you could use a spring behind your object, and calculate inline reaction force from deflection.
it will be essential the wind speed is accurately measured
force will represent wind velocity squared *drag coefficient , once calculated the drag coefficient can be used elsewhere, in acceleration calculations for instance.
measuring forces versus wind speed should produce a exponential graph in the form f = v^2 as drag force is proportional to square of velocity
if you translate the action into freefall , at terminal velocity the forces balance,
down = mass * gravity acceleration ( newtons)
up = velocity ^2 * drag coefficient (newtons)

Tunnel sheilds are used to hold it up.
it is a simulation of real running turbine or compressor blades, since it is difficult to study a rotating and mooving machin, its better to fix the blade and let the air circulate, then study all the parameters... bilal el samad mechanical engineer

Wind Tunnel
In the most recent tour de france, Lance Armstrong had special clothing designed for his time trial race. It featured different fabrics that channeled wind around his body smoother by altering flow and direction.

wind tunnel
a wind tunnel works by turning on a gigantic fan in a round tunnel they place the car SUV etc. in the tunnel and turn the fan on to see if its aerodynamic since we cant see air they put a fog machine to make stream of fog to see the aerodynamics of the car the faster the fog passes the more aerodynamic it is
Computer models are used extensively and in a wind tunnel
Engineers use them to study the aerodynamic properties of items they are designing, like cars, aircraft, etc.
The most valuable measurement within a wind tunnel is pressure, specifically the differential between the upper and lower surfaces of the airfoil as this is the 'engine' that provides lift. This changes as the angle of attack changes, as the airspeed changes, and as the apparent wind direction changes. The wind tunnel lets us observe how the airfoil reacts to different conditions so we can optimize the shape for its intended use.

Wind tunnels move air around an object making it react as though it was moving itself. It lets the design team know what changes can be made to increase the effectiveness of their design. Not only is it used for aircraft, it's also used for trains, automobiles and the like.

A wind tunnel is an enclosure set up to test the aerodynamic properties of aircraft shapes, vehicle shapes or other things that move through the air. The wind tunnel is generally a big "tube" or sorts, and it is closed on itself. Inside we'll find a large fan, air turbine or the like, and a test chamber where the structure being tested is set up. With a model, mock-up or the like posted on something to hold it in place, the test personnel leave the chamber, and the machinery that moves the air is started. The moving air rushes past the test shape, and different methods of evaluating airflow across and around the item are used. Wind speeds can (and do!) reach hundreds of miles per hour in many of the tunnels, and safety is an important consideration when operating them.
