How many tons is a Boeing 737?

The empty weight of Boeing 737 is 3 1479 kg, the maximum load capacity is 16 148 g, the maximum takeoff weight is 56472 kg, and the maximum landing weight is 5 17 10 kg.

Boeing 737-700: The maximum takeoff weight is 90 10 kg.

Boeing 737 is mainly aimed at the demand of short-haul routes. It is reliable, simple and economical in operation and maintenance, but it is not suitable for long-distance flight. According to the project start-up time and technological advancement, it is divided into traditional 737 and new generation 737.

Boeing 737 is generally safe. Traditional 737 includes 737-100/-200; 737-300/-400/-500, and the new generation 737 includes 737-600/-700/-800/-900.

Compared with the early 737, the Boeing 737-700 has improved the wing and engine, and improved the fuel capacity, combustion efficiency, cruising speed and range. The chord length of each wing increased by 20 inches, the wingspan increased by about 16 feet, and the total wing area increased by 25%, reaching 1340 square feet.

This increased the fuel capacity by 30% to 6875 gallons; Its cruising speed reached Mach 0.78. Boeing 737-700 has a range of about 3,200 nautical miles, 900 nautical miles more than the early Boeing 737, enabling it to fly across continents.

In terms of engine, Boeing 737-700 originally used CFM 56-7, a joint venture between General Electric and French necma company, and its thrust was 10% higher than that of CFM 56-3C engine of early Boeing 737. In April 2009, the engine of Boeing 737-700 was replaced by CFM 56-7BE, and the fuel consumption was reduced by 2%.

What are the characteristics of Boeing 737 series aircraft in structural design?

Boeing 737 used as many parts and components as possible in its initial design to reduce the production cost and price. The engine nacelle is installed at 35% of the half span. Although the engine nacelle is close to the ground, according to the streamline analysis of the front wheel lift when landing, foreign objects are not easy to enter the engine intake. The fuselage adopts aluminum alloy semi-hard shell structure.

Different from Boeing aircraft in the past, grid stiffeners are glued in the fuselage skin, and the skin at each row of connectors is double-layered to improve the fatigue characteristics of the fuselage and form a grid crack arrest zone, and these squares are used to "limit" the possible crack propagation.

The landing gear adopts hydraulic retractable front three points, which can be automatically lowered by gravity in an emergency. The front cargo hold and the rear cargo hold are under the front floor and the rear floor of the wing. Boeing 737 has established a double cockpit operation mode from the beginning of design.

What aero-engine does Boeing 737-800 use?

Boeing 737-800 has a maximum passenger capacity of 189 passengers and is equipped with CFM-56 engine. It is worth mentioning that airlines are free to choose and replace engines from other suppliers. It is reported that CFM engine is jointly manufactured by General Electric Company and Safran Group of France. Let's take a look at two giant companies:

American General Electric Company: It is the largest diversified service company in the world. From aircraft engines and power generation equipment to financial services, from plastics for medical imaging and TV programs, the history of General Electric Company can be traced back to Thomas Edison, who founded Edison Electric Company on 1878. 1892, Edison Electric Company and Thomson-Houston Electric Company merged to form General Electric Company. The technology of electrical products of General Electric Company is relatively mature, and there are many kinds of products. In addition to producing consumer appliances and industrial electrical equipment, it is also a large arms contractor, manufacturing aerospace instruments, pilot navigation systems for jet planes, multi-warhead ballistic missile systems, radar and space flight systems. For example, the world-famous Atlas rocket and Raytheon rocket can carry atomic bombs and hydrogen bombs, both of which are produced by this company.

Its subsidiaries: General Electric Capital, General Electric Aviation Financial Services, General Electric Commercial Finance, General Electric Energy Financial Services, General Electric Finance, General Electric Fund, General Electric Technical Facilities, General Electric Aviation, General Electric Enterprise Solutions, General Electric Medical Services, General Electric Transportation, General Electric Energy Facilities, General Electric Water Treatment, General Electric Oil and Gas, General Electric Energy, General Electric Consumers and Industries, General Electric Equipment, General Electric Lighting and General Electric.

Safran Group, France: It is a world-class manufacturer of aero-engines and equipment, providing high-tech solutions to customers all over the world for aircraft, helicopters, missiles, aviation propellers and their equipment in civil and military markets. Safran Group designs, develops, produces and sells aviation propulsion systems and equipment on a global scale, and provides maintenance and overhaul services for them. Safran Group has participated in many large-scale aerospace projects in the world alone or through cooperation with other companies.
