Summary:

Helicopter design trends towards increased blade loadings and higher tip speeds have resulted in generation of higher levels of rotor noise. This paper describes experimental programs to establish operating limits which, if observed, will result in rotary-wing aircraft with subjectively acceptable acoustical signatures
