''Making stuff… Simpler''
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)!”
The Antikythera mechanism is more valuable than Mona Lisa!
says professor Michael Edmunds from Cardiff University, who led a 2006 study of the mechanism!
Honestly, this is one of the most mysterious, extraordinary, fascinating & interesting machines I’ve ever seen in my life! The Antikythera mechanism is one of the most remarkable inventions of the ancient world that came to light in 1900 when a Greek Sponge diver discovered the wreck of an ancient Greek or Roman cargo ship that had sunk off the Greek island of Antikythera around 80 B.C.E!

I mean seriously what do these engineers & scientists at NASA are made of ? I know they’re made of atoms but still.. I mean how do they come up with such awesome cool stuff every time !
This time, it’s something you would not have even thought of. Yea… we are talking about NASA’s Starshade mission! (watch the video below) more “NASA’s Starshade to help find another Earth !”
Designing a car & making it is not as easy as sitting & watching a movie on a couch. Making a car doesn’t just mean to join the parts we bought; it needs to have deep knowledge of thermodynamics, fluid mechanics, dynamics & must also be able to do calculations which fits the rules & which doesn’t damage the car. One cannot do this being a book worm; it requires lot of creativity, ‘engineering expertise and motor racing skills. Team Ashwa has proved that they have all these qualities.
R S Kulkarni who advises the team says:
The team is the number one formula racing university team in the country. It competes with teams from US and Europe who have vast financial and other resources at their disposal.
We have to work with what we can afford. They are also competing against teams which have more than two decades experience in automotive racing. Yet the team has bagged the best Asian team award and is in the top rankings
The body of the car is made from glass fibre. Also the engine is taken from an crashed bike to reduce the expenses.
They say that the engine capacity is 600 cc & can hit a top speed of 100 km/hr or a few more.
It cost them around 15 lakh Rs to make it. Total 7 prototypes were made; the last one made in 2011.
Kulkarni says that this amount may seem high at first, but when compared to foreign teams who spend around whooping Rs 2 crore to design and build their own cars. “One thing we have been appreciated for is the cost-effectiveness of our car and yet its very good performance.”
The car model name was earlier RVIANZ, to commemorate student life at RVCE. Later, it was shortened to RZ.
Ashwa team has been participating in the competitions of FSAE since 2005. This is because they completed their first prototype(out of 7, as I mentioned earlier) in 2005. They participated in the competition in 2005 & 2006 in Australia followed by 2007 & 2008 in Germany & 2009-10 in Italy.
The team’s last prototype, RZ X, successfully completed the Formula ATA Italy event in 2010 winning The Best Asian Team award.
If anyone is wondering – why the word Ashwa ? what does it mean ? Well, I should tell you that Sanskrit is most ancient & philosophical language of India. According to Sanskrit, Ashwa means Stallion. Hence, the name was chosen for the team.

No more boring introductions, lets get started & understand how does a Wankel engine work & what exactly it is !
History :-
The first Wankel engine was developed by German engineer – Felix Wankel. Wankel received his first patent for the engine in 1929. more “How does a Wankel engine work ?”
We Humans, being a couple of feet high, weighing barely a quintal are capable of making & building things million times bigger & heavier than us & we have proved it. Hats off to those engineers who have built them !
So lets have a look at the top 10 biggest machines of all time which we’ve never imagined of !
These are the machines which are so big that you might have to walk a kilometre or so to view them completely.
So get ready to get your jaw drop…!
