News | Top 10 releases! Haery "Big" DB442 engine shines on the World Manufacturing Conference, empowering the application of all scenarios of low-altitude economy

On the morning of September 20, 2025, the World Manufacturing Conference was grandly opened in Hefei. At the opening ceremony, through a four-and-a-half-minute video, Anhui showed the world ten finest industrial products that can be used as golden signs of "Made in Anhui". Independently developed by Anhui Haery Aviation Power Equipment Co., Ltd. "Meng Diao" DB442 heavy oil aircraft engineAs an outstanding representative in the field of low-altitude economic power, he has successfully entered the industry with his excellent performance and advanced technologySurrounding"Top Ten Releases",Show the world the innovative achievements and hard-core strength of Anhui's more advanced equipment manufacturing.

one,Advanced support, Anhui Intelligent Manufacturing

The World Manufacturing Conference is an important platform to showcase the innovation achievements of global manufacturing. This timeThe list of "Top Ten New Technologies and New Products" aims to select and display Anhui Province's innovative achievements with advanced domestic and international levels in the manufacturing field, representing the relatively standard of Anhui's manufacturing industry.DB442 engineThe selection marks that its technological advancement, market application prospects and independent control have received strong support from the official and industry. This engine not only represents Haery Power's innovative breakthrough, but also demonstrates Anhui's strong competitiveness in the field of low-altitude economic power equipment.

two,Strong heart, excellent performance

"Mengying" DB442Not the first time he has made his mark. As the first domestic model with all independent intellectual property rights and successfully applied to civil unmanned transport aircraft300kW class aviation heavy oil piston engine, it has long beenCreate multiple achievements, such as August 11, 2024,DB442 engineSichuan Tengdun Technology Co., Ltd. successfully made its first flight in the country's first large unmanned transport aircraft at Zigong Base in Sichuan, realizing the new application of this heavy oil aircraft engine in the low-altitude economic field.

DB442 engineHave relatively high power, low fuel consumption, full-region adaptability and independent controlThe most significant feature of the takeoff power is high300-320kW, excellent power-to-weight ratio; heavy oil products are used to ensure convenient and safe; can adapt to extreme environments from -40°C to +70°C, and can operate stably in a relatively empty and stable manner at an altitude of 12,000 meters, covering various complex application scenarios such as plains, relatively raw areas, mountains, and deserts on multiple sides. The engine has achieved 100% independent property rights, 100% independent control, and 100% domestic production, effectively filling the power system gap in the 300kW power segment, which can be regarded as a major achievement in my country's aviation field.

three,Full-scene application empowers thousands of industries

DB442engineIt has been used in transporting fixed wings, reconnaissance and strike fixed wings, ton-class helicopters, ground-effect wing shipswait7The drone unit covers military delivery, civil transport, speed-based inspection and attack, emergency fire protection, and other fields.DB442 engineThe powerful performance provides strong power support for it in many fields, truly realizing"One core and multiple uses, all-around empowerment."

①Emergency rescue and fire fighting

DB442engineApplied to1.5-1.8tMedium and large unmanned helicopters provide strong power for them, making them have high load and long-term flight capabilities, quickly deliver fire extinguishing agents, perform relatively airborne fire operations, and go deep into dangerous areas to transport materials and transfer wounded personnel to improve emergency response efficiency.

②Material Delivery and Unmanned Logistics

existAt the 2025 Low-altitude Economic Development Conference,DB442 engineChina Electric AircraftThe large-scale drone "Xiangyun V" made its first public debut. This 5-ton dual-engine heavy oil logistics drone has a large load of 2,000 kg and a large range of 2,000 kilometers. It supports air delivery function and can quickly match the needs of diversified aviation logistics scenarios.DB442 engineIt provides core power support for opening up air logistics channels and building a low-altitude smart logistics network.

③Public Safety and Geological Exploration

DB442engineIt has been used in 2-4.5t fixed-wing drones, making them competent for long-term patrol and monitoring, anti-smuggling and drug control, anti-terrorism investigation and other tasks. It can also carry various exploration equipment, and go deep into areas with few people to provide a trusted platform for resource exploration and environmental monitoring.

④Ship-based and special environment applications

Use of ship-based, ground-effect wing ships and other scenariosDB442 engineIt can achieve long-term flight time, low cost, large load, independent control,Unified oil products, can be used in emergency communication/Conductor, island material transportation, island and reef emergency materials and other scenarios are widely used to meet the needs of all-weather and all-scene application.

Four,Independent innovation, drive the future

Haery Power has always insisted on independent research and development，DB442 engineImplemented100% independent and controllable completely breaks the foreign monopoly of the power system in this power segment and fills the domestic gap. Its excellent low cost, relatively reliable and extensive environmental adaptability make the large-scale and commercial application of large-scale unmanned equipment possible, injecting a strong "Chinese heart" into the vigorous development of my country's low-altitude economy.

The spotlight of the World Manufacturing Conference confirms"Brave Eagle" DB442enginehard-core strength and excellent quality. From the successful first flight in Zigong, Sichuan to the glory of Hefei, Anhui, on the list, Haery Power is practicing with solid stepsThe corporate vision of “make motivation simpler”. In the future, Haery Power will continue to deepen its efforts in the field of aerospace power and promoteDB442 engineIn more scenarios, we will provide global customers with more trustworthy and faster power solutions, and contribute Anhui's strength to the new era of low-altitude economy!

Manufacturing in Anhui, attracting attention from the world; Haery Power, driving the future!
