RESUMO
The Unmanned Aerial Vehicles (UAV s) have a variety of applications, wether monitoring of forest fires, power lines, traffic, crowds, but also can be used for aerial target military applications. Even though it is still somewhat restrict to civil application because of lack of regulation, such vehicles are being developed and studied in the academic sphere. The particularity of this work is the development of an Unmanned Aerial Vehicle for use in aerial spraying to reduce the risks of manned agricultural operation. Thus, It is presented the methodology used to determine the thrust to weight ratio and wing loading, and geometric characteristics of the UAV. Analytical calculus of aerodynamic and vehicle performance are made, and in the step aerodynamic design is made the optimization of the airfoil NACA 4415 and calculated the aerodynamic parameters of the whole vehicle. Moreover, being unmanned, it is made the selection of the Flight Control System to attend mission requirements. Technical standards for approval are used to design calculations as the RBHA (Brazilian Requirements for Approval of Aircraft) wich refer to the main international standards: FAR (Federal Aviation Regulation) of United States of America, and JAR (Joint Airworthiness Regulation).Whereas is used in the spraying of pesticides, it is presented the technology of application used in manned aircraft, and the choice of the spray system for vehicle
