🛫It was introduced to service in 1970 and held its passenger capacity record until the introduction of the Airbus A380 in 2007.

🛫747s have flown more KYthan 3.5 billion people, That is almost half the planet's population.

🛫The 350-400 person 747 once carried 1087 people at once during the Operation Solomon evacuation, Israel.

🛫It takes 90 gallons of paint to paint a 747.

🛫Boeing has modified around 15 of their 1500 747 palnes for special purposes.

🛫The engine fan diameter is almost as girthy as a B-29 bomber.

🛫A Boeing 747 aircraft held the passenger capacity record for 38 years.

🛫Because of its distinctive upper hump, it is one of the most recognizable aircraft in the world.

🛫Total electricity capacity of a 747-8 can power up to 4,80,000 32 inch flat screen TVs.

🛫Its original nickname is “Jumbo Jet”.

🛫If the distance covered by the entire fleet of Boeing 747s is added up, you could make 75,000 trips to the moon and back.

🛫A monocoque structure uses its outer shell to support stresses and loads applied to it, whereas a semi-monocoque structure has an internal "skeleton" of supports and braces to keep its shape rigid and strong. 🛫The vast majority of pressurized aircraft are semimonocoque to help distribute stresses equally along the fuselage during flight. 🛫However, some helicopters use monocoque structure to maximize internal space in the flight compartment. 🛫Monocoque fuselage has its skin holding the skeleton structure together while the semi-monocoque has both the skin and the skeleton holding together. 🛫Semi-monocoque also has "stringers" running horizontally down the plane to help hold the frame together. 🛫The monocoque fuselage also cannot be used for airframes after a certain size (small aircraft with single engine), but the semi-monocoque has been used from single piston engines to commercial airliners. 🛫A monocoque design would also have ...

🛩️A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, combustion chamber is fed high pressure air by the compression system. 🛩️The combustor then heats this air at constant pressure. After heating, air passes from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the air is directly fed to the nozzle. 𝐀𝐧𝐧𝐮𝐥𝐚𝐫 𝐓𝐲𝐩𝐞 ✈️The most commonly used type of combustor is the fully annular combustor. Annular combustors do away with the separate combustion zones and simply have a continuous liner and casing in a ring. There are many advantages to annular combustors, including more uniform combustion, shorter size, lighter, and less surface area. Annular combustors tend to have very uniform exit temperatures. They also have the lowest pressure drop of the three...

Five Major Stresses 🛩️Aircraft structural members are designed to carry a load or to resist stress. Aircraft parts must be planned to carry the load to be imposed upon it. 🛩️The term stress is often used interchangeably with the word “strain.” They are not the same thing. External loads or forces cause stress. Stress is a material’s internal resistance, or counterforce, that opposes deformation. The degree of deformation of a material is strain. When a material is subjected to a load or force, that material is deformed, regardless of how strong the material is or how light the load is. 🛩️Here 5 major stresses to which aircraft is subjected ✳️Tension ✳️Compression ✳️Torsion ✳️Shear ✳️Bending ✈️Tension is the stress that resists a force that tends to pull something apart. The engine pulls the aircraft forward, but air resistance tries to hold it back. The result is tension, which stretches the aircraft. The tensile strength of a material is measured in pounds per square inc...
