Abstract
In the propulsion arrangement for an axisymmetric vehicle described in the specification, four propulsion modules are removably mounted at the rear of a vehicle in symmetric disposition about the vehicle axis, each module having an inlet section at its forward end which draws in the vehicle hull boundary layer without separation from the vehicle hull and supplies it uniformly to a rotating blade section driven by a rim drive motor. Control vanes for the vehicle are mounted between adjacent pairs of propulsion modules.
