Concorde had a cruising speed that was 2.31 times higher than Boeing 747, and a lift-to-drag ratio that was almost the same times lower (2.36). So, every second Concorde had to burn about 2.36 times more fuel per ton of aircraft compared to 747, but it reaches the destination 2.31 times faster. All in all, the fuel consumption during the cruising phase of the flight was comparable. Well, Concorde had a horrible fuel economy during takeoff, so overall it was pretty bad compared with the 747. But 50 years have passed since the Concorde was designed. Both computational fluid dynamics algorithms and computing power have made tremendous progress. It's quite likely Ouverture will have a much better fuel economy than Concorde, if only for the fact that it will use turbofan rather than turbojet. |
