A group of students designed a model drone with a scaling of 1:20 and tested it in a wind tunnel. The wind tunnel has a flow conditioning system that can produce a mean velocity of 70 m/s, and the drag force measured at this velocity is 350 N. If the drone in real size should operate at 35 m/s, a. determine the pressure inside the wind tunnel, b. determine the drag force that is acting on the real size drone.

Question

A group of students designed a model drone with a scaling of 1:20 and tested it in a wind tunnel. The wind tunnel
has a flow conditioning system that can produce a mean velocity of 70 m/s, and the drag force measured at this velocity
is 350 N. If the drone in real size should operate at 35 m/s,
a. determine the pressure inside the wind tunnel,
b. determine the drag force that is acting on the real size drone.
