Measurement method for the acoustic evaluation of benefits from innovative dispatch towing technologies at Frankfurt Airport.
[Conference or Workshop Item]

Abstract

New dispatch towing technologies, in particular the pilot-controlled, robotic tractor called TaxiBot, which was first tested at Frankfurt Airport, promise to reduce noise, pollution, and fuel consumption during the taxi-out process of an aircraft. To quantify noise reduction of dispatch-towed aircraft, comparisons with present taxiing and towing operations are needed. For this purpose no standard measurement procedure exists. To derive a practical approach, comparable standards, e.g. for road vehicles, were identified and adapted to given frame conditions and requirements at an airport. On this basis an objective acoustic measurement method was developed facilitating the comparison of different pass-by configurations for aircraft, tractors, and combinations thereof. Furthermore, the measurement method enables an acoustic evaluation between the TaxiBot and conventional tractors while standing with engines running. In addition, requirements for technical equipment and environmental conditions to perform sound measurements at an airport are specified. The approach aims to obtain comparable and reliable measurement results. This, in turn, leads to the creation of a database to assess noise due to aircraft taxi operations and serves as a foundation for noise simulation, calculation, and prediction. The proposed method can establish a new standard for acoustic measurements at airports.
