A mini review on Aerospace Engineering: Lubrication Challenges and Innovation Tribology

The success of aircraft engineering is based on tribology, the study and engineering of interacting surfaces in relative motion. Effective lubrication reduces friction and wear in everything from hypersonic re-entry vehicles to sophisticated satellite mechanisms, assuring smooth operation, prolonged lifespan, and, ultimately, mission success and people safety. The high conditions witnessed in the aircraft environment, on the other hand, pose formidable hurdles to conventional lubricating systems. This research goes into the complicated interplay of tribology and aeronautical engineering by painstakingly analyzing the lubrication issues posed by harsh working conditions, stringent material constraints, and limited substitute alternatives. It then delves into tribologists’ novel solutions, such as solid lubricants, surface coatings, sophisticated monitoring systems, and bio-inspired lubricants. The research demonstrates how tribology continues to push the boundaries of aerospace engineering by examining these achievements.
