METHOD FOR REDUCTION OF FRONT DRAG AT FLOW OF BODY BY FLOW OF LIQUID OR GASEOUS MEDIUM Russian patent published in 2020 - IPC F15D1/12 B63B1/34 

Abstract RU 2718816 C1

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding, aircraft engineering and can be used for creation of hulls of ships and aircraft with reduced resistance of environment to their movement. Proposed method consists in installation of injection channels in front part of vessel, at that, in addition, in its frontal part injection channel is supplemented with sink providing change of flow direction along circular channel to increase pressure in axial part of channel and reducing distance between inlet and outlet channel on front part of ship, note here that channel outlet part features slot-like shape with its width equal to that of channel inlet while lateral channels have slotted structure with inlet part thicker than outlet section.

EFFECT: technical result consists in considerable reduction of front drag at flow of body by flow of liquid or gaseous medium.
