Abstract
A propulsion system includes at least one rotating detonation actuator comprising: a flow path extending from an inlet end to an outlet end; an inner wall defining a radially inner boundary of the flow path; an outer wall defining a radially outer boundary of the flow path; and at least one aircraft wing. The rotating detonation actuator is disposed in the aircraft wing. At least one rotating detonation wave travels through the flow path from the inlet end to the outlet end.

A propulsion system comprising:
- at least one rotating detonation actuator comprising:
- an annulus extending from an inlet end to an outlet end;
- an inner wall defining a radially inner boundary of the annulus;
- an outer wall defining a radially outer boundary of the annulus;
- and
- an annular engine casing, the annular engine casing comprising an engine exhaust section,
- wherein the at least one rotating detonation actuator is disposed in the engine exhaust section of the annular engine casing, and
- wherein at least one rotating detonation wave travels through the annulus from the inlet end to the outlet end.

A thrust vectoring system comprising:
- at least one rotating detonation actuator comprising:
- an annulus extending from an inlet end to an outlet end;
- an inner wall defining a radially inner boundary of the annulus;
- an outer wall defining a radially outer boundary of the annulus;
- at least one flow surface disposed downstream of the outlet end;
- and
- a plurality of fuel injectors disposed in at least one of the inner wall and the outer wall, the plurality of fuel injectors circumferentially spaced around the annulus,
