Yes ,
BUT,
Olde Pommie aeromudlers from the 50s regarded say a gliders wing section as at ) deg. A.o.A. , at its ' Neutral ' lift point/ inclination .
As in a datum across the chord where lift is neutral . Zero = or - .
( come up bigger so easier ti decipher here
https://rclibrary.co.uk/title_details.asp?ID=1012 )
Like a prop , the point its zero thrust at that R.P.M. and speed . ( which is unlikely to be the same as a line across the bottom ,
or even center ( if symetrical ) due to Philips Entry , and other drivle )
Following on from this approach , the A.o.A. , + or - , of a symetric airfoil at various flap deflections , when producing zero lift , would be iluminateing .
Along with the differance at those settings in angle required to produce the required lift .
Anaylisis , the more approches in perspective tend to broaden the scope of understanding . Like angles of flap deflection causing breakaway of flow .
But again theres variables varying that , when operating .
The big surprise is the small ange variation evedent in your film . again itd be intresting to see what happens when you ' stall turn ' it .
A favourite combat dodge , pre these large light combat jobs ..In effect a mushed square turn with trajectory alteration . Not the same
but comparable to a optimum square corner . Or is a ' clean ' square just outside these limits , or a mushed turn on the correct flightpath if at the ' impossable ' 5 Ft. radius ' correct ' . According to ' the Rules ' .
I tend to build in excess control travel , So I guess are saying I wonder what the recorder does when she is overcontroled or mushing , and where does it start to happen . Purely from a scientific point .
Like a 3 point fully stalled landing , on a carrier .
Good effort and glad to see you exploring the envelope there . Like I said , the yellow thing will rotate a corner in a gale which is usefull for avoiding being blown into the deck . For someone brought up on combat .
I guess all these years of development trying to get clean smooth square turns with mega powerplants to overcome the flap drag and maintain a even speed are contidictory or V c V ,
to the Roger Ramjet ( near ) STOP rotate POINT , which was said to be the 1960 trip where the sudden drag of the flaps allowed the square/ tight corner ( vertical )
But the ' Stall Turn ' principle still appies in the vertical as per the lateral . Just seems out of current usage ?
As In , wheres the buffet , and what happens past it . An essential in escape & evasion in dogfight control line, back then ( and now
) if not in P.A. , sorry to degrtess . Just trying to get that point across .
Do we get extra points for stall turns in F2B .
I take it your plane is the SV 11 , with the smooth operateing high load capeability section . That flys smooth forever , pretty much . Not a sharp nasty one .
