Understanding How Torque Links Function

When it comes to aircraft landing gear, one critical component that ensures a smooth and controlled touchdown is the torque link. Also known as a torsion link, the torque link serves to manage the impact forces and vibrations faced by the airframe during landing to maintain safety and integrity. In this blog, we will delve into the concept of torque links, their working principles, and their significance in aircraft operations.

The landing gear of an aircraft plays a vital role in providing stability, support, and shock absorption during takeoff, landing, and taxiing operations. A typical gear assembly will consist of several components, including the main landing gear, nose gear, and any associated mechanisms. One of the key components within the landing gear system is the torque link.

In its most basic form, the torque or torsion link is a structural element that acts as a shock absorber and a physical link between the landing gear strut and the aircraft structure. Its primary purpose is to absorb the impact forces generated during landing, preventing excessive loads from reaching the airframe where damage can cause various issues and hazards. The torque link achieves this through its unique design and operational characteristics.

The working principle of a torque link is based on torsional or twisting deformation. The link itself consists of a hollow cylindrical structure, typically made of high-strength materials such as steel or titanium that provide an optimal strength-to-weight ratio. The link is connected at one end to the landing gear strut and at the other end to the aircraft structure with the help of bushings, bolts, and pins.

When an aircraft is touching down and its landing gear makes contact with the runway surface, impact forces are transmitted through the wheels and landing gear strut to the torque link. These forces cause the link to undergo torsional deformation, causing it to twist along its longitudinal axis. This twisting motion absorbs and dissipates the energy of landing, protecting the airframe and reducing the risk of structural damage.

The torque link's ability to absorb and dampen vibrations is crucial for ensuring a comfortable landing experience for passengers while protecting the integrity of the aircraft for overall safety. By effectively managing impact forces, the torque link minimizes the stress and strain exerted on the landing gear and airframe, enhancing the overall longevity of the aircraft.

While primarily serving as a shock absorber, the torque link also provides stability and control during landing. It specifically helps maintain the alignment and geometry of landing gear assemblies, ensuring proper ground contact while preventing lateral deviations. This promotes a smooth and balanced touchdown process, reducing the risk of veering off the runway or experiencing excessive yaw or roll movements.

It is worth noting that the exact design and characteristics of torque links can vary depending on the specific aircraft and its landing gear configuration. Factors such as aircraft size, weight, and intended use all influence the selection and design of torque links. Recent advancements in materials and manufacturing techniques have also led to the development of lightweight and high-strength torque links which contribute to overall weight reduction, improved fuel efficiency, and enhanced performance of modern aircraft.

With the various roles that torque links serve in standard aircraft operations, one can see how important it is to ensure that such assemblies are well maintained and cared for to ensure safety.
