Aircraft struts are a type of landing gear that supports the weight of the aircraft on the ground. They work by absorbing and distributing the load evenly to prevent damage to the aircraft structure and tires. Without the use of struts, the aircraft would sit directly on the wheels, creating a high-stress situation that could lead to failure.

Most aircraft struts are made from aluminum, titanium, or steel and consist of various components, including the piston, cylinder, and upper and lower strut bearings. These components work together to provide maximum support and flexibility while the aircraft is in motion.

Tips for Proper Maintenance and Replacement of Strut Parts

When to Replace Strut Components

The timing of strut component replacement will depend on several factors, including the manufacturer’s recommendations and the frequency of use. It’s essential to follow the manufacturer’s guidelines and schedule regular maintenance to ensure maximum safety and reliability.

The importance of aircraft struts cannot be overstated. As mentioned earlier, the struts serve as a support beam to bear the weight of the aircraft on the ground. But, they also play a significant role in providing shock absorption and stability while the aircraft is in motion. Properly functioning struts ensure that the aircraft is stable during takeoff and landing, reducing the risk of accidents.

In addition to providing support and stability, aircraft struts also help to absorb shock during landing. This is especially important when landing on uneven terrain, as the struts can help to prevent damage to the aircraft and its passengers. Struts also help to distribute the weight of the aircraft more evenly, reducing the stress on individual components and increasing the lifespan of the aircraft.

  • Fixed Struts: These are the most basic type of aircraft strut and are often found on smaller aircraft. They are simple and reliable, but lack the flexibility of other types of struts.

  • Retractable Struts: These struts can be retracted into the aircraft during flight, reducing drag and improving fuel efficiency. They are often found on larger aircraft and are more complex than fixed struts.

  • Oleo Struts: These struts use a hydraulic system to provide shock absorption during landing. They are commonly found on military aircraft and larger commercial planes.

  • Nosewheel Struts: These struts are located at the front of the aircraft and support the weight of the nosewheel. They are essential for steering and stability during takeoff and landing.

  • Main Gear Struts: These struts support the weight of the main landing gear and are critical for providing stability during takeoff and landing. They are often the largest and most complex type of strut.

The type of strut you need will depend on various factors, including the type of aircraft, the weight of the aircraft, and the terrain you’ll be landing on.

  • Piston seals: These seals help to prevent hydraulic fluid from leaking out of the strut assembly.

  • Pressure tubes and fittings: These tubes and fittings are used to transfer hydraulic fluid between different parts of the strut assembly.

  • Upper and lower strut bearings: These bearings help to reduce friction between the different parts of the strut assembly, improving flexibility and reducing wear and tear.

  • Bolts and nuts: These fasteners are used to secure the different parts of the strut assembly together.

  • Mounting hardware: This hardware is used to attach the strut assembly to the aircraft.

Understanding these components can help you to select the right strut parts for your aircraft and ensure that you have everything you need for proper installation and maintenance. Regular maintenance and inspection of aircraft struts are essential to ensure their proper functioning and longevity, which is critical for the safety of the aircraft and its passengers.
