Abstract
An inflation system for an evacuation system may comprise an inflator and a controller operationally coupled to the inflator. The inflator may include a solid gas generating material and an igniter configured to ignite in response to receiving an ignite signal. The solid gas generating material may be configured to generate a gas in response to an ignition of the igniter. The controller may be configured to send the ignite signal to the inflator.
Claims18
An inflation system for an inflatable, comprising:
- a first inflator including:
- a solid gas generating material;
- and
- an igniter configured to ignite in response to receiving a first ignite signal, wherein the solid gas generating material is configured to generate a gas in response to an ignition of the igniter;
- a first panel located in an interior volume of the inflatable, wherein the first panel comprises a plurality of panel openings, wherein the first inflator is located through a first opening of the plurality of panel openings in the first panel, and wherein other openings in the plurality of openings allow the gas to flow through the first panel;
- a second panel located in the interior volume of the inflatable, wherein the second panel forms a sealing interface such that the gas is prevented from flowing through the second panel;
- and
- a controller operationally coupled to the first inflator and configured to send the first ignite signal to the first inflator.
