vehicle has been a one of the major challenging problem for many year. By comparing the fuselage of a conventional aircraft which is a cylinder shape‚ the stress level of a flatter shoebox shape type BWB fuselage has a higher magnitude ‚because the internal pressure causes blending stress of the whole fuselage instead of the stress act on the skin membrane. Due to the primary design of the conventional fuselage structure are focus on membrane stress‚ a new design and material are needed ‚in order

For better lift‚ the wing structure should be better. 6.3.2 Structural Design The large Wingspan means aero elasticity influences on aerodynamics and especially on dynamic stability and control. In order to minimize such interferences and movements in the solar array‚ the wing should have

Aircraft fuselages are built in the form of shells that must withstand the compression and forces applied to them without buckling (SAGES Module 2). An inherent problem with using large‚ thin sheets of aluminum alloy in the construction of the fuselage is its weakness to collapsing under high compression in areas without support. This weakness is overcome by using longerons

Fuselage The fuselage (/ˈfjuːzəlɑːʒ/; from the French fuselé "spindle-shaped") is an aircraft’s main body section that holds crew and passengers or cargo. In single-engine aircraft it will usually contain an engine‚ although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage which in turn is used as a floating hull. The fuselage also serves to position control and stabilization surfaces in specific relationships to lifting surfaces‚ required for aircraft

The overall characteristics are largely determined by the original design objectives. Most airplane structures include a fuselage‚ wings‚ an empennage‚ landing gear‚ and a power plant

Reducing the earth scooping effects encountered in longitudinal impacts should include a large‚ relatively flat surface thereby increasing the aircraft’s tendency to slide over the impact terrain and by minimizing inward buckling of the fuselage nose or engine nacelle to maintain skid surface integrity. 2.

Our world today is characterized by efficiency from minor things to making coffee in the morning to determining the most effective and aerodynamic structure for a common day fuselage. Now imagine our world‚ one that strives for efficiency‚ without Internet. I wouldn’t guarantee that efficiency would overcome simplicity in a world where communication is scarce and a source of information is uncommon. The dilemma at our hand is that people do not acknowledge the fact that even though the Internet might
