摘要： In some aspects, a master cylinder assembly for vertical lift aircraft is configured to move pressurized fluid through a conduit in response to applied movement of an input lever. A low pressure relief valve can be connected to a first conduit to limit pressure to a low level. An isolation valve can be connected to the first conduit and configured to isolate the low pressure relief valve from the conduit when engaged. A high pressure relief valve can be connected to a second fluid conduit to limit pressure to a high level. In some aspects, a rotor brake actuator is fluidly connected to the first conduit and the second conduit and configured to engage a rotor brake in response to hydraulic fluid pressure.

摘要： A fluid connection system for fluidly connecting a pair of fluid reservoirs, such as fuel cells, includes a bellowed portion surrounding a connection portion through which fluid can flow between the two reservoirs. The bellowed portion allows for relative movement between the two reservoirs without breaking the fluid-tight connection between the two reservoirs. Also, a guard member surrounds at least some of the outer periphery of the bellowed portion. The guard member serves as a shield around the fluid-tight connection and bellowed portion, and thereby helps prevent damage to the fluid-tight connection in the event of a crash or hard landing.
