Abstract

This paper describes a wake survey system used to improve the understanding of the underlying flowfield and aerodynamics of a swept wing with ice accretions. This system allows the rapid collection and analysis of large amounts of flowfield data by utilizing an array of five-hole probes on a precisely controlled traverse arm. Flowfield structure on the surface of the wing is acquired using an oil flow visualization technique and correlated to the associated wake survey. This method allows quantitative calculations such as spanwise lift and drag to be compared with qualitative measurements and observations to enhance the understanding of the aerodynamics of wings containing ice accretions. Wind tunnel tests for a range of configurations are presented and analyzed in this paper. Results based on this wake survey method are compared with traditional measurement techniques such as force balance measurements to assess their accuracy.
