An-70
|
The Antonov An-70 can claim the title of being the world’s first propfan aircraft built. It was designed as a replacement aircraft for the four engined An-12 turboprop.
The program received a tremendous setback in 1995, when the first prototype collided with an other aircraft during a photo flight over the Ukraina. While the An-72 involved in the accident managed to return safely, the An-70 crashed and was completely destroyed. The second prototype, initially earmarked to become a static airframe for fatigue tests only, took to the air only by 1997.
The future of the program is closely observed as the An-70 might be the decisive milestone for its new propulsion technology. Performance and acceptance of the An-70 could decide whether propfan engines will spill over to manufacturers world wide or turn out to be the product of a dead-end road. |
