Description

Technical Field

[0001] This invention belongs to the technical field of aerospace vehicle floating structure, buoyancy gas closed-loop storage and cavity shape switching, specifically involving a layered independent compartment gas staged compression storage and cavity vacuum forming device. Background Technology

[0002] Existing traditional airships all adopt an integral single airbag structure, which is simple in structure but has many fatal flaws: First, the overall airbags are exposed, making the aircraft bulky and unable to achieve a rigid, streamlined hull shape. It has a high degree of visual recognition but poor concealment, and cannot be adapted to the futuristic compact warship design. Second, the single-airbag structure has the risk of single-point failure. Damage at any point will lead to overall air leakage and complete loss of buoyancy, resulting in extremely poor safety. Third, traditional airbags cannot completely contain gas and close the cavity vacuum, and cannot vacate the internal compartments. The spacecraft always retains the floating cavity structure, which cannot meet the needs of compact space navigation, expansion of human habitation compartments, and equipment integration and installation. Fourth, traditional inflation and deflation systems lack the ability to perform graded compression and zoned pressure control, resulting in coarse pressure control and poor adaptability to various operating conditions, including high and low altitudes and round trips between Earth and space. They are unable to meet the multi-mode switching requirements of transatmospheric aerospace vehicles.

[0003] In summary, existing airbag structures cannot meet the requirements of high-end aerospace equipment that features rigid ship hull forming, fully gas-closed-loop storage, solid vacuum cavity, and free switching between multiple operating modes. A new structural solution is urgently needed to address these technical shortcomings. Summary of the Invention Purpose of the invention

[0004] To address the shortcomings of existing technologies, this invention provides a layered independent compartment gas staged compression and storage and cavity vacuum forming device, which solves the problems of traditional airships being limited in shape, unable to be solidly stored, prone to overall failure when damaged, having limited operating conditions, and unable to adapt to space travel configurations. It enables free switching between three states: solid hard form on the ground, floating form in the atmosphere, and compact space travel form. Technical solution

[0005] A layered independent compartment gas staged compression and storage and cavity vacuum forming device includes a rigid ship hull shell (6), a honeycomb independent sealed compartment (3) group separated by sealing bulkheads (1), a staged flow guide pipeline assembly, a multi-stage booster compressor unit (4), a composite gas storage tank group (5), a vacuum pump unit (7), and an electrically controlled reversing valve group (9); the staged flow guide pipeline assembly adopts a staged structure of "branching and converging - step-by-step pressurization".

[0006] The interior of the rigid hull shell (6) is divided into a large number of independent, non-interconnected sealed compartments (3) by a sealing partition (1). Each independent sealed compartment (3) is equipped with a graded flow guide pipe (10) and an integrated compartment independent electronic control shut-off valve (2) with an integrated vacuum monitoring module. The floating gas inside the independent sealed compartment (3) is pressurized step by step by a multi-stage pressurization compressor unit (4) and collected into the composite gas storage tank group (5) inside the hull. After the gas is collected, the vacuum pump unit (7) is used to extract the vacuum from the cavity of all independent sealed compartments (3), so that the flexible compartments are completely attached to the inner wall of the sealing partition (1). There are no extra cavities in the hull sandwich, and the whole presents a solid rigid ship structure. The sealing partition (1) and the rigid hull shell (6) together form a planar honeycomb sandwich structure, and the independent sealed compartments (3) are filled in the grid pores of the honeycomb structure. The switchable independent sealed compartment (3) refers to a compartment whose on / off state is controlled by an integrated compartment independent electrically controlled shut-off valve (2) with an integrated vacuum monitoring module. When the valve is closed, the compartment remains completely sealed and isolated; when the valve is open, the compartment can exchange gases with the graded flow pipeline. In this invention, "independent sealed compartment" and "flexible compartment" both refer to the honeycomb switchable independent sealed compartment as described in claim 1.

[0007] When an aerial operation is required, the composite gas storage tank group (5) stabilizes and releases pressure, and the floating gas is evenly filled into each independent sealed compartment (3) through the graded guide main pipeline (8) and the graded guide branch pipeline (10), so as to quickly restore the overall buoyancy; in high-altitude and orbital conditions, the gas can be recovered again and the cavity can be vacuumed and contracted to form a compact space travel configuration. Beneficial effects

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: Completely subverts the traditional airbag structure: adopts a honeycomb independent sealed compartment (3) design, with no exposed airbags, and a completely solid hard appearance when docked on the ground. Outsiders cannot identify the floating principle, and the confidentiality, structural aesthetics, and adaptability of the sci-fi configuration are greatly improved; Extremely high fault tolerance: each compartment is independently controllable, and local damage is isolated separately, without affecting the buoyancy and safety of the hard hull, completely solving the fatal problem of traditional airships leaking when damaged; Free switching between three modes: perfectly realizes the switching between three configurations: solid docking on the ground, atmospheric floating cruise, and tight space navigation, adapting to all airspace conditions in low altitude, near space, and outer space; Extremely high gas closed-loop utilization rate: staged compression and storage with extremely low gas loss, combined with vacuum forming technology, completely emptys the interlayer space, which can be expanded into human habitation cabins, equipment cabins, and storage cabins, maximizing space utilization; compatible with all types of aerospace equipment: it can be used for giant transatmospheric interstellar warship-like airborne vehicles, as well as small and medium-sized stratospheric platforms, high-altitude cargo airships, and orbital dwelling equipment, with extremely strong versatility and extremely high industrialization value.

Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings.

[0012] The device of this invention is integrated and installed inside the interlayer of a rigid hull. The entire interlayer is divided into hundreds to thousands of independent sealed compartments (3) of uniform specifications by a sealing partition (1). All independent sealed compartments (3) are not interconnected and are independently sealed. The sealing partition (1) and the rigid hull shell (6) together constitute an integral rigid honeycomb interlayer load-bearing structure. When the independent sealed compartments (3) are evacuated and contracted, the sealing partition (1) acts as an internal reinforcing rib, forming a high-strength load-bearing system similar to a sandwich panel with the rigid hull shell (6). It can evenly withstand external atmospheric pressure and does not need to rely on internal gas pressure to maintain the shape of the hull. This structure also serves as the main load-bearing keel of the airship, greatly improving the rigidity of the rigid hull structure and solving the problem of traditional soft airships relying on gasbag pressure to maintain their shape and having poor wind resistance. The composite gas storage tank group (5) includes multiple groups of normal temperature high pressure gas storage tanks with different pressure levels. Among them, the cylindrical tank is a medium and high pressure conventional gas storage tank with high space utilization and is used to store most of the floating gas used daily. The spherical tank is an ultra-high pressure emergency gas storage tank. Although the space utilization is low, its stress distribution is uniform and its structural strength is extremely high, which can ensure safety under extreme working conditions and serve as the last buoyancy bottom protection method. Ground parking status

[0013] The rigid hull is stationary and docked. The electrically controlled reversing valve group (9) opens the gas storage passage, and the multi-stage booster compressor group (4) starts in sequence. According to the hierarchical logic of low-pressure collection, medium-pressure boosting, and high-pressure storage, the helium inside all independent sealed compartments (3) is compressed step by step and stored in the composite gas storage tank group (5) inside the hull. After the gas storage is completed, the electrically controlled reversing valve group (9) closes the gas storage passage and starts the vacuum pumping unit (7) to extract a high vacuum into all independent sealed compartments (3), so that all flexible compartments are completely attached to the inner wall of the sealing bulkhead (1), with no protrusions or cavities in the interlayer. The rigid hull presents a complete, regular, and solid rigid warship appearance. The internal compartments are complete and usable, and can be used for normal personnel passage, equipment layout, and external display. It has no floating equipment characteristics. The composite gas storage tank group (5) is symmetrically distributed along the longitudinal axis of the rigid hull. The medium and high pressure gas storage tanks are evenly arranged in the middle of the hull, and the ultra-high pressure emergency gas storage tanks are concentrated at the center of gravity to ensure that the center of gravity of the rigid hull remains stable during the gas filling and releasing process. Take-off and flight status

[0014] By switching the working mode through the electronic control system, the electronically controlled reversing valve group (9) opens the gas filling passage, and the composite gas storage tank group (5) releases pressure at a constant speed. The floating gas is distributed and balanced through the graded guide main pipeline (8) and simultaneously filled into each group of independent sealed compartments (3) through the graded guide pipe branch (10). All independent sealed compartments (3) expand synchronously and uniformly, and stably generate overall lift. Combined with the rotor power, it can achieve smooth take-off, low-altitude cruise, and stratospheric stay. During flight, the pressure of the local independent sealed compartments (3) can be individually adjusted by the integrated compartment independent electronic control shut-off valve (2) with integrated vacuum monitoring module to achieve attitude fine adjustment and extremely strong aerodynamic stability. Space travel status

[0015] After the rigid hull arrives in near space and transatmospheric airspace, the multi-stage pressurization compressor unit (4) is restarted to recover the floating gas in all independent sealed compartments (3) to the composite gas storage tank group (5). The vacuum pump unit (7) is used to evacuate and close the interlayer cavity, and the rigid hull restores its compact solid structure, greatly reducing the wind resistance of space travel and reducing the redundant weight of the structure, making it suitable for rocket-powered deep space flight and orbital stay operations.

[0016] Fault Protection Implementation: If an independent sealed compartment (3) leaks or breaks during flight, the integrated compartment independent electrically controlled shut-off valve (2) with integrated vacuum monitoring module automatically detects the pressure abnormality and feeds it back to the control system. The system immediately closes the integrated compartment independent electrically controlled shut-off valve (2) with integrated vacuum monitoring module corresponding to the independent sealed compartment (3), isolating the faulty chamber separately. All other independent sealed compartments (3) maintain normal pressure, and the buoyancy and attitude of the rigid hull are not affected, achieving full-process safe and redundant operation. The integrated compartment independent electrically controlled shut-off valve (2) with integrated vacuum monitoring module adopts a dual-redundant communication protocol, which can stably execute opening, closing and isolation commands in complex environments such as strong electromagnetic interference and high-altitude radiation, ensuring the system reliability during transatmospheric flight.

[0017] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
