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.
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.
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.
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 company developed its own aircraft design software, Advanced Aircraft Analysis (AAA), as well as a second design program for a NASA Small Business Innovative Research contract. [5] In 2002 he published Roskam's Airplane War Stories a collection of stories about airplane design and analysis and engineering mistakes that were made. Many of ...
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]
An aerostructure is a component of an aircraft's airframe. This may include all or part of the fuselage, wings, or flight control surfaces.Companies that specialize in constructing these components are referred to as "aerostructures manufacturers", though many larger aerospace firms with a more diversified product portfolio also build aerostructures.
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in tension.
