Continuous Detonation Combustor Operating on a Methane–Oxygen Mixture: Test Fires, Thrust Performance, and Thermal State

Aerospace
Test fires of a rotating detonation engine (RDE) annular combustor operating on a methane–oxygen mixture were conducted. Compared to the original RDE combustor previously tested, it was modified in terms of changing the layout of the water cooling system,

Combustor and turbine aerothermal interactions in gas turbines with can combustors

, 2016
As the research into the improvement of gas turbine performance progresses, the combustor- turbine interface becomes of increasing importance. In new engine designs components come closer together and the study of the combustor and turbine interactions can prove to be valuable for the improvement of the aerothermal performance of the vane.
