An-74TK-200, a new generation light transport multipurpose aircraft designed by Antonov Scientific and Technical Complex and produced by KSAMC, is a modification of the certified An-74 for Arctic and Antarctic. An-74TK-200 was designed to transport cargoes and equipment at short and medium range air routes. AN-74TK-200 aircraft meets the requirements of Civil Aircraft Airworthiness Standards, applicable to base aircraft AN-74. An-74TK-200 aircraft has a high wing design with two turbofan engines D-36, series 3-A. The engines are mounted over the wing and have thrust of 6500 kgf (63,7 kN) each. The aircraft has a Tee-tail assembly.
Mounting the engines high over the upper surface of the wing and shifting the engines forward prevent foreign object ingestion from the surface of a runway during take-off and landing. The aforementioned peculiarity also improves wing lift due to the blowing over of wing upper surface and inboard flaps by engine streams and reduces noise level at the terrain due to screening engine streams by the wing.
An-74TK-200 has a number of layout options so that the aircraft operator can choose, for instance: transporting 52 passengers; transporting 10 tons of cargo; transporting 20 passengers and 4.5 tons of cargo; transporting 12 passengers and 6 tons of cargo. The dimensions of An-74TK-200 cargo compartment were optimized in accordance with main kinds of transported cargo and allow transporting cargo in containers and packed on rigid pallets. The compartment also provides an opportunity to transport non-standard cargo (bales, barrels, etc.) and non-self propelled and self propelled wheeled materiel (automobiles of "UAZ", "RAF", "Jeep-C47" ARO-240, etc. types).
Cargo compartment of the aircraft can be converted into other envisaged versions by an operator within a very short time. Loading and unloading cargo, packed on pallets, cargo in containers and other kinds of cargo is done with airborne cargo handling device with lifting capacity of 2500 kgf (24,5 kN). Loading and unloading self propelled materiel is performed by its own motion, while non-self propelled wheeled materiel is loaded and unloaded with a towing tractor and cable cargo handling device.
High thrust-to-weight ratio, availability in the aircraft of auxiliary power unit for independent starting of the engines and cargo handling equipment, and high location of the engines and low-pressure tires provide autonomous operation of the aircraft from uncontrolled unpaved, pebble, ice and snow covered airfields.
Modern flight and navigation and radio communications equipment, mounted in the aircraft, provides aircraft flights in all geographic regions, over land and sea, in standard and adverse weather conditions, during day and night with high precision of navigation en-route and landing in the conditions of ICAO category I weather minimum (60x800 m).
The aircraft is simple to operate and can be easily mastered by flight and servicing personnel of average qualification. Aircraft crew consists of four persons: captain, co-pilot, navigator, and one cargo handling equipment operator for cargo aircraft or one steward for passenger aircraft.
