The differences between Airbus and Boeing aircraft are:
1. Different appearance
The boarding gates of Airbus and Boeing are different, and they are each patented. The doors of Airbus slide to the side and open like those of buses, while the doors of Boeing open outward like ordinary doors.
2. The systems are different
The Airbus flight control system is a cable for fly-by-wire control, while Boeing is a cable pulley transmission rod for mechanical control; Boeing has a cable in the cockpit Airbus does not have a steering wheel. Airbus has a side stick on the side like a joystick on a game console.
3. Different advantages and disadvantages
The controllability, stability and maneuverability of Boeing aircraft are worse than those of Airbus; while the reliability of Airbus aircraft is poor and vulnerable to lightning strikes and electromagnetic pulse interference. It is not as good as Boeing aircraft. Good.
Design features of the Boeing 737:
1. Structural design
Boeing 737 uses as many parts as possible in the initial design to reduce production costs and price. The engine nacelle is mounted on a 35-half wingspan. Although the engine nacelle is very close to the ground, based on the streamline analysis of the front wheel lift during take-off and landing, it is difficult for foreign objects to enter the engine inlet.
2. Wing design
The Boeing 737 wing adopts a cantilever mid-wing. Since the aircraft has a short range, low cruising speed and altitude, it adopts a large wing load (500 kg/m2) and a small sweep angle. The aspect ratio is 8.83, the 1/4 chord sweep angle is 25°, and the average relative thickness is 12.89.
3. Power design
Boeing 737 has two engines suspended under the wings. The earliest models of the 737-100/-200 initially used turbojet engines. The 737-200 can be equipped with low-bypass-ratio turbofan engines such as the JT8D, with a single thrust of 71.2 kN (7260 kg).
