Fluidic actuator

摘要

A fluidic actuator (64) comprising: a fluid nozzle (52) for delivering fluid and a tube (56) having an open end (58) and a closed end (60), the open end (58) spaced from the fluid nozzle (52). Also a pair of electrodes (66) mounted in the tube (56) and spaced apart to create a spark gap therebetween. A voltage source (68) is arranged to supply a voltage across the pair of electrodes (66) wherein the voltage causes plasma formation in the spark gap thereby shortening the effective length (x) of the tube (56).
