Our main concept of doing it is savings of the compuational cost by maintaing all aerodynamic and propulsive parameters. The modern unmanned aerial vehicles has been designed and simulated for its thrust capacity and endurance analysis. The real time analysis has been done using sliding mesh and multiple reference frames (MRF) techniques. However, the magnitude of thrust differed with 15% at any simulated positions. Due to this tilt or deviation may be a interesting options to lower the computational cost of MRF’s with sliding mesh.
In this research, the several numbers of CFD simulations has been performed for establishing the computational methods with high accuracy for the flow generated by the rotation and forward motion of the UAV: MRF and sliding meshes. This study has been done by considering the ground effects. Despite, the outcomes of the present research denote for the future works, the extension of this analysis to other MUAV, UAV and RUAV models with different characteristics such as the design of the aerodynamic body, installation of number of propellers, the blade designed & its selections, or proper placing of the rotors for its aerodynamic balance and ease to control, etc.
