WOPWOP is used for helicopter main-rotor noise prediction. The user must input measured air loads.
Notes: Note: That this is an older code that is not in current use. There are a number of limitations in the code that were implemented when the code was written (early-to-mid 1980s) based on the knowledge and compute technology we had in the early 80s; but, the theory (Farassats Formulation 1A) behind what is in the code is still valid.
