What are aircraft spars made of?
A typical metal spar in a general aviation aircraft usually consists of a sheet aluminium spar web, with L- or T-shaped spar caps being welded or riveted to the top and bottom of the sheet to prevent buckling under applied loads. Aluminum Alloys Aluminum is a common aerospace material selection for: Fuselages: Aluminum alloys are often used as the outer skin of fuselages. Wings: These materials provide structure to many components of aircraft and spacecraft wings, including the stringers and spars.Spars may be made of metal, wood, or composite materials depending upon the design standards of a specific plane.A long-range wide-body airliner and cargo aircraft. Main fuselage and wing spars are constructed of aluminium alloys.From a structural-weight standpoint, the 777 is primarily an aluminum airplane. Seventy percent of the overall structure is aluminum, including the wing box and fuselage. Of course, the aluminum alloys are not the garden-variety aerospace materials of the past.
What is an airplane spar?
Wing Spars can be thought of as the skeleton or the frame of an aviation wing. Fuselage is fastened to the Wing Spars to hold in place. Airframe and Fuselage inspections might also involve the inspection of the spars to determine the structural integrity of the wing. Spars may be made of metal, wood, or composite materials depending upon the design standards of a specific plane.Spars are typically made of wood, metal, or composite materials and are essential to a ship’s rigging system. There are several types of spars on a vessel, each serving different functions in relation to the sails and mast. Common types of spars include: Mast: The vertical spar that supports the sails and rigging.A spar is a pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include yards, booms, and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole.Spars may be made of metal, wood, or composite materials depending on the design criteria of a specific aircraft. Wooden spars are usually made from spruce. They can be generally classified into four different types by their cross-sectional configuration.The main spar is defined as a structural component in rotor blades that carries high lift loads, similar to the spar found in aircraft wing constructions, and is typically made from composite materials.

What does a spar look like?
Generally, most wing spars have a rectangular shape, with the longer dimension of the cross-section oriented vertically in the wing. In modern aircraft, wing spars are typically made from solid extruded aluminum or aluminum extrusions riveted together to form the spar structure. A spar is a structural member in an aircraft’s wing that is constructed perpendicular to the fuselage and spans the length of the wing. It is typically made of carbon fiber and is the most heavily loaded part of the aircraft structure, carrying both distributed and concentrated weight.A typical metal spar in a general aviation aircraft usually consists of a sheet aluminium spar web, with L- or T-shaped spar caps being welded or riveted to the top and bottom of the sheet to prevent buckling under applied loads.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 the wings while on the ground.Most wing structures have two spars, the front spar and the rear spar. The front spar is found near the leading edge while the rear spar is about two-thirds the distance to the trailing edge. Depending on the design of the flight loads, some of the all-metal wings have as many as five spars.
What type of spar is normally used in flight control surfaces?
Most spars are built up from extruded 7075 aluminium alloy sections, with riveted aluminium alloy web sections to provide extra strength. More recent aircraft have machined spars. Main fuselage and wing spars are constructed of aluminium alloys. Carbon composites used extensively in secondary structures. Engine exhaust cone made of titanium and engine pylons from titanium, steel and aluminium. Distinctive design with hump at front of aircraft.
