An-74T-200, a new generation light multipurpose aircraft, is designed to transport cargo and equipment and intended for local and middle range routes. An-74T-200 can also be used to transport passengers and paratroopers as well as for parachuting cargoes and transporting patients when converted to an ambulance version. An-74T-200 corresponds to civil aviation airworthiness standards set for a basic An-74 model. An-74T-200 is a modification of An-74 with the equipment reinstalled in order to decrease the number of crew members to four persons. In An-74T-200 the work places of radio operator and hydrologists and blisters of navigator and hydrologists were taken out, and a service room was equipped instead. It is provided with kitchen and galley, a toilet, niche for a folding ladder door, flight attendant's seat, oven, water heaters, containers, etc. An-74T-200 has 26 double-seat blocks of passenger chairs, 13 on each side of the aircraft, which can be easily folded and lifted up if an aircraft operator needs to convert the aircraft into the cargo one. 14 luggage racks, 7 on each side of the aircraft, are located above the passenger seats can be folded and lifted in the same fashion.
An-74T-200 can be converted from cargo to passenger airplane and vice versa at any off-base airfield quickly and easily. An-74T-200 features 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.
The dimensions of An-74T-100 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 any other modification 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 three persons: captain, co-pilot/navigator and a technician but can also be piloted by just two people, a captain and a co-pilot. The pilot cabin can also be completed with one more seat for a pilot if required by an aircraft operator.
