Abstract

An ultra high-speed transportation system comprising a prepared tube for moving people and cargo in vehicles being propelled by a variable-speed motor ultra high-speed air stream generator, a continuous moving ultra high-speed air stream of air within the prepared tube that is end to end, or continuous without end, with a series of load-unload stations that do not have the stream moving through the station. The air stream is bypassed around the station back into the main transportation tube, so as not to interfere with loading and unloading of the vehicles. The vehicle when traveling in the tube is kept from the tube wall and kept in the approximate tube center by the force of the moving air stream, having to move around and past the vehicle that fills only about two thirds of the tube's opening, because the air stream is moving at a higher rate of speed than the vehicle. In ground level where the transportation tube direction in elevation changes up or down, to keep the gravitational forces from becoming intolerable on the passengers, an air stream generator is used to bypass some of the air stream to lower the vehicle speed. In movement of non-living cargo optimum speed is used, disregarding the G. forces.

Claims5

Dependent claims

A high-speed pneumatic transportation system comprising:

a main line having a tubular cross-section and defining a travel path, said main line including at least a horizontally oriented section connected to at least an inclined section;
at least one vehicle movable along inside said main line;
generator means for generating an air stream inside said main line for forcing said at least one vehicle to move along inside said main line;
vehicle speed reducing means provided generally at said inclined section for reducing the speed of said at least one vehicle generally at the inclined section so as to lower gravitational force imposed on passengers in said at least one vehicle;
said vehicle speed reducing means including a first means, located near an entry to said inclined section, for bypassing a portion of the air stream inside the horizontal section and directing said portion of the air stream against the front end of said at least one vehicle travelling toward the inclined section, so as to reduce the speed of said at least one vehicle travelling toward the inclined section;
said vehicle speed reducing means further including a second means, located at the inclined section, for bypassing a portion of the air stream around said inclined section, for reducing the air stream in the inclined section.
