  • Patent number: 11781754
    Abstract: The application relates to an assembly for controlling detonation wave mode of a rotating detonation combustion chamber, which includes an inner barrel, an outer plate and at least one sectoral direction-changing block. The outer plate is sleeved outside the inner barrel. An annular cavity is formed between the outer plate and the inner barrel. At least one groove is arranged on one side of the outer plate close to the inner barrel. The groove wall comprises an arc edge and a straight edge. The groove is connected with the annular cavity. The sectoral direction-changing blocks are arranged in the grooves in one-to-one correspondence. An arc edge of the sectoral direction-changing block is positioned far away from the inner barrel.
