Dornier Do 28
je oznaka tipa koja se sastoji od dva različita dvomotorna STOL komunalnih aviona, proizvedenih od strane nemačke kompanije Dornier Flugzeugbau GmbH. Većina njih je služila u nemačkom vazduhoplovstvu i Marinefliegeru i drugim vazduhoplovnim snagama širom sveta u ulozi komunikacija i komunalnih usluga. Serija Do 28 sastoji se od fundamentalno različitih Do 28 A / B (1959) i Do 28 D Skyservant (1966) .Izvor: Dornier Do-28 na Vikipediji

A Tale of Two Aircraft
Čaj Dornier Do 28 family is unique because the name covers two distinct airframes. The Do 28 A/B series was a direct twin-engine evolution of the high-wing Do 27. However, the Do 28 D Skyservant (which includes the B-1 variant in some nomenclature contexts, though typically B-1 refers to the streamlined earlier model) was a total redesign. The Skyservant became the definitive version: a boxy, rugged “flying truck” designed for Short Take-Off and Landing (STOL) operations. It was so reliable that German pilots affectionately nicknamed it the “Bauernadler” (Farmer’s Eagle).

Design and STOL Performance
- Unconventional Engine Layout: Unlike most twins, the engines are mounted on short stub-wing pylons attached to the lower fuselage. This keeps the center of gravity low, simplifies maintenance, and provides extra lift from the nacelles.
- High-Lift Devices: The wings feature full-span fixed leading-edge slats and large double-slotted Fowler flaps. This allows the Skyservant to lift off from “jungle strips” as short as 275 meters (900 ft).
- Rugged Landing Gear: The non-retractable tail-wheel undercarriage is built for rough, unprepared fields. The main gear struts are faired into the engine nacelle pylons for structural efficiency.
- The “Box” Fuselage: The Skyservant D-series moved to a rectangular cross-section, allowing for a flat floor and massive double doors on the port side, making it easy to load standard cargo pallets or oil drums.
Military and Special Roles
- German Military Service: The Luftwaffe and Marineflieger operated over 120 units for liaison, transport, and even maritime pollution control (equipped with Side-Looking Airborne Radar).
- The Israeli “Agur”: The Israeli Air Force used the Do 28 (naming it Agur, or Crane) extensively during the Yom Kippur War for light transport and reconnaissance.
- Air America: Small numbers of Do 28s were operated by the CIA-linked Air America in Southeast Asia, where their STOL performance allowed them to land at secretive, primitive “Lima Sites” in the mountains of Laos.
- Evolution into Turboprop: The airframe was so successful that it eventually evolved into the Dornier 128 and the much larger, highly popular Dornier 228.
