8moon11dayIn the morning, Haery Power independently developed"Big Eagle"DB442Type300kWThe first large unmanned transport aircraft of Sichuan Tengdun Technology Co., Ltd. in the country's first large unmanned transport aircraft was successfully completed at Zigong Base.

This type of unmanned transport wingspan16.1Rice,4.6Rice, have12cubic meters of loading space,2Ton-level commercial load capacity is a large, nationally produced large dual-engine unmanned transport aircraft currently being developed in accordance with market demand in China.。

The successful flight of this aircraft has a profound impact.From the perspective of the aircraft,This first flight was successful. This marks a new breakthrough in my country's low-altitude economy to achieve greater self-reliance and self-improvement in large unmanned transport aircraft. It also supplements the gap in my country's large-tonnage unmanned transport aircraft, opening a new chapter in my country's air transportation field.In terms of engine,This is the“lark”Another platform product application after batch application of heavy oil aircraft engines. This not only demonstrates Haery Power's deep technical accumulation and continuous innovation capabilities in the field of heavy fuel aero engine research and development, but also reflects its firm determination and excellent contribution in promoting the development of my country's aerodynamic technology.

2024Year is called the first year of low-altitude economy.at the same timeWith the Implementation Plan for the Innovation Application of General Aviation Equipment (2024-20302019)》 plan is issued,Haery Power closely grasps national policies and industry trends, focuses on the needs of low-altitude economic industries, and actively explores product application scenarios.

As the leader in domestic small and medium-sized aero engines, Haery Power continues to pay attention to domestic drones, general aviation aircraft andWhomIn response to the urgent needs of the industry, Haery Power insists on independent research and development and strives to provide the industry with superior power products.

now,Equipped"Big Eagle"DB442Heavy oil aircraft engineThe successful first flight of the unmanned transport plane is undoubtedly an exciting and important good news. This means that it will soon achieve stability and performanceControllable and productized batch application has become the successor120kWAnother masterpiece after the mass application of grade heavy oil aviation technology, the outstanding performance of the same platform products once again demonstrates the maturity and innovation of technology.

This engine has a wide range of applications and can be adapted well3 - 5Tons of fixed-wing drones and1.5- 3For tons of unmanned helicopters, the take-off weight of multiple-engine platforms will be greater in the future. In actual customer application process, its advantages are fully revealed. This product not only demonstrates mature and trustworthy performance, but also has extremely low operating costs. From a practical application perspective, it has the following characteristics:

①Independent/Domestic："Mengcheng" heavy oil AV is independently designed by Haery Power.Self-owned property rights，Domestic. It inherited120kWclass“lark”heavy oilApplication features of Aerospace Engine:

②Low cost:Compared with imported heavy oil engines and domestic turbines of the same power level, they have the characteristics of low procurement costs, low maintenance costs and low operating costs after batch volume. They are currently highly competitive in ton-kilometer costs in large-tonnage transport aircraft, and are especially suitable for commercial applications of low-altitude economy for civilians.

③Altitude performance:Single-stage supercharged version5000mpowerNon-attenuation, secondary supercharged version6000mPower does not decay,Supports higher altitude than original take-off and lower, reaching extreme altitude12000m. It can cover all plains' application scenarios.

④More-effect ratio:Takeoff power300-320kW, can support1.5-3tonclass helicopter,3.0-5Tons of fixed wing power demand.

⑤Wide-area environment application:-40°~+70°Stable power output can be achieved in various environments. useThe platform-based fully authorized electronic control system can sense changes in the external environment in real time and adaptively adjust the stable power output.

⑥Heavy oil products:Use heavy oil products to meet the needs of civilian and military oil products. It has the characteristics of normalization of oil products, convenient guarantee, long-term storage and good use safety.

The future "Big Eagle"DB442Heavy oil aviation engines will continue to promote the application process of large-tonnage, low-cost and commercialization of fixed-wing, helicopters, ground-effect wing vessels and other aircraft, injecting unprecedented powerful impetus into the development of the industry. This will achieve a more level of breakthrough, thus achieving the goal of flying more, flying farther and becoming smarter. Really achieve "making motivation easier".
