FIELD: transport.
SUBSTANCE: invention relates to aircraft systems of aerosol protection, in particular to pulverisation of liquids using injectors which are used to create aerosol protective tail lowering intensity of infrared radiation of aircraft engine exit. Gas-liquid injector contains constricted nozzle with resilient walls the inner surface of which is provided with vortex-generators, and liquid and gas delivery lines. To disperse liquid with powder filler the constricted nozzle is performed slotted and communicates with liquid delivery line only. Along periphery of slotted nozzle, a nozzle is located which is communicated with gas delivery line on inner walls of which thrusts are made. Such device implementation permits to decrease average size of sprayed liquid drops and to increase degree of its monodispersity.
EFFECT: increased reliability degree of aerosol protective shield, and small size of aerosol particles allows for more efficient engine shielding against IR radiation.
