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

该项目将新的高强度不锈钢材料应用到具有挑战性的起落架环境中，主要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)。起落架目前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，主要由腐蚀推动的大修成本是起落架维护成本的主要贡献者之一。腐蚀已被确定为在目前的飞机计划中将TBO限制在10年内的关键因素，也是大约三分之一的大修维修费用。研究表明，将总寿命从10年增加到14年将使起落架每架飞机的拥有成本降低约10美元/FH。该项目是与Messier-Dowty Ltd在起落架设计材料需求方面的合作，Carpenter Technology Corp在耐腐蚀钢方面的合作，以及谢菲尔德AMRC在先进制造和测试能力方面的合作。空中客车公司将负责该技术的性能要求、集成、认证和测试要求方面。

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.
