Helicopter Unmanned Aerial Vehicle (HUAV) is recently used in agriculture due to its dynamic, flexible, vertically take-off/landing, hover and laterally fly. The HUAV was researched designed with purpose of greatly reducing manpower, limited direct contact human toxic substances, time working parallel improving quality yield. This paper focused on the main rotor blades 15 kg useful load. first then numerically validated by using computational fluid dynamic (CFD) tool ANSYS software. aerodynamics characteristics such as pressure, velocity, thrust, drag ...were carried out at hovering flight mode. Finally, strengthen analysis were checked solid (CSD) aim this check whether durable enough or not continue next design steps.
