Goals:Goals:
• Cabin vibrations below 0,05 g corresponding to jet smooth ride comfort, for the same flight regime area.
• Acoustic footprint areas reduced between 30% and 50% depending on the flight condition
• Cabin noise levels below 75 dBA, similar to airliner cabins, for normal cruise
• A reduction of fuel consumption by 6 % in high speed flight.
