Tests were performed on a full model with installed CROR engines. The model was mounted on a ventral 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 aim of the test was to determine the aerodynamic performance and stability & control characteristics of a CROR powered aircraft. During the test, innovative measuring techniques and hardware solutions were used to assess the aerodynamic signature.
The test was performed in the 8mx6m closed test section of DNW-LLF.
In the framework of the CleanSky project, a low-speed aerodynamic test was carried out on a large CROR aircraft model. The test was performed in the closed test section of the DNW-LLF low speed wind tunnel. AIRBUS had designed and manufactured a 1:7 scale model of a future A320 like aircraft with CROR. The test was conducted in August and September of 2012.
Main objectives for the test were as follows:
- Establish a data base in order to obtain handling quality data for an aircraft with two CROR's at the tail section:
- Measure aero-elastic data for the HTP and VTP.
