One thing to consider is that you save a lot of weight on noise insulation. The wavy edges on the back of many new jet engines make the engines about 2% less efficient, but they let the plane save on enough weight to more than make up for it. Electric engines are probably about 20db quieter than equivalent power jet engines, so that can claw back some of the lost range. |
