An aspirator system (100; 200; 804) for inflating an inflatable evacuation device (142; 806) includes an aspirator body (118; 218) having a plurality of flapper doors (106A - 106B; 206A - 206B) configured to open to allow intake of atmospheric gas. The aspirator system (100; 200; 804) also includes an aspirator barrel (102; 202) connecting the aspirator body (118; 218) to the inflatable evacuation device (142; 806), having connected inflation chambers (120; 220) wrapping around a circumference of the aspirator barrel (102; 202) and arranged along a length of the aspirator barrel, and being configured to provide an aspirator barrel chamber (112; 212) for guiding the atmospheric gas to the inflatable evacuation device (142; 806) when the aspirator barrel (102; 202) is inflated. The aspirator system (100; 200; 804) also includes a showerhead nozzle (104; 204) connected to the connected inflation chambers (120; 220), configured to direct high-pressure gas to inflate the aspirator barrel (102; 202) and compel intake of atmospheric gas through the plurality of flapper doors (106A - 106B; 206A - 206B), to inflate the inflatable evacuation device (142; 806).
