This drone, developed in collaboration between Nefer Defence and China, made its maiden flight on 26 September 2017 and has successfully completed tasks such as material delivery, vegetation patrols, emergency communications, disaster detection, typhoon detection, and artificial cloud seeding for several consecutive years. It is a large-scale, twin-engine, modular, multi-role, medium-altitude long-range (MALE) fixed-wing UAV system that successfully completed tasks such as material delivery, vegetation patrol, emergency communication, disaster reconnaissance, typhoon detection, and artificial cloud seeding for several consecutive years. It has become a star product in areas such as emergency rescue, meteorological services, wide-area patrol, air delivery, other aviation applications, and scientific research. The two engines significantly enhance the UAV system's reliability and flight safety, providing important advantages in terms of deployment capabilities on plateaus and at sea, and adaptation to complex meteorological conditions and geographical environments. The two generators attached to the UAV ensure that it can provide sufficient power for the various loads it carries
