Aerofoil section with lift-increasing trailing edge, in which trailing edge has spoilers on one or both sides to cause flow breakaway

摘要

The aerofoil section has a suction side and a compression side when a flow passes round it. The trailing edge (2) diverges or is angled away from the rest of the section. The trailing edge has spoilers on both sides to produce a periodic flow breakaway or to stabilize the flow. Anti-backflow spoilers may also be included.
