Project Number: 038
Category: Noise, Operations
The objective of this project is to utilize computational and analytical modeling to develop noise abatement procedures for various helicopters for various phases of flight. An extension of the project also includes predictions to support flight test planning. The research team explore representative helicopters to use in computing noise abatement procedures. The helicopters will be selected to determine if it is feasible to develop noise abatement procedures for various categories of helicopters, (i.e., 2 blade light, 4 blade light, 2 blade medium, etc.) or if aircraft specific design considerations will be required in the development of noise abatement procedures.
