Aircraft extrusions are made through a process of extrusion. This type of manufacturing is used to create products with a consistent cross-sectional profile. In the aerospace industry, aircraft extrusions are often used in the manufacture of structural components. Learn more about them in this article!
What are aircraft extrusions?
An aircraft extrusion is a metal component that has been formed into a specific shape using a die. Extrusions are used in a variety of applications, including structural supports, window frames, and door seals. One of the benefits of using extrusions is that they can be produced in a range of shapes and sizes, making them ideal for custom applications.
In addition, extrusions are often less expensive than other types of metal components. As a result, aircraft manufacturers often rely on extrusions to create parts that are both strong and cost-effective.
The benefits of using aluminum for aircraft extrusions
Aluminum is a versatile metal that has a number of advantages for use in aircraft extrusions. It is strong yet lightweight, making it ideal for use in airplanes and other aircraft. Aluminum also has great resistance to corrosion, meaning it can withstand the rigors of flying without deteriorating.
In addition, aluminum is easy to work with and can be molded into a variety of shapes and sizes. As a result, it is an excellent choice for use in aircraft extrusions.
The different shapes and sizes of aircraft extrusions
Aircraft extrusions come in a variety of shapes and sizes, depending on the aircraft design and the purpose of the extrusion.
The most common shapes are round, rectangular, and oval. Round extrusions are used for structural purposes, such as attaching wings to the fuselage. Rectangular extrusions are used for aerodynamic purposes, such as providing a smooth surface for air to flow over. Oval extrusions are often used for both structural and aerodynamic purposes.
The size of an aircraft extrusion also varies depending on the aircraft design. The width of an extrusion may be anything from a few inches to several feet, and the length may be anything from a few feet to several miles.
In some cases, multiple extrusions may be combined to form a single piece, such as when two rectangular extrusions are joined together to form a T-shaped piece. No matter what the shape or size, all aircraft extrusions play an important role in the overall design of the aircraft.
The extrusion process – manual vs. automated
The extrusion process is a manufacturing method that involves forcing Raw material through a die to create a desired shape. The Raw material is first heated until it becomes pliable, and then it is forced through the die using high-pressure hydraulic rams.
There are two main types of extrusion processes: manual and automated. Manual extrusion requires an operator to load the Raw material into the machine and operate the hydraulic rams. This type of extrusion is typically used for simple shapes that do not require precise tolerances.
Automated extrusion, on the other hand, uses robotics to load the Raw material and operate the machine. This type of process is more expensive but it allows for greater precision and repeatability. In addition, automated extrusion can be used to create complex shapes that would be difficult or impossible to produce using manual methods.
Despite the additional cost, automated extrusion is often the best choice for applications that require high precision or complex geometry.
The applications of aircraft extrusions in the aerospace industry
In the aerospace industry, aircraft extrusions are used in a variety of ways. One common application is in the production of fuselage frames. Extruded aluminum alloys are often used for this purpose due to their high strength-to-weight ratio.
Another common use for aircraft extrusions is in the construction of wing spars. Spars are the main structural element of a wing, and they must be strong enough to withstand the immense loads imposed during flight. Extruded aluminum alloys are often used for spars due to their high strength and good fatigue resistance.
In addition, aircraft extrusions are also used in the construction of landing gear struts, control surfaces, and other components. Thanks to their versatility and strength, aircraft extrusions play a vital role in the aerospace industry.
