Concept design of an ultra low noise, fuel efficient aircraft

The concept aircraft SAX-40 (Silent Aircraft eXperimental) is a result of an iterative design process (SAX-01 to SAX-40) to achieve low noise and improved fuel burn.

A computer-generated image of the SAX-40 conceptual aircraft design

We predict:

  • 149 passenger-miles per UK gallon of fuel (compared with about 120 for the best current aircraft in this range and size). This is equivalent to the Toyota Prius Hybrid car carrying two passengers.
  • A noise of 63 dBA outside airport perimeter. This is some 25dB quieter than current aircraft.
