leaving the expulsion chamber module 14 and increasing the velocity and range of the final output tee accelerator module 16 utilizes pressure and vacuum to draw the shock wave through the hemispherically shaped portion 50 of the expulsion chamber module 14 the inner member 52 of the accelerator module 16 contains a plurality of slits 54 or openings 26 which create a reduction in friction against the fluid flow which sharpens and accelerates the fluid flow the decrease in angle of the slits 54 or openings 26 serves to further sharpen and accelerate the final output each module performs the same function of sharpening and accelerating the nozzle output but each produces different results therefore the modules can be used separately or in any combination which will produce the desired result for the required application depending on the amount of back pressure required back pressure from any module can be diverted to any other module each module can also accommodate a gas liquid or solid fluid depending on the distinct needs and requirements of the function to be performed further the primary and secondary components may be varied to suit different situations for example for some fire fighting situations water would be the primary component with a dry chemical flame retardant being a secondary component and carbon dioxide being another secondary component it will be understood that although the secondary components introduced in the pressure back pressure module.
