Abstract. This paper presents a study of the variable camber morphing wing parameters influence on aerodynamic performance. A comparison of traditional plain flaps and slats (nose flaps) with variable camber morphing wing elements was performed. Numerical simulations were conducted using the XFLR5 software suite implementing XFOIL algorithms. The analysis was performed for a wide range of configurations and conditions, including variations in the rotation axis (hinge) position of the high-lift devices along the wing chord, and a broad range of deployment and angle-of-attack values. The key factors influencing the effectiveness of morphing high-lift devices have been identified.

Keywords: aerodynamics, morphing wing, plain flap, nose flap, high-lift devices.
