内容記述 | Low noise design concepts have been applied to regional jet two-wheel main landing gear to reduce airframe noise during landing approach. Those concepts were initially developed for the main landing gear of the JAXA's experimental aircraft, ''Hisho,'' based on the Cessna Citation Sovereign, and were tailored to the two-wheel main landing gear after a careful investigation of flow fields around it with computational fluid dynamics simulations, far-field noise measurements with a 10%- scale wind tunnel model and an evaluation of the structural feasibility. The initial design was then improved upon by further investigations with a 20%-scale wind tunnel model and additional computational simulations. Six types of low noise devices were prepared: a porous cover around the tire axle and the lower half part of the strut, a plate between the mid door and strut, a porous plate on the side brace, wheel holes sealed with aluminum tape, a door arm with porous plates. Significant noise reduction, 5.5 dB(A) in overall sound pressure level at a position directly below the main landing gear and 4.5 EPNdB, was achieved. | |||||
