Snaps (Redneck translation for Robert Gainey)

[Jerry Budd]

Oh, OK Robert.  Since you asked, here it is in Redneck:

A win' is stalled when th' lif' curve slope changes sign, meanin' 
thet a further increase in angle of attack (AOA) results in a 
reduckshun in lif', due t'increased separeeshun of th' airflow 
disruppin' th' pressure distribushun on over th' top of th' win'. Th' 
AOA (also refered t'as "alfy" in th' flight tess wo'ld) at which th' 
lif' curve slope changes fum positive t'negative is whar th' maximum 
lif' coefficient (CL-max) of th' win' (o' vehicle) is retched an' is 
typically foun' t'occur aroun' 18 t'30 degrees alfy. It's a funckshun 
of a whole lot of thin's like aspeck ratio, planfo'm, corntrol 
surface defleckshun, Reynolds #, Mach#, etc. It is NOT a funckshun of 
airspeed, cuss it all t' tarnation.

But ah digress...
