Aircraft Fuselage Structural Design Vrogue Co

Aircraft Fuselage Structural Design Vrogue Co The fuselage is the name given to the main body of the aircraft and houses the pilots, crew, passengers, and cargo. the wings and tail section are attached to the fuselage, and depending on the design of the aircraft, may include engine attachments too. figure 1: boeing 737 carries passengers and cargo in the fuselage. This is part 7 of a series on the fundamentals of aircraft design. in part 6 we looked at the structural make up of the wing. in this post, we move away from the wing and introduce aircraft fuselage design: we’ll look at the various ways to construct a fuselage, how to size it correctly, and introduce the various loads that the fuselage structure is expected to carry during operation.

Aircraft Fuselage Structural Design Vrogue Co The fuselage should carry the payload, and is the main body to which all parts are connected. it must be able to resist bending moments (caused by weight and lift from the tail), torsional loads (caused by fin and rudder), and cabin pressurization. the structural strength and stiffness of the fuselage must be high enough to withstand these loads. The ultimate wing design load is applied as a normal upward pressure step load at 10 wing stations. the maximum tip deflection at this ultimate 2.5g design load is 56.9 inches. the fuselage has 80 frames at 20 inch spacing, nose cone, tail cone, and two bulkheads. total fuselege nose to tail length is 1862 inches. The aim of this mini series is to provide an introduction to aircraft structures and the control surfaces attached to the wing and tail. part one is an overview and focuses on loads generation, structural design philosophies, and the material used in airframe manufacture. part two looks at the fuselage in more detail. Aircraft level optimisation of fuselage structures considers global level analyses of the fuselage structure while focussing on the sizing of local structural design variables that represent the thin wall properties of the structure, like skin thicknesses and stringer dimensions [2].
