Abstract: An exemplary convertible engine includes an engine housing forming a fan duct extending from a fan inlet to an exhaust; a fan positioned in the fan duct proximate the fan inlet; an engine core located in the fan duct aft of the fan, the engine core coupled to the fan by a fan shaft; a drive shaft mechanically coupled to the engine core and extending exterior of the engine housing; and a dedicated core inflow duct coupled to the core and having a core inlet to capture and direct air into the engine core. An inlet barrier filter may be located in the dedicated core inflow duct. The core inlet may be located inside of the fan duct or exterior to the fan duct. A gearbox may be operationally connected to the fan shaft and may be located inside of the fan 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.
