Self-propelled dropsonde system

Abstract

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.

Description

technical field [0001] The invention relates to a meteorological monitoring system, in particular to a self-propelled drop-drop sounding system. Background technique [0002] There are new technologies emerging in the field of meteorological monitoring, such as: Chinese Patent Application No. 99103819.3 "with automatic navigation and automatic driving functions, can detect data to the ground according to the predetermined track for processing, high measurement accuracy, and strong flexibility" by " A miniature unmanned aircraft sounding system composed of a miniature unmanned aircraft, a digital radiosonde and a ground receiving control processing system; Chinese patent number ZL 200410070186.4 provides "including fuselage, wings, power drive and control system" And the flight altitude of "airborne radiosonde built in the outer end of the wing" is more than 4km, which is used to "solve the problem of expensive manned aircraft rental and high operating costs of artificial wea...

AI Technical Summary

Problems solved by technology

Traditional drop sounding system: low cost performance, high cost of use, and uneconomical; it cannot obtain real-time and accurate data on temperature, humidity, and air pressure in the vertical profile of the atmosphere at a height above 4km, resulting in vacant records of the upper atmosphere, affecting weather forecasts and Accurate use and service of data; its use is expensive and wastes money
