Teh Джункерс Цзю 86 был немецкий моноплан бомбардировщик и гражданский авиалайнер, разработанный в начале 1930-х годов, и используется различными военно-воздушными силами с обеих сторон во время Второй мировой войны. Гражданская модель Ju 86B могла перевозить десять пассажиров. Два из них были доставлены в Swissair, а пять - в Deutsche Luft Hansa. Кроме того, в шведский AB Aerotransport был доставлен один гражданский Ju 86.

A Tale of Two Engines
Teh Джункерс Джу 86 К-4 represents a specific and successful export chapter of the Ju 86 family. While the standard German Luftwaffe versions were originally designed with the temperamental Jumo diesel engines, the K-4 (Export version for Sweden) utilized reliable air-cooled radial engines. Sold to Sweden and designated as the B 3, these aircraft proved significantly more dependable than their German counterparts and served as the backbone of the Swedish Air Force’s bomber fleet throughout the Second World War.

Design and Engineering: The Radial Shift
- The Move to Radials: Unlike the Ju 86A and D models used by Germany which suffered from diesel engine failures, the K-4 swapped the liquid-cooled Jumo diesels for Bristol Pegasus radials. This change required a redesign of the engine nacelles but vastly improved reliability and maintenance in cold climates.
- Dustpan Retractable Turret: The Ju 86 featured a unique ventral gunner’s station nicknamed the “dustpan.” This turret was lowered from the belly of the aircraft during combat to provide downward defense and retracted to reduce drag during cruising.
- Double-Wing (Doppelflügel): Like many Junkers designs (notably the Ju 52), the Ju 86 utilized the Junkers “double-wing” auxiliary flaps. These acted as separate control surfaces set just behind and below the trailing edge of the main wing, providing excellent low-speed lift and handling.
- All-Metal Smooth Skin: Moving away from the classic Junkers corrugated skin (seen on the Ju 52), the Ju 86 used a modern smooth duralumin stressed-skin construction to improve aerodynamics.
The Swedish Service (SAAB Era)
- License Production: Sweden was so impressed with the K-4 that the newly formed company СААБ was commissioned to build the aircraft under license. This was a foundational project for SAAB’s future as an aerospace giant.
- The “Long-Nosed” B 3C: Later Swedish versions (B 3C and B 3D) featured more powerful engines and a slightly modified airframe, remaining in service for transport and target-towing long after the war ended.
- Survivors: Because Sweden remained neutral, their Ju 86s were not destroyed in combat. The world’s only complete surviving Ju 86 is a Swedish-built K-4 (B 3C) preserved at the Swedish Air Force Museum in Linköping.
