| Abstract: | High-altitude long-endurance UAV is a new unmanned aerial vehicle. In battlefield reconnais- sance and high-altitude atmospheric sounding and so on has its special uses. According to the characteristic of UAV, joined-wing aerodynamic configuration is constructed. Through modeling, meshing, numerical calculation and Matlab software simulation, vortex lattice method is applied to analyze the UAV lift-drag characteristics, longitudinal static stability and lateral and directional static stability. The calculation resuits fulfill design objectives and which can provide theoretical basis for large-scale UAV conceptual and oreliminarv design. |
