The Protocol Programme: Advanced Ground operations through Landing Gear Enhancements and The Corrosion Resistant Steel Project (AGILE-CREST)

该项目将在具有挑战性的起落架环境中应用新型高强度不锈钢材料，其关键目标是最大限度地减少与腐蚀相关的维护，并大大延长大修间隔时间（TBO）。如今，起落架是飞机机队管理运营成本的重要组成部分。腐蚀导致运营中断，导致飞机延误和取消。航空公司已经证实，主要由腐蚀引起的大修成本是起落架维护成本的主要来源之一。腐蚀已被确定为限制现有飞机项目TBO为10年的关键因素，并且约占大修维修费用的三分之一。研究表明，将TBO从10年增加到14年，每架飞机的起落架拥有成本将降低约10美元/FH。该项目与梅西耶-道蒂公司合作，负责起落架设计材料要求，卡彭特技术公司负责耐腐蚀钢，谢菲尔德的AMRC负责先进制造和测试能力。空客将负责该技术的性能要求、集成、认证和测试要求方面的工作。

This project will apply new high strength stainless steel materials to the challenging Landing Gear environment with the key objective to minimise corrosion related maintenance and enable greatly extended Time between overhaul (TBO).Landing Gear is today a significant contributor to the operational cost of the management of an Aircraft fleet. Corrosion contributes to operational interrupts leading to delays and cancellations of Aircraft. Airlines have confirmed that overhaul cost, largely driven by corrosion, is one of the major contributors to the maintenance cost of Landing Gear. Corrosion has been identified as the key factor limiting TBO to 10 years on current aircraft programs and also around one third of the overhaul repair bill. Studies have shown that increasing the TBO from 10 to 14 years would reduce Landing Gear cost of ownership by around 10$/FH per aircraft.The project is collaboration with Messier-Dowty Ltd for landing gear design material requirements, Carpenter Technology Corp for corrosion resistant steels and the AMRC in Sheffield for advanced manufacturing and test capability. Airbus will be responsible for performance Requirements, Integration, Certification and test requirements aspects of the Technology.
