METHOD OF AND DEVICE FOR BUILDING TRACTION OF VEHICLE Russian patent published in 1998 - IPC

FIELD: transport engineering; railway transport; high-speed air-cushion trains. SUBSTANCE: air flow built in variable-section closed circulation contour is directed on fixed vanes installed along entire path. Circulation contour has blower, nozzle guide vane assembly and diffuser, all mounted on vehicle. Fixed vanes pass between guide vane assembly and diffuser. In proposed method power acting device is used which is essentially a common unit consisting of series connected air blower with drive, nozzle device and diffuser installed on vehicle. Clearance is provided between nozzle device and diffuser to pass guide vanes. All members of unit and guide vanes form closed circulation contour. Power interaction unit can be installed on supports for transverse displacement and is provided with device for centering relative to guide track. It is expedient to furnish nozzle guide vane assembly of such device with mounting angle adjuster. EFFECT: increased efficiency at traction building, no adverse effect on environment. 4 cl, 2 dwg
