A optimization procedure for identifying quiet rotorcraft |
|
approach trajectories is proposed and demonstrated. The |
|
procedure employs a multi-objective genetic algorithm in |
|
order to reduce noise and create approach paths that will |
|
be acceptable to pilots and passengers. The concept is |
|
demonstrated by application to two different helicopters. |
|
The optimized paths are compared with one another and to |
|
a standard 6-deg approach path. The two demonstration |
|
cases validate the optimization procedure but highlight |
|
the need for improved noise prediction techniques and for |
|
additional rotorcraft acoustic data sets. |
