1. A gas-generating device comprising:
- a plurality of gas-generant grains arranged in a longitudinally extending stack and constrained to a longitudinally stacked configuration by a frame; and
a plurality of retention plates coupled to the frame and fixed relative to the frame, each retention plate of the plurality positioned between one adjacent gas-generant grain of the plurality of gas generant grains and another adjacent gas-generant grain of the plurality of gas-generant grains in the longitudinally extending stack.

Abstract
Gas-generating devices with grain-retention structures and related methods and systems are described. In particular, gas-generating devices having at least one retention structure fixed to a frame and positioned between adjacent gas-generant grains arranged in a longitudinal stack. Fire suppression systems comprising such gas-generating devices are also described. Additionally, methods of manufacturing gas-generating devices, as well as methods of generating a gas and methods of suppressing a fire utilizing such gas-generating devices are described.

10. A gas-generating device comprising:
-
longitudinally stacked gas-generant grains; a frame constraining the gas-generant grains to a longitudinally stacked configuration; and retention structures coupled to the frame, each retention structure positioned between adjacent gas-generant grains, the retention structures sized and configured to remain fixed to the frame and constrain the longitudinal position of the adjacent gas-generant grains relative to the frame as the adjacent gas-generant grains in the longitudinal stack generate gas. - View Dependent Claims (11, 12)

19. A method of generating a gas, the method comprising:
-
combusting a plurality of longitudinally stacked gas-generant grains to generate a gas; restricting lateral movement of the plurality of longitudinally stacked gas-generant grains during combustion with a frame structure; and restricting longitudinal movement of at least some of the plurality of longitudinally stacked gas-generant grains during combustion by maintaining retaining members between adjacent gas-generant grains of the plurality of longitudinally stacked gas-generant grains and maintaining the retaining members fixed relative to the frame structure during combustion. - View Dependent Claims (20)
