Abstract
In the field of agriculture and aerial firefighting, some example vent systems for aircraft fluid dispersion tanks include a vent-well recessed below the top of the tank. When a gate valve assembly below the tank opens to release fluid for dispersion along the aircraft's trailing flight path, the vent system prevents a detrimental vacuum from developing within the tank. In some examples, a recessed vent exploits the Coanda effect to direct air into the tank without obstructing the pilot's view. In some examples, a low profile scoop above the vent further promotes airflow with minimal visual obstruction. In addition or alternatively, some example vent systems include a lightweight cable connecting the gate valve assembly to a spring-loaded vent. The cable pulls the vent open in response to the gate opening to release fluid. When the gate closes, the cable becomes slack, which allows the spring to close the vent.
