ACOUSTICAL COMPARISON OF CONVENTIONAL TAXIING AND DISPATCH TOWING – TAXIBOT′S CONTRIBUTION TO GROUND NOISE ABATEMENT

摘要

Beside noise of airborne aircraft as a primary noise source at airports, ground operations, such as taxiing, have contributing and nonnegligible impacts on airport noise levels. To address this issue amid growing environmental awareness, the deployment of electromobility at airports is planned to be extended. One such electrical mobility device is a dispatch towing vehicle called TaxiBot, which was first tested at Frankfurt International Airport in 2014. This paper aims to quantify noise reductions of dispatch-towed aircraft in comparison with conventional taxiing operations. It derives a new measurement method from existing and comparable standards, describes the measurement procedure, and presents the results. Finally, a conclusion and outlook is given.
