Abstract
A transportation system has an air cushion vehicle in a U-shaped or W-shaped channel in the ground. The channel provides support and directional stability for the air cushion vehicle during transit along its length. This system assures high speed overland transport of heavy equipment which is faster than trains, and the system is cost effective since it does not incur expensive nonrecurring capital investments and expensive recurring maintenance costs. This transportation system is adaptable to existing overland right-of-ways.
Claims4
A transportation system comprising:
- an air cushion vehicle in a channel in the ground to provide support and directional stability for said air cushion vehicle during transit therein;
- a barrier layer covering surfaces of said channel to prevent ablation of said ground by pressurized air from an air cushion;
- panels on the periphery of said vehicle disposed in said channel, said channel being a W-shaped channel, said panels including left and right side panels on opposite lateral sides of said vehicle and extending its length and a portion of the depth of said W-shaped channel and front and rear panels extending across the width of said vehicle and a portion of the width of said W-shaped channel, said panels further including two intermediate panels between said left and right side panels extending parallel therewith for the length of said vehicle and a portion of the depth of said W-shaped channel, and said front panel having a left part and a right part adjacent one another to extend across the width of said vehicle and said back panel having a left part and a right part adjacent one another to extend across the width of said vehicle, said left side panel, one of said intermediate panels, said left part of said front panel, and said left part of said rear panel bounding and defining first air cushion part of said air cushion, and said right side panel, the other of said intermediate panels, said right part of said front panel, and said right part of said rear panel bounding and defining second air cushion part of said air cushion, said first air cushion part and second air cushion part are each disposed in a separate elongate channel portion of said W-shaped channel.
A transportation system comprising:

- a barrier layer covering surfaces of said channel to prevent ablation of said ground by pressurized air from an air cushion;
- panels on the periphery of said vehicle disposed in said channel, said channel being a W-shaped channel, said panels including left and right side panels on opposite lateral sides of said vehicle and extending its length and a portion of the depth of said W-shaped channel and front and rear panels each extending across the width of said vehicle and a portion of the width of said W-shaped channel, said panels further including two intermediate panels between said left and right side panels extending parallel therewith for the length of said vehicle and a portion of the depth of said W-shaped channel, and said front panel having a left part and a right part adjacent one another to extend across the width of said vehicle and said back panel having a left part and a right part adjacent one another to extend across the width of said vehicle, said left side panel, one of said intermediate panels, said left part of said front panel, and said left part of said rear panel bounding and defining first air cushion part of said air cushion, and said right side panel, the other of said intermediate panels, said right part of said front panel, and said right part of said rear panel bounding and defining second air cushion part of said air cushion, said first air cushion part and second air cushion part being disposed in a separate elongate channel portion of said W-shaped channel, said first air cushion part and second air cushion part each generating forces to stabilize said vehicle as it transits said W-shaped channel;
- and
- a skid and wheel on each of rigid sidewalls on opposite sides of said vehicle to contact said W-shaped channel for stability and braking.
