Influence of nose configuration of flowed-around models on structure of three-dimensional pressure fluctuation fields

Influence of nose configuration of flowed-around models on structure of three-dimensional... Abstract A series of tests on determining the structure of pressure fluctuation fields arising during the flow past cylindrical models with nose cones of different configurations has been carried out. It is shown that, depending on the configuration, a change in the angle of attack can lead to a significant transformation of pressure fluctuation fields on a cylindrical surface; the transformation manifests itself as an increase in spectral density and change in the degree of spatial interconnection of fields. The pressure fluctuation field on the surface of a model with a nose cone as a typical model of the forebody of a present-day high-speed civil aircraft is studied. Additional perturbations in this case are shown form even at a zero angle of attack of the model. The field of pressure fluctuations on the surfaces of models is studied in the longitudinal and circumferential directions. Comparison of the data of the model experiment with flight results in the literature shows that the results of the model experiments in general do not contradict field-test data. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acoustical Physics Springer Journals

Abstract

Abstract A series of tests on determining the structure of pressure fluctuation fields arising during the flow past cylindrical models with nose cones of different configurations has been carried out. It is shown that, depending on the configuration, a change in the angle of attack can lead to a significant transformation of pressure fluctuation fields on a cylindrical surface; the transformation manifests itself as an increase in spectral density and change in the degree of spatial interconnection of fields. The pressure fluctuation field on the surface of a model with a nose cone as a typical model of the forebody of a present-day high-speed civil aircraft is studied. Additional perturbations in this case are shown form even at a zero angle of attack of the model. The field of pressure fluctuations on the surfaces of models is studied in the longitudinal and circumferential directions. Comparison of the data of the model experiment with flight results in the literature shows that the results of the model experiments in general do not contradict field-test data.
