Marine Gas Turbine Engine Using a GTE to propel a ship goes back to 1937 when a Pescara free piston gas engine was used experimentally with a GTE.

The results demonstrate that compared to the conventional deflagration combustion, detonation combustion can significantly improve the thermodynamic performance of marine gas turbine under various condition. =���*[�@DC����g��&��x��}o�͇�8�UY�Z-�T� xref 0000230050 00000 n 0000011282 00000 n

Based on this concept, preliminary design was completed for a high-power marine gas turbine engine redesigned into a reverse one, which laid solid foundation for the following detailed design, experimental verification and application. The tests results show that the switching devices could operate flexibly and the output power reached over 40% of rated power condition.
