dc.description.abstractZero-g validation of a microwave powered Plasma Pyrolysis Assembly (PPA) is underway. The PPA recovers 75% of the hydrogen from methane which is produced by a Sabatier reactor. PPA efficacy has been demonstrated by extensive ground testing. To verify that it will function under zero-g conditions, computer modeling has been performed and preparations for zero-g parabolic flight tests are proceeding. The results of computer modeling are presented, and the design, fabrication, and preparation for the PPA zero-g flight experiment are covered. Details related to meeting zero-g corporation flight requirements are presented. Specific challenges included hazardous (explosive) gas use and safe accommodation / disposal aboard an aircraft. Pressurized gas cylinder handling and containment, zero-g compatible cooling system implementation, vacuum system and microwave system designs and built-in safety elements are discussed.en_US
