NextGen ECS-based on the iORC concept

  • The aircraft environmental control system (ECS) is the largest power consumer (up to 1.5% of the engine power)
     
  • A bleedless engine architecture can reduce the fuel consumption of about 1%, 3%, 4.5% for a regional, midrange and long range aircraft, respectively
     
  • The inverse ORC concept can improve the ECS efficiency up to 800% with respect to the traditional Air Cycle Machine
