Jet engine test cells provide a controlled testing environment necessary to obtain engine performance measurements that are reliable and repeatable. When constructing a test facility, it is important to consider how its components affect the characteristics of the airflow passing through it. In this regard, the distribution of the flow velocities reaching the engine intake can influence its performance and even compromise its operation. Another important aspect, that is affected by the test cell aerodynamic performance, is its structural integrity, as it must be compatible with the internal wall pressure drop, which varies in severity depending on the cell architecture. In the past, the aerodynamic performance of an engine test cell was studied primarily using fluid dynamic similarity tests conducted on scale models, in order to save on construction time and costs.
