An inflator (10) includes a housing (30) defining a chamber (50). An end-burning pyrotechnic charge (60) is in the chamber (50) in the housing (30) for, upon ignition, producing inflation fluid for inflating an inflatable device. The charge (60) has a first predetermined burn rate at a first location along the length of the chamber (50) and a second predetermined burn rate at a second location along the length of the chamber spaced apart from the first location. The second predetermined burn rate is different from the first predetermined burn rate. The inflator (10) includes an initiator (112) for igniting the charge (60), and portions (34, 90, 110) for directing inflation fluid from the chamber (50) to the inflatable device.
