More Information
Summary:A fuel system for a rotorcraft is provided. The fuel system comprises a housing, a fuel bladder located within the housing, a first fuel reservoir, and a number of pressure relief valves. The first fuel reservoir is in fluid communication with the fuel bladder and stowed within the housing. The number of pressure relief valves are configured to divert fuel from the fuel bladder into the first fuel reservoir at a predetermined pressure such that the first fuel reservoir expands to reduce forces on the housing during a crash event.
