Main Spar. The purpose of these machine screws is to help spread the load from the aluminum web inserts into the E glass web itself. The exact location of the screws are not critical, and they do not need to align with the 1/4" bolts on the fwd spar web even though figure 2-4 shows them as being in relative alignment.

The two spars consist of primary and secondary spars. For this study, NACA 23015 is chosen as the baseline airfoil as this airfoil is very similar to the customized airfoil being used in...

Jun 21, 2021 · Airbus A320 aircraft wing was chosen for the purpose of structural design and analysis. Spars were designed based on maximum bending moment and shear force that the wing can resist. 3D geometric...

To achieve this, the wing spar has a stump at the inboard edge that is inserted into a hole in the either the fuselage or the next inner wing section. Once inserted, they are locked to the fuselage (and often to the wing on the other side) using large metal pins.

Main spar of a de Havilland DH.60 Moth. In a fixed-wing aircraft, the spar is often the main structural member of the wing, running spanwise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of …

Wing panels and spars can now be automatically tacked together under continuous clamp up in their assembly jigs using EMR. This eliminates the requirement for disassembly, debur and cleaning required with the manual process.

Aug 6, 2017 · The spar web consists of the material between the spar caps and maintains a fixed spacing between the them. This allows the spar caps to act in pure tension and compression (bending) during flight. The spar web is responsible for carrying the vertical shear loads (lift) which arises from the aerodynamic loading of the wing.

Jul 1, 2020 · Each A320 spoiler has different dimensions depending on its location on the wing but, generally speaking, measures 1.8 meters long and 0.7 meter wide. Each spoiler is about 50 millimeters thick at the leading end and tapers to about 5 millimeters at the trailing edge.

Airbus’s “Wing of Tomorrow” R&D project is mainly aimed at developing new technologies for the “new A320” wing. GKN Aerospace is responsible for the research and development of the aircraft’s trailing edge spar. The “new A320” wing box is 17 meters long.

The DGAC received reports of localised debonding of spar, stringer, and rib to skin attachments on several Vertical Stabiliser Spar Boxes. The debonding resulted from bonding surface contamination during production process. Such debonding could affect the structural integrity of the Vertical Stabiliser Spar Box.
