航空航天.线性液压执行机构.一般规范

[中文适用范围]： 本文件规定了线性液压实用致动器（本文称为“实用致动器”）的一般要求，用于压力高达 35000 kPa（5000 psi）的飞行器液压系统。 这些要求包括： ——设计要求； ——测试要求。 本文档旨在与每个应用程序特有的详细规范结合使用。 注：虽然制动活塞和起落架转向架（卡车）变桨距调节器是实用执行器，但它们超出了本文件的范围。 这是因为这些设备被认为是专业执行器设备，因为它们的特定工作周期需要一套单独的定制要求。 [外文原描述]： This document establishes the general requirements for a linear hydraulic utility actuator, herein referred to as a "utility actuator", for use in flight vehicle hydraulic systems at pressures up to 35 000 kPa (5 000 psi). These requirements include: — design requirements; — test requirements. This document is intended to be used in conjunction with the detail specification that is particular to each application. NOTE Although Brake pistons and Landing Gear Bogie (Truck) Pitch Trimmers are utility actuators, they are outside the scope of this document. This is because these devices are considered to be specialist actuator devices due to their specific duty cycles requiring a separate set of tailored requirements.
