ENGINE-PROPULSOR PLANT OF DYNAMIC AIR CUSHION VEHICLE Russian patent published in 1998 - IPC

FIELD: transport engineering; engine-propulsor plants for wing-in-group-effect craft. SUBSTANCE: proposed plant has two propulsors, each made in form of propeller installed on shaft arranged in ring member mounted on fuselage pulon and provided with load bearing spokes and connected by shafting with engine or it reduction gear installed on wing, and propulsor turning-lifting mechanism. According to invention, each shafting is made in form of propeller shaft installed in load bearing casing. Each propeller shaft is sectional, consisting of at least two sections, and is furnished with intermediate shafts in number corresponding to number of sections. Load bearing casing has number of intermediate supports corresponding to number of intermediate shafts. Ends of load bearing casing are movably connected with engine or its reduction gear and propulsor. Propeller shaft sections are connected with intermediate shaft for limited displacement. Ring member can be made with axial hub furnished with bearing unit for propeller. Load bearing casing can be made sectional with end telescopically connected spherical supports, and intermediate supports can be detachably connected with sections of casing. Each intermediate support can be furnished with inner bearing unit for intermediate shaft which can be provided with spline connections with propeller shaft sections. Propulsor turning-lifting mechanism can be furnished with bellcrank with drive mechanism. EFFECT: enlarged operating capabilities. 7 cl, 2 dwg
