FIELD: mechanics.
SUBSTANCE: system for forced waving of flags for advertising and similar devices consists of support intended for support of flag or similar element by means of stock for flag waving, and for attachment of blowing device which bleeds the flows of delivery air, which are directed to the flag and the component similar to it, which are located on the stock. Blowing devices have the possibility of delivering laminar air flow through outlet holes. Flag waving stock is located perpendicular to flow direction of laminar air flows, on outer side of outlet holes of blowing device and near them; at that, the flow is not subject to turbulence in the above zone. Two versions of system operation method are provided.
EFFECT: flag waving stability.
