Reduction of Rotor Noise Using Serrated Blades with Modulated Airfoil Thickness
Proceedings of the Vertical Flight Society 82nd Annual Forum and Technology DisplayPrevious computational aeroacoustics studies of a hovering ideally twisted rotor demonstrated the presence of new broadband noise sources, trailing-edge vortex shedding (TE-VS) noise and blade secondary vortex interaction (BSVI) noise, yielding high-frequency and mid-frequency noise respectively.

Wake control of aeroengine blade based on matching design of the non-uniform serrations
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace EngineeringDue to the design requirements of higher efficiency and pressure ratio, and the characteristics of transonic velocity and bending-torsional profile, the problem of wake disturbance has become increasingly prominent on aeroengine blade. Traditional aerodynamic design makes it difficult to achieve the ideal control of blade wakes.

[Similar skin lesions in victim and perpetrator caused by a knife with a serrated blade].
Archiv fur Kriminologie, 2000Reported in this paper is an attack of two adolescents on a man who was killed in the fight, with several kitchen knives being used, including two with grooved and wave-grooved blades. One of the offenders held the victim tight from behind and was injured by his attacking accomplice++.
