A Study of Composite Empennage Spar Product Key Characteristic Identification Method
A composite empennage spar product key characteristic identification method is proposed in this pa-per.To obtain the functional requirements of composite spar,a functional analysis is conducted by considering em-pennage main box as a system and the composite spar as its subsystem.By performing a Design Failure Mode and Effect Analysis,the key characteristics of composite empennage spar are obtained through the rank of Risk Priority Number.The cost to improve the product quality can be as lower as possible through the identification and control of the product key characteristics.
