辽河油田氢能源无人机首飞

Core Viewpoint - The introduction of hydrogen-powered drones by China National Petroleum Corporation's Liaohe Oilfield enhances pipeline inspection efficiency and overcomes previous limitations in drone endurance and performance in extreme weather conditions [1] Group 1: Technological Advancements - The hydrogen-powered drone completed its first test flight with stable flight conditions and smooth data transmission [1] - The drone's hydrogen fuel cell system has doubled its endurance, allowing for a flight time of up to 90 minutes compared to the previous 30-40 minutes with lithium batteries [1] - The drone can operate in a wide temperature range from -20°C to 50°C, ensuring stable performance in extreme weather [1] Group 2: Operational Efficiency - The drone supports a quick switch between lithium and hydrogen power systems within 10 minutes, facilitating efficient operations [1] - Refueling with hydrogen takes only 5 minutes, enabling a "refuel and fly" operational model [1] - The drone can cover a distance of 20 kilometers in a single flight, significantly improving the inspection range from the previous 6 kilometers [1]
