Nanjing Yuefei Technology Co., Ltd.

Company overview

Nanjing Yuefei Technology Co., Ltd. is based in Jiangsu, China, and develops drones and mission systems that combine artificial intelligence with flight control. Its range includes emergency and logistics aircraft, firefighting drones, heavy-lift firefighting models, mission payloads, tethered systems, cloud management platforms and AI image recognition technology. The company undertakes technology development and complete aircraft manufacturing, offering customized solutions for emergency safety and low-altitude logistics. Its work encompasses coordinated drone operations, real-time data transmission, intelligent analysis and dispatching for firefighting, oil and gas inspection, and cargo delivery.

The Lingyun U15 is designed for emergency supply delivery, high-rise firefighting and forest fire prevention. It combines an AI-powered autonomous dropping system with dual-radar obstacle avoidance, terrain-following flight and vision-based precision landing. Its intended operating environments include darkness, rain, fog and mountainous terrain. Tethered power supports 24-hour continuous flight, allowing the aircraft to provide lighting and emergency communications support. Measuring 1050 × 1030 × 540 mm, the U15 uses carbon fiber, aviation aluminum and nylon in its construction.

The HW60 is a compact UAV-mounted laser methane detector that supports integration with the Lingyun U15 and other drone platforms. Using TDLAS technology, it provides non-contact methane detection at distances up to 180 m during the day and 400 m at night. Its measurement range is 0–99999 ppm·m, with sensitivity of ≤5 ppm·m and a 25 ms response time. A 1200 m laser rangefinder supports calculation of leak locations in three dimensions, while a three-axis stabilized gimbal and sweeping mode provide a 3–10 m scanning swath. App and web interfaces display concentration data and leak locations in real time and generate reports with location information for gas pipeline, gas facility and petrochemical inspections.
