The US military uses diesel fuel in tanks as it's less flammable and explosive
The US military uses diesel fuel in its tanks, as diesel is less flammable and explosive than other fuel types. Diesel engines are also less likely to stall than gasoline-fueled engines, which is a crucial advantage in combat situations. The M1 Abrams tank, for example, can use a range of fuels, including ordinary gasoline, diesel, and jet fuel. However, diesel is the preferred option due to its safety characteristics.
The choice of diesel fuel is a strategic decision by the US military, as diesel engines offer a wide range of performance, efficiency, and safety benefits. Diesel fuel has a greater energy density than other liquid fuels, providing more useful energy per unit of volume. This is particularly advantageous for military vehicles, as it extends their operational range and reduces the frequency of refueling, which can be a vulnerable time for any vehicle.
The safety characteristics of diesel fuel are also a critical consideration for the military. Diesel is less likely to ignite and explode compared to other fuels, reducing the risk of accidental fires and explosions, both during combat and in training or transit. The lower flammability of diesel contributes to the overall safety of military personnel and equipment.
Additionally, diesel engines are known for their reliability and ability to handle demanding tasks. Diesel-powered machinery is commonly used in construction and farming, and the military benefits from this versatility as well. Diesel engines can provide the necessary power for tasks such as lifting steel beams, digging trenches, and moving heavy loads.
The use of diesel fuel in US military tanks is a well-considered decision, balancing performance, efficiency, and safety. By utilizing diesel, the military gains operational advantages and reduces risks associated with more flammable and explosive fuel types.

Aircraft use integral, rigid removable, and bladder fuel tanks
Aircraft typically use three types of fuel tanks: integral, rigid removable, and bladder. Each type has its own unique characteristics and advantages.
Integral fuel tanks are areas inside the aircraft structure that have been sealed to allow for fuel storage. They are often located in the wings, taking advantage of the otherwise unused space inside. These tanks are built into the aircraft structure, saving space and weight. Integral tanks are also the lightest type, offering the most space per unit of weight. They are common in smaller aircraft, with capacities ranging from a few hundred to several thousand litres, depending on the aircraft's size and design. However, they can be harder to repair if damaged.
Rigid removable fuel tanks, on the other hand, can be installed or removed as needed. They are typically made of metal, such as stainless steel or aluminium alloy, and are held in place with padded straps. These tanks are found in smaller general aviation aircraft, such as the Cessna 172. They are supported by the airframe but are not considered integral, as the aircraft's structural integrity does not rely on them. Rigid removable tanks can be taken out for maintenance or repair, making them convenient for addressing leaks or malfunctions.
Bladder fuel tanks, also known as fuel cells, are flexible containers made of reinforced rubberized or fuel-resistant materials. They are designed to fit inside the aircraft's cavities and can be rolled up and inserted into small spaces. Bladder tanks share many characteristics with rigid tanks but do not require as large an opening in the aircraft's skin for installation. They are easy to replace and less likely to leak. One downside to bladder tanks is the tendency for the materials to work harden through extensive use, making them brittle and prone to cracking.
The design and placement of these fuel tanks are carefully considered to balance fuel capacity with the aircraft's weight and performance. Engineers must ensure that the aircraft can fly extended distances without sacrificing safety and performance. Regular fuel tank checks and maintenance are crucial to prevent fuel contamination and leaks, ensuring optimal performance and safety during flights.

Bladder fuel tanks are reinforced rubber bags installed in aircraft
Bladder fuel tanks, also known as fuel cells, are reinforced rubber bags installed in a section of an aircraft's structure designed to accommodate the weight of the fuel. They are commonly used in many high-performance light aircraft, helicopters, and some smaller turboprops. Bladder tanks are rolled up and installed into the compartment through the fuel filler neck or access panel, and are secured using metal buttons or snaps inside the compartment.
Bladder fuel tanks are one of the three types of fuel tanks used in aircraft, the other two being integral and rigid removable tanks. Integral tanks are areas inside the aircraft structure that have been sealed to allow fuel storage, while rigid removable tanks are typically made of metal and can be removed for inspection, replacement, or repair.
Bladder tanks are flexible containers made of a laminated self-sealing material like vulcanized rubber, with as few seams as possible to minimize leak paths. When a fuel tank is punctured, the fuel seeps into the layers of rubber, causing the untreated layer to swell and seal the puncture. This technology was developed during the war to minimize the damage from leaking or burning fuel, as a conventional fuel tank, when hit by gunfire, could leak fuel and pose a significant fire hazard.
The use of bladder tanks offers several advantages, such as the ability to use as much of the aircraft as possible to store fuel, and their flexibility and quick transport and setup. However, one major downside is the tendency for the materials to work harden through extensive use, making them brittle and prone to cracking.
