Pressurization is for the comfort of crew and passengers.
The planes fly higher to save on fuel. The less dense air higher up causes less drag. It is also unfortunately harder to breathe. Pressuriziation makes it easier to breathe without special equipment, like breathing apparatus or oxygen.
Supersonic jet planes
All aircraft, not just jets, have shapes as streamlined as possible to enable them to fly faster and use less fuel.
air pressure. low pressure above wing high pressure below caused by shape of wing if air was thinner (no oxygen in atmosphere) planes would need rockets on them instead of jet engines
No. If anything, it'll be the other way around. The pressurized bottle is a little heavier, and will float lower.
during the 1940's
To keep water from leaking in.
An airplanes cabin is pressurized with what is called "bleed air", air that is siphoned out of the compressor chamber of the engines. The air is directed through duct work to the belly of the plane, where it is filtered, cooled, then circulated in the cabin. Equal amounts of air are siphoned off each of the engines. If one engine should fail, the other engine(s) provide the bleed air.
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.
Pressurized Cabins
Jet planes fly with the help of Thrust and Lift produced by the jet engines.
Jet planes can be of many types and some perform better than piston planes.
Today's jet passenger airliners have pressurized cabins for it's passengers; this was pioneered in the B-29 Superfortess's that flew bombing missions over Japan during WW2.
Jet planes are faster than the normal propeller powered airplanes. Jet planes were invented by Sir. Frank Whittle. There are also supersonic Jet planes. Concorde was the fastest Passenger Jet plane.
There is not enough oxygen in the air at altitudes above about 17,000 feet. In addition, as you ascend, the temperature decreases. The temperature in which jet airliners fly often is minus 40 degrees or lower.
All collective nouns are common nouns.There is no collective nouns specifically for jet planes, however the collective nouns for planes can be used; they are:a fleet of planes (a fleet of jet planes)a squadron of planes (a squadron of jet planes)a stack of planes (a stack of jet planes)
Yes, jet planes are that - planes, whereas airlines usually refers to a company that uses planes to ferry people around.
Pressure is created in the engines and/or APU as "bleed air" and enters the cabin.
