The first successful rotorcraft (1) - PKZ-1

Helicopters are a common sight in today's sky, but the journey to them was much more complicated than in the case of airplanes. It is gratifying that a number of men born in the territory of the future Czechoslovakia took part in the development of the first motor aircraft capable of steady hanging.

The first successful rotorcraft (2) - PKZ-2

After the destruction of the PKZ-1 power unit, the engineer Žurovec decided to continue with the construction of the observation platform according to the original Petróczi design. In the meantime, large-diameter propellers were available - the results of the work of engineer Kármán at the propeller test institute. Nothing prevented the further development of the helicopter platform.
