The influence of perturbation motion over a slender delta wing under sideslip angle

Öz:
In this study, the main objective is to reveal the change of the vortical flow characteristics on a slender delta wing with a sweep angle of Λ=70º under the alteration of three different sideslip angles of β=0º, 4º, and 8º at three different main angles of attack of αm=25º, 30º and 35º experimentally. Dye visualization experiments were conducted at a Reynolds number of Re=2x104to analyze qualitatively. The perturbation motion which has amplitudes of α0=±0.5º and ±1º was applied continuously under the periods of time of Te=0.5s, 1s, and 2s. However, the effects of the low frequency perturbations to which the aircraft is exposed during the maneuver were examined. It is observed that Kelvin-Helmholtz in the case of the perturbed motion vortices is more prominent than static case results of the slender delta wing. The vortex breakdown location on the perturbed delta wing has been changed in a wider range than the static case of the delta wing at zero sideslip angle, β.

Öz:
Bu çalışmada, süpürme açısı Λ=70º olan narin (slender) delta kanadıngirdaplı akış yapısındaki değişimi, sapma açısı β=0º, 4º ve 8º karşısındakideğişimi, üç farklı ortalama hücum açısında αm =25º, 30º ve 35º boyadeneyi incelemesi amaçlanmıştır. Boya ile nitel görselleştirme deneyleri,Re=2x104 gerçekleştirilmiştir. Kanat modeli istenilen açıda sabitlenerekve elde edilen deney sonuçlar dikkate alınarak, α0=±0.5º ve ±1º genliğindeve Te =0.5s, 1s ve 2s periyotlarında kanata sürekli salınım hareketiverilerek girdap çökmesinin belirli ölçüde kontrolü sağlanmayaçalışılmıştır. Ancak, uçağın manevra sırasında maruz kaldığı düşükfrekanslı bozulmaların etkileri incelenmiştir. Kelvin-Helmholtzgirdaplarının narin delta kanadın daimî salınım hareketi verilendurumunda statik vaka sonuçlarından daha belirgin olduğugözlenmektedir. Narin delta kanatlarının sıfır sapma açısı, β salınımıhareketi anında; girdap çökme konumu statik durumdan daha geniş biraralıkta ileri ve geri hareket etmektedir.
