Technical Field

[0001] The utility model relates to the technical field of target drone accessories, in particular to a strong stealth backpack type oblique incision target drone air inlet. Background Art

[0002] As modern warfare places increasingly higher demands on the stealth performance of target drones, the stealth performance of the target drone's air intake, as one of the three major forward scattering sources of the aircraft, is of great significance to the overall stealth effect of the aircraft.

[0003] The air intakes of target drones currently in use are mostly located at the bottom of the aircraft or on both sides of the fuselage. The openings are vertical and the airflow path is also straight. The position of the air intake is prone to generating radar signal reflections from the ground. In addition, the radar cross section (RCS) of the target drone is the intensity of the echo generated by the target under radar wave irradiation, and the infrared radiation characteristics of the engine are easily exposed at the air intake position. There is room for further improvement in stealth capability, and it does not have the function of enhancing stealth capability with a back-mounted oblique cut.

[0004] Now, a new type of highly stealthy backpack-type oblique-cut target drone air inlet is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a strong stealth backpack oblique cut target drone air inlet to solve the problem proposed in the above background technology that the backpack oblique cut does not have the function of enhancing the stealth capability.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a highly stealthy backpack-type oblique-cut target drone air inlet, comprising an air inlet inner cavity, an air inlet outer surface being sleeved on one side of the outside of the air inlet inner cavity, an air inlet opening triangular support plate being fixedly connected to one side of the bottom of the air inlet inner cavity, an oblique-cut air inlet opening being obliquely provided on one side of the air inlet inner cavity, the oblique-cut air inlet opening being provided above the target drone, the oblique opening of the oblique-cut air inlet opening being upward, and the entire air inlet adopts a backpack-type configuration.

[0007] Preferably, the bottom of the triangular support plate of the air inlet is fixedly connected with an arc-shaped connecting port, and the top of the arc-shaped connecting port is connected to the bottom of the outer surface of the air inlet.

[0008] Preferably, the outer surface of the air inlet is the main load-bearing structural component installed in the entire air inlet, and the overall shape is integrated with the appearance of the target drone.

[0009] Preferably, the inner cavity of the air inlet duct is a main component of the air inlet duct, and the inner cavity of the inner cavity of the air inlet duct adopts a streamlined design.

[0010] Preferably, the oblique air inlet port and the interior of the air inlet inner cavity are connected, and an engine connection port is provided on the other side of the air inlet inner cavity, and the engine connection port is docked with the target drone engine.

[0011] Preferably, the side of the air inlet outer surface near the beveled air inlet opening is tightly fitted with the outer wall of the air inlet inner cavity, and there is a gap between the side of the air inlet outer surface far from the beveled air inlet opening and the outer wall of the air inlet inner cavity.

[0012] Preferably, vibration sensors are installed at the front and rear ends of the air inlet triangular support plate respectively, the vibration sensors are connected to the target drone's central console signal, and a curved outer cover is provided on the outside of the vibration sensor.

[0013] Compared with the existing technology, the beneficial effects of the present invention are as follows: the strong stealth backpack oblique cut target drone air intake realizes the function of enhancing stealth capability by the backpack oblique cut, realizes the function of enhancing stability by the integrated appearance, and realizes the function of sensing air intake vibration;

[0014] (1) By providing an oblique air inlet, an air inlet cavity and an engine connection port, when in use, the air inlet of the air inlet cavity is an oblique air inlet, which is located on the back of the target aircraft. The back-mounted design and the oblique air inlet can reduce the radar signal reflection generated by the target aircraft at the air inlet position. Combined with the streamlined design of the air inlet cavity, while ensuring the engine intake flow, the radar signal wave entering from the ground direction is scattered or reflected above the oblique air inlet through multiple reflections in the air inlet, thereby reducing the RCS of the target aircraft and providing strong stealth characteristics for the target aircraft. The airflow enters the air inlet cavity along the oblique air inlet, and supplies air to the target aircraft engine through the engine connection port, thereby realizing the function of the back-mounted oblique inlet to enhance the stealth capability.

[0015] (2) By providing the air inlet triangular support plate, the air inlet outer surface and the arc-shaped connecting port, when in use, the air inlet triangular support plate and the air inlet outer surface are integrated with the target drone's outer shape, and the arc-shaped connecting port is docked with the back of the target drone. The streamlined design ensures the aerodynamic characteristics of the target drone's overall aerodynamic shape, improves the target drone's aerodynamic performance and stability, and realizes the function of enhancing stability through the integrated shape;

[0016] (3) By providing a curved outer cover and a vibration sensor, when the target drone is in flight, air flows in at high speed from the oblique air inlet. When the curved connection port is not tightly connected to the triangular support plate 2 of the air inlet and becomes loose, the entire cavity of the air inlet will vibrate. The vibration sensor can quickly capture the vibration signal and feed it back to the target drone console, facilitating timely perception and maintenance. The curved outer cover can protect the vibration sensor to prevent misjudgment caused by wind, thereby realizing the function of sensing the vibration of the air inlet.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , a strong stealth backpack oblique cut target drone air inlet, comprising an air inlet inner cavity 4, and an oblique cut air inlet opening 1 is obliquely provided on one side of the air inlet inner cavity 4;

[0024] The oblique air inlet 1 is arranged above the target drone, with the oblique opening of the oblique air inlet 1 facing upward. The entire air inlet adopts a backpack configuration. The air inlet inner cavity 4 is the main component of the air inlet. The inner cavity of the air inlet inner cavity 4 adopts a streamlined design. The oblique air inlet 1 and the interior of the air inlet inner cavity 4 are connected. The other side of the air inlet inner cavity 4 is provided with an engine connection port 6, which is connected to the target drone engine. The backpack oblique cut structure can enhance the stealth capability of the target drone.

[0025] Specific as Figure 1 and Figure 2As shown, the oblique air inlet 1 is located on the back of the target drone. The back-mounted design and the oblique air inlet 1 can reduce the radar signal reflection generated by the target drone at the air inlet position. Combined with the streamlined design of the air inlet cavity 4, while ensuring the engine intake flow, the radar signal waves entering from the ground direction are reflected and scattered multiple times through the air inlet cavity 4 or reflected above the oblique air inlet 1, thereby reducing the RCS of the target drone and providing the target drone with strong stealth characteristics. The airflow enters the air inlet cavity 4 along the oblique air inlet 1 and supplies air to the target drone engine through the engine connection port 6.

[0026] One side of the outside of the air inlet cavity 4 is sleeved with the air inlet outer surface 3, one side of the bottom of the air inlet cavity 4 is fixedly connected with the air inlet triangular support plate 2, the bottom of the air inlet triangular support plate 2 is connected with an arc-shaped connecting port 5, the top of the arc-shaped connecting port 5 is connected to the bottom of the air inlet outer surface 3, the air inlet outer surface 3 is the main load-bearing structural component installed in the entire air inlet, and the overall shape is integrated with the target drone shape. The side of the air inlet outer surface 3 close to the beveled air inlet port 1 is tightly fitted with the outer wall of the air inlet cavity 4, and there is a gap between the side of the air inlet outer surface 3 away from the beveled air inlet port 1 and the outer wall of the air inlet cavity 4, so that the installation is stable while ensuring aerodynamic performance and stability;

[0027] Specific as Figure 1 and Figure 4 As shown, the triangular support plate 2 of the air inlet and the outer surface 3 of the air inlet are integrated with the appearance of the target drone, the arc-shaped connecting port 5 is docked with the back of the target drone, and the streamlined design of the inner cavity 4 of the air inlet can improve the aerodynamic performance and stability of the target drone.

[0028] The front and rear ends of the triangular support plate 2 of the air inlet are respectively installed with vibration sensors 8, which are connected to the target drone's central console signal. The outer surface of the vibration sensor 8 is provided with a curved outer cover 7. Through the vibration sensor 8, the target drone's central console can timely sense when the air inlet shakes.

[0029] Specific as Figure 1 and Figure 4 As shown, the vibration sensor 8 can quickly capture the vibration signal and feed it back to the target drone console, making it convenient for the ground to perceive and repair it in time. The curved outer cover 7 can protect the vibration sensor 8 to prevent misjudgment caused by wind influence.

[0030] Working Principle: When the present invention is in use, first, the air inlet of the air inlet cavity 4 is a beveled air inlet 1, which is located on the back of the target drone. The piggyback design and the beveled air inlet 1 can reduce the radar signal reflection generated by the target drone at the air inlet position. Combined with the streamlined design of the air inlet cavity 4, while ensuring the engine intake flow, the radar signal waves entering from the ground direction are reflected and scattered multiple times through the air inlet cavity 4 or reflected above the beveled air inlet 1, thereby reducing the RCS of the target drone and providing it with strong stealth characteristics. The airflow enters the air inlet cavity 4 along the beveled air inlet 1 and supplies air to the target drone engine through the engine connection port 6. The air inlet triangular support plate 2 and the air inlet outer surface 3 are designed to be integrated with the target drone's appearance. The arc-shaped connection port 5 is connected to the back of the target drone. The streamlined design of the air inlet cavity 4 ensures the aerodynamic characteristics of the target drone's overall aerodynamic shape, improving the target drone's aerodynamic performance and stability. When the target drone is in flight, air flows in at high speed from the beveled air inlet 1. When the arc-shaped connecting port 5 is not tightly connected to the triangular support plate 2 of the air inlet and becomes loose, the air inlet outer surface 3 and the air inlet inner cavity 4 may vibrate as a whole. Then, the vibration sensor 8 can quickly capture the vibration signal and feed it back to the target drone's central console, facilitating timely perception and maintenance. The arc-shaped outer cover 7 can protect the vibration sensor 8 to prevent misjudgment caused by wind influence.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
