The 787 is the only jet-powered passenger aircraft I'm aware of that doesn't use a bleed air system. Any pressurized-cabin turboprop aircraft uses bleed air, and so does the M1 Abrams tank. Bleed air is not just used for cabin pressurization, it's also used for anti-icing systems, cabin temperature control (the high-pressure air is the working fluid, see https://en.wikipedia.org/wiki/Air_cycle_machine), and nitrogen generation systems for fuel tank inerting. (I worked on the environmental control system for the Gulfstream G650 many years ago) |
