Design, optimization, and building flight model of an operational unmanned helicopter

In this paper, a full applicable procedure for design, optimization and manufacturing of an operational unmanned helicopter with deep and detailed research basis is presented. The proposed process deals with challenging aspects of manufacturing of the mentioned type of aircraft such as cost, weight, operation ability, reliability, mission justification, stability, performance, etc. To show the applicability of the proposed procedure, a realization of the process in production of an operational unmanned helicopter named as Parvan is described in this paper. Indeed, Parvan is a Remotely Piloted Helicopter (RPH) with 9 kilograms takeoff weight, and main rotor diameter of 1.54 meters which can lift up a 2 kilograms payload and fly in 120 kilometer radius of action for about 1.5 hours.
