Abstract: A cooling apparatus includes a shared cooling device for one or more systems or components, and a plurality of primary cooling pathways. Each of the primary cooling pathways includes a transition duct and a fan. The transition duct is in fluid communication with the shared cooling device. The fan is in fluid communication with the transition duct.

Abstract: 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.
