Abstract

Unmanned Aerial Vehicle modelling has found diverse utilities in both civil and military applications. In order to develop an accurate model of their flight dynamics, it is important to properly estimate their aerodynamics coefficients. For this purpose, several methods are usually applied. This paper presents a methodology to obtain the flight dynamics of an Unmanned Aerial Vehicle, for which its aerodynamics coefficients were found based on its geometrical properties. This methodology was applied to the UAS-S4, designed and manufactured by Hydra Technologies, using DATCOM and TORNADO codes. The aerodynamic model thus found was compared with another model obtained by use of ANSYS Fluent software. The model was completed with a propulsion system developed by use of Javaprop. Results have shown that the obtained model is capable of estimating with accuracy the aerodynamic behaviour of the UAS-S4.
