Fuel system breakaway valve reaction bridge and reaction collar

An aircraft comprising:

• an airframe;
• an engine disposed at the airframe;
• a flexible fuel bladder disposed at the airframe and in flow communication with the engine, having an opening to allow a flow of fuel into and/or out of the flexible fuel bladder;
• and
• a fuel line disposed at the opening;
• a breakaway valve operably connecting the fuel bladder to the fuel line at the opening to control a flow of fuel therethrough;
• and
• a non-contacting or loose fitting reaction feature affixed to the airframe and interactive with the breakaway valve such that movement of the breakaway valve relative to the reaction feature results in breakage of a valve body of the breakaway valve and closure of the breakaway valve to prevent flow of fuel therethrough as well as to also allow the fuel line to act directly on the breakaway valve if it should be pulled upon, wherein the reaction feature of the airframe interacts with a reaction flange of the breakaway valve to break the valve body.
