Tests were performed on a full model provided with installed Counter Rotating Open Rotor (CROR) engines. The 1:7 scale model, provided by the Topic Manager, was mounted on a dorsal sting, located at tunnel centre line. The model was provided with two powered Counter Rotating propellers which are driven by two air motors (owned by the Topic Manager). The model was basically the same as used in L-CROR CTS (JTI-CS-2012-01-SFWA-02-028). However, it was provided with 2 new engine configurations, new model parts representative of new engine configurations, new nacelle, new pylon and new blades, and airframe inflow variations.

The low speed wind tunnel test was offered in the DNW-LLF (Large Low speed Facility) 8m x 6m open test section.

The aim was generating high quality aerodynamic and aero-acoustic data.
