At 35,000 feet, a human would suffer severe oxygen starvation without a pressurized cabin. Also known as "death". A pressurized cabin in a commercial - or military - airliner is essential at high altitude.
If the aircraft is coming into land then the hinged part of the wing called Flaps are lowered to increase the amount of Drag over the wings. If you think of drag as an air-born form of braking then Flaps down means the aircraft the aircraft slows but increases the maneuverability the pilot has over the aircraft. If the aircraft is on the ground then wheel brakes are very useful
As the aircraft travels at high speeds through the air, friction between the air and the body of the aircraft create charge. This is why aircraft's have special rubber wheels which contain a conducting material, to release the charge into the ground when they land.
Aircraft wings can move up and down as part of the normal operation of the aircraft. This movement helps to control the flight of the aircraft by adjusting the lift and drag forces acting on the wings. The wings can also move as part of the aircraft's flaps and slats system to change the wing's shape for takeoff and landing.
An aircraft that achieves forward propulsion by expelling a stream of fluid is called a jet aircraft. Jet engines, such as turbojets or turbofans, expel high-speed exhaust gases to generate thrust and propel the aircraft forward.
Hollow bones
Basically, an aircraft flies, a hovercraft doesn't. An aircraft relies on aerodynamic lift, a hovercraft is "lifted" by a cushion of pressurised air trapped in the plenum chamber.
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.
In a pressurised nuclear reactor the temperature is very high, which cn be accepted as a point for this.
As aeroplanes fly high in the atmosphere, where the air is thin, the inside has to be pressurised to allow the passengers and crew to breath.
no
They take it with them, in pressurised tanks.
because it has been pressurised in a similar way (outcome) to how a commercial airplane is pressurised for passengers to fly at altitude.
yes
Generally, yes
no your gonna die
The air in an aircraft needs to be pressurised so that the people within the cabin don't pass-out from oxygen starvation at higher altitudes. The atmosphere can be described as a load of blankets wrapped around the world, the bottom layer has all the weight from above and is squashed, but as you go further up, there is less pressure on the blankets. this is the same with air... at sea level there is plenty of oxygen in the atmosphere to breathe, the higher you go the more sparse the air becomes and less oxygen is available for breathing. Aircraft are usually pressurised to the equivalent of 8,000ft as this is a safe threshold for breathable air.
Keg beer is a term for beer which is served from a pressurised keg. Watney's (UK) started with an experimental pressurised beer Red Barrel which was served in a pressurised Keg rather than the traditional Cask (barrel) in 1936. The use expanded rapidly circa 1960
