Why are submarines cabins pressurized?
To keep water from leaking in.
Why are airplane cabins pressurized?
Airplane cabins are pressurized because humans cannot breath at a very high elevation.Aircraft are pressurized to allow them to fly higher. Without pressurization, the amount of oxygen in the air would not be sufficient for humans to breathe.
What is the average flying altitude of a helicopter?
Most helicopters out there do not have pressurized cabins so the general service ceiling for helicopters today is 10,000 ft. So to answer your question anywhere from 0-10,000 ft. depending on airspace regulations.
What was the breakthrough technology introduced by Boeing 307 stratoliner in 1940?
Pressurized Cabins
How high can a helicopter go?
I believe the FAI world altitude record for a helicopter is 40820', and helicopters can now land on the top of Mount Everest, just over 29,000'. But practically speaking, helicopters rarely go over 10,000 feet as that's the altitude above which pressurized cabins and supplemental oxygen are required.
How are air craft cabins pressurized?
Pressure is created in the engines and/or APU as "bleed air" and enters the cabin.
Why must airplane cabins be pressurized?
Because at altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurised so that the internal pressure is equal to that at about 7,000 feet.
Why air crafts at high altitude must have pressurized cabins?
Mostly not enough oxygen in the air at the low pressure up there.
Why do passenger aircraft have pressurized cabins?
To allow passengers to breathe sufficient oxygen, needed to survive, even in high altitudes.
What are some technology's that you used in world war 2 still used today?
Pressurized cabins on today's airliners were used on B-29 Superfortress's.
Why are aeroplane cabins pressurized?
Airplanes often fly at great altitudes, of 10 kilometers or more. People would have serious trouble breathing at that altitude.
Why are aircraft cabins pressurized?
For two reasons: 1. To make the air breathable and comfortable. 2. In conjunction with the above, to keep the temperature at a safe level.
