<p>The track is a reinforced concrete conduit (2) containing compressed air (3) and sealed by a deformable wing (5) under the action of the air and springs (6). Vertical conduit wing extensions provide room for vehicle air entraining skirts (16) and act as guides for the horizontal vehicle wheels (15). When stationary, the vehicle central wheel is raised and high friction skid pads (10) rest on high friction strips on the conduit (12), but when the central wheel is lowered, the compressed air is released, the vehicle lifts and inclined vanes along the vehicle bottom edge propel it in the required direction, the speed being determined by vane inclination.</p> |
