Blade Vortex Interaction Noise Reduction Techniques For A Rotorcraft

US Patent:
5711651, Jan 27, 1998
Filed:
Jun 13, 1996
Appl. No.:
8/662601
Inventors:
Bruce D. Charles - Mesa AZ
Ahmed A. Hassan - Mesa AZ
Hormoz Tadghighi - Gilbert AZ
Ram D. JanakiRam - Mesa AZ
Lakshmi N. Sankar - Atlanta GA
Assignee:
McDonnell Douglas Helicopter Company - Mesa AZ
International Classification:
F01D 500
US Classification:
416 24
Abstract:
An active control device for reducing blade-vortex interactions (BVI) noise generated by a rotorcraft, such as a helicopter, comprises a trailing edge flap located near the tip of each of the rotorcraft's rotor blades. The flap may be actuated in any conventional way, and is scheduled to be actuated to a deflected position during rotation of the rotor blade through predetermined regions of the rotor azimuth, and is further scheduled to be actuated to a retracted position through the remaining regions of the rotor azimuth. Through the careful azimuth-dependent deployment and retraction of the flap over the rotor disk, blade tip vortices which are the primary source for BVI noise are (a) made weaker and (b) pushed farther away from the rotor disk (that is, larger blade-vortex separation distances are achieved).
