An LRU is an essential support item which is removed and replaced at the field level to restore the end item to an operational ready condition. Conversely, a non-LRU is a part, component, or assembly used in the repair of an LRU / LLRU, when the LRU has failed and has been removed from the end item for repair.

2017年12月28日 · 航线可更换单元 ( LRU，Line Replaceable Unit)，是飞机在航线维修期间，可以方便地使用标准工具在飞机上更换的产品（包括零组件、设备、结构件等）。 LRU 通常具有以下特征： 在航线维修现场，可以在机上进行更换。 因为 LRU 的直译就是 “航线可更换单元”； 在航线上，可以便捷地进行拆换。 只有这样才能保证维修效率，因此 LRU 的设计应该按照统一的标准，以兼容标准工具。 （维护人员可以按照飞机维修手册 AMM，开展工作）； 机上拆下后，可 …

2023年9月11日 · Line-replaceable units (LRUs) play a vital role in the aviation industry by simplifying maintenance procedures and ensuring the efficient operation of critical aircraft systems. These easily replaceable modules allow technicians to quickly identify and replace faulty units, minimizing aircraft downtime and enhancing overall safety.

2023年7月4日 · Line-replaceable units (LRUs) are commonly used in airplanes. Also known as line-replaceable items and line-replaceable components, they consist of aircraft components that can be removed and replaced on the fly. Airplanes …

2016年6月12日 · An LRU is an essential support item which is removed and replaced at the field level to restore the end item to an operational ready condition. Conversely, a non-LRU is a …

2020年3月20日 · 航线可更换单元（Line Replaceable Unit，LRU），指飞机在航线维修期间，可以方便地使用标准工具在飞机上（原位）直接更换的具备独立功能（如控制、作动、保护、过滤等）的部件、组件等。

2018年6月10日 · A Line Replaceable Unit is a piece of hardware that can be exchanged for a replacement part in a relatively short time by only opening and closing fasteners and …

2023年8月8日 · In simple terms, an LRU is a unit that can be easily removed and replaced by maintenance personnel when needed, without causing significant disruption to the aircraft’s operations. Let’s delve deeper into the concept of LRUs and understand their significance in the context of the Boeing 737.

2024年11月11日 · LRU（Least Recently Used）算法的核心思想是，当缓存空间不足时淘汰最近最少使用的缓存项。 它通过记录每个缓存项的使用时间来实现这一点。 常见的实现方式有以下几种： 链表实现：使用双向链表将缓存项按访问顺序串联起来，每次访问移动到链表头部，淘汰时移除尾部节点。 哈希表+双向链表：使用哈希表快速定位缓存项，链表维护访问顺序，常见于一些标准库的实现（如Java的LinkedHashMap）。 这种基本的LRU实现虽然简单，但在某些场景下 …

Maintainability assessment is an important requirement while designing an aircraft engine because it determines whether Line Replaceable Units (LRUs) can be accessed for replacement or periodic inspection or on-wing adjustments. In the …
