Very few are lucky enough to take a ride in a Chopper & I am happy to be one of them ! Anyway, helicopters are indeed one of the most interesting machines from which I know so far. Subjects like flight mechanics & helicopter dynamics are not for weak hearted ones; they are seriously challenging to study ! Well keeping those complex calculations, equations & relations aside, lets at least know how helicopters work, fly & are steered ! more “How helicopters work, fly & turn (Animation) ?”
Rotary Gnome engines were widely used in aviation before & during WW I ! Besides aviation, Gnome engines were also used in some early motorcycles & aircrafts. So lets see what are & how do rotary engines(gnome engines) work ? more “How do Rotary engines(Gnome engines) work ?”
Radial engines were widely used during World War II.
More efficiency & power were the greatest needs of that time. Having many advantages over the rotary engines used in World War I, radial engines proved to be great for aircrafts.
The first jet engine successfully flew in August, 1939.
Hans von Ohain of Germany was the designer of the first operational jet engine, though credit for the invention of the jet engine went to Great Britain’s Frank Whittle. Whittle, who registered a patent for the turbojet engine in 1930, received that recognition but did not perform a flight test until 1941.
Its been more than 75 years, there has been continuous development in jet engines & has a significant increase in their efficiency. There are many types of jet engines depending on their construction & power they can deliver. Todays jet engines are able to produce so much of thrust that airplanes could fly at speeds multiple times the speed of sound ! more “Types of Jet Engines (animations)!”
Rotary/gnome engines were used to power aircrafts during WW-I & radial engines during WW-II. Then came the era of jet engines which completely revolutionized the aviation technology ! Jet engines were very much efficient & powerful than those used during World wars ! The power jet engines deliver is so high that an airplane weighing hundreds of tons lifts off the ground with such ease. How are they capable of producing so much of power/thrust ?
So lets not waste our time & have a look on how do jet engines work ? more “How do Gas turbines or Jet engines work ?”
Earlier in the Engines section we saw how 4 stroke & 2 stroke engines work ! We might like to give a thought on which is better one OR which has more advantages. So in this article we are going to discuss about the differences, advantages & disadvantages of 4 stroke & 2 stroke engine. more “Differences, Advantages & Disadvantages of 4 stroke vs 2 stroke engine”
Human started with just wheels for travelling & transportation purposes at first. Then came bikes, cars & trains which could be driven on land. The next difficulty was to overcome the vast oceans & seas which led to invention of ships. Engineers are still finding ways to make today’s vehicles more better & efficient even though we have achieved success in almost every mode of travelling & transportation. One of the extraordinary machine in history of vehicles is hovercraft. Lets see how does a hovercraft work ? more “How does a hovercraft work ? | Design & Application”
