ISO 18387-2019 航空航天--线性液压执行机构--一般规范 Aerospace — Linear hydraulic utility actuator — General specifications

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.st edition 2019-09 Aerospace — Linear hydraulic utility actuator — General specifications Série aérospatiale — Actionneur hydraulique linéaire à usage général — Spécifications générales Reference number ISO 18387:2019(E) ？ ISO 2019 ISO 18387:2019(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2019 All rights reserved.
