03.2 - Experimental AerodynamicsRELEASE OF DYNAMICALLY SCALED OBJECTS FROM A HELICOPTER WIND TUNNEL MODELK.H. Lammers, NLR, Netherlands; I. Philipsen, DNW, Netherlands; M.H. Ryu, KAI, South Korea KAI contracted NLR to explore safe conditions under which objects can be dropped from a helicopter wind tunnel model in the DNW-LST. Objects are manufactured with rapid prototyping that comply with both geometrical and dynamical scaling laws. Trajectories are measured optically and repeated drops resulted in reproduced trajectories. For some trajectories unsteady aerodynamic forces are determined. |
