Longerons, struts and stringers in a truss type fuselage structure [2]: 3–4 In an aircraft fuselage, stringers are attached to formers (also called frames) [3] and run in the longitudinal direction of the aircraft. They are primarily responsible for transferring the aerodynamic loads acting on the skin onto the frames and formers.
Structural optimization: Design of truss structures, beams, plates, and shells. Aeroelastic optimization: Design of aircraft wings and other components to reduce drag, weight, and ensure structural integrity. Material design: Topology optimization for designing materials with desired mechanical properties.
Some older types of aircraft design utilized open truss structure constructed of wood, steel, or aluminum tubing. [1]: 3–3 This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood.
Alloy 7075-T6 (70,000-psi yield strength), an Al-Zn-Mg-Cu alloy, was introduced in 1943. Since then, most aircraft structures have been specified in alloys of this type. The first aircraft designed in 7075-T6 was the Navy’s P2V patrol bomber. A higher-strength alloy in the same series, 7178-T6 (78,000-psi yield strength), was developed in ...
The weight of the aircraft is the common factor that links all aspects of aircraft design such as aerodynamics, structure, and propulsion, all together. An aircraft's weight is derived from various factors such as empty weight, payload, useful load, etc. The various weights are used to then calculate the center of mass of the entire aircraft. [37]
A box truss structure in a bridge of the Southern Pacific Railroad in California A box truss is a structure composed of three or more chords connected by transverse and/or diagonal structural elements.
Appearance/esthetics in aerospace design must at least co-exist, if not be synergistic, with the overall/societal fundamentals/metrics of aerospace engineering design. These metrics, for atmospheric flight consist of overall/societal factors directed toward productivity, safety, environmental issues such as noise/emissions and accessibly ...
English: Detail of a steel truss, like it is build nowadays, it uses welds and bolds due to the fact it is at site joint, where two parts get connected at site (see Plan of the tuss). It is a part of a Plan (File:Det JoKa008-Model.pdf), which shows three details of a truss (File:Fachwerkplan.pdf)
