Abwurfbehälter

Abwurfbehälter, often translated as "drop tank" or "external fuel tank," is a disposable fuel tank attached to an aircraft's exterior. These tanks are designed to carry additional fuel beyond the aircraft's internal capacity, thereby increasing its range and endurance. When empty, they can be jettisoned to reduce weight and improve maneuverability, or in some cases, they are designed to be recovered.

The primary purpose of abwurfbehälter is to extend the operational radius of military and civilian aircraft. For combat aircraft, this allows for longer patrol times, greater reach for strike missions, and the ability to carry more ordnance by freeing up internal space. In civilian aviation, particularly for long-range flights, they can supplement internal fuel when required, although this is less common than in military applications.

Abwurfbehälter are typically mounted on external hardpoints, often under the wings or fuselage. Their design varies greatly depending on the aircraft type and intended mission. Some are simple cylindrical tanks, while others are aerodynamically shaped to minimize drag. The materials used can range from aluminum to composite materials. The jettison mechanism is usually integrated into the aircraft's flight control system, allowing pilots to release the tanks under specific conditions. The use of abwurfbehälter is a common practice in aviation, significantly impacting operational capabilities.
