Abstract
An inflation assembly for an evacuation system may comprise a manifold defining an interior volume and a plurality of inflators fluidly coupled to the manifold. Each inflator of the plurality of inflators 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.
Claims14
An inflation assembly for an inflatable device, comprising:
- a manifold defining an interior volume;
- a plurality of inflators fluidly coupled to the manifold, wherein each inflator of the plurality of inflators includes:
- a solid gas generating material;
- and
- an igniter configured to ignite in response to receiving an ignite signal, wherein the solid gas generating material is configured to generate a gas in response to an ignition of the igniter;
- and
- a controller operationally coupled to the plurality of inflators, wherein the controller is configured to:
- identify a desired flowrate to maintain a fan in a turbine fan fluidly coupled to the manifold at a desired rotation per minute;
- identify a desired pressure of the interior volume of the manifold to maintain the desired flowrate;
- determine a time delay between each of a plurality of ignite signals to maintain the desired pressure of the interior volume of the manifold;
- receive an indication of a current pressure within the interior volume of the manifold;
- and
- send a plurality of ignite signals to the plurality of inflators, each ignite signal in the plurality of ignite signals delayed by a respective time delay based on maintaining the desired pressure of the interior volume of the manifold and the current pressure.
