The first airplane created was by the Wright Brothers in 1903. Can you imagine that? More than 100 years ago, these 2 guys figured out how to fly a heavy and large object!
Then in 1939, the first-ever jet was created, an airplane that flies with turbines rather than a propeller. By 1986, Boeing had created the 707, which became the first mass-produced commercial jet airliner.
Today, airplanes are used for everything, from travel, transportation of cargo, military, and even recreation. As there are hundreds of thousands of them all over the planet, you’ll see them stored in wonderfully huge garages called ‘hangars’. These oversized garages have huge doors, nice smooth polished concrete floors, and can span over multiple acres worth of land.
And these planes are so advanced, that most mainstream jets can actually fly themselves! Of course, the large commercial jets will likely always have a pilot though, just in case…
How an airplane propellor works
A propellor has to be just right for an airplane to work. Too small, it won’t generate enough thrust. Too big, it won’t generate enough speed. So there are exact calculations that show how big a propellor should be to get the size of the plane up. Everything else about it has to be just right as well. The speed of it rotating, the angle each blade is at, etc.a
As the propellor rotates from a basic rotary engine, it creates what’s called a ‘slipstream’. This slipstream of force travels slightly angled upwards towards the wings, and then at the right speed, you have a flight!
How jet engines work:
Jet engines typically refer to jet propulsion. It works simply by, igniting the fuel, then with a huge turbine, it pushes the hot air backward into a narrow hole, causing propulsion. It’s the same as if you’re spraying a hose and you narrow the nozzle at the end and it creates a much faster and higher pressure stream.
Here are some pics of some common propellor planes and jets used today:
