Structural design methodology of electro-optical system installation on special mission jet transport aircraft

The research reported in this paper investigated the structural design methodology of equipping a jet aircraft modified for maritime patrol with any type of observation system. The study includes installation feasibility, definition of mounting types (fix/retractable), installation location, airworthiness requirements, design considerations, structural design requirements, and static/dynamic analysis considerations. Due to lack of design publication in this field, this study focuses on methodology of electro-optical sensor installation as a flowchart leading to a road map to equip an aircraft with any type of maritime sensor. For validation of above methodology, a case study for installation of an electro-optical system on a particular jet aircraft with new mission is presented. By comparison of system and aircraft specification based on methodology flowchart, a retractable mounting was chosen. To accomplish a safe installation, an optimal mechanism suitable with aircraft fuselage and required backup structure was designed using reinforced cut out. The design was then analyzed for static and dynamic critical load cases using MSC/NASTRAN software.
