Haery Power DB442 debuted at the 2025 Low-altitude Economic Development Conference

On September 5, 2025, the 2025 Low-altitude Economic Development Conference with the theme of "Scene Innovation Leads Safe and Orderly Development" opened in Wuhu, Anhui. As the first special event of the 2025 World Manufacturing Conference, this conference focuses on low-altitude economic policies and new industrial needs, and through multi-dimensional activities such as "Convention, Exhibition and Performance Guide", it focuses on displaying cutting-edge achievements, landmark products and typical application scenarios in the domestic low-altitude economic field.

Haery Power and its subsidiariesFour celebrity products, GB409, DB410, DB416, and DB442, were unveiled at the exhibition. Among them, the "Menghuang" DB442 300kW class heavy oil aircraft engine independently developed by the company has become the focus of the audience with its hard-core technical strength. The successful installation of the engine not only marks a major technological breakthrough in the 300kW level field of the domestic heavy oil power, but also means that this key power has officially entered a new stage of stable, reliable, independent and controllable batch application, and large-scale productization.

It is worth noting that the previous Haery PowerThe "Skylark" DB416 120kW class heavy oil aviation engine has been mass-applied. The launch of the "Mengdiao" DB442 is another major achievement of the company on the same technology platform, fully demonstrating its continuous improvement in the field of heavy oil aviation power and its strong independent innovation capabilities.

The "Mengdiao" DB442 engine shows excellent platform adaptability and can currently quickly match 3-5-ton fixed-wing drones and 1.5-3-ton unmanned helicopters, providing stable and trustworthy power support for different types of medium and large unmanned equipment. Looking to the future, the engine also has the potential to expand to a larger take-off weight multi-engine platform, which will further broaden the application boundaries of domestic heavy oil aerospace power and lay a core power foundation for the research and development and application of more heavyweight unmanned equipment.

Cooperative application cases in the park

Relying on the collaborative cooperation between enterprises in the park, China Electronics Technology AircraftThe large-scale drone of the "Xiangyun V" is equipped with the "Mengdiao" DB442 heavy-oil aircraft engine, which made its first public debut, becoming one of the highlights of the exhibition. As a 5-ton dual-engine heavy oil logistics drone, the "Xiangyun V" has outstanding performance advantages: it not only has a large load of 2,000 kg and a large range of 2,000 kilometers, but also has a spacious cargo hold of 14.5 cubic meters and supports air delivery function, which can quickly match the needs of diversified aviation logistics scenarios.

What is particularly critical is that this model has achieved multi-faceted domesticization and independent control of core technologies. It has got rid of external dependence from the power system to the entire machine design. It can not only serve conventional aviation logistics transportation quickly, but also play a key role in special scenarios such as emergency rescue and support, providing strong support for the industrial application of domestic large-scale logistics drones.
