Abstract
A gas turbine engine comprises at least a power output turbine unit (POT), which is rotatably arranged inside an outer housing unit, and a compressor-turbine unit (CTU), which is rotatably arranged inside the POT, and the CTU, POT and outer housing unit are arranged about a common axis of rotation (CL). The POT and the CTU are arranged in such close proximity (d) that a dynamic friction coupling is generated between the POT and the CTU.
Claims20
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).
