What is the primary function of baffles in fuel tanks?

The primary function of baffles in fuel tanks is to minimize fuel movement during flight. Baffles are structures within the fuel tank that help to dampen the motion of the fuel as the aircraft maneuvers. This is crucial because if the fuel sloshes around excessively, it can affect the aircraft's stability and control, particularly during critical phases such as takeoff and landing. By reducing this movement, baffles help ensure a more consistent center of gravity and prevent the potential for fuel starvation in the fuel lines due to sudden shifts in the fuel's position.

While increasing fuel capacity, heating the fuel, or allowing for faster refueling may seem relevant to fuel systems, these functions do not align with the primary purpose of baffles. Baffles are specifically designed to enhance safety and performance by stabilizing the fuel within the tank throughout various flight conditions.
