Description

Suspended Aerostatic Platform Using Helium Balloons with Structural Reinforcement and Weather-responsive Safety Features

[0001] This invention relates to a suspended aerostatic platform utilizing helium balloons, combined with structural reinforcement and weather-responsive safety systems. It addresses the challenges of stability and safety in high-altitude suspended structures by integrating lightweight materials, advanced buoyancy control, and real-time environmental monitoring. The system employs helium-filled balloons, stabilizing gyroscopes, tether cables, and sensors to maintain balance and respond to weather conditions, ensuring safe operation. Power is supplied through solar panels with energy storage, supporting various onboard systems.

[0002] This versatile platform can be adapted for multiple uses, including observation decks, restaurants, event spaces, or research stations, providing safe and stable elevated environments in diverse settings.

[0003] B64B 1 / 50 - B64D 47 / 00 - B64B 1 / 40 - B64C 39 / 02

[0004] Aerostatic platforms utilizing buoyant gases like helium have been explored for decades, yet existing systems fail to address the critical challenges of structural stability, weather-responsive safety, and passenger utility in an integrated manner. Prior art reveals incremental advancements in tethered balloons, aerostat designs, and stabilization methods, but none of the existing systems combine the inventive features of our claimed patent as they face limitations in various aspects including:

[0005] 1. Structural Reinforcement and Payload Capacity

[0006] US4366936A - Aircraft having buoyant gas balloon

[0007] This patent describes a spherical super-pressure helium balloon with a rigid yoke for load-bearing, but it relies on propulsion (Magnus effect) for stabilization, omitting gyroscopic systems or composite platforms for passenger use.

[0008] RU2722087C1 - Tethered balloon

[0009] This patent proposes a tethered balloon with aerodynamic surfaces and tail stabilizers, yet its focus is on unmanned payloads and wind resistance, lacking modular safety features like polycarbonate railings or automated descent protocols.

[0010] CN104787297A - Tethered aerostat system

[0011] While disclosing helium balloons with restraining cables, this system is designed for surveillance payloads and lacks the structural reinforcement and passenger amenities of our invention.

[0012] Moreover, existing commercial systems like Helikites combine kites and balloons for lift but prioritize lightweight surveillance equipment over reinforced passenger platforms with thermal insulation.

[0013] 2. Stabilization and Weather Adaptation

[0014] US11130557B1 - Controlling lifting gas in inflatable structures

[0015] This patent discloses a helium-based passenger transport system but uses passive ballast adjustments rather than active gyroscopic stabilization or real-time sensor feedback.

[0016] US20140174854A1 - Cable-suspended passenger platform

[0017] While featuring an elevated passenger platform with safety mechanisms, this system relies entirely on mechanical cables for suspension without any aerostatic lift capability.

[0018] Furthermore, tethered aerostats (e.g., Ti-Chuan's design) employ aerodynamic shapes for wind resistance but lack algorithmic control of gyroscopes or buoyancy valves to counteract rotational oscillations.

[0019] 3. Safety and Passenger Utility

[0020] US11150646 - Emergency descent system

[0021] This system focuses on rescue mechanisms for suspended platforms but is not integrated with aerostatic lift systems or passenger-specific features.

[0022] US8899514B2 - Variable buoyancy airship

[0023] While demonstrating buoyancy control via gas valves, this airship design lacks the tethered platform configuration and passenger safety systems of our invention.

[0024] Other relevant examples of prior art emphasize mooring challenges (US4366936A) or emergency parachutes (US11150646), but none integrate seat belts, wind-triggered descent, and cable elevators into a unified system. Moreover, environmental monitoring balloons (e.g., High Altitude Science) are limited to scientific payloads and lack structural frameworks for human occupancy.

[0025] The claimed idea in this patent resolves these gaps through:

[0026] I. Integrated Stabilization: Combining gyroscopes with restraining cables and algorithmic feedback to maintain platform equilibrium, unlike passive tethers or propulsion-dependent designs found in US4366936A or CN104787297A.

[0027] II. Weather-Responsive Automation: Sensors and control systems dynamically adjust buoyancy (via gas valves) and stabilization (via gyroscopes), surpassing static super-pressure balloons or manual ballast systems like US11130557B1.

[0028] III. Passenger-Centric Design: A composite platform with anti-slip flooring, polycarbonate enclosures, and cable elevators addresses utility and safety unmet by cargo-focused aerostats such as Helikites or surveillance platforms like CN104787297A.

[0029] Overall, while prior art demonstrates isolated solutions for lift (US4366936A), wind resistance (RU2722087C1), or payload transport (Helikites), our claimed invention's combination of active stabilization, modular safety, and passenger infrastructure represents a non-obvious leap forward. This is further underscored by the absence of prior systems capable of maintaining a 30m-altitude platform with human occupants under variable weather conditions while incorporating all the novel features described herein.

[0030] This invention pertains to a suspended aerostatic platform that employs helium balloons for buoyancy, combined with advanced structural reinforcement and weather-responsive safety systems. The platform operates at a height of approximately 30 meters, providing a stable and secure environment for various applications. Its design integrates lightweight materials such as aluminum alloy and carbon fiber to ensure strength while minimizing weight, facilitating safe suspension and maneuverability.

[0031] Key features include a sophisticated balance control system utilizing stabilizing gyroscopes and tether cables to counteract wind and environmental forces. Multiple helium-filled balloons provide the primary lifting force, with sensors and automatic valves maintaining optimal buoyancy. Structural reinforcements, including reinforced composite floors and impact-resistant transparent panels, enhance durability and safety. Safety mechanisms such as restraining cables, protective railings, seat belts, wind and height sensors, and alarm systems ensure passenger and structural security during operation.

[0032] The platform also incorporates rapid response features for weather changes, allowing real-time adjustment of buoyancy and positioning. Power is supplied via solar panels, with energy stored in rechargeable batteries, supporting lighting, ventilation, and control systems. Overall, this invention offers a safe, flexible, and efficient solution for elevated platforms, combining buoyant aerostat technology with structural and environmental safety innovations.

[0033] Existing helium-based elevated platforms struggle to deliver safe, stable performance at heights around 30 meters due to fundamental limitations in their design approach. These systems typically rely on outdated passive stabilization methods that can't adequately compensate for environmental forces. When winds reach just 10 m / s, platforms often tilt beyond 15 degrees - enough to cause significant discomfort and safety risks for occupants. The lack of integrated active stabilization means these structures remain vulnerable to rotational forces, unpredictable oscillations, and cumulative structural stress.

[0034] The safety shortcomings are equally concerning. Current designs react to emergencies rather than preventing them, lacking automated systems that could trigger controlled descent when winds exceed 15 m / s or adjust helium pressure during sudden temperature changes. Occupant protections are often an afterthought, with few systems incorporating the layered safety features needed for reliable high-altitude operation.

[0035] Power systems present another limitation, as most platforms remain tethered to ground-based electricity. This dependence severely restricts where and how these structures can operate while leaving them vulnerable to power disruptions. Even when operational, they frequently sacrifice payload capacity for buoyancy efficiency, with most unable to reliably support more than 2,000 kg at 30-meter altitudes.

[0036] Our invention transforms this landscape through an integrated design philosophy. By combining gyroscopic stabilization with dynamic cable tensioning, we maintain platform orientation within a precise 5-degree tolerance even in challenging conditions. The system doesn't just respond to environmental changes - it anticipates them, automatically adjusting balloon pressure and activating safety protocols before conditions become hazardous.

[0037] The human element is central to our approach. Impact-resistant enclosures provide clear views without compromising safety, while automated restraints and emergency systems operate seamlessly in the background. Solar-hybrid power delivers true operational independence, and ensure an eco-friendly, energy-efficient approach. Despite the robust functionality, the platform maintains an impressive 2,900 kg payload capacity through careful material selection and structural optimization.

[0038] This holistic solution represents a new standard for elevated platforms, finally achieving what previous systems couldn't - reliable performance that never forces operators to choose between safety, stability, and practicality. By addressing these longstanding limitations simultaneously rather than individually, we've created a platform that's as functional as it is innovative.Solution of Problem

[0039] The present invention is a suspended aerostatic platform designed to operate at approximately 30 meters above ground, employing helium balloons for buoyancy, combined with advanced structural reinforcement and weather-responsive safety systems to ensure stability and safety under various environmental conditions.

[0040] Structure and Materials:

[0041] The core framework includes four reinforced aluminum poles, each 3.5 meters long with a 10 cm diameter, connected via steel brackets to form a sturdy supporting skeleton. The main platform measures 6 meters by 6 meters, constructed from composite materials with thermal insulation and anti-slip surfaces for safety and comfort. The platform is enclosed by eight impact-resistant polycarbonate panels, each 12 meters high and 2 cm thick, providing visibility and protection against wind and debris.

[0042] The roof hosts four helium balloons, each with a volume of approximately 250 m³, constructed from multi-layer polyethylene with UV and pressure-resistant coatings to withstand weather exposure. These balloons are elliptical, designed to produce a combined buoyant force of roughly 28,806 Newtons, sufficient to lift a total estimated weight of 2,900 kg—including the structure, equipment, and 12 guests or users averaging 75 kg each.

[0043] Buoyancy and Stabilization System:

[0044] The helium balloons are connected to the platform via stainless steel restraining cables, each 30 meters long, coated with polyethylene for weather resistance. The helium within each balloon is regulated by internal pressure sensors and automatic gas valves, maintaining optimal buoyancy despite environmental changes. The total helium volume required is approximately 2,487 m³, computed using [Formula. 1] which is the buoyancy formula.

[0045] To stabilize the platform against wind and movement, two self-adjusting gyroscopes are mounted at the center of mass, actively counteracting rotational oscillations. Additional four restraining cables extend from the platform's corners to ground anchors or towers, limiting horizontal displacement and ensuring positional stability.

[0046] Materials and Components:

[0047] Main poles: 4 reinforced aluminum, 3.5 meters long, 10 cm diameter.

[0048] Side poles: 8 lightweight aluminum, 2 meters long.

[0049] Floor: 6 x 6 meters, made from composite materials with anti-slip and thermal insulation layers.

[0050] Walls: 8 impact-resistant polycarbonate panels, each 12 meters high.

[0051] Roof balloons: 4 large helium balloons (~250 m³ each).

[0052] Safety features: 8 impact-resistant polycarbonate railings (1.2 meters high), reinforced nylon seat belts, wireless alarm systems, wind and height sensors.

[0053] Environmental Control and Power:

[0054] Four solar panels (each 1.5 x 1.5 meters) with monocrystalline solar cells are mounted on the roof to generate electrical power. The energy is stored in rechargeable lithium-ion batteries, supporting LED ambient lighting, ventilation, and climate control systems. The ventilation system is low-power and battery-operated, ensuring air quality and temperature regulation.

[0055] Sensors and Automated Safety:

[0056] Environmental sensors monitor wind speed, altitude, and weather, feeding data to control systems that automatically adjust buoyancy and stability. During adverse conditions, the system can initiate controlled descent or stabilize the platform through gas regulation and gyroscopic adjustments.

[0057] Access and Transportation:

[0058] Guests are transported via a cable elevator powered by an electric motor, capable of carrying four persons (~240 kg). The elevator connects to a ground tower or structure and features guide rails and safety mechanisms for secure boarding and disembarking. A movable entrance platform facilitates safe entry and exit.

[0059] Operational Mechanics:

[0060] The helium balloons are equipped with internal pressure control valves, monitored by sensors to maintain constant buoyancy. The combined buoyant force of roughly 28,806 N supports the total weight of approximately 2,900 kg. Restraining cables and gyroscopes work synergistically to counteract wind-induced oscillations, ensuring stability. Power from solar panels sustains all onboard systems, with backup batteries ensuring continuous operation. Environmental sensors enable real-time adjustments, maintaining safety and stability in changing weather conditions.

[0061] The buoyancy and weight calculations along with equations related to structural features of the invention are included in the example section of the patent application as formulas.

[0062] In short, this invention integrates lightweight structural components, precise buoyancy control, environmental responsiveness, and comprehensive safety features—using approximately 2,487 m³ of helium, four large balloons, and advanced stabilization systems—to provide a safe, stable, and versatile elevated platform suitable for observation decks, restaurants, research stations, or event spaces, capable of operating reliably in diverse conditions.Advantage Effects of the Invention
