If you’re a fan of planes, then you’ll love learning about how they’re built. There are things you never knew about the process, from start to finish, and it’s as fascinating as it is full of interesting facts. Here are five fun facts about how airplanes are built:
Lightning strikes are a fact of life for any flying object, and airplanes are no exception. To withstand the force of a lightning strike, airplanes are built with special materials that act as conductors. The metal skin of an airplane is designed to dissipate the electricity from a lightning strike evenly across the surface of the plane so that it doesn’t cause any damage. On top of that, the fuel tanks are surrounded by a special foam that prevents them from igniting in the event of a strike.
If an airplane is struck by lightning, the passengers may feel a jolt or see a flash of light, but the plane itself is designed to withstand the strike and continue flying safely.
The next time you’re looking out the window of an airplane, take a closer look at the glass. You might be surprised to learn that it’s made of three layers. The innermost layer is known as the “scratch layer” and is made of a material that is designed to resist scratching. The middle layer is the “impact layer” and is made of a material that can withstand impact, in case something hits the window. The outermost layer is the “sunshade layer” and is made of a material that blocks out UV rays from the sun.
A material called stretch acrylic is used for airplane windows because it’s lightweight and strong. This material is also used in the production of bulletproof glass. All three layers of the window are held together by a special sealant that keeps the layers from coming apart in the event of an impact or change in pressure.
So, next time you’re looking out the window on a flight, remember that the view is protected by three layers of strong glass!
One of the most important parts of building an airplane is making sure that the engines are up to the task of powering the plane. To do this, engineers put each engine through a series of tests, one of which is known as the “ground run.” This is when the engine is installed on the airplane and runs at full power, while the plane itself is still on the ground.
The ground run allows engineers to make sure that the engine is functioning properly and that it can produce enough power to take the plane off. It also allows them to check for any potential vibrations that could be caused by the engine. After the ground run, the engine is disassembled and inspected to make sure that there are no problems.
Also, an engine test cell, which is a special chamber that simulates the conditions of the flight, is used to test each engine before it’s installed on an airplane. This allows engineers to make sure that the engine will function properly at high altitudes and under different conditions. All of these tests are essential in making sure that the engines are safe and ready to power an airplane.
Gaskets are used in airplanes to seal different parts of the plane, such as the engine and the fuselage. They are made of a variety of materials, but one of the most important is silicone. Silicone has several properties that make it ideal for use in gaskets. It’s heat resistant, so it can withstand the high temperatures that are produced by the engine. It’s also flexible, so it can expand and contract as needed.
Silicone is also very resistant to chemicals, which is important because aircraft fuel is a highly corrosive substance. For instance, the AMS 3195 silicone gasket material is used in a variety of applications, such as fuel tanks and oil pans. This type of gasket can withstand exposure to aviation fuel for long periods without being damaged.
The next time you’re at the airport, take a look at the planes and notice how they all have a sleek, glossy finish. This is because the exterior of an airplane is coated with a special type of paint known as “polyurethane.” This type of paint is different from the paint that is used on other types of vehicles, such as cars and trucks.
Polyurethane paint is much more durable and resistant to weathering. It’s also able to withstand the high speeds and temperatures that are experienced by an airplane during flight.
Building an airplane is a complex and intricate process that involves a lot of different steps. From testing the engines to coating the exterior with paint, each step is essential in making sure that the final product is safe and ready to fly.
