well, i was just hoping for some aerodynamics explanation...
Let's just forget about the definitions of Vmca or the regs and the fact flaps have to be in the TO config for the demo.
How will flaps being lowered or raised affect the Vmca? and i am not interested in just knowing if it will increase or decrease it.
hugh flung_dung started with a good point, i do understand there will be an increase in the asym rolling moment due to the increased lift on the blown wing compared to the failed wing.
Why do you say that the flaps will cause an increase in drag which will lead to an increase in asymmetric yawing moment? The form/parasite drag will be equally increased on both wings but does the decrease in induced drag due to the increase in lift on the blown wing has anything to do with it?
Most of the books/manuals i have referred to just stay vague about it..
Thanks for your help
I'm just trying to come up with a real and valid explanation in front of my students
