Recently, significant progresses have been made in dynamically actuated leading-edge (LE) and trailing-edge (TE) aerofoil technologies individually. However, a gap remains in the dynamically coupled LE-TE morphing motion. This study aims to build on existing knowledge by combining these two separate motions to investigate further potential aerodynamic improvements and noise mitigation. First, numerical predictions of the baseline case are compared with experimental results for validation. Then, adopting the mathematical formulation proposed, a harmonic function is introduced to enable independent control of morphing amplitude and frequency for the LE and TE sections.
