PZL-104 Wilga

The PZL -104 Wilga ( Golden Oriole ) is a single-engine aircraft of the Polish multi-purpose Państwowe Zakłady Lotnicze (State Aviation Works ) with STOL capability. It is used among other things as agricultural, medical, travel, towing and training aircraft.


The aircraft is a cantilever high -wing monoplane of all-metal semi- monocoque construction with planking. The non abgestrebte airfoil has a spar, slats and slotted flaps. As an airfoil is used throughout the inside and outside a NACA 2415. The rigid spur wheel landing gear is sprung ölpneumatisch and can be equipped with snow runners. The combination of good power to weight ratio, variable pitch propeller and aerodynamic lift devices allows the use of very short take-off and landing fields.


Predecessor was the PZL -101 Gawron ( Rook ), which was based in turn on the produced in Poland under license Yak- 12M. The first flight of the prototype took place on 24 April 1962.

The first production models were equipped with six - cylinder boxer engines and were produced under the name Wilga 2.

1967, the model has been revised and equipped with a 9-cylinder radial engine of Ivchenko Progress. This referred to as Wilga 35 type appeared in the largest quantities and first flew on 28 July 1967. Wilgas By 2008, 997 were produced and exported to 18 countries. India produced the aircraft as " Gelatik " under license.

In the GDR, 81 copies of the Wilga 35A version from 1971 were mainly used by the Society for Sport and Technology for parachute jumpers, as tow plane for gliders and precision flight championships. Two Wilgas flew in 1981 for a short time at the People's Police, five were used by the operating agricultural Flight of the Inter flight. As a single aircraft the Wilga was overpowered, but as a tow plane for up to two gliders they had excellent safety reserves in the engine performance. With the Wilga also isolated three single-seat gliders ( Troika drag ) can be dragged at events. Here, however, it reaches the limit. From its pilots, the aircraft was often referred to as aerodynamic crumb cake, the compensated all pertinent shortcomings with sheer engine power.
