Description: “MODERATE AND LARGE GUSTS ARE CAUSED BY FLOW AND OTHER COMPLEXITIES WHEN THEY INTERACT WITH VEHICLE LIFT SURFACES OR OTHER AERODYNAMIC SURFACES. A PRIMARY MOTIVATION IN STUDYING GUST ENCOUNTERS IS TO UNDERSTAND THEIR UNDERLYING PHYSICS AND DEVELOP NEW AND EFFECTIVE MITIGATION STRATEGIES.
THE PROPOSED PROJECT WILL COMBINE EXPERIMENTAL AND COMPUTATIONAL TOOLS ALONG WITH A NEW PATENTED WING DESIGN CONCEPT. THE GOAL IS
• EXAMINE NONLINEAR FLOW AND ELASTICITY MECHANISMS IN AEROELASTIC AIRFOIL RESPONSE
• QUANTIFY THE LOAD REDUCTION POTENTIAL THROUGH THE NEW AIRFOIL DESIGN.
FOR THE ANALYSIS OF THE EXPERIMENTAL AND RESULTS THAT USES DATA BASED ON DATA.
METHODOLOGY
DURING THE PROJECT, A SPECIAL GUST GENERATION MECHANISM WAS DESIGNED FOR THE WIND TUNNEL OF THE NATIONAL TECHNICAL UNIVERSITY OF ATHENS. THIS WILL BE COMBINED WITH THE EXISTING ELASTIC AIRFOIL SETUP TO CREATE A WORLD LEADING FACILITY FOR AEROELASTIC RESPONSE TESTING AT MODERATE RE NUMBERS (R<2M).
EXISTING, VALIDATED HIGH-FIDELITY FSI COMPUTATIONAL TOOLS (FSI INTERNAL SOLVER) WILL BE USED TO SHED MORE LIGHT ON THE DYNAMICS OF THE PHENOMENON. A DECOMPOSITION TOOL BASED ON OPEN SOURCE DATA WILL BE USED TO IDENTIFY KEY STRUCTURES IN THE STREAM. THE NEW CAMBER SHAPING AIRFOIL WILL BE TESTED AND COMPARED TO THE RIGID ONE TO QUANTIFY THE LOAD MITIGATION EFFECTS.”
