STEPPED ROTARY DEVICE Russian patent published in 2013 - IPC F01C11/00 F01C1/356 B64C15/02 

FIELD: machine building.

SUBSTANCE: stepped rotary device consists of a housing with rotary elements rotating in it. Rotary ball elements form independent rotary steps. Rotary steps simplify the device start-up considering their interaction and increase maximum number of the shaft revolutions. Stepped rotary device can be used not only as an engine with a big number of revolutions, but also as airborne and submersible vehicles, without changing major structural members of the device, at reduction of metal consumption of the item. In external housing and in internal members of rotary steps there can be arranged different loads, fuels and lubricants, people, as well as they can be used as receivers for exit gases. Steps with parameters necessary for obtaining external shapes of the device with improved aerodynamic characteristics are created by changing the diameter of balls and number of parallel chambers, by means of configuration of cover of external housing. As per the second version, stepped rotary device includes working chambers and exit gas outlet chambers interconnected between themselves via channels and known devices. Exit gas provides reactive motion through nozzles and changes its direction in space. Helicopter rotors can be mounted on the shaft of the stepped rotary device. Jet engines can be arranged inside external housing.

EFFECT: higher reliability of the device.
