Aircraft Spar - In a fixed-wing aircraft, the wing is the main structural member of the wing, running at right angles to the span (or around it depending on the wing) to the fuselage. Scattered flight carries the load and weight of the wings on the ground. Other structural and forming members, such as spar or spar ribs, also share the applied load due to the tension of the construction skin. Multiple fins scattered or absent. Where one spar is of great value, it is known as a spar-chum.
Spars are used on other surfaces of aerofoil aircraft such as tailplanes and fins and have a similar function, although the loads transmitted by these spars are different.
Aircraft Spar
The spar fin provides greater weight support and the dynamic load integrity of the cantilever monoplane, often combined with the wing's "D" box support. Together, these two structural elements together provide the wing's stiffness so that the aircraft can fly safely. struts to make cross-sections smaller and therefore use lighter spurs at the expense of increased drag.
Bottom Wing Work
Many of these loads have suddenly slipped into flight, such as the Xtra 300, which perform highly aerobatic maneuvers; Many of these aircraft are designed to safely support large payloads.
At first, builders often used fireplaces carved from solid pitch or ash. Many types of wood sprinklers have been used and tried as sprinklers, which are in the form of a box; And the scattered laminates are clamped in a jig and compression to retain the dihedral wings. Scattered wood is still used in light aircraft such as the Robin DR400 and its relatives. The disadvantage of spar- wood is the damaging effect of dry and wet environments and biological risks, such as the infestation of wood boring insects and fungal attacks can cause parts; Hence, regular inspection should be done to maintain the quality of the air.
A wood spread wing consists of several constructions usually consisting of top and bottom members, called spar-caps, and members of a vertical sheet of wood called shear webs or more simply webs, which are closed with spar-gals.
In more recent times, "replica aircraft builds" like Spitfires use scattered wood-laminated replicas. These beams are usually made of spruce or Douglas fir (slatted and glued). Many enthusiasts build "replica" Spitfires that can actually fly using different guns to the size of the aircraft.

Typical metal spars in the aviation industry typically consist of aluminum spar sheets, with "L" or "T" spar caps attached to the top and bottom of the sheet to prevent tearing under applied loads. Larger aircraft using this spar-structure method may have sealed wings to provide integral fuel tanks. As in Ocean Crete Airlines Flight 101, tire-sparing metal wings are an obvious causative factor in airplane crashes, especially in older airplanes.
The 1917 German Junkers J.I fuselage of the armed attack sasquatchplane used Hugo Junkers' network of multiple tubular spar wings, simply placed under a duralumin wing sheet cover, with each tubular spar attached to the space frame. Duralumin triangular strips - typically truss-like in a battle layout - were attached scattered, resulting in a significant increase in structural strength when most other aircraft designs were built almost entirely with wooden wings. Junkers corrugated metal-clad alls/multiple tubular spar-wings were developed after World War I by American airplane designer William Stout for the 1920s Ford series of three-engine airliners, and by Russian aerospace designer Andrei Tupolev for aircraft such as his 1922 Tupolev ANT-2, The Great Magnificent He surpasses Maxim Gorky in 1934.
A design aspect of the Supermarine Spitfire's wing, which contributed greatly to its success, was the innovative spar-boom design, which was made of five square concentric tubes compacted into one. Two of these booms were joined together with a tin web, making it light and very strong.
A version of this sparse construction method was also used in the BD-5, which was designed and built by Jim Beda in the early 1970s. Spawned on the BD-5 and subsequent BD projects were primarily aluminum tubes about 2 inches (5.1 cm) in diameter, and joined at the root of the wings with larger-diameter aluminum tubes to provide structural integrity to the wing.

In aircraft such as the Vickers Wellington, spar-geodesic wing structures were used, which had the advantages of light weight and could withstand heavy battle damage with only a partial loss of strength.
Many modern aircraft use carbon fiber and Kevlar in their construction, ranging in size from large pods to small homemade airplanes. The famous compositions and developments of the glider come from the German glider manufacturers Schempp-Hirth and Schleicher.
These companies initially used solid fiberglass in their designs, but now they use carbon fiber in the skid steers, such as ASG 29. The increased strength and reduced weight in the propellers previously spared fiberglass allows for greater water ballast. to bear
An aircraft using three or more spars is considered a multi-spars aircraft. It allows the use of more spars, equivalent to the overall strength of the wing, but with more, shorter, spars, which results in a thinner wing or tail structure (increasing complexity and difficulty in the additional equipment package, such as fuel tanks, guns, ailerons, etc. ). Although multi-spar wings have been in use since at least the 1930s (for example, the World War II-era Curtiss P-40 had 3 spars per wing), they gained more popularity as the increasing speed of fighter jets required thinner wings. to reduce, to draw down They pull at high speed. The Mach 2 F-104-Starfighter used numerous thin airfoils to allow for the usual thin wing section; The F-16 Fighting Falcon uses a similar construction. The F-4 Phantom, F-15 Eagle, and other aircraft use 3 or more spars to provide sufficient strength in a relatively thin wing and thus qualify as a multi-spar aircraft.
The Path To Enlightenment
False spars, like main spars, are load-bearing structural members that run through the span but are not attached to the fuselage. The most common purpose is to carry moving surfaces, especially ailerons.

In terms of reducing the environmental footprint of tomorrow's aviation, distributed electric propulsion (DEP) has become an increasingly interesting concept. Due to the strong connection between the disciplines that promote this technology, many benefits are expected for the overall design of the aircraft. This fact is reflected not only in the aerodynamic properties of the aircraft, but also in the structural design. However, current statistical models used in conceptual design have shown limitations regarding the benefits and challenges that come from designing this new trend. Unlike the other methods, they are either not accepted for use in design time accounting or do not include CS-23-class aircraft. This paper describes a semi-analytical method compatible with performance-based certification criteria
