Experimental investigation of aerodynamics behavior of a new generic of unmanned air vehicle (heliplane) by Kaddouri Djamel, Benlefki Abdelkrim, Adjlout Lahouari, Mokhtari Abdellah

“…This article aims to present an experimental aerodynamic study of an autonomous surveillance unmanned aerial vehicle (UAV) that is capable of combining the advantages of both categories, namely the fixed-wing drones and the rotary-wing drones. To achieve this objective, a wind tunnel was used to study the flow around this drone in order to better understand the aerodynamic phenomena and to obtain some initial estimates of the lift, drag and moment coefficients, at three different Reynolds numbers of 4.02×104, 6.03×104 and 8.04×104, and for different angles of attack, from [−45°, +45°] with step of 1°.The experimental results obtained in this work show an casi-symetrical variation between the negative and positive incidence angles of the lift coefficient, which indicate that the heliplane can fly in an inverted position, whatever the angle of incidence. …”
