Abstract

This paper presents the noise level measurements of a thruster unit, consisted of two ducted fans. In a recently developed prototype, two parallel axial flow ducted fans are used to provide the necessary thrust force. The unit can be used for controlling the motion of a balloon based/lifted UAV (unmanned aerial vehicle), which may operate in such environments where the sound emission should be minimized. The aim of the present work is to understand and explain the noise measurement results, to identify the characteristic noise components of the developed thruster unit by using the modal analysis technique of finite element analysis, and based on that, some design considerations are formulated which takes into account the important noise reduction requirement.
