Improved Solid-State Hydrogen Gas Generator

nbsp; nbsp; nbsp;Deployable aerodynamic decelerators are an enabling technology for missions to planets and moons with atmospheres as well as for returning payloads to Earth.nbsp; These decelerators require a gas source for inflation, and the objective is to further advance solid-state hydrogen gas generators.nbsp; nbsp; nbsp;In Phase I, Anasphere demonstrated the adaptation of an improved hydrogen gas generator to NASA applications.nbsp; The new generator is superior in terms of mass efficiency, durability, cost, and form factor flexibility compared to Anaspherersquo;s earlier generators.nbsp; Gas purity continues to be excellent (gt;99%).nbsp; Generators up to a capacity of 426 normal liters were tested.nbsp;nbsp; nbsp; nbsp;Phase II work will involve optimizing the construction of the generators for the Hypersonic Inflatable Aerodynamic Decelerator (HIAD) application, improving particulate removal and cooling methods, specifically addressing NASA Standard Initiator (NSI) integration, conducting more and larger tests, and conducting environmental testing.
