SHIP AIR PROPULSION COMPLEX

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to ship building. proposed complex comprises guide nozzle, bucket wheel and directing circular grating. Bucket wheel is fitted aligned on drive shaft inside said nozzle. Grating is arranged on guide grating inlet. Said grating is made up of radial vanes arranged regularly along the circle. Vanes feature symmetric profile formed by cylindrical section. The number of vanes is multiple of two but may not be less than eight. Roots of said vanes are attached to grating hub while peripheral ends are secured to nozzle case. Chords of vane profiles are parallel about guide nozzle lengthwise axis. Pair of vanes directed in opposite directions in circular grating is arranged along vertical. Length of said cords makes 0.8-1.5 of the distance between profiles along the circle in grating cylindrical section on radius equal to mean arithmetic distance between root and peripheral radii. ^ EFFECT: higher efficiency. ^ 2 dwg
