| Abstract: |
| In this paper, the lift and endurance of the world’s representative long-endurance UAV were sorted out and summarized, and two typical aircraft were briefly introduced. Based on the standard atmospheric model, neglecting the influence of regional, diurnal, seasonal fluctuations and latitude, and taking altitude as a variable, the calculation methods of three environmental parameters, namely temperature, air pressure and solar radiation, were sorted out. Five areas covering coast, plateau, desert, plain and other topographic features, as well as different altitudes, have been selected in china. The atmospheric environment and solar radiation in these five regions were investigated to obtain representative surface-altitude environmental characteristics. The date on temperature, humidity and radiation at different heights in these five regions were analyzed. The environmental parameters show obvious periodicity and regional differences. |
