Abstract
Description
Technical Field
[0001] This utility model relates to an airbag, specifically an airbag with wingspan, and belongs to the field of aircraft technology. Background Technology
[0002] Aerostats, as flying devices capable of suspending themselves in the atmosphere, are widely used in meteorological observation, communication relay, advertising display, border monitoring, and other fields. They primarily achieve their aerostating effect by filling them with helium or hydrogen. Both helium and hydrogen have a lower density than air, thus providing the aerostat with upward buoyancy, allowing it to remain suspended in the air.
[0003] However, this method of levitation has significant limitations. This type of aerostat relies on helium and hydrogen, gases with densities less than air, to provide upward buoyancy. During long-term use, leaks in the airbags are inevitable. Once leaked, the buoyancy gradually weakens, making it unable to maintain the intended altitude, ultimately requiring reentry and re-inflation. This process is not only time-consuming and labor-intensive but can also lead to interruptions during critical missions, affecting normal operation. Furthermore, frequent inflation and recovery operations increase maintenance costs and shorten the aerostat's lifespan.
[0004] Therefore, the existing air-suspension method of inflating and suspending air makes it difficult to achieve a stable suspension effect over a long period of time, which limits its application in tasks that require long-term continuous operation, such as long-term weather monitoring, continuous communication coverage, and long-term border surveillance.

[0025] Beneficial effects:
[0026] (1) The winged airbag of this utility model has an aerodynamic shape similar to a "bird" and possesses the characteristic of being able to stay airborne by wind and hot air currents. This type of winged airbag can achieve the purpose of staying airborne by utilizing its aerodynamic shape, rather than relying on the buoyancy provided by filling it with helium or hydrogen, which are lighter than air. It can stay airborne for a long time by relying only on wind power, enabling it to operate in the air for a long time. Therefore, the winged airbag can be filled with helium or hydrogen, which are lighter than air, or it can be filled with air, as long as it can maintain its shape.
[0027] (2) The winged airbag of this invention is equipped with an inflation / deflation unit to inflate and deflate the winged airbag, maintaining the internal air pressure within a reasonable range. This allows for adjustment of the internal pressure of the winged airbag according to the external air pressure environment (which varies at different altitudes during use), and also enables direct inflation of the winged airbag to maintain its aerodynamic shape in case of leakage. Therefore, during in-flight use, if the winged airbag leaks, air can be directly added using the inflation unit to maintain its shape, eliminating the need for re-inflation upon landing.
[0028] (3) In the winged airbag of this utility model, air channels are provided on the right wing and the left wing of the airbag to guide airflow and thus ensure the stability of the winged airbag in the air.
[0029] (4) In the winged airbag of this utility model, the tail of the left wing air passage and the right wing air passage of the airbag are both extended with tail wing airbags. The tail wing airbags can further enhance the stability of the attitude control of the winged airbag.
[0030] (5) In the winged airbag of this utility model, the tail wing airbag is provided with an air duct ring. By tightening or loosening the air duct ring, the airflow flowing through the tail wing airbag can be changed, thereby controlling the left and right turning of the lower winged airbag.
[0031] (6) In the winged airbag of this utility model, pitch control of the winged airbag can be achieved by setting front and rear pitch adjustment ropes. The structure is simple and easy to operate. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0037] Example 1:
[0038] This embodiment provides a winged airbag that can achieve the purpose of hovering by utilizing its aerodynamic shape. Thus, it can stay in the air for a long time by using only wind power, thereby solving the problem that traditional inflatable hovering methods are difficult to achieve long-term stable hovering effect.
[0039] like Figure 1 As shown, the winged airbag has a central airbag body 101, a left airbag wing 103 located to the left of the airbag body 101, and a right airbag wing 104 located to the right of the airbag body 101; wherein the airbag body 101 is the main load-bearing structure of the winged airbag; the left airbag wing 103 and the right airbag wing 104 are integrated with the airbag body 101 and are used to enhance the aerodynamic lift of the winged airbag.
[0040] Therefore, this winged gasbag has an aerodynamic shape similar to a bird, possessing the ability to hover using wind and thermal currents. In this design, the winged gasbag achieves its hovering purpose through its aerodynamic shape, rather than relying on the buoyancy provided by filling it with helium or hydrogen, which are lighter than air. It can hover for extended periods using only wind power, enabling it to operate in the air for long periods. Therefore, this winged gasbag can be filled with either helium or hydrogen, which are lighter than air, or with air, as long as it maintains its shape. As an example, initially filling the winged gasbag with helium or hydrogen, which are lighter than air, facilitates lift during takeoff.
[0041] The winged airbag is equipped with an inflation / deflation unit for inflating and deflating the airbag, maintaining the internal air pressure within a set range, and preserving its aerodynamic shape. As one example, the airbag body 101, left wing 103, and right wing 104 can be interconnected, requiring only one inflation unit. Alternatively, they can be independent structures, each with its own inflation unit. In this design, the gas inside the winged airbag is used to maintain its shape. Therefore, during airborne use, if leakage occurs, air can be directly added using the inflation / deflation unit. Even if initially filled with helium or hydrogen (lighter than air), leakage during use can be addressed by adding air using the inflation / deflation unit to maintain its shape.
[0042] As an example, the inflation / deflation unit is an automatic inflation unit, including an air pump installed inside the winged airbag, a pressure sensor installed inside the winged airbag for real-time monitoring of its internal pressure, and inflation / deflation valves (which can be independent inflation and deflation valves) installed on the winged airbag. Based on the internal air pressure monitored by the pressure sensor, the inflation / deflation valves are controlled to open or close, thereby achieving inflation / deflation. During the use of the winged airbag, the external air pressure environment varies at different altitudes; the inflation / deflation unit enables automatic adjustment of the internal pressure of the winged airbag. It can be understood that the inflation / deflation valves are electrically operated valves. A control unit electrically connected to the pressure sensor and inflation / deflation valves can be installed inside the payload compartment 109 of the winged airbag. The control unit controls the closing and opening of the inflation / deflation valves based on the monitoring values of the pressure sensor. This inflation control method is a conventional technical means.
[0043] As an example, the airbag body 101 has an airbag duct 102 at its center, which axially extends through the airbag body 101 to form a stable airflow.
[0044] Based on this, as an example, a wind turbine generator is installed in the airbag duct 102 to achieve in-flight power generation. When the wind turbine generator is installed, the winged airbag can achieve in-flight self-generation, maintaining the power supply self-sufficiency of the in-flight load, and excess power can be transmitted back to the ground for use via cables.
[0045] As an example, a flexible solar panel 112 is provided on the upper surface of the winged airbag (such as the upper surface of the left wing 103 and the right wing 104 of the airbag); the flexible solar panel 112 is bonded to the upper surface of the winged airbag to provide solar power.
[0046] As another example, a propeller power assembly is installed at the tail of the airbag duct 102 for aerial maneuvering of the airbag (therefore, the airbag can be used by being tethered to the ground via a tether cable, or it can be used independently without being tethered to the ground, enabling it to function as an air transport vehicle). Furthermore, a mid-section mounting belt is pre-installed in the middle of the airbag duct 102, and a rear-section mounting belt is pre-installed at the tail of the airbag duct 102; thus, the wind turbine generator and propeller power assembly can be installed according to actual usage requirements.
[0047] As an example, the lower part of the airbag body 101 is provided with a load chamber 109, which can be used to install wind and solar power generation distribution equipment, load equipment, and energy storage equipment, etc.
[0048] As an example, the winged airbag is made using a heat-sealing process (the material has relatively high strength and high wind resistance).
[0049] As an example, a reinforcing band 108 is provided on the winged airbag to enhance its structural strength. The reinforcing band 108 can be provided on the outer and / or inner surface of the winged airbag, and can be one or more bands. Figure 2 As shown, reinforcing bands 108 are provided on the outer surfaces of the airbag body 101, the left wing 103, and the right wing 104 along the transverse (left-right direction).
[0050] As an example, when the winged airbag is used for tethering, the winged airbag is connected to the ground via a tether cable. A tether plug is provided on the winged airbag for connecting the tether cable; the tether cable may be a tensile-resistant fiber optic cable used to transmit electrical energy and communication signals; the tether cable is connected to a ground-based deployment and retrieval device for deploying, retrieving, and retaining the winged airbag.
[0051] Example 2:
[0052] The winged airbag in Embodiment 1 above is further optimized as follows to ensure its stable attitude in the air.
[0053] like Figures 1-3 As shown, the left wing 103 of the airbag is provided with a left wing air passage 105, which runs through the front and rear ends of the left wing 103. That is, at the root of the left wing 103 (near the end of the airbag body 101), an air passage that runs through the left wing 103 is provided. This air passage is the left wing air passage 105. Similarly, at the root of the right wing 104 of the airbag (near the end of the airbag body 101), an air passage that runs through the right wing 104 is provided. This air passage is the right wing air passage 106.
[0054] It should be noted that for this type of winged airbag structure, the arrangement of the left wing air duct 105 and the right wing air duct 106 does not affect the sealing of the internal space of the left and right wings of the airbag.
[0055] The left wing air duct 105 and the right wing air duct 106 of the airbag are used to ensure the stability of the airbag's attitude in the air; especially in strong winds, the left wing air duct 105 and the right wing air duct 106 of the airbag can guide the airflow and ensure the stability of the airbag's attitude.
[0056] As an example, one or more airways can be provided for the left wing airway 105 and the right wing airway 106 of the airbag; preferably, the left wing airway 105 and the right wing airway 106 of the airbag are arranged symmetrically with respect to the axis of the airbag body 101.
[0057] As an example, both the left and right air ducts of the airbag (105 and 106) have tail fin airbags extending from their tails (refer to the tail of the "Ferrybird"). Specifically, the tail of the left air duct 105 has a left tail fin airbag that communicates with it, and the tail of the right air duct 106 has a right tail fin airbag that communicates with it. The tail fin airbags further enhance the stability of attitude control with the wingspan airbag. Both the left and right tail fin airbags have openings at the front and rear ends, with their front openings communicating with the corresponding air ducts.
[0058] As an example, the ventilation volume of the left wing airway 105 and the right wing airway 106 of the airbag is adjustable. By controlling the ventilation volume in the left wing airway 105 and the right wing airway 106 of the airbag, the steering control of the winged airbag can be achieved.
[0059] Example 3:
[0060] Based on the above embodiment 1 or embodiment 2, the winged airbag is further optimized as follows, so that the winged airbag can turn and pitch in the air.
[0061] Both the left wing air duct 105 and the right wing air duct 106 of the airbag have tail wing airbags extending from their tails (left tail wing airbag and right tail wing airbag, respectively). In order to achieve the turning of the winged airbag in the air, each tail wing airbag is equipped with an air duct ring. By tightening or loosening the air duct ring, the airflow through the tail wing airbag can be changed. Thus, by controlling the air duct rings on the left and right tail wing airbags, the airflow areas of the left and right tail wing airbags can be made different, which in turn makes the aerodynamic forces on the left wing 103 and the right wing 104 of the airbag inconsistent, thereby controlling the left and right turning of the winged airbag.
[0062] As an example, a power unit (such as a small propeller) can also be installed in the left wing air duct 105 and the right wing air duct 106 of the airbag to provide power for turning left and right.
[0063] To achieve pitch control of the winged airbag, tethering bolts are provided on the front and rear ends of the airbag body 101. One end of the forward pitch adjustment rope is connected to the tethering bolt on the front end of the airbag body 101, and the other end is wound around the forward pitch adjustment rope retraction unit (such as a drum) in the winged airbag load compartment 109. One end of the rear pitch adjustment rope is connected to the tethering bolt on the rear end of the airbag body 101, and the other end is wound around the rear pitch adjustment rope retraction unit (such as a drum) in the winged airbag load compartment 109. Thus, by controlling the retraction and release of the forward and rear pitch adjustment ropes, the pitch of the winged airbag can be controlled.
[0064] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
