"Cross Twin Rotors" + "Heavy Oil Aviation Engine", this combination allows CNOOC to undergo excellent acceptance!

May 18, 2025, equippedHaery Power DB416 Heavy Oil Aviation EngineofQinghai EquipmentThe JZ-550 unmanned helicopter officially passed the factory acceptance of CNOOC Energy Development Co., Ltd., becoming the first unmanned helicopter in China to enter the "three barrels of oil" (CNOOC, Sinopec, and CNOOC) system.

The JZ-550 unmanned helicopter is a new generation product independently developed by Qinghang Equipment Company. It adopts a cross-double rotor design and is equipped withHaery PowerDB416 heavy oil aircraft engine. Large takeoff weight 675kg, large payload reaches250 kg, larger ceiling 7500 meters, longer flight time can reach 5 hours. at the same timeHave relatively load-to-load ratio, more stability, more wind resistance, more hover time, more original, more sea-friendly6 major features and advantages, can be equipped with a variety of task modules such as photoelectric pods, strong sound and optical pods, hanging and throwing loads, fire extinguishing devices and ground storage and transportation cabins.

DB416 heavy oil aircraft engineWidely used inThe 700kg-class unmanned helicopter and the 1.6t-class fixed-wing drone are committed to creating a low-cost, standard performance, mature and reliable heavy oil power system. It is used in all scenarios such as emergency rescue, fire fighting, material delivery, geological exploration and public safety, and has the following characteristics:

①Heavy oil machineDuration of flight，Expand the boundaries of the job scenario:

Heavy oil engines have relatively high thermal efficiency and cruising fuel consumption is lower than previous gasoline engines30-40%, the aircraft platform's battery life can be increased by 30-50% at the same fuel volume.The drone is equipped with photoelectric and meteorological sensors for oil and gas exploration and offshoreThe inspection provides real-time data, withThe digital platform of the "three barrels of oil" forms synergy.

② Large payload，Lifting the hanging bucketFire extinguishing capability：

DB416 heavy oil aircraft engine power reaches 127kW, which is 20%-50% higher than the current mainstream 85kW/106kW product, greatly improving the terminal's carrying efficiency. Mounting a large-capacity fire extinguishing bucket can respond quickly in the early stages of fire on the oil and gas platform, avoiding the expansion of losses caused by distance and reaction time of traditional firefighting ships.

③ Heavy oil products:Safe, stable, mature and trustworthy

Heavy oil has high density and high safety, and will not catch fire even if it is splashed in sparks., eliminate the potential for explosions and burning in dangerous areas such as oil and gas fields and refineries from the source. After gasoline leaks, it will quickly volatilize to form a combustible mixture, which can easily cause chain explosions.——This is also one of the core considerations for the "three barrels of oil" to choose heavy oil drones first.

④ Industry substitution: From "bottleneck" to "overtaking" domestic breakthrough

Previously, European and American marine drones mostly used kerosene power, but kerosene costs are relatively limited, and technology blocked China. The breakthrough of domestic heavy oil drones not only realize fuel——Power-the platform is domestically produced in the entire chain, and it highlights its product advantages with the advantages of "low cost + relatively performance" - becoming the core driving force for domestic power + low cost solutions to replace imports.

As a Chinese energy fieldThe procurement of "national team" and "three barrels of oil" is of benchmark significance. It will drive other energy companies, local governments and domestic markets to pay attention to heavy oil drones, and form a chain reaction of domestic equipment instead of imports. In the future, with the explosion of demand in many fields such as energy, logistics, and emergency response, heavy oil power may become the standard configuration for heavy-duty drones.
