Engineering excellence: Springs in safety-critical aviation applications

08 January 2024

In the intricate realm of aerospace engineering, where precision is paramount and safety is sacrosanct, every component plays an indispensable role in ensuring the integrity of the final product. In this feature, we explore the role of springs in safety-critical aviation applications, with a particular focus on a set of springs that have defied the odds, completing an astounding 10,000,000 cycles, while still appearing as immaculate as the day they were crafted.

The crucial role of springs in aviation safety 
Passengers who board private jets, commercial airliners, and defence systems entrust their safety and comfort to the aerospace industry. Safety permeates every facet of aviation, extending even to the smallest components, such as springs

Within aviation applications, springs serve a multitude of functions, from supporting landing gear to regulating wing flaps. Yet, one of their most vital roles lies in ensuring the safety and functionality of aircraft doors. 

Aircraft doors, regardless of whether they belong to private jets, commercial airliners, or defence vehicles, must adhere to stringent safety and reliability standards. These doors endure a myriad of operational conditions, from rapid pressure fluctuations to extreme temperature swings, and mechanical stresses during take-off and landing. Consequently, the springs that maintain the structural integrity of these doors must undergo meticulous design and precision manufacturing.
