PNEUMATIC TUBE TRANSPORTATION

The results of basic research on the pneumatic tube system are used to project significant operating characteristics of a prototype pneumatic tube transportation system. The projections are based on an experimentally verified, numerically computed analysis and laws of similitude. Background and other pneumatic tube studies are noted. Vehicle speed variations on the guideway due to air friction and compressibility during a transit are shown for the prototype double-tube system to be acceptable at moderate speeds. Guideway power is shown to be strongly affected by vehicle average speed, to be essentially directly proportional to guideway discharge pressure, and to be little influenced by the vehicle weight. The technical feasibility of the investigated features of the concept is supported.
