ROTOR BLADE OF ROTOR CRAFT, ITS CONTROL METHOD, AND CONTROL METHOD OF BVI NOISE REDUCER FOR ROTOR CRAFT |
摘要 |
PROBLEM TO BE SOLVED: To sufficiently reduce BVI(Blade-Vortex Interaction) noise generated in landing, improve aerodynamic characteristics in advancing flight, and suppress energy consumption during the flight in a rotor craft. SOLUTION: A movable small blade 12 capable of varying a mount angle for every azimuth by a mount angle variable mechanism is provided in the front side of the end of a base blade 11 having its base end mounted to a rotor head of a rotation drive part. The mount angleθof the movable small blade is set to approximately 0 deg. in the adjacent to an azimuth angle 180 deg. and approximately -5 deg. in the adjacent to an azimuth angle 0 deg.. In a BVI noise reducer, a compressed air is jetted out in the range of the azimuth angle approximately from 135 deg. to 225 deg..
