When on the ground, the spar supports the weight of the wings and flying loads. The spar or spars may be linked to other structural and forming parts like ribs, and stressed skin construction may be employed in some applications to share loads.
A wing could have several spars or none at all.Wing Spars can be compared to the framework or skeleton of an aeroplane wing. To maintain its position, the Fuselage is secured to the Wing Spars.
Inspections of the airframe and fuselage may also include a look at the spars to assess the wing’s structural condition. In order to prevent buckling under applied stresses, “L” or “T”-shaped spar caps are often welded or riveted to the top and bottom of a standard metal spar in a general aviation aircraft.
A container used to hold compressed hydrogen is known as a hydrogen tank. Gaseous and liquid forms of hydrogen can both be stored. While using a gaseous storage tank, compressed hydrogen is kept under pressure.
A cryogenic storage tank, on the other hand, operates by keeping hydrogen in liquid form. There are four common types of cylinders used to store hydrogen: Type I cylinders are all-metal, Type II cylinders are all-metal hoop-wrapped composite, Type III cylinders are fully wrapped composite with metallic liners (such as Al-6061), and Type IV cylinders are fully wrapped composite with nonload bearing nonmetallic.
GLOBAL AIRCRAFT WING SPAR HYDROGEN TANKS MARKET SIZE AND FORECAST
The Global aircraft wing spar hydrogen tanks market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.

In the wing spar tanks of an Apus aircraft, hydrogen is stored. Apus Group’s hydrogen-powered twin-motor i-2 aircraft was mocked up at Aero Friedrichshafen to show off the installation of the fuel cell and power controller in the forward fuselage. This aircraft has zero emissions.
The tubular wing spars used as tanks by the i-2’s designer’s “structurally integrated hydrogen storage system” is effective. The initial two thirds of each wing’s span are roughly covered by the four spars that each wing has. The pressurised hydrogen load is only around 30% of the load placed on the rounded carbon fibre spars, which can withstand pressure up to 300 bars.
A spar weights between 80 and 85 kg. The eight spar tanks have a combined capacity of 23 kg of hydrogen. The i-2’s two 135 kW electric motors work in tandem to burn five kilogrammes per hour, providing the aircraft a 500 nm range and a 160 knot cruise speed. Each propulsion system consists of a motor, power controller, and PowerCell fuel cell that operate as identical power channels.
