Another AN-72 Question From Mark

Wed Apr 05, 2000 12:50 am

OK, I'm still having a problem with this whole blown-flaps Coanda-effect thing.

All I ever hear is how wonderful it is and how great the short-field performance is...blah blah blah.

What's the downside? There has to be a reason that there's only one aircraft (the AN-72) using this configuration? What problems does this present that makes it undesirable or impractical?

Hi Mark,

Well iam afraid i can't answer your question however it came into my mind that the russians had several costly experiments on aviation stuff which was always found good (also by western experts) but never really went into mass production. Think of the Hydrowater stuff (you know the subject our friend Starship brought up last week) and of the TU154 which was operated by liquid gas instead of jetfuel...etc. All this stuff was maybe very genius but simply not practical enough to justify large scale production.

well, just my opinion
