    摘要： A Controlled Unaided Surge and Purge Suppressor for firearms uses the blast and plume characteristics inherent to the ballistic discharge process to develop a new two-step controlled surge and purge system centered around advanced mixer-ejector concepts. The blast surge noise is reduced by controlling the flow expansion, and the flash effects are reduced by controlling inflow and outflow gas purges. This is a C-I-P application. In the preferred C-I-P embodiment, the blast surge is mitigated via a slotted mixer nozzle; a first expansion chamber; a generally “wagon-wheel” shaped blast baffle with a vent hole; a series of alternating baffles, with vent holes, strategically located along the suppressor's inner wall surface; a second expansion chamber; and an exit opening. This preferred C-I-P embodiment contains no “outside” vent holes (i.e., throughbores) which extend through the suppressor's outer or longitudinal wall. Instead of ingesting ambient air through such throughbores and mixing that air with the muzzle gases, as shown in the parent application, the preferred C-I-P embodiment ingests and mixes chamber gases and contaminants with the muzzle gases while allowing fluid flow through and out the suppressor. It too though can control or eliminate the Mach disk.

    摘要： A Controlled Unaided Surge and Purge (CUSPS) suppressor for firearms uses the blast and plume characteristics inherent to the ballistic discharge process to develop a new two-step controlled surge and purge system centered around advanced mixer-ejector concepts. The blast surge noise is reduced by controlling the flow expansion, and the flash effects are reduced by controlling inflow and outflow gas purges. In the preferred embodiment, suppressor vent holes are convergently contoured to better reduce the blast surge. Preferably a two-stage supersonic mixer/ejector system, in combination with adjacent vent holes in the suppressor housing and a divergent entrance nozzle, is used to control or eliminate the external Mach disk, while rapidly mixing and diluting the propellant with purged gases. A diffuser downstream of the mixer/ejector system further increases ejector performance and pumping. The pumped gases are used to self-clean and cool the CUSPS suppressor.
