2. The first aircraft had two wings made of light weight wood frames with cloth skins, held apart by wires and struts. US20060145010A1 US11/297,612 US29761205A US2006145010A1 US 20060145010 A1 US20060145010 A1 US 20060145010A1 US 29761205 A US29761205 A US 29761205A US 2006145010 A1 US2006145010 A1 US 2006145010A1 Authority US United States Prior art keywords wing spar cover airplane welding Prior art date 2004-12-07 Legal status (The legal status is an … An example is a wing whose tips can be moved up and down during flight. removed. Airplane wings, designed as airfoils, achieve this by interacting with the remote airflow to produce the desired lift. The spars and cross members may be made of other materials but I am under the impression they are mainly aluminum as well. 36-inch Rubber Pad Press The Aeroplane Factory's Rubber Pad Press has a 36" square lower platen and is capable of producing over 600 tons of pressure. Currently, most manufactured aircraft have wing spars made of solid extruded aluminum or aluminum extrusions riveted together to form the spar. With respect to airplane wings, these molecules exert a force on the airfoil, whenever they come in contact with it. Figure 8 shows examples of metal wing spar cross-sections. Using a Hot Wire Bow the wings are cut based on the template shape. The cooperation of Vought Aircraft and Boeing Commercial Airplane Company is gratefully acknowledged. Most modern planes are made mostly of aircraft aluminum. Air is composed of molecules moving randomly at high speeds. Generally high stress areas like wing/fuselage joints may be made of more rigid materials like steel. The increased use of composites and the combining of materials should make airmen vigilant for wings spars made from a variety of materials. A constant laminate thickness was used over wing span to simplified manufacturing process of wing segment prototype. The Irkut MC-21 is being manufactured by United Aircraft Corp. (Moscow, Russia) for the Russian market. ... A jet engine is mounted to the airplane wing with a pylon. Understanding Air at the Molecular Level. Airplane wings are made out of a specific type of aluminum, an alloy that offers a combination of lightness and strength comparable to steel that makes for easy flying. This means that on a high-wing airplane, the wing spar is … The parts of a jet engine—they can number 25,000—are made in various ways. 14). The pylon (and the wing) must be very strong, since an engine can weigh up to 10,000 pounds. The fan blade is made by shaping molten titanium in a hot press. Its wings are fabricated by AeroComposit (Moscow) using a Solvay Composite Materials single-component resin system. Or at least are skinned in aluminum. After the blanks are made, the wing templates can be aligned on them and the airfoil can be cut. While the idea of folding wings is not new – and was studied on the XB-70 Valkyrie aircraft back in the 1960s – it is usually achieved using a bulky arrangement of motors and hydraulic systems that can weigh down the aircraft. The process of removing and reattaching air and electrical cables – referred to as roots and vines – can take almost as long as the assembly process for each station. Inboard of the strut/wing junction, the upper member is loaded in compression in upright (positive G) flight and the lower member is loaded in compression. The work reported in the The wing spar and the strut system form a triangle in the front view. This press is capable of forming aircraft parts such as wing ribs as well as horizontal and vertical stabilizer ribs and caps or any other part that will fit within the lower platen dimensions. Wing root cross section of tested segment was extruded 750 mm in direction of removed outer spar. The hot wire follows along the template edge and cuts out the wing. The new wing part was used for clamping of the prototype during a static test of experimental wing (Fig. The upper wing and the struts 1 This chapter is based in part on [Cunningham, et al].
