Composite Stress Engineers

TASKS
This project may form part of a high level objective to determine if satisfying the same requirements, using the same MoC as for metallic structure, will provide an ‘equivalent level of safety’ for composite structure.
For the purposes of this project (for defined and representative impact threats to representative composite structure critical to flight safety), the objectives and tasks are to establish, if:
Task 1: the inclusion of load is significant to composite impact behaviour
Note: This would be expected to involve test and analysis of unloaded and loaded composite structure subjected to impact,
Task 2: the behaviour differs significantly from that of metallic structure
Note 1: It is expected to involve test and analysis of unloaded and loaded metallic structure designed to meet the same design objectives as the comparative composite design in Task 1 of this study.
Note 2: This study is proposed with the bird strike threat in mind, when metallic structure has typically been impacted in test without load. However, this study does not necessarily need to be focused upon bird strike, although the threats and the structures must be representative of real threats and aircraft structures.
Task3: Analyse whether consideration should be given to related issues associated to F&DT, e.g. the relative visible delectability of damage resulting from impact with both loaded and unloaded structure should be established by using industry inspection standards
etc.
The outputs of the study work shall be fully documented including recommendations for amending certification requirements if deemed appropriate and acceptable means of compliance. Any recommendations should address practical steps to be taken. Also obstacles to implementation of the proposed recommendations shall be discussed in the final report.
