Abstract
An apparatus includes a shared cooling device for cooling one or more systems or components, and a plurality of primary cooling pathways. Each of the primary cooling pathways includes a fan, and each fan is in fluid communication with the shared cooling device.
Claims17
A rotorcraft, comprising:
- a fuselage;
- one or more engines or a gearbox coupled to the fuselage;
- a shared cooling device coupled to the one or more engines or the gearbox;
- a shared connector in fluid communication with the shared cooling device;
- two or more of primary cooling pathways, wherein each of the primary cooling pathways comprises a fan in fluid communication with the shared connector via a transition duct, and wherein each fan is configured to draw air from the shared cooling device;
- and one or more secondary cooling pathways, wherein each of the one or more secondary cooling pathways comprises a distributed cooling device in fluid communication with the transition duct of one of the primary cooling pathways via a conduit, and wherein each distributed cooling device is operably coupled with one or more systems or components.
