DUST-PROTECTION DEVICE FOR FLYING VEHICLE ENGINE |
摘要 |
flying vehicle engines. SUBSTANCE: proposed device includes straight-flow cyclones secured between inner and outer tube sheets forming dust collector cavity with dust removal passage. Cylindrical housing of each cyclone is provided with blade-twisting apparatus-swirler with taper diffuser provided in its outlet section. Mounted inside diffuser coaxially relative to cyclone housing on inner tube sheet is purified air discharge tube, thus forming circular passage for removal of separated dust to dust collector. Invention contains relationships of cyclone geometric parameters. EFFECT: reduced hydraulic resistance at retained efficiency of cleaning simplified construction. 3 cl, 3 dwg
