    Case Study of the Benefits of Collaboration Between Aircraft and Space
    (2024 International Conference on Environmnetal Systems, 2024-07-21) Schuster, Ashley; Woldemariam, Beakal; Campbell, Andrew; Litton, Kevin; Myers, Casey; Hoang, Thao; Diner, Joe; Monson, Timothy
    Only 100 years ago, taking a flight across the ocean was as unattainable to much of the world as traveling to space seems today. However, the airline industry underwent a commercial revolution that made air travel a staple in the global economy. That growth was remarkably similar to the rapid change that the space industry is seeing today. As a supplier to both commercial aircraft and space platforms, Collins Aerospace, an RTX business, has taken advantage of its broad expertise and performed cross-discipline collaboration to bring commercial aircraft and space lessons learned together for use in the commercialization of space. This paper discusses the findings from work completed by Collins Aerospace Space Systems and Interiors that looked at one area where these business units directly overlap - the commode. The work aimed to determine what differences exist between the space systems and aircraft approaches to the commode and how these differences could be leveraged to optimize the design and execution of the commode for the space market. The key outputs to be discussed include findings from the exercise and the implementation of the findings on a new commode architecture.

    NextGen Oxygen Generating Assembly (OGA) for Commercial Aerospace
    (2024 International Conference on Environmnetal Systems, 2024-07-21) Myles, Timothy; Campbell, Andrew; Blaskewicz, Luke; Miller, Christopher
    The current Oxygen Generating Assembly (OGA) on the International Space Station (ISS) utilizes a large variety of custom components including a cathode feed electrolyzer, rotary separator, containment dome and use of dual seals to mitigate the risk of hydrogen leakage. While this system has operated for decades on station, the heavy use of custom-made components makes it prohibitively expensive for future commercial aerospace applications. This paper describes the next generation (NextGen) OGA system utilizing commercially available hardware. Major changes to the system architecture include the switch from a cathode feed electrolyzer to an anode feed. While this presents challenges by adding an additional phase separator effective in micro-gravity, recent investment in electrolyzer technology for supporting clean energy applications has caused a surge in commercially available stacks with proven reliability. These stacks are almost exclusively anode feed, sparking an interest in re-examining an anode feed based OGA. Despite the need for an additional separator, recent advancements in separation technology help to mitigate the risk and cost, with inexpensive commercial separators offering potential alternatives to custom rotary separators. In addition to switching to anode feed, the NextGen system examines an alternative hydrogen safety approach which eliminates the use of a dome and dual seals, replacing them with a ventilation and monitoring strategy and drawing on lessons learned from years of operating the OGA system on ISS.
