Results from the Plasma Pyrolysis Assembly (PPA) Zero-g Flight Experiment

Results of zero-g validation testing of a microwave powered Plasma Pyrolysis Assembly (PPA) are presented. 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 and zero-g parabolic flight tests have been performed. 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.
