is as shown in FIG. Figure 6 Taking the anti-twist blade 204 marked in part B of the figure as an example, the anti-twist blade 204 located at the upper and lower parts of the duct assembly 20 is inclined in a direction similar to that of the acceleration blade 203, and is arranged gradually downward from right to left.

[0029] Taking the reverse twist blade 204 marked in part C in the figure as an example, the free end of the reverse twist blade 204 located in the middle part of the duct assembly 20 is twisted clockwise to the horizontal direction.

[0030] Specifically, the reverse twist blade 204 in this embodiment is rotatably matched with the stator shaft 202 , and there is a gap between the end of the reverse twist blade 204 and the duct casing 201 .

[0031] The duct assembly 20 of this embodiment has four stages of accelerating blades 203 therein. After the airflow is accelerated four times, a high-speed airflow is generated at the duct outlet, providing a lifting force and driving the entire flying device to rise.

[0032] Specifically, Figure 1 and 2 As shown, it also includes four auxiliary fans 205 arranged around the fuselage 1. The four auxiliary fans 205 are symmetrically installed at the four corner edges of the flying device at the center of the overall structure. The speed and rotation direction of the four auxiliary fans can be controlled separately to provide the overall structure with horizontal steering power, flat power, and anti-torque of the overall structure.

[0033] like Figure 5 As shown, the duct housing 201 includes an inner shell 211 located inside and in a cylindrical ring shape and an outer shell 212 located outside and in a circular arc ring shape, and the upper and lower edges of the outer shell 212 are respectively connected to the upper and lower edges of the inner shell 211. Further, the duct housing 201 in this embodiment is divided into two parts, which can be spliced ​​together.

[0034] like Figure 7 and 8 As shown, a split flying car includes a car body 3 and the flying device with a tethered ducted fan. The fuselage 1 of the flying device with a tethered ducted fan is located on the top of the car body 3, and at least two tethered cables 301 are arranged between the fuselage 1 and the car body 3, and the tethered cables 301 are wound inside the car body 3.

[0035] There are three operating modes for the split flying car: land mode, reconnaissance mode, and flight mode. When the split flying car is in land mode, the main operating scenario is land. The flying device does not participate in the movement of the car body. The flying device is fixed on the top of the car and has no effect on its land operation performance. In reconnaissance mode, the flying device is suspended in the air, acting as a tethered aerial reconnaissance platform. The car body is on the ground, and the flying device relies on the car body for energy. In flight mode, the flying device rises vertically, drags the car body into the air through the tethered cable, and drives the car body to fly.

[0036] The above is only a specific implementation of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
