1. A combustor for a rotating detonation engine, the combustor comprising:
a radially outer wall extending along an axis;
a radially inner wall extending along the axis, wherein the radially inner wall is positioned within the radially outer wall to define an annular detonation chamber having an inlet for fuel and oxidant and an outlet;
a flow passage for feeding oxidant to the inlet; and
a wall defined across a flow area of the inlet and an array of holes defined in the wall to induce turbulence to oxidant flowing through the array, wherein the array of holes are oriented along an array axis, wherein the flow passage comprises a first flow passage having a first passage axis and a second flow passage having a second passage axis, and wherein the array axis is oriented to the first passage axis or the second passage axis at an angle (β1) of between 10 and 30 degrees.
