A computational fluid dynamic acoustic investigation of a tiltwing eVTOL concept aircraft

With the advancement in electric propulsion systems, aircraft designers and manufacturers are no longer constrained to established configurations. Developments Vertical Take-off Landing (VTOL) have been seen recent times through design of modern tiltrotor aircraft, tiltwing concepts multi-rotor designs. The combination these developments allowed engineers propose designs which utilise vertical take-off landing capabilities a with electrically driven deemed eVTOL (Electrically Landing). This investigation aims develop an understanding aeroacoustic emissions associated non-linear interaction resulting from integrated propellers airframe. Acoustics is one key requirements any future certification, hence, was conducted into baseline design, followed by optimisation study aiming reduce amount noise generated.
