What does this balloon have to do with aircraft engines? Let's say that the physical principle behind what you are looking at, capable of generating the thrust of the balloon, is actually the same that allows the functioning of an infinite number of much more complex systems as we will see today, including a new aircraft engine that could be more efficient, quieter and more sustainable than any other engine installed on an airplane today. But let's not rush because we will cover all these topics shortly since recently there has been much talk of the development of an engine capable of drastically reducing CO2 emissions and bringing the aviation industry one step closer to the goal of zero-emission flights by 2050, would you believe all this? We know it seems like a dream, it's true, but thanks to the Rolls-Royce engineers and the Ultra Fan engine they are developing, perhaps it could become reality and today together here on the channel we will try to understand how engines of this type work, what the actual innovations are and above all why there is so much interest around this new Rolls Royce engine!. Now let's start but, if it's the first time you come here on Ingegneria Italia, we invite you to subscribe to the channel and activate the bell to stay up to date on the latest news in the world of engineering, just think that we also have a whole playlist of videos made within Italian companies. Great, and now let's get the ball rolling!! On this channel we have spoken little up to now about aeronautical engines, how they work and above all about the various categories of existing engines. The very first distinction that must be made when talking about engines is between Endoreattori and Esoreattori. The first, the Endoreactors, are made up of large tanks that store both the fuel and the comburent and without getting too technical, for those who don't know, during combustion what happens is that the fuel reacts with the comburent, usually oxygen, to produce heat, light and often other chemical products. The most obvious example is space rockets, such as SpaceX's Falcon 9 or ESA's Ariane V. These must necessarily carry the comburent, namely oxygen, since it cannot be found in space. The second family, the Exoreactors, are engines inside which.... #engine #aeronautics #engineering ???? What do we do besides dissemination?
