AN INVESTIGATION OF V/STOL JET INTERACTIONS IN A CROSS FLOW

THE ABILITY TO OPTIMIZE THE DESIGN OF V/STOL AIRCRAFT AND TO PREDICT THEIR PERFORMANCE REQUIRES A GOOD UNDERSTANDING OF THE COMPLEX JET-INDUCED PHENOMENA ASSOCIATED WITH THESE AIRCRAFT. PRESENTLY, EXPERIMENTAL WORK IS THE MAIN AVENUE FOLLOWED TO GAIN AN UNDERSTANDING OF V/STOL FLOWS. NUMERICAL SIMULATION HAS MANY ADVANTAGES NOT SHARED BY EXPERIMENTAL TOOLS. IT, THEREFORE, CAN COMPLEMENT EXPERIMENTAL EFFORTS IN GAINING A DEEP UNDERSTANDING OF THE COMPLEX FLOW PHENOMENA ASSOCIATED WITH V/STOL FLOWS. USING THE LARGE-EDDY SIMULATION APPROACH, THE OBJECTIVE OF THE PROPOSED WORK IS TO INVESTIGATE THE COMPLEX JET INDUCED INTERACTIONS ASSOCIATED WITH AN AIRCRAFT IN PITCH AND A FORWARD MOVING AIRCRAFT.
