Sectional Lift/Moment coefficients w/ sinusoidal motion

Click For Summary
SUMMARY

The discussion centers on understanding sectional lift and moment coefficients in relation to sinusoidal motion. Participants express the need for visual aids, such as figures or diagrams, to clarify the terminology used in the question. The term "h" is questioned for its definition, with suggestions that it may refer to altitude. The conversation emphasizes the importance of providing more context and work to receive effective assistance.

PREREQUISITES
  • Understanding of aerodynamic principles, specifically lift and moment coefficients.
  • Familiarity with sinusoidal motion in fluid dynamics.
  • Basic knowledge of aerodynamics terminology and notation.
  • Ability to interpret and create diagrams related to aerodynamic concepts.
NEXT STEPS
  • Research the relationship between sinusoidal motion and aerodynamic lift coefficients.
  • Study the effects of altitude on lift and moment coefficients in fluid dynamics.
  • Learn how to create and interpret aerodynamic diagrams and figures.
  • Explore resources on computational fluid dynamics (CFD) simulations for lift analysis.
USEFUL FOR

Aerodynamics engineers, students studying fluid dynamics, and researchers focusing on lift and moment coefficient analysis in varying motion conditions.

Homework Statement
An airfoil is given by a parabolic camber line, i.e., z=-(a/b^2)*x^2 (where a is a constant and b is the semichord length). Find the sectional lift and moment coefficients taken about the midchord for the airfoil undergoing a sinusoidal motion h = h(bar)sin(wt).
Relevant Equations
z=-(a/b^2)*x^2 (where a is a constant and b is the semichord length)
h = h(bar)sin(wt)
I cannot figure out how to even start this.

Can you post some figures that describe all of the terms that you are using in this question please? Use the "Attach files" button at the bottom of the Edit Window to attach PDF or JPEG files.

Also, what is h? Is it some altitude height? Or something else?

As I said, we can't give you much help until you show more work. But I'll ping @boneh3ad in case he can give you a hint or two for things to look into to start working more on this problem.
