Guest Posted January 21, 2019 Share Posted January 21, 2019 World's Largest Commerical Turboprop, The Antonov An-22 Dec 7, 2017 by Nigel Howarth in Things With Wings There are only a handful of Antonov An-22s flying these days, and only one in commercial service, operated by Ukraine-based Antonov Design Bureau. Wherever it goes in the world, it generates a a lot of local interest, due to its rarity, size and noise. This past week, it visited Manchester Airport twice, initially to take a spare engine out to Holguin, Cuba, to rescue a stranded Thomas Cook Airways A330 which had blown a compressor blade. It then returned with the damaged Rolls-Royce Trent 772 engine, and finally departed empty to Leipzig, Germany, to await its next charter. The giant An-22 lifts off runway 23Right, dwarfing the A320 on the terminal. The turboprop-powered behemoth is so large, that a double-decker Airbus A380, the world's largest airliner, doesn't look that big any more ! With its 8 contra-rotating props on 4 giant engines, the An-22 departs Manchester, and who knows when it will return ? It's last visit was 13 years ago.... Photos: Nigel Howarth.

blues deville Posted January 21, 2019 Share Posted January 21, 2019 Makes the A380 look like a beauty queen. Link to comment Share on other sites More sharing options...
vanishing point Posted January 21, 2019 Share Posted January 21, 2019 The Russians seem to favour function over form in aircraft design. They get the job done. Link to comment Share on other sites More sharing options...
blues deville Posted January 21, 2019 Share Posted January 21, 2019 100% on the function. If you ever have a chance to see a true Russian made aircraft up close you immediately notice the differences in design, selection of materials and quality of workmanship from what we are use to in the west.

Why wouldn't they? It helped push back the Germans in WW2. They functioned on large quantities of low grade equipment vs smaller #'s of quality equipment. The Germans made amazing tanks. Their engineers and factories designed and built transmissions for tanks that would last +2 years before work was needed. Too bad the average life of a main battle tank was less than 6 weeks.

I think it was Josef Stalin that said something to the effect of quantity is a quality all on its own. Link to comment Share on other sites More sharing options...
