The invention discloses a fuel injector, a rotary detonation engine and an aircraft. The fuel injector comprises a main body provided with an annular containing cavity and an annular combustion chamber, the containing cavity is located on the radial outer side of the combustion chamber, a common wall is arranged between the containing cavity and the combustion chamber, material leakage holes are distributed in the common wall, and the containing cavity and the combustion chamber are communicated through the material leakage holes; the fuel and the elastic pressing device are both arranged in the combustion chamber, and the elastic pressing device presses the fuel on the common wall; the pressure detection device is arranged to detect pressure data of the elastic pressing device; the vibration generating device is arranged on the common wall and drives the common wall to vibrate; and the control device is electrically connected with the pressure detection device and the vibration generation device, the fuel is solid powder fuel, and the control device controls the vibration generation device to drive the common wall to vibrate at the set amplitude and the set frequency according to the pressure data and fuel demand data of the combustion chamber, so that the material leakage amount of the material leakage hole meets the fuel demand data. And combustion of the solid powder fuel is accurately controlled.
