Research on Civil Aircraft Ram Air Turbine System Airworthiness Engineering Technology

Abstract

Ram air turbine(RAT)system is a kind of aircraft emergency energy,which is critical of aircraft to provide emergency hydraulic source and/or emergency power supply for aircraft in emergency.Referring to AP-21-AA-2011-03-R4 about aircraft life cycle certification process division and certification activities,combined with the development process of a certain type of civil aircraft RAT system,this paper starts from identifying the certification basis,transforms the airworthiness clauses into requirements,which are implemented into product design,clarifies the compliance methods and verification ideas of the clauses,and finally determines the workflow and method of civil aircraft RAT system airworthiness engineering technology.The workflow has been preliminarily verified by the development of a civil aircraft RAT system,which provides a reference for the development and certification process of domestic civil aircraft airborne system.
