<p>An amphibious large aircraft without airstairs is provided. The fuselage (7) of the amphibious large aircraft is flat,and the shape of its bottom is rectangular. The longitudinal cross-section of the fuselage has a shape of the cross-section of a wing, so the lift can be generated by the fuselage during flight, and the flight efficiency is increased by 30-40%. The fuselage has only one floor, wherein the passenger cabin (6) is set in the front of the fuselage, and the cargo hold (21) is set in the rear. The wings (8) are suspended towards two sides from upper side of the fuselage. A jet engine (30) is mounted above the rear of the fuselage and adjacent to the tail wing. Because landing gears (4, 9) can be lifted vertically and the landing gear wells (3, 10) mounted in the fuselage are provided with fore-and-aft sliding doors (32, 33), the fuselage can stop close to the ground. It is no need for the passenger to go on and off the aircraft via the airstairs and escape from the aircraft via the inflator slide in an emergency. It can be more convenient for the cargo to enter or exit the aircraft when the aircraft is used as a freight aircraft. Because the fuselage is flat, the gliding capability and the ground effect of the aircraft are better, and the aircraft can takeoff, land and cruise on the wide water. The full-length, wingspan and height of the aircraft are all reduced by 25%-30% compared with the current aircraft of the same scale, thus the floor space and the investment of the manufacturer, the maintenance factory, the garage and the aerodrome are all reduced.</p> |
