The knowledge acquired and the solutions developed will be evaluated through large scale tests : tests in wind tunnel which allow simulating extreme conditions occurring during flights, on a test aircraft (short flight tests) equipped with a cameras and sensors (T°, RH, pressure) to monitor all the parameters responsible of real condition contamination and on a commercial aircraft (long flight tests) flighing at higher altitudes and allowing a full validation of the newly developed solutions.
As a summary, the project STELLAR aims at producing sustainable solutions to :
reduce drag on aircrafts
enable laminar flow over time with direct impact on fuel consumption
contributes to aviation’s ecological footprint reduction, targeting a 50% reduction of wing friction and up to 5% lower CO2 emission.
