The plan designs new general plan of UAV with the consultant of the plans abroad. Afterwards, with the theory of aircraft design used, the design of the configuration emphasizes on general configuration, general factors, matching engine, weight estimation, the contrast between the thrust loading when taking off and the wing loading, parameters of the surface of the wing design, airfoil selection, rudder surface, landing gear parameters, etc. After designing, the three dimensional emulation of the aircraft configuration will be launched. The software working mainly includes parts design, blueprint painting and three dimensional models. Meanwhile, the plan of the aircraft will be improved and optimized so that a complete plan of UAV design and optimization will be made.
