Great lecture, May I ask why you assumed that the two modes (h and theta) have the same frequency p? Knowing that their motion is totally different from each other? 53:40
Thank you for the lecture, professor. It was very clear. But i have one question: why the solutions of the determiant have only two real and imaginary parts? The fourh order polinom shouldn't have four real and imaginary parts? Sorry if this is a algebraic misunderstand. Thank you again
My guess is yes, but flutter usually doesnt happen at lower wind velocity. Tip deflection will be the bigger issue for larger blades, however, maybe for smaller blades flutter could happen? You bring up an interesting question. I bet small blades yes, but not for large blades
I think the assumptions are that the flow is in the Steady State and the velocity of the fluid is much faster than that of the solid, in a way that it is reasonable to neglect the feedback motion effect of the solid on the behaviour of the fluid. But I didn't know why he assumed that the two motions (h and theta) has the same p, and what is consequence of substituting different parameters for the frequency (p1 and p2) for example?

p are natural frequencies. Each natural frequency acts on all coordinates.

Really clear explanation. Thanks for sharing!
This was a really clear lecture!
great video, thanks for sharing. I would like to knox if you don't have an example of application.
How can I write the dynamically uncoupled equations?
Interesting! Thank you for the explanation. It will great if you can explain LCO sir.
And in the statique pleaz? and thank you verry match
thanks for your meaningful lesson
Could we apply for wind turbine?
My guess is yes, but flutter usually doesnt happen at lower wind velocity. Tip deflection will be the bigger issue for larger blades, however, maybe for smaller blades flutter could happen? You bring up an interesting question. I bet small blades yes, but not for large blades
What course is this from?
for what flows is this eqtn valid will it work for laminar ?

Eres latino ??
pitching moment zero? thats not correct.
It is correct for a symmetric aero foil, which is the case of this example.
