Abstract:
1. A gas generator comprising: an elongate body having a first end and a second end and at least one gas exit aperture; a perforate inner wall positioned within said body, said inner wall forming a gas generant chamber; a perforate baffle tube positioned within said body and outwardly of said perforate inner wall for cooling of gases formed upon activation of said gas generator, said baffle tube containing a first inner baffle wall and a second outer baffle wall structurally fixed to said first inner baffle wall thereby forming a first plenum between said perforate inner wall and said first inner baffle wall, said first plenum fluidly communicating with said gas generant chamber upon gas generator activation; and a second plenum formed between said inner baffle wall and said-outer baffle wall, said second plenum in fluid communication with said first plenum and said at least one gas exit aperture upon gas generator activation, wherein gases produced upon activation of said gas generator exit said gas generant chamber and traverse said first plenum to one end of said body, and then traverse said second plenum to the other end of said body, and then exit said gas generator through said at least one gas exit aperture.
