Ok , I know I'm procrastinating, but have you ever had one of those times when you just want to think about something else?
I've been having one on and off for a few weeks now, and during this time, I have been reading and making observations.
So we know that aircraft maintain a certain degree of stability by offsetting the pitching moment with a horizontal component of lift.
We also know that in closely coupled aircraft that interference from the wing can greatly reduce the amount of force the horizontal stabilisor can deliver.
With these two principals in mind I began think about an aircraft that was both closely coupled (or relatively so) and has the horizontal stabilisers directly in line with the wings. much like the F-22.
Now it is my theory that aircraft similarly configured would not nessicarily get most of it's downward force from the horizontal, but from the angled verticals, which could quite concievably generate all of the downward moment required, allowing the horizontals to function as elevators only.
If this is so, and I hope I am on the right track, then this then leads me to a question: Would this give any significant improvement to the elevator response?
If this is so then why don't we see many people in the experimental scene incorporating this idea into a design to test it's effectiveness for GA and sport aircraft?
