Improvement in design of cockpit floor side member for supporting engine truss mount loads of a turboprop trainer aircraft

摘要

It is an aircraft structural design used for transferring Engine truss mount loads through Longerons(primary moment resisting member) to the fuselage structure of a turboprop trainer aircraft. The improved design has the minimum weight with no extra parts and eliminates the tooling time and cost required to form the extensive sheet metal build up structure. This improved design will effectively transfer the engine mount loads to the fuselage in addition to serving as a Cockpit floor side member. A single machined member made of high strength Al alloy is also used to establish web to web connection between top & bottom frames coming in the cockpit area and for providing continuity between skin and Covers. The design is constructed keeping in view the frequent inspection and maintainability associated with it.
