Title:
BUBBLE COLLECTOR FOR SUCTION FUEL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/099860
Kind Code:
A3
Abstract:
A fuel feed system for a rotary-winged aircraft includes a fuel feed line extending from a fuel source to an engine and an engine fuel suction pump disposed at the fuel feed line to urge a flow of fuel through the fuel feed line to the engine. A collector is located along the fuel feed line between the fuel source and the engine to collect air-vapor bubbles which form in the flow of fuel. An air-vapor line extends from the top of the collector and merges with the fuel line section between the collector and the engine fuel pump. The air-vapor line is sized and configured to limit the flow of air-vapor from the collector to the engine fuel suction pump to a rate which the engine fuel suction pump can tolerate.
