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.
In the framework of the CleanSky project designated with the acronym LAc-LoRR OTS (Proposal reference number: 326005 - Call identifier: SP1-JTI-CS-2012-02 - Topic addressed: JTI-CS-2012-2-SFWA-02-030) low-speed aerodynamic tests were carried out on a typical A320 type passenger aircraft model, designated as the Z08 model. The tests were performed in the open 8 m x 6 m test section of the DNW-LLF low-speed wind tunnel. The Z08 model can be equipped with powered (compressed air) engine simulators, provided by Airbus to simulate the aerodynamic and aeroacoustic effects of an installed Unducted Single Fan (USF) propulsion system. The test was conducted in September/October 2016.
