Abstract
Aiming at the actual demand for noise certification of civil aircraft, the noise certification testing technology of propeller small aircraft and helicopters is mainly studied. Civil aircraft noise certification is mainly carried out in accordance with the provisions of CCAR-36, including two aspects of test system architecture and test flight method design. The qualification criteria in the noise certification test are mainly two points, one is that the noise data meets the restriction requirements of CCAR-36, and the other is that the measured track meets the method requirements of CCAR-36. An equivalent procedure for noise certification of small propeller aircraft is provided, and two specific implementation methods for determining the measured track are provided, which provide some effective references for noise certification of other types of aircraft.
