Description

Technical Field

[0001] This invention relates to the field of aviation firefighting ground support technology, specifically to a low-cost ground support system for rapid takeoff of urban aviation firefighting flight delivery vehicles. Background Technology

[0002] The aforementioned "flying delivery vehicle" is one of the core invention contents of the patent application "A method for aerial firefighting suitable for large and medium-sized cities" (application number: 2026105158974), hereinafter referred to as the "patent application." Its typical application is a heavy helicopter, which is used to carry future urban aerial firefighting professional firefighting equipment—the aerial delivery firefighting combination—to complete rapid firefighting operations in urban aerial firefighting, achieving "early detection and early suppression" of urban fires. However, it is necessary to ensure that the heavy helicopter used as the flying delivery vehicle can take off rapidly within 1 minute after receiving the firefighting dispatch order.

[0003] For heavy helicopters that are completely grounded, achieving a rapid takeoff within one minute is not feasible. It is necessary to create the necessary ground support technology to enable such a rapid takeoff within one minute.

[0004] In the military field, it is entirely feasible for heavy helicopters to take off rapidly within one minute. The traditional ground support methods rely on either idling the helicopter's engine for warm-up or allowing the APU to operate continuously. These methods are feasible for occasional or short-term applications. However, applying this approach to urban aerial firefighting, which requires 24 / 7 / 365 readiness, presents significant challenges. A single traditional ground support system supporting the rapid takeoff of only one heavy helicopter would incur annual fuel or electricity costs of hundreds of thousands or even millions of yuan. Furthermore, it would require multiple ground crew members on duty 24 / 7, resulting in high labor costs. The dispersed equipment and cumbersome operation highlight the industry pain points of unreliably ensuring the rapid takeoff of heavy helicopters within one minute. Moreover, prolonged high-load operation would accelerate wear and tear on helicopter engines, APUs, and other components, further increasing maintenance costs.

[0005] The construction, operation, and maintenance costs of aerial firefighting are entirely supported by public finances. If a city needs to deploy multiple aerial firefighting stations (hereinafter referred to as "aerial fire stations"), each station will require multiple sets of traditional ground support systems to serve multiple on-duty airlift vehicles—heavy helicopters. This will become a heavy financial burden for the city and even the nation. It will severely restrict the operational effectiveness of the airlift vehicles described in the patent applications, especially the unit firefighting units, hindering the nationwide promotion and long-term sustainable operation of aerial firefighting.

[0006] To address the aforementioned issues, there is an urgent need for a low-cost ground support system that can ensure rapid takeoff of airborne delivery vehicles within one minute, while significantly reducing energy consumption, minimizing manpower requirements, and enabling long-term 24-hour standby. This system would solve industry pain points, improve the feasibility of promoting aerial firefighting for airborne delivery vehicles, and provide solid ground support for the application of patented technologies. Summary of the Invention

[0007] Purpose of the Invention: To address the problems of high energy consumption, large manpower requirements, and excessively high total annual operating costs associated with traditional ground support systems for the rapid takeoff of heavy helicopters used as aerial firefighting vehicles in urban areas, which are difficult to reliably guarantee a 1-minute rapid takeoff, this invention provides a low-cost ground support system that supports and ensures the takeoff of heavy helicopters within 1 minute. This system achieves low energy consumption, minimal manpower, and 24-hour long-term standby, reducing support costs and enhancing the system's promotional value. Furthermore, this system closely integrates with the aerial delivery vehicle / unit firefighting unit described in the patent application, achieving synergistic compatibility with the patent application and further strengthening the integrated "air delivery + ground support" system for aerial firefighting, thereby enhancing the practical significance and promotional value of the entire aerial firefighting system.

[0008] Technical Solution: The low-cost ground support system for rapid urban aerial firefighting includes: a low-power ground preheating and insulation unit, a high-power intelligent ground start-up power supply (GPU), a fully automatic status monitoring unit, and pre-installed auxiliary units. The operation and maintenance of this low-cost ground support system achieves low energy consumption and minimal manpower. All units work collaboratively to form a complete, rapid-takeoff, low-cost ground support chain. This low-cost ground support system supports 24-hour long-term combat readiness and allows heavy helicopters, serving as on-duty flight delivery vehicles, to take off within one minute of receiving a fire alarm dispatch order.

[0009] Furthermore, the ground-based low-power preheating and insulation unit includes: a zoned heating module, an intelligent temperature control module, and a quick-disengagement module. The zoned heating module is used to maintain a constant temperature for 24 hours on devices / parts of the heavy helicopter, such as engine oil, gearbox, and coolant, which require reaching the specified operating temperature for takeoff, eliminating the need for the heavy helicopter's internal combustion engine to idle and warm up, thus reducing energy consumption. The intelligent temperature control module uses closed-loop temperature control logic, with a temperature control accuracy of ±1℃, ensuring that the temperature of key engine components remains stable within the allowable direct start-up temperature range. The quick-disengagement module can automatically disengage within 0.5 seconds of the heavy helicopter starting, without affecting takeoff safety.

[0010] Furthermore, the ground-based low-power preheating and insulation unit adopts both mains power supply and backup power supply modes. When the mains power is interrupted, it automatically switches to the backup power supply to ensure uninterrupted 24-hour constant temperature preheating and insulation.

[0011] Furthermore, the high-power intelligent ground start-up power supply (GPU) adopts SiC devices and a modular design to replace the helicopter APU for long-term operation, reducing fuel consumption and equipment wear.

[0012] Furthermore, the fully automatic status monitoring unit includes: a wireless data acquisition module, an AI fault early warning module, and a remote monitoring terminal. The wireless data acquisition module collects the working parameters of the heavy helicopter and each support unit in real time. The AI ​​fault early warning module can provide early warning of equipment abnormalities. The remote monitoring terminal supports remote operation by a single person and can monitor the support status of multiple heavy helicopters simultaneously.

[0013] Furthermore, the pre-installed and pre-attached auxiliary unit includes: a spreader fixing module, a quick-release lock, and a load detection module. The spreader fixing module is adapted to the spreader interface of the heavy helicopter, the quick-release lock ensures rapid disengagement after receiving an alarm, and the load detection module provides real-time feedback on the load status to ensure reliable mounting of firefighting equipment. The pre-installed and pre-attached auxiliary unit is used to pre-install and pre-attach aviation firefighting equipment and slings to the heavy helicopter in advance. After receiving an alarm, they can be quickly disengaged without affecting the rapid takeoff operation of the heavy helicopter and reducing the ground preparation time before the heavy helicopter takes off.

[0014] Furthermore, the high-power intelligent ground start-up power supply (GPU) has a one-button start-up control function, which meets the power supply requirements of heavy helicopter start-up and avionics systems. In standby mode, the power consumption is close to zero, which supports further reduction of operating costs.

[0015] Furthermore, the fully automatic status monitoring unit is used to collect data on the engine temperature, hydraulic status, fire-fighting equipment mounting status, and working status of each support unit of the heavy helicopter in real time. It supports 4G / 5G wireless transmission and single-person remote monitoring, eliminating the need for manual on-site inspection.

[0016] Furthermore, the low-cost ground support system adopts a modular integrated design, enabling rapid deployment and adaptability to temporary fire support sites without fixed airports. The system can operate stably within an ambient temperature range of -40℃ to +55℃ without requiring additional insulation equipment, thus adapting to the environmental needs of aviation firefighting in different cities. The low-power ground preheating and insulation unit can be used alone or in combination with solar heating. The low-power ground preheating and insulation unit includes an external purely physical insulation structure that does not affect the rapid takeoff of heavy helicopters, supporting further energy savings. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments. This embodiment takes the rapid take-off of the AC313A heavy helicopter (i.e., the flight delivery vehicle in the unit fire extinguishing unit described in the patent application) as an example to illustrate the specific structure, working process and cost advantages of the system. At the same time, relevant content will be supplemented and improved in conjunction with the key points of the claims. Example 1: Overall Structure of a Low-Cost Ground Support System This embodiment's low-cost ground support system is deployed at various urban airborne fire stations. It is a dedicated ground support facility for heavy helicopters—the flight delivery vehicle for which a patent has been filed—providing a complete and rapid takeoff ground support link for the heavy helicopters of the on-duty firefighting unit. This enables heavy helicopters to achieve rapid takeoff within one minute, low energy consumption, minimal manpower, and long-term 24-hour combat readiness. One low-cost ground support system serves only one heavy helicopter in the on-duty firefighting unit of the airborne fire station. The specific structure is as follows:

[0018] Ground low-power preheating and insulation unit: It adopts a domestically customized low-power electric heating and insulation system with a purchase cost of 60,000 yuan. It includes a zone heating module, an intelligent temperature control module and a quick disconnect module. The zone heating module corresponds to the engine oil, gearbox and coolant parts of the AC313A heavy helicopter, and is equipped with heating devices, typically dedicated heating pads, to achieve precise heating and avoid ineffective energy consumption. The intelligent temperature control module adopts closed-loop temperature control logic, which collects the temperature of key engine components in real time through temperature sensors and controls the temperature within 15-25℃ (ensuring the optimal temperature range for direct engine start-up), with a temperature control accuracy of ±1℃. The quick-disengagement module adopts an electromagnetic control structure, which automatically disengages from the heavy helicopter components within 0.5 seconds after receiving the start signal at the moment of heavy helicopter start-up, without affecting the heavy helicopter take-off operation and the safety of the air-dropped fire extinguishing combination and the aviation basket. This unit is powered by mains electricity during normal operation, with a rated power consumption of 1.0kW. It operates at a constant temperature for 24 hours without additional fuel consumption and does not require the idling warm-up of a heavy helicopter engine. This ensures that the engine can be started directly after receiving the start command, without any warm-up waiting time. This unit is equipped with its own power supply, which can be expanded to a maximum power of 5kW. This ensures that the unit can continue to provide power support when the mains power is interrupted, and that the constant temperature preheating and insulation is uninterrupted for 24 hours. Since this system requires 24-hour operation and cannot be shut down 365 days a year, electricity cost is a core component of the total cost. To further reduce energy consumption and control costs, the following two auxiliary power-saving methods are recommended, which can be used individually or in combination: (1) Utilize solar energy resources for heating: Deploy small solar thermal systems in the air and fire station support area. The solar thermal system absorbs heat through solar collectors and stores heat in conjunction with insulated water tanks. During periods of sufficient sunlight (such as daytime), it provides auxiliary heating for the ground low-power preheating and insulation units, reducing the consumption of mains electricity. The solar system can be deployed in a modular manner, and the purchase cost can be controlled at 20,000 to 30,000 yuan. Long-term use can significantly reduce electricity expenses and is in line with the concept of green energy saving.

[0019] (2) Add external insulation structure for heavy helicopters: On the premise of not hindering the take-off of heavy helicopters and not affecting the operation of aerial fire-fighting combination and aerial basket loading, add a detachable insulation structure (such as insulation cover, thermal cover, insulation coating, etc.) to the external of the heavy helicopter of the fire-fighting unit on duty. The insulation structure is made of lightweight, fireproof and easy-to-disassemble materials, which can be quickly installed and removed, improve the insulation effect of the fuselage and engine parts of heavy helicopters, reduce the power consumption of ground low power preheating insulation unit, and is expected to reduce annual electricity expenditure by 15%-20%.

[0020] High-power intelligent ground start-up power supply (GPU): It adopts a domestically produced high-power intelligent GPU with a purchase cost of 90,000 yuan. It adopts SiC devices and modular design, has a one-button start-up control function, and a start-up response time of ≤20 seconds (the actual start-up response time in this embodiment is 15 seconds, which meets the upper limit requirement of the claims). The power consumption in standby mode is ≤50mW, which is close to zero. It can directly replace the long-term operation of the APU of heavy helicopters, avoid the high fuel consumption of APU, further reduce operating costs, and is compatible with internal combustion engine-driven heavy helicopters. It fully meets the power supply requirements of the rapid start-up and avionics system of heavy helicopters, and ensures that the heavy helicopter can quickly connect to the aerial drop fire extinguishing combination and the preparation work for the delivery of the aerial basket after the start-up.

[0021] Fully Automated Status Monitoring Unit: Purchase cost 10,000 RMB, including a wireless data acquisition module, an AI fault early warning module, and a remote monitoring terminal. The wireless data acquisition module is equipped with sensors on the engine, hydraulic system, and sling attachment points (for mounting aerial firefighting equipment and aerial baskets) of the heavy helicopter (heavy helicopter unit firefighting unit). These sensors collect key parameters in real time, such as engine temperature, hydraulic status, firefighting equipment attachment status, and door closure status, and transmit them to the remote monitoring terminal via 4G / 5G wireless transmission. The AI ​​fault early warning module has a built-in fault identification algorithm that can provide early warning of equipment anomalies (such as heating pad failure, loose attachments, hydraulic anomalies, etc.) up to 72 hours in advance. It automatically generates a maintenance list to remind staff to handle issues promptly, avoiding impact on the emergency response of the firefighting unit and reducing maintenance costs. The remote monitoring terminal is deployed in the duty room of the aviation fire station, supporting remote monitoring. It allows for single-person remote operation and can simultaneously monitor the status of two AC313A heavy helicopters (i.e., two on-duty firefighting units) without requiring manual on-site inspection.

[0022] Pre-installed auxiliary unit: Includes quick-release latches, spreader fixing modules, and load detection modules. No additional specialized equipment is required. Utilizing the existing spreader of the heavy-duty helicopter (heavy-duty helicopter of the unit fire extinguishing unit), and equipped with dedicated quick-release latches (cost included in the ground low-power preheating and insulation unit), the quick-release latches ensure reliable mounting of firefighting equipment. No manual confirmation of the locking status is needed after receiving an alarm. The load detection module is linked to the fully automatic status monitoring unit, providing real-time feedback on the mounting status to ensure safe takeoff. This unit allows for one-time pre-installation and pre-attachment of firefighting equipment such as aerial-dropped fire extinguishing assemblies and aerial baskets, as well as slings, enabling long-term standby. After pre-installation, the load detection module provides real-time feedback on the mounting status to ensure reliable locking. Routine inspections are only required once a month to check spreader wear, latch locking status, and the integrity of aerial-dropped fire extinguishing assemblies and aerial baskets. Repeated disassembly and adjustment before each deployment is eliminated, significantly reducing ground operations and ensuring rapid takeoff within one minute.

[0023] This system supports stable operation in environments ranging from -40℃ to +55℃, is suitable for 24-hour long-term standby scenarios at urban aviation fire stations, and can be operated by a single person on a part-time basis without the need for professional aircraft maintenance personnel to be on duty 24 hours a day. Each unit adopts a modular design, with a deployment time of ≤30 minutes, and can be adapted to temporary fire support sites without fixed airports, possessing rapid deployment capabilities. Example 2: System Operation Process (Ensuring Takeoff within 1 Minute) The system's operation is divided into a standby state and a takeoff state, and the entire process revolves around the rapid takeoff requirements of the AC313A heavy helicopter on duty, as detailed below:

[0024] Standby mode (24-hour long-term standby): The ground low-power preheating and insulation unit operates continuously (can be combined with solar heating and external insulation structure for power saving). When the mains power is normal, it uses mains power; when the mains power is interrupted, it automatically switches to a backup power source (power limit 5kW) to maintain the engine oil, gearbox, and coolant temperatures of the AC313A heavy helicopter at 15~25℃. Annual power consumption is 8760 kWh (1.0kW × 24h × 365d). Based on an industrial electricity price of 0.8 yuan / kWh, the annual electricity cost is 7,008 yuan. If two power-saving methods are used, the annual... Electricity costs can be reduced to 5,600-6,000 yuan; the high-power intelligent GPU is in standby mode with power consumption close to zero and no additional energy consumption; the fully automatic status monitoring unit collects key parameters in real time (including the mounting status of aerial fire extinguishing combination and aerial basket), and the remote monitoring terminal displays them in real time. Staff can be on duty by one person at a time (which can be combined with other work of the fire station), without the need for dedicated personnel to be on duty 24 hours a day; the pre-installed auxiliary unit keeps the aerial fire extinguishing combination, aerial basket and other fire-fighting equipment in the pre-installed and pre-attached state, and the mounting detection module provides real-time feedback that the mounting is normal, ensuring that the unit fire extinguishing unit can be started at any time.

[0025] Initiating takeoff status (ensuring takeoff within 1 minute): Step 1: Upon receiving the fire alarm instruction, the aviation fire station staff sends an activation signal via the remote monitoring terminal, taking ≤5 seconds; Step 2: After receiving the start signal, the high-power intelligent GPU completes the start-up within 15 seconds (≤20 seconds, meeting the upper limit of the claims) to provide stable power supply to the heavy helicopter avionics system and start-up system, ensuring the normal operation of the aerial fire-fighting combination and the aerial basket mounting control system; Step 3: After receiving the start signal, the quick-release module of the ground low-power preheating and insulation unit automatically detaches from the heavy helicopter components within 0.5 seconds. At the same time, the quick-release latch of the pre-installed auxiliary unit is locked, which does not affect takeoff and subsequent airdrop firefighting operations. Step 4: After receiving the instruction, the pilot directly starts the heavy helicopter engine (no warm-up is required, the engine is already at the start-up temperature), and at the same time confirms through the heavy helicopter cockpit display unit that the hydraulic, load-bearing (airdrop fire extinguishing combination, aviation basket), and cabin door statuses are normal, which takes ≤30 seconds. Step 5: After confirming that all conditions are normal, the pilot operates the heavy helicopter to take off and rush to the fire scene to carry out the aerial firefighting mission, which takes ≤10 seconds; The entire start-up and takeoff process takes ≤60 seconds, meeting the mandatory requirement of "taking off within 1 minute". The entire process requires no on-site assistance from ground personnel and can be completed with the cooperation of pilots and remote monitoring personnel, ensuring that the unit fire extinguishing unit can respond quickly and handle fires efficiently. Example 3: System Cost Accounting (Purchase Cost + Annual Operating Cost) The cost of the low-cost ground support system in this embodiment is calculated as follows, all based on the 24-hour standby mode of the AC313A heavy helicopter urban air fire station (based on the calculation of 2 commonly used on-duty fire fighting units (the cost of other on-duty units is adjusted proportionally).

[0026] Purchase cost (one-time investment): Ground low-power preheating and insulation unit: 60,000 yuan (including quick-release lock, hoisting fixing module and load detection module; if a solar heating system is added, an additional 20,000-30,000 yuan is required; if an external insulation structure is added, an additional 5,000-10,000 yuan is required; the self-contained power supply can be integrated into this unit without additional purchase cost). High-power intelligent ground starting power supply (GPU): 90,000 yuan; Fully automatic status monitoring unit: 10,000 yuan; Pre-installed auxiliary unit: 0 yuan (the cost of core components is already included in the ground low-power preheating and insulation unit); The total purchase cost of the system is 60,000 + 90,000 + 10,000 = 160,000 yuan (excluding power-saving auxiliary facilities), which is far lower than that of imported similar systems (350,000 yuan) and only about 0.2% of the total cost of a heavy helicopter (unit fire extinguishing unit heavy helicopter), with an extremely low investment ratio. If power-saving auxiliary facilities are added, the total purchase cost can be controlled at 185,000-200,000 yuan, and the additional investment can be recovered through electricity cost savings in the long term.

[0027] Annual operating costs: (1) Electricity cost: The ground low-power preheating and insulation unit consumes 8760 kWh of electricity per year, at RMB 0.8 / kWh, and the annual electricity cost is approximately RMB 0.7 million; if two power-saving methods are adopted, the annual electricity cost can be reduced to RMB 0.56-0.60 million; the standby power consumption of the GPU is negligible, and there is no additional electricity cost; the self-contained power supply is only activated when the mains power is interrupted, and the annual power consumption is negligible; (2) Maintenance costs: The heating pad and temperature controller of the ground low-power preheating and insulation unit need to be replaced once a year, costing about RMB 3,000; the GPU needs to be routinely tested once a year, costing about RMB 1,000; the fully automatic status monitoring unit needs to be calibrated once a year, costing about RMB 1,000; if a solar heating system is added, the pipeline needs to be inspected once a year, costing about RMB 1,000; the total annual maintenance cost is approximately RMB 5,000 to RMB 6,000. (3) Labor costs: The single-person part-time duty model can be combined with the existing staff of the fire station, and there is no need to recruit additional professional maintenance personnel. The annual labor cost is approximately RMB 40,000. The total annual operating cost of the system is RMB 52,000-58,000 (including maintenance of power-saving auxiliary facilities), which is 93.0%-93.5% lower than the traditional APU long-term standby mode (annual operating cost of RMB 800,000) and 41.7%-43.7% lower than the imported ground support system (annual operating cost of RMB 99,500). It is within the affordability range of urban finances and has the value of being promoted throughout the region.

[0028] Lifecycle cost advantages: This system has no high fuel consumption equipment, avoiding the wear and tear caused by the long-term operation of the engine and APU in the traditional mode. It can extend the service life of the heavy helicopter (unit fire extinguishing unit heavy helicopter) engine by more than 30%, reducing the annual maintenance cost of heavy helicopter by about 300,000 yuan. At the same time, the reduced manpower mode reduces labor costs by 120,000 yuan per year (compared to the traditional 2-person three-shift mode). Long-term use can further reduce the lifecycle cost. If the power-saving auxiliary method is adopted, an additional 1,000-1,400 yuan in electricity costs can be saved per year, making the lifecycle cost advantage even more significant. Example 4: System Adaptability and Promotional Value The low-cost ground support system of this embodiment is not only compatible with the AC313A heavy helicopter, but can also be adapted to other heavy helicopters such as the Mi-171 and Z-8 by adjusting the heating power of the ground low-power preheating and insulation unit and the output parameters of the GPU (all of which can be used as heavy helicopters with unit fire extinguishing units in the patent application). It has strong adaptability. The system adopts a modular design, with a deployment time of ≤30 minutes. It can be adapted to temporary fire support sites without fixed airports and meet the aviation fire support needs of different areas of the city.

[0029] While ensuring rapid takeoff within 1 minute, the system achieves the goals of low energy consumption, minimal manpower, and long-term standby. It boasts low purchase costs and controllable operating costs, with annual operating costs only 6.5%-7.2% of the traditional model. This completely solves the industry pain point of excessively high ground support costs for heavy helicopter aerial firefighting. Simultaneously, this system is closely integrated with its patented patents, providing dedicated ground support for unit firefighting units and perfecting the integrated system of "airborne firefighting + rapid ground support." This transforms heavy helicopter aerial firefighting from a "high-cost demonstration" into a "city-affordable, city-wide coverage" public safety infrastructure capability, possessing extremely strong social promotion value and application prospects.

Combined with the pre-installation and pre-attachment of aerial fire-fighting combination and aerial basket, improve the efficiency of aerial fire-fighting response and give full play to the combat effectiveness of unit fire-fighting units. 2. Significantly reduces energy consumption and operating costs. The overall system purchase cost is low, and the total annual operating cost is controlled within 58,000 yuan, which is more than 93% lower than the traditional ground support mode. At the same time, energy consumption is further reduced through energy-saving methods such as solar heating and external insulation structure. The self-backup power supply ensures stable power supply and avoids the impact of mains power outages on the support effect. Moreover, no additional purchase costs are required, avoiding the wear and tear caused by long-term operation of the engine and APU, and extending the service life of the equipment. 3.

Achieve 24-hour long-term standby: Through fully automatic status monitoring and pre-installed long-term standby, monitor the loading status of the aerial firefighting combination and the aerial basket in real time. The loading detection module is linked with the monitoring unit to ensure takeoff safety, improve system reliability, and reduce maintenance workload. 5. Low purchase cost, strong adaptability, and convenient deployment. It can be adapted to various heavy helicopters and different support scenarios. At the same time, it closely collaborates with the patents already applied for to improve the integrated aviation fire protection system. It supports stable operation in environments ranging from -40℃ to +55℃. The modular design enables rapid deployment and has the value of promotion across all regions, thus promoting the popularization and application of aviation fire protection. 6. The system cost is determined based on the number of fire extinguishing units in the on-duty unit, further optimizing the cost structure, enhancing the low-cost advantage, and ensuring that the city's finances can afford it and that it can operate sustainably in the long term.
