Going that fast requires significantly more energy. You start to worry about things like the cross section of the aircraft (which is why fast plane commonly have knife-edge wings) and smooth airflow over the fuselage. One of the advantages of the composite construction being used by Boom is you don't have those thousands of rivets sticking out. And panel gaps. Which is why the 787 is as fuel-efficient as it is compared to traditional aluminum bodied aircraft. |
