SUMMARY

This discussion focuses on calculating the forces acting on a wing in a wind tunnel with an airspeed of 2.5 m/s. The user employs a method involving a square grid for visual displacement measurements before and after airflow activation. Key concepts include static equilibrium and the importance of knowing the mass and center of gravity (COG) of the wing to determine the forces accurately. The user seeks confirmation on the feasibility of this approach and the relevant equations for force calculation.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Knowledge of aerodynamic forces and their calculations
  • Familiarity with center of gravity (COG) concepts
  • Experience with wind tunnel testing methodologies
NEXT STEPS
  • Research the equations of motion for aerodynamic forces
  • Learn about the application of static equilibrium in fluid dynamics
  • Study methods for measuring displacement in wind tunnel experiments
  • Explore the impact of airspeed on lift and drag forces
USEFUL FOR

Aerospace engineers, physics students, and researchers involved in aerodynamic testing and analysis will benefit from this discussion.

This is a followup for my project which has been on a previous forum post: https://www.physicsforums.com/threads/wind-tunnel-measurements.856773/

I'm now trying to work out the forces on the object when under the influence of a 2.5m/s air speed and also knowing the mass of the object. My wind tunnel has the object, wing in this case, hanging from the top with elastic. The next video shows the forces I predict the wing to have.



Using a square grid (graph paper) behind the object I will take a picture of the location of the wing then turn the air flow on and take a second picture (with the camera in the same place). I predict that V1 and V2 will be of opposite signs (- and +) because of its shape.

I'm wondering if firstly this is at all possible and secondly the equations I could use to work out the forces labeled in the diagram.

Yes, you can apply static equilibrium to find the force of H.
You'll need to know the mass and COG location for the wing.
