slat/slot
Especially in the last image,the authors need to qualify the flight envelope for the pictured wing.
Up until a certain velocity,there would be no 'compression' of the air,only acceleration,and an attendant pressure drop.
On automobiles this would be 250-mph.
Fixed-slats and slots are of the highest drag configuration for a wing.
The Fieseler Storch,with almost helicopter-like STOL characteristics has one of the highest drag coefficients measured for an aircraft.
