ADOCHA · Acoustic Design Of High-lift Architectures

Regulation of the sound production of aircraft is becoming stricter, in part due to an increase in the noise generated due to the rising numbers and size of aircraft. As a result identification and reduction of the major sources of sound, particularly in the take-off and landing phases when the aircraft is close to population centres, is paramount. High lift devices, particularly during the landing phase, are a major source of airframe noise. As a result there is a requirement for a tool to allow the acoustic properties of a high-lift configuration to be determined buring the design process. The purpose of this proposal is the development of such a tool.
