  In this paper, we examined the low speed wind-tunnels. Our goal is to construct an open flow system windtunnel that can be utilized in our measurements. To make such a wind-tunnel we needed to build a prototype and calibrated with the help of measurements. Than we determined the flow at the area of measurement. Finally results of the measurements satisfied our expectations. Although there is still much more in development that we would like to do based on the newly gained experience.

  The current economical situation requires aircraft operators to start organizing their  activity in the direction of carbon neutrality using innovative solutions.

  The goal of present study is to desing a brand new wingtip device using 3D printing which helps reducing aerodynamical drag, leading to fuel efficiency and less carbon emission with its innovative shape.
