ABSTRACT:
A method of controlling the flow of gas emerging from the outlet of a fluidic vortex valve, the method comprising feeding a supply fluid to an inlet of the vortex chamber associated with the fluidic vortex valve whereby a supply gas flow is injected into the vortex chamber in a substantially radial direction, feeding in a controlled manner via a valve member a control fluid to a second inlet of the vortex chamber whereby a control fluid flow is injected into the vortex chamber in a substantially tangential direction wherein the improvement lies in providing that the control fluid is in the form of a liquid monopropellant at least until after it has flowed past the valve member, and providing means for igniting the liquid monopropellant thereafter to generate the control gas flow in the vortex chamber.
