ヘリコプタ騒音のひとつであるBVI(Blade Vortex Interaction)騒音低減化技術確立のための基礎データ取得を目的とし、航技研大型低速風洞を用い翼端渦干渉下におけるフラップ動作時の翼面上圧力分布計測、翼端渦計測およびLLS(Laser Light Sheet)による可視化を行った。本報告では、風洞試験の概要とその結果の一部を紹介する。
The BVI (Blade Vortex Interaction) is one of the serious helicopter noises. In order to obtain the basic data for establishing the BVI noise reduction technology, measurements of the pressure distribution on the wings and the vortices around the wing tips as well as the visualization of vortices by LLS (Laser Light Sheet) were carried out at the NAL Large Low-speed Wind Tunnel when the flap worked actively under the BVI condition. This paper presents the outline of the wind tunnel test and a part of the results.
