Currently the world's largest airplane is Airbus A380, can carry 525 people in a normal three-class configuration. It can travel nonstop 15,700 kilometers (8,500 nmi; 9,800 mi), at a speed of Mach 0.85 (about 900 Km/h or 560 mph; 490 kn at cursing altitude). To carry twice as many passengers and fly the same distance with the similar performance or better can achieved by joining the two same types of airplanes in the rear to front, (FIG. 1), or rear to rear (FIG. 2), can have the equivalent or better effect, and have similar or better performance than keep on building larger, fatter, airplanes such as A380. For example, Airbus, A350 can carry 350 passengers in a three-class setting, if the two A350s are jointed, it can carry, 700 passengers instead of only 350. This will work on other makers with the two same types of large airplanes. |
