To provide: a contactless acoustic survey system which, when irradiating a measurement object with a sound wave from an acoustic emission source mounted to an unmanned aerial vehicle, reduces the noise propagating to the measurement object; and an unmanned aerial vehicle that is used in this system.SOLUTION: Provided is a contactless acoustic survey system for irradiating a sound wave downward from an acoustic emission source mounted to an unmanned aerial vehicle after the unmanned aerial vehicle flies and lands at a measurement position so as to vibrate the measurement position, and analyzing the result of measurement of the vibration speed of the vibrated measurement position, thus surveying the measurement position. The unmanned aerial vehicle comprises: an acoustic emission source, a leg part that is ground on a measurement position in a landed state; and a vibration cutoff mechanism provided on a path through which a vibration generated to the acoustic emission source when the acoustic emission source irradiates a sound wave, is propagated to the measurement position via the leg part, the mechanism cutting off the propagation of the vibration.SELECTED DRAWING: Figure 5

    【課題】無人航空機に搭載された音響発信源から音波を測定対象に照射する際に、測定対象に伝播するノイズを低減させる非接触音響探査システム及びそのシステムに用いられる無人航空機を提供する。【解決手段】無人航空機が飛行して測定位置に着陸した後に、無人航空機に搭載された音響発信源から下方に音波を照射して測定位置を加振し、加振した測定位置の振動速度を測定した結果を解析して、測定位置を探査する非接触音響探査システムであって、無人航空機は、音響発信源と、着陸した状態において測定位置に接地する脚部と、音響発信源が音波を照射する際に音響発信源に発生する振動が脚部を介して測定位置に伝播する経路に設けられ、当該振動の伝播を遮断する振動遮断機構と、を備える。【選択図】図5
