The first jet plane was built in 1910 in Romania. Author - Henri Coanda. During the flight they opened an aerodynamic effect, which was subsequently named after him - Coanda effect. On the basis of this effect have been developed many projects of the aircraft "Zontolet", one of which was published in the journal "Technology of Youth."
I like to show students how to blow out a candle around a glass bottle to demonstrate the Coandă Effect. This is when a fluid (a substance that has no fixed shape and yields easily to external pressure; a gas or liquid) is attracted to a nearby surface. -Whoa, do I have enough breath left.
The next stage for airlines in engine efficiency and noise management is the geared turbofan, technology that is common on smaller jets but new to airliners. Pratt & Whitney's newest engines purport to solve the problem of possible gearbox breakdown on huge engines, something conservative airlines have feared despite the greater efficiency the technology offers.
