Is the air in an aeroplane recycled throughout the journey?
Yes, it is re-cycled many times. This usually happens as 'bleed off' of engine intake air.
How an aeroplane without having any contact with land unlike a house on the land travelling in the air lands at the specified place when earth rotates speedily?
30 -35 minutes inside the tunnel. Quoting ROM Eurotunnel's website ... "What to expect during your journey "Passengers stay with their vehicle throughout the journey in bright, air-conditioned carriages. Sit back and relax, or get out and stretch your legs. The visual display screens offer information about your journey. Onboard staff will be happy to answer any questions. Whatever you choose to do, the 35 minute journey will be over much quicker than you think".
Whilst there were many endeavours to create an 'air plane' the first recognised successful designers of a heavier-than-air aeroplane were the Wright Brothers, who successfully kept their motorised air frame aloft for twelve seconds on December 17th, 1903. Brothers, Wilbur and Orville Wright first successfully flew glider planes in 1900 and began working on a motorised version of the aeroplane. This was at Kitty Hawk North Carolina.
It is air friction. An aeroplane flying into a headwind will use up much more fuel than an aeroplane flying with a tailwind. Air friction means that a feather would take much longer to reach the ground than a lead weight dropped from the same height. Yet, if the feather and the lead weight were to be dropped in a vacuum (not subjected to air resistance) they would both reach the ground at the same…
During the journey, the tyre heats up and heats the air inside the tyre. The air then slightly increases in pressure. After the journey, the tyre cools down and the air cools down too, restoring the original pressure. It is best to inflate tyres when they are warm so the pressure is correct when they are running.
On commercial airliners the jet turbines are also used to cram air into small ducts (at very high pressure) which is mixed with recycled air and then bled back into the cabin through the air conditioning.
