Abstract

The need for silent helicopters has already manifested itself in the civilian and military fields. Helicopters with a reduced auditory signature would give the helicopter tactical advantages in an engagement and hopefully give it the ‘edge’ allowing it to carry out its duties effectively. The main objective of this paper is to determine what technologies can be incorporated onto new helicopters in order to reduce the amount of noise they produce.
