A non-dimensional group relevant to flapping flight the Strouhal number, St - Ewhere f is the frequency of wing flapping in [1/s], L is the length of the wing, and U is the flight speed. Geometrically, the ratio of wing length to body size, L/B, is important. An Andean Condor during gliding flight flaps its wing with a frequency of 2 [1/s] with a velocity of 15 m/s. It has a wing length is 1.5M and its body size if 1.2m. T4 Assuming St and L/B is all that is needed for dynamic similarity i.e V2 LB Answer the following questions I wish to make a robotic model of the Andean condor that exhibits similar flight dynamics, however I can only make my model have a wing span of 0.25m and the motor I am using has a fixed frequency of 10 [1/s]. Please tell me how fast my model must go and the size of its body to make it dynamically similar. 1. 2. I measure a Drag force of my model in air of 10 N. What is the real drag force on the condor? Assume a density of air of 1.225 kg/m3
