Can we use traditional signal correction for mixed conventional-3D Printed tube systems?

What is it about?

Pressure tubing is a common part of wind tunnel testing, connecting surface pressure taps on a model to pressure transducers. However, model geometry often prevent pressure taps from being where they are needed. Printing tubes integral to the model can overcome this, but results in tubes which have a rigid section and a flexible section. Furthermore, there are concerns about the loss of pressure through 3D printed walls. This paper examines the effect of varying the length of 3D Printed tube sections in a tubing network.

Why is it important?

3D Printing can be immensely valuable for overcoming pressure tap locating issues, but, if it were to impact the frequency response, would necessitate speicalised calibration for its frequency distortion. Hence, compatibility with existing tubing systems needs to be shown prior to use.
