METHOD OF WIDENING ZONE OF SUPPRESSION OF GROUND VORTEX CREATED BY AIRCRAFT ENGINE, ACTIVE SYSTEM FOR REALIZATION OF THIS METHOD AND AIRCRAFT ENGINE EQUIPPED WITH SUCH SYSTEM

摘要

FIELD: arrangement of auxiliary facilities of flying vehicles. ^ SUBSTANCE: proposed active system includes pneumatic system connected with compressed air source, unit with working member provided with movable nozzle and drive for control of movable nozzle in longitudinal and transversal directions. Pneumatic system is provided with shut-off valve connected with engine compressor and drive connected with shut-off valve outlet. Provision is made for guide section so located relative to engine air intake that jet of air escaping from nozzle breaks structure of turbulent flow of ground vortex, thus excluding its suction by engine. Active system is designed for aircraft engine for suppression of ground vortex. ^ EFFECT: reduced probability of damage to engine by foreign matter. ^ 22 cl, 22 dwg
