CFD analysis on the effect of winglet cant angle on aerodynamics of ONERA M6 wing
Winglets are one of important part of the wing that can reduce the vortex formed at the wing tips and therefore reduce induced drag by partial recovery of the tip vortex energy. Moreover, they increase the effective aspect ratio without actually increasing the wingspan. The geometry of the wingle...

| Summary: | Winglets are one of important part of the wing that can reduce the vortex formed at
the wing tips and therefore reduce induced drag by partial recovery of the tip vortex
energy. Moreover, they increase the effective aspect ratio without actually increasing
the wingspan. The geometry of the winglets plays an important role in their task. In the
present research, computation of lift and drag of ONERA M6 wing have been
conducted using ANSYS Fluent. The results have been validated with the NASA results.
Flow features of the entire wing including winglet were examined at different cant
angles of winglets of 30°, 60° and 75° at different angles of attack from 3° to 6°. It is
observed that among the cases of this study, wings with winglets produces higher CL/CD
ratio than the normal aircraft wing without winglets up to certain degree of angle of
attack and by further increasing to higher angle of attack its performance getting
diminished. The investigated concept of adaptable angle winglets appears to be a likely
substitute for refining the aerodynamic effectiveness of an aircraft. |
