AN-74T-100

An-74T-100, a new generation light transport multipurpose aircraft designed by Antonov Scientific and Technical Complex, is a modification of the certified An-74. An-74T-100 was designed to transport cargoes and equipment at short and medium range air routes. AN-74T-100 aircraft meets the requirements of Civil Aircraft Airworthiness Standards, applicable to base aircraft AN-74. An-74T-100 has undergone the series of modernizations and improvements: thus, the cargo compartment was reequipped entirely (passenger, servicing and special equipment can was taken out), cargo handling equipment was modified because of the increased length of the cargo compartment, and the blister of hydrologist and navigator was taken out. In the pilot's cabin a seat of a radio operator was taken out and one additional seat for an operator of a cargo handling equipment was installed. Also because of the replacement of IKVSP-1-9M-U flight environment data system with IKVSP-1-9M-3 model, cockpit panels and consoles were also modernized. The installation of D-36 engines increased the takeoff weight to 36,500 kg, and payload - to 10,000 kg. An-74T-100 has become able to fly on international routes.

The aircraft is of 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.

Aircraft crew consists of four persons: captain, co-pilot, navigator, flight engineer and, if required, one cargo handling equipment operator. The aircraft can be operated without cargo handling equipment operator, in which case his duties are assigned to flight engineer.

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.
