FIELD: mechanics.
SUBSTANCE: proposed ejector is intended for pumping gases from aerodynamic apparatuses and chemical lasers and comprises narrowing mixing chamber, neck, subsonic diffuser and supersonic central nozzle. The nozzle outlet edges accommodate regularly arranged miniature swirlers representing tabs inclined towards ejected gas flow relative to the nozzle outlet edge by an angle of up to 10°. Optimum number of tabs makes 2 to 4.
EFFECT: increased ejection factor at preset compression ratio, reduced chamber length.
