Preliminary flight demonstration test on airframe noise reduction technology successfully completed
The Japan Aerospace Exploration Agency (JAXA) has successfully completed a preliminary flight demonstration test for the FQUROH project using its "Hisho" jet research aircraft at Noto Satoyama Airport, Ishikawa Prefecture, Japan, from September 12 to 30, 2016.
From the results of repetitive flyover noise source measurements, the noise reduction designs applied to the flaps and main landing gear of the "Hisho" were confirmed to be effective. In particular, noise from the flaps has successfully been lowered as intended at the design phase. It was the world's first flight demonstration test for noise reduction designs applied to high-lift devices.
The test was performed as part of JAXA's flight demonstration project for airframe noise reduction technology, FQUROH (Flight demonstration of quiet technology to reduce noise from high-lift configurations). The purposes of the preliminary flight demonstration are to establish all necessary processes required for flight demonstration such as aircraft modification and obtaining permission for flight tests as well as evaluation of the preliminary noise reduction designs.
Based on the evaluation results, JAXA will make further improvements to the noise reduction designs toward the flight demonstrations planned in 2017 under collaboration with the Aerospace Company of Kawasaki Heavy Industries, Sumitomo Precision Products Co., Ltd. and Mitsubishi Aircraft Corporation.
