Aerodynamic and stability analysis of the Safat01 aircraft

Abstract

This paper aimed to predict aerodynamic & stability data for the Safat01 aircraft. Because of its economic and time efficiency, the Digital DATCOM program has been used to predict the stability and control derivatives for the subsonic, low angle of attack (less than 15 degrees) flight regimes. The DATCOM aerodynamic results were very close when compared to CFD. The effect of the nominal centre of the gravity position was considered. According to the computed stability results, the aircraft has been found statically stable and possessing longitudinal dynamic stability. This agrees with the flight tests results conducted on the aircraft which showed stable behaviour.
