Main shaft free type axial flow air compressing mechanism and air compressor

摘要: The invention belongs to the fields of propulsion technology and aviation power devices, discloses a main shaft free type axial flow air compressing mechanism an compressor. comprises case, annular motor, blade disc plurality blades; one ends blades are connected with inner side theannular disc, other extend towards circle center in radial direction; outer is withone end motor used for driving rotate, case. directly surface thus, driven by speed reductionand pressurizing effects can be achieved after airflow passes through grid channels accordingly, effect achieved, size remarkably decreased, equipment weight compressor lowered obviously, unit area mass rate aircompressor increased, capacity improved, stable working range broadened, damage probability reduced, overall stability improved.
