ABSTRACT:
There is proposed a lift and propulsion unit for an air-cushion transport vehicle, with an axial fan installed at the entrance portion of an annular duct and at the exit of said annular duct is disposed a thrust nozzle comprising a reversing-and-steering device with independently rotatable rudder blades and reversing vanes installed in the walls of said thrust nozzle after said axial fan; said rudder blades close the exit section of said thrust nozzle during reversal of the thrust and make with each other an obtuse angle whose apex is directed toward said axial fan, and the side walls of said reversing-and-steering device are made in the form of a polyhedral vaned surface each facet of which is comprised by a cascade of bow-shaped reversing vanes.
The invention may be used in the development of air-cushion transport vehicles, self-propelled transport platforms and apparatus in which the translatory motion is effected due to a reactive thrust provided by the ejected air stream.
