About this technology
Overview
Rotorcraft typically operate near the ground throughout the duration of the operation. For this reason, military rotorcraft are vulnerable to acoustic detection and public acceptance of civil rotorcraft is limited by annoyance caused by rotor noise radiation. The purpose of this device is to inform the rotorcraft operator of the acoustic impact of rotor noise radiation so that the flight condition of the vehicle can be changed to reduce and/or redirect rotor noise away from noise sensitive areas.
