A self-propelled dropsonde system comprises an unmanned aerial vehicle on which a propeller motor, an airborne flight control system and a sonde. A hydrogen storage system is arranged at the interior front part of an unmanned aerial vehicle body; an environment control cabin with a fuel cell is mounted at the middle part of the unmanned aerial vehicle body; and the airborne flight control system is arranged at the rear part of the unmanned aerial vehicle body. The self-propelled dropsonde system provided by the invention is advantaged in that an optimal weight ratio of about 1/10 between a dropsonde and an aircraft and the ceiling is high. As the fuel cell is used as unmanned aerial vehicle energy, the flight time is long. Through an air collecting chamber and a supercharger, the air is heated and pressurized by the unmanned aerial vehicle; and the air inlet temperature and the air density of the environment control cabin are adjusted; therefore, the working performance of the fuel cell at high altitude is improved and enough power for guaranteeing cruising duration is provided to the unmanned aerial vehicle. As a plurality of sondes are mounted on the self-propelled dropsonde system, meteorological data of the atmosphere vertical section can be accurately detected from the plurality of dropsondes at altitudes of 12-20 km in once launching. The self-propelled dropsonde system provided by the invention is advantaged in that the system is economic and environment-friendly and the cost performance of the system is higher.
