Abstract:
A system for modifying a high speed fluid flow, comprising:an aerodynamic surface adjacent or within the high speed fluid flow; and a deflagration combustion-driver jet actuator provided on the aerodynamic surface, the jet actuator including a combustion chamber, a spark generating device that supplies ignition sparks within the combustion chamber to ignite fuel, an orifice that serves as an outlet for combustion products emitted from the combustion chamber, and at least one inlet through which fuel is supplied to the chamber for combustion, wherein the combustion frequency of the jet actuator is controllable with the spark generation device so that the jet actuator can emit jets of fluid at various different frequencies; wherein actuation of the jet actuator causes a jet to be emitted that modifies the high speed fluid flow.
