I have no idea what the Coanda effect is, but the placement of the engines on the AN-72 are definitely similar to the plane in the original post.

I didnt either so I looked it up, still dont understand it lol
The Coandă effect is a physical phenomenon in fluid mechanics that refers to the tendency of fluids, such as air or water, to adhere to a curved surface instead of following a straight path. This fluid dynamics phenomenon can be observed in various situations from the flight of an airplane to the operation of a steam turbine.
Think high pressure underneath and lower pressure above contributing to lift. It's not much different than Bernoulli's principle, used in lift, just uses a different shape and engine thrust as the high pressure fluid. Read the explanations on the AN-72 page, they are a bit simpler if I'm remembering correctly. STOL stuff is fun, my father's friend while I was growing up, had a Helio Courier that we would borrow. It was a blast taking off in the front yard, out in Piedmont. We actually had a grass strip in the backyard, but the Helio didn't need it, the take off and landing run was so short.
