Abstract

Propulsion apparatus for a transportation system vehicle. At least one gas producer is mounted on the vehicle for discharging a propulsive fluid stream. The propulsive fluid stream is directed against at least one longitudinally extending linear turbine assembly to propel the vehicle. A manifold delivers the propulsive fluid stream to the linear turbine assembly. A plenum beneath the vehicle receives the propulsive fluid stream from the linear turbine assembly to support the vehicle on a gascushion. Each linear turbine assembly includes cooperating nozzle blades and turbine blades mounted on the vehicle. Each nozzle blade has a longitudinal axis which is transverse of the fluid stream, the longitudinal axes of the nozzle blades all being substantially parallel to one another and to the longitudinal axes of each of the turbine blades, all of the turbine blades being substantially equally spaced from the nozzle blades. A plurality of ground-based stator blades having longitudinal axes which are substantially parallel to and equally spaced from the turbine blades and from the nozzle blades are positioned intermediate the turbine blades and the nozzle blades. In another embodiment, two linear turbine assemblies are oppositely directed and a valve assembly receives and selectively directs the propulsive fluid stream to a first linear turbine assembly to propel the vehicle in a forward direction and to a second, oppositely-directed linear turbine assembly to propel the vehicle in a reverse direction. In another embodiment, the vehicle includes laterally extending reverse flow nozzles mounted to the base of the vehicle above the plenum for selectively receiving the propulsive fluid stream to generate reversing or braking forces.
