基于图像的测量技术背景定向纹影（BOS）和粒子图像测速（PIV）是特别有用的螺旋桨流的调查。执行专用测量的复杂性增加。初步研究是在单支桨上进行的。为了研究反推力和高升力条件下（正推力和零推力）的螺旋桨-机翼干扰，将模型复杂度提高到半模型。在每个阶段，这些技术都可以用作计算方法的验证。BOS可以很容易地应用，而无需太多的成本和准备。立体和单通道PIV设置的使用需要更多的准备。结果表明，BOS和PIV是研究螺旋桨瞬时流场不可缺少的工具。此外，它指出，PIV是一个非常宝贵的工具，用于数值验证的目的。
The image based measurement techniques Background Oriented Schlieren (BOS) and Particle Image Velocimetry (PIV) are particularly useful for the investigation of propeller flow. Dedicated measurements are performed of increasing complexity. Initial in-vestigations are performed with BOS and stereoscopic PIV on a single sting propeller. The model complexity is then increased to half-model for the investigation of propeller wing in-terference at thrust reverse and high-lift conditions (for positive and zero thrust). At each stage the techniques can be used as a validation for computational methods. BOS can readily be applied without too much costs and preparation. The utilization of stereoscopic and mono PIV set-ups requires more preparation. It is shown that BOS and PIV are indispensable tools for instantaneous propeller flow investigations. Furthermore it is stated that PIV is an invaluable tool for numerical validation purposes.
