Polish Tilt-Wing Projects

[Petrus]

In the late 1950s an attempt to build a tilt-wing transport aircraft was undertaken in Poland. Its designation was the PS-3 (for "Pionowy Start" in Polish, which means Vertical Take-Off). Of course the project never went off the drawing board.

Here is its drawing, in which you may see the airplane's dimensions. The PS-2 was to be propelled by two indigenous Tur 1000-hp turbo-prop engines (the engines were never built as well).

Best regards,
Piotr

The drawing comes from a book "Wiropłaty w Polsce" by Ryszard Witkowski, published in the early 1980s.

And I owe you a correction. The PS-2 was to have FOUR engines, not two as I have written. Each of its rotors was to be propelled by a pair of the Tur engines.
