Abstract

An improved rotary engine that harmoniously produces multiple, sequential cycles. A main housing is comprised of a concentric stator sandwiched between a front and an aft wall enclosing a cylindrical inner space. A network of combustors are stationed about the stator periphery. Mounted on a central axis within the inner space is a concentrically revolving rotor body. The combustors sequentially introduce a working fluid into a plurality of expansion chambers symmetrically stationed within the rotor body. As the rotor is propelled by the working fluid, a variable vane transversely mounted within each expansion chamber simultaneously performs work on a fluid in a compression region. The compressed fluid of each cycle is discharged and diverted to compliment the combustor of a sequential cycle. A high degree of power and efficiency is achieved using simple mechanics to produce multiple cycles during each revolution.
