内容記述 | A far-field characteristic of a landing gear noise is assessed through lowspeed wind tunnel test in large scale anechoic facility of Railway Technical Research Institute. To understand landing gear noise generation of regional jet airliner during the approach phase, 40% of two-wheel type main landing gear scale model which is called LEG (Landing gear noise Evaluation Geometry) model is installed in open-jet test section. The model is designed in detail in order to reproduce flow field similar to that of around an actual landing gear, which is equipped with small instruments as well as large components such as a tire, a strut, a door and a brace. As a result, spectrum of sound pressure revel for fully dressed model configuration was obtained. The spectrum roughly corresponds to the empirical data given by EUDS database. Reynolds number effect and directivity in noise generation appeared at certain flow condition. In addition, the contribution and behavior of each component of the landing gear model to the total noise level was also assessed. The tire, the door and the brace were comparatively large noise source. It was shown that the spectrum of fully dressed configuration was reproduced by summation of the spectrum of each component, but some narrow band peaks were appeared depending on the model configuration. | |||||
