[Also in Division F2] A perforated strip 2 placed at the position of greatest curvature between the roof 1 and the back 4 to deflect the airstream over the body at this position thus reducing the lift thereof. To produce the same effect air under pressure may be blown out of a slot in the body at this position and this jet may be used to entrain air from inside the body to ventilate it.
