AN-70 / Medium Military Transport STOL Aircraft
The AN-70 aircraft belongs to a new generation of the short takeoff and landing tactical military medium transports. AN-70 is extremely required by army. This aircraft is capable of solving qualitatively new tasks beyond possibilities of previous military transports. It was proved by the wide programme of the Joint State tests, main part of which had been completed. AN-70 can transport almost any item of aeromobile military and engineering vehicles used by armies of the world and to deliver them to poorly-equipped unpaved runways directly to the destination. On this ability, AN-70 surpasses all the existent airplanes.
AN-70 can perform the typical transport mission (transportation of 20 t payload at a range of 3000 km) from unpaved airfield of 600-800 m length only. There is no other airplane with such ability. Taking into account all likely possibilities it is possible to come to conclusion that the AN-70 STOL capabilities as much as twice reduce both the number of aircraft required for the mission and the cost of the operation. According to the design estimations, AN-70 can be operated from/to elevated airfields placed at altitudes up to 3000 m over sea level. In comparison with the analogues aircraft, the AN-70 can perform air dropping of cargoes and parachutists with twice less scatter and its crew can guide the aircraft to the calculated touchdown point with a pin-point accuracy.
Four D-27 engines with SV-27 counter-rotating propfans ensure a high cruising speed and 20-30% fuel economy in comparison with modern turbojet airplanes.
The built-in aerial delivery system ensures autonomous loading/unloading of a wide range of cargoes and their air dropping. The onboard loading equipment consists of four overhead rail electric motor hoists and two onboard electric winches. At customer request, the aircraft can be equipped with easily removable upper deck or roller conveyer to automate container handling operations.
Onboard monitoring and diagnostic systems make possible the autonomous operation of the AN-70 aircraft from poorly equipped airfields without the need for any special ground facilities. Aircraft maintenance is based on the “on-condition” strategy.
The AN-70 is fitted with modern electronic equipment and systems of fully digital control. The AN-70 is competitive enough as for the airframe and power pant characteristics as well as airborne system. The first production AN-70s constructed at ANTONOV Serial Plant will have modern configuration of electronic equipment.
In January 2015, the AN-70 was adopted by Armed Forces of Ukraine. At present, the aircraft is passing Special Tests programme.
