报告题目:Aeroacoustic experimental study on landing gears and high liftdevices in D5 wind tunnel

主讲人:刘沛清/郭昊

报告时间:2017年11月29日(周三)16:00

报告地点:新主楼第1报告厅

报告内容简介:

The aerodynamic noise is a problem ofmodern large aircrafts, especially during takeoff, approach and landing stages.The airframe noise can be generally categorized into two components, namely thehigh-lift device noise and the landing gear noise. The noise generationmechanisms and the radiation characteristics are different from each other,such that the corresponding noise reduction methods are different. Recently,the 30P30N high-lift airfoil and the LAGOON simplified nose landing gear areexperimental tested in D5 aeroacoustic wind tunnel at Beihang University,aiming at revealing the noise generation mechanisms and far-field noisefeatures of these airframe components. Furthermore, some noise reductiontreatments and fundamental cavity noise are also presented.
