The PZL-101 Gawron ( German rook ) is a Polish multi-purpose aircraft and a further development of the Soviet Jakowlew Jak-12 .
history
The PZL-101 is based on the previous model Jak-12M, of which 1054 units were built in the state aircraft factory in Warsaw-Okęcie from 1956 to 1960. Designed by a development group led by Stanisław Lassota, the prototype first flew on April 14, 1958. After the Jak-12 production ended, the PZL-101 went into series production from 1960. The biggest change compared to the Jak-12M is the simplified structure and the resulting increase in payload. Great importance was attached to keeping the very short take-off and landing distances required for the original model.
The PZL-101 was designed for various purposes, for example in the version G 1 with a rigid propeller as an agricultural aircraft with an 805 liter tank in the fuselage (215 pieces built) or, equipped with two stretchers, for patient transport (32 pieces). As a PZL-101 G 2 travel and liaison aircraft with an adjustable propeller and radio equipment (78 pieces built), it was able to carry three other people in addition to the pilot, but could also be converted into an agricultural variant. In the flying clubs it served as a tow plane for gliders . The freight version was able to transport a payload of up to 300 kg. The installation of a 90-liter additional tank increased the range to 1000 km.
In 1962, production of the improved PZL-101A began . In the same year, another improved version, known as the PZL-101B , took off for its maiden flight on March 9th. Of the total of 325 Gawrons manufactured, 143 aircraft were exported to ten countries. The PZL-101 is still used in flying clubs today.
construction
The PZL-101 is a braced shoulder wing aircraft with wings in a slight V-position and a 4.5 degree sweep. The fuselage structure consists of welded steel tubes, frames made of duralumin and fabric covering. The front fuselage area is metal-clad. The two-spar wing and the tail unit are also made of metal with fabric covering. The gawron is equipped with slats , split flaps and wing tips. The tail wheel landing gear is not retractable and has a pneumatic braking system. In winter the aircraft can be equipped with snow runners.
