This research follows a previous study that consisted in analyzing the aerodynamic performance of an aircraft equipped with adaptive winglets compared to an aircraft equipped with fixed winglets. Based on Reynolds-averaged Navier–Stokes methods, it was observed that adaptive winglets help the CRJ700 to reduce its drag by up to 2.90%. Using these aerodynamic results, this research now involves analyzing the climb and cruise performance benefits achieved by an aircraft equipped with adaptive winglets. The methodology presented in this paper details the aerodynamic and performance models used to obtain these new results. A new methodology for calculating the downwash deflection angle from OpenFoam simulations was also developed. The results show that an adaptive winglet can reduce the fuel flow of an aircraft by up to 1.99% in cruise with respect to an aircraft equipped with a fixed winglet. Interesting benefits were also found for climb segments, such as a climb time reduction of up to 128.11 s.
