STRAIGHT VS. SWEPT-WING STALL CHARACTERISTICS

摘要

On a conventional straight-wing/low-tailplane airplane, weight acts downwards forward of the lift acting upwards, producing a need for a balancing force acting downwards from the tail. As angle of attack increases, the tail encounters wing wake turbulence, the aerodynamic buffeting from which serves as a warning of impending stall. Reduced effectiveness of the tail prevents the pilot from forcing the airplane into a deeper stall.
