The technology relates to an improved aerofoil body that achieves improved aerodynamic performance by way of incorporating passive fluid-flow control devices. The flow control devices are the combination of vortex generators and tubercles devices. The combination of TLE (Spherical or Sinusoidal) and VG’s has advantages in improving performance in both pre and post characteristics. • TLE and VG combination will reduce noise in case of turbines and propellers. • TLE and VG combination will prevent the damage to the structure due to the bursting of separation bubble
