Question

How are jet aircrafts that fly at high altitudes pressurized?

Answer 1

Bleed air from the Compressor Stage of the engine is fed into a Pneumatic system complete with Heat control via the "Packs" the air from there is then fed into the Cabin where it keeps going, Constant air flowing through this system keeps the cabin air Clean with the freshest air from outside and also pressurized, as a matter of fact if it wasn't for the Valve that releases pressure to maintain the Max Delta Pressure for the cabin, the cabin would actually over pressurize :), most boeings are certified for about 8PSI of cabin pressure that makes your ride at 30,000 feet feel like about 4000-8000 feet.

Answer 2

A plane flies at about 30,000 feet. The air pressure at 30,000 feet is significantly lower than at sea level (4.3 psi versus 14.7 psi). High-pressure air is used to "pump up" the cabin in much the same way that a tire is pumped up. The high-pressure air on most planes comes from the compression stage of the jet engines

Answer 3

Use bleed air from the engine and fill the cabin, but its really controlled by how much of that air is being released from the plane through the outflow valve.

Answer 4

inside the jet engine air gets pressurized and that goes in the fuselage.

Answer 5

its basicly how they do compressed air

the pump that air into the cabin and compress it so that its mor pressurized than the outside

Answer 6

it is just air that flows through the cabin

Answer 7

It takes pressurized air from the jet engine and route it to the cabin.

Good Luck...
