What Does ETVA Stand For?

ETVA stands for External Tank Vent Arm

ETVA, or External Tank Vent Arm, refers to a specialized component used in aerospace engineering, particularly in rocket and spacecraft launch systems. Its primary function is to manage and control the release of vapors and gases from the external fuel tank during various stages of a launch. The ETVA ensures safe and efficient venting, preventing overpressure and maintaining operational integrity, while also supporting environmental compliance measures. This critical system enhances overall safety and performance in space missions.
