- 0705 Aeroacoustic Sound Analysis around JAXA Landing Gear Model by Building-Cube Method
抄録
The noise from aircrafts at takeoff and landing has been regulated in all over the world airports. Now, aerodynamic noise from airframe such as a landing gear has been a problem. To analyze the aeroacoustic sound around a landing gear, we adopt aerodynamic/acoustic splitting method. We use a BCM three-dimensional incompressible solver as a flow solver and Curie's equation as aeroacoustic analogy and estimate the far field sound level. The present approach is then applied to JAXA-LEG model with the different components. The flow simulation and far field noise level is compared with experiments and numerical simulations to evaluate the usefulness and limitation for a future noise analysis around a landing gear.
