Claim 0:
1. A gas turbine engine, having a central axis of rotation (CL) and comprising at least:
an outer housing unit having a first opening and a second opening and an exhaust gas outlet;
a power output turbine unit (POT) comprising an output shaft and a first circular portion forming a first shaft about the central axis (CL), the POT rotatably arranged inside the outer housing unit, and comprising a compressor housing section and a third stage;
a compressor-turbine unit (CTU), rotatably supported inside the POT, having (i) a first stage and (ii) a second stage rotatably arranged inside the third stage of the POT, wherein the first and second stages being interconnected by a second circular portion forming a second shaft about the central axis (CL), the second circular portion also forming an air inlet; and wherein:
a portion of the air inlet is rotatably supported by the first opening of the outer housing unit,
the output shaft of the POT is rotatably supported by the second opening of the outer housing unit,
a combustion chamber is formed by a portion of a wall of the outer housing unit and a portion of the first shaft,
the first stage is rotatably arranged in the compressor housing section, such that air or other gases having passed the first stage are ejected into the combustion chamber, and
the CTU, POT and outer housing unit are arranged about said central axis of rotation (CL).
