METHOD OF REDUCING AERODYNAMIC NOISE

摘要

FIELD: aero- and hydrodynamics. ^ SUBSTANCE: method comprises making a zone of reduced curvature on a part of the surface of the structure downstream of the line of flow detachment. The zone should have at least one continuous section. The construction is oriented so that the normal to the surface was close or in coincidence with the velocity vector. According to the second version, the method comprises choosing the zone of reduced curvature on the structure that is composed of a single continuous section and orienting the structure so that the normal to the surface is close or in coincidence with the direction of the flow velocity. ^ EFFECT: reduced aerodynamic noise. ^ 5 cl, 7 dwg
