Historical information

Petróczy, Kármán and Žurovec were three Hungarian engineers who worked on helicopter development immediately before and during World War I. Between them they produced two experimental prototypes, the PKZ-1 and PKZ-2, intended to replace the dangerous hydrogen-filled observation balloons then in use.

The PKZ-2 was developed by Žurovec in parallel with the PKZ-1, but wholly independently. It had three radiating arms, each housing a rotary piston engine. These engines were coupled together to drive a central pair of co-axial, contra-rotating two-bladed wooden propellers or rotors, of 6 m diameter, mounted above the airframe. A round cockpit for the aircrew was fixed centrally, on top of the rotor mast. Landing gear again comprised rubber-fabric cushions, one large central one and three smaller ones at the end of each arm.
