Henan has taken a crucial step forward in tackling a global challenge: high-rise building firefighting.

On July 21, a large emergency rescue unmanned helicopter, independently developed by Henan Sanhe Aviation Industry Co., Ltd. located in the Zhengzhou National General Aviation Demonstration Zone, took to the skies. At an altitude of 180 meters, equipped with a 50mm fire hose, it successfully conducted a fire suppression test on a super high-rise building. A high-pressure water jet accurately penetrated a simulated fire point window, effectively eliminating the blind spot for aerial firefighting operations in buildings over 100 meters tall.

Extinguishing fires in high-rise structures is a decades-old global problem that has perplexed firefighting communities worldwide. Once a blaze ignites in a building exceeding 100 meters, conventional methods are often ineffective. Traditional ladder trucks typically operate below 100 meters, making them inadequate for skyscrapers that are often 200 to 300 meters tall. Firefighting helicopters face limitations due to urban airspace restrictions and the challenges of maintaining precise hover, hindering their widespread deployment.

The key to solving this problem lies in developing new equipment that can "fly high," "remain stable," and "spray accurately." The recent test by Henan Sanhe Aviation Industry Co., Ltd. represents a concentrated effort to overcome these three major hurdles.

Overcoming the "Fly High" Challenge

The S1000 unmanned helicopter used in the test has a maximum payload of 500 kilograms and possesses excellent vertical take-off, landing, and high-altitude maneuverability. Ascending smoothly from the ground to 180 meters and positioning itself accurately, the drone's flight control system demonstrated its responsiveness and wind resistance under realistic conditions.

Overcoming the "Remain Stable" Challenge

For high-altitude operations, hover precision is critical for effective firefighting. At 180 meters, the drone must maintain centimeter-level positioning amidst wind disturbances while countering the powerful recoil generated by the high-pressure water cannon. On-site measurements confirmed that the equipment's hover stability and attitude maintenance capabilities met design standards, with the entire flight platform operating smoothly and reliably.

Overcoming the "Spray Accurately" Challenge

The high-pressure fire water supply system, independently developed by Henan Sanhe Aviation Industry Co., Ltd., uses ground pipelines to provide a continuous water supply. This system stably delivers water flow to the 180-meter altitude for precise downward喷射, directly targeting high-rise fire windows to achieve fire suppression, cooling, and smoke extraction. Both water supply pressure and jet range met design specifications, demonstrating seamless coordination between the aerial firefighting system and the ground-based water supply保障体系.

It is understood that Henan Sanhe Aviation Industry Co., Ltd., the company undertaking this攻坚任务, is a key "chain leader" enterprise in the drone industry, cultivated within the Zhengzhou National General Aviation Demonstration Zone. Since establishing itself in the Shangjie District in 2015, the company has dedicated a decade to deep cultivation in the field, now ranking among the top tier of domestic producers of heavy-lift industrial drones. Currently, drones developed by Sanhe Aviation hold over an 80% market share within China's national firefighting system.

The S1000 unmanned helicopter had already garnered significant attention at various major exhibitions. The success of this practical test marks a critical step for this equipment in transitioning from a "showpiece明星" to a "practical尖兵."

The smooth progress of this test was made possible by the full-chain support from the Shangjie District Fire and Rescue Bureau. During the preparation phase, the fire department, based on the layout of high-rise buildings in its jurisdiction, provided professional input on flight paths and喷射 points. It also coordinated ground water sources and完善ed emergency保障 plans. The深度介入 of firefighting forces ensured the test was truly "derived from实战 and applied to实战."

"In high-rise firefighting, a minute error can lead to a巨大损失; precision is the paramount lifeline," said Chen Weiwei, Vice General Manager of Henan Sanhe Aviation Industry Co., Ltd. He stated that the toughest "hard bone" during the攻坚 process was maintaining water pressure stability and countering反作用力 while in a high-altitude hover. "The professional guidance from the fire department helped us optimize the technical方案 closely aligned with practical needs."

Chen Weiwei介绍 that the下一步 will involve using the test data to further enhance system stability and operational convenience, accelerating the integration of this装备 into existing urban firefighting systems. The goal is to deploy this technology to the frontline of high-rise building火灾防控 as soon as possible.

In the field of aviation emergency rescue, the Zhengzhou National General Aviation Demonstration Zone has successively conducted a series of verifications, including multi-aircraft实战演练s and C909 medical aircraft air transport trials, continuously exploring new models for "air-ground integrated"救援. Drone enterprises from Henan, represented by Sanhe Aviation, are accelerating their shift from "following" to "running alongside" and even "leading," serving as a vivid illustration of Henan's efforts to seize opportunities in the new赛道 of the low-altitude economy.

The low-altitude economy is an important direction for cultivating new quality productive forces, and aviation emergency rescue is one of its most socially beneficial application scenarios. The success of this攻坚 not only addresses the height limitations of ground-based firefighting equipment but also validates Henan's core capabilities in the research, development, and manufacturing of high-end equipment for large unmanned helicopters.

As cities grow skyward, fire safety must ascend in tandem. What喷射 down from 180 meters is not merely a column of water; it is a resolute determination by Henan to lead industrial innovation through technological innovation. In this攻坚, Henan has found a "world-class answer" to a "world-class problem"—transforming the "impossible" into the "possible" with the perseverance of a decade-long effort.

As more innovative entities like Sanhe Aviation continue to grow and thrive across the Central Plains, Henan is accelerating its transformation from the "Central Inland" to an "Aerial高地," contributing more of its strength to the national development of comprehensive safety and emergency response systems.
