A flow separation reducer comprises a vane which prevents an airflow from being separated in a flow interference region where a plurality of members, such as a main wing and a pylon, are joined to each other. The vane is disposed in a location where the airflow along a surface of one of the members develops a minimum negative pressure. The vane has a predetermined angle of attack with respect to the airflow for generating a vortex downstream of the vane with respect to the airflow and causing a circulation around the vane to reduce the speed of the airflow in the location.

[ What is claimed is:] [1.] A flow separator reducer for preventing an airflow from being separated in a flow interference region where a plurality of members are joined to each other comprising a vane disposed in a location where an airflow along a surface of one of the members develops a negative pressure, said vane having a predetermined angle of attack with respect to said airflow for generating a vortex downstream of the vane with respect to said airflow and minimizing the speed of the airflow in said location, wherein said vane comprises a substantially triangular plate and has a pointed end positioned upstream with respect to said airflow, wherein said one of the members comprises a pylon with an engine nacelle mounted thereon and the other of the members comprises an aircraft wing supporting said pylon, said vane being mounted on said aircraft wing near a leading edge thereof, and another vane mounted on said engine nacelle downstream of the first-mentioned vane with respect to said flow.
