New Concept ECS for Civil Aircraft 2002-01-2421

We propose New Concept ECS as Fig.1, in which named OBNOGS is installed into the ACS, cabin air re-circulation system with re-compressing to mix with bleed air and water vapor recuperation system are performed. Therefore, it gives solutions for safety, cabin comfort and energy saving in future aircraft,
  1. a)
    Increasing safety: Prevention of fuel tank explosion to employ small-sized OBNOGS with re-compressed high pressure air of outflow from cabin
  2. b)
    Increasing cabin comfort: To keep adequate oxygen partial pressure and humidity in the cabin
  3. c)
    Decreasing fuel consumption: Less bleed air and more cabin air re-circulation, which are suitable for future high-bypass jet-engine or all electric aircraft, would bring reduced fuel consumption.
