Ilyushin IL-112T, Russian Federation
The Ilyushin IL-112T is a high-wing light transport aircraft being developed by Ilyushin Aviation Complex (JSC IL). Derived from the IL-114, the aircraft is being manufactured by Voronezh Aircraft Production Association.
The aircraft is capable of transporting a range of cargo, and can be operated from airports and unprepared runways. It can be operated by both military and civilian customers. The first IL-112 is expected to complete maiden flight in 2011.
The aircraft is offered in military IL-112V / IL-112B formats and an 11-seat corporate shuttle variants. The military version features a loading ramp. The IL-112V can carry a 6t-7t payload of military cargoes, equipment and personnel.
In May 2003, the Russian Air Force selected the IL-112V as its next-generation airlifter. The Russian Air Force requires over 70 aircraft of this type. The IL-112V will replace the 21t Antonov An-24 and the 24t An-26 aircraft currently in service with Russia.
IL-112 design and features
The IL-112T design is based on the IL-114 aircraft. The IL-112T retains cross section of the IL-114. The fuselage length was reduced by 6.2m.
The increased height and width of cabin results large cargo space for the storage of goods. The aircraft is powered by Klimov TV7-117 turboprops. Designed by traditional hi-plane scheme, its wings are equipped with mechanical flaps.
The aircraft is not suitable for short take-off and landing missions. The cargo hatch with thrust ramp on the rear side allows the loading and unloading operations.
The IL-112T is fitted with integrated airborne equipment. It has been designed to meet the ICAO noise and emissions standards.
The cabin of IL-112 accommodates two crew members. The total length of the cargo space including a ramp is 11.2m. The length of the area which is dedicated to store the goods reached up to 8.4m. The width of the floor load area is around 2.45m, of which the usable cargo space is up to 2.4m. The height of the cargo compartment is 2.4m.
The aircraft is being fitted with the integrated avionics suite, IKBO-112. The suite combines all components and subsystems in a single system. The aircraft can also be fitted with a custom avionics suite.
An electronic flight instrument system (EFIS) is equipped in the aircraft. The system includes primary flight display (PFD), multifunction display (MFD) / navigation display (ND), engine indications and crew alerting system (EICAS) / electronic centralised aircraft monitoring (ECAM). The flight information is displayed on six multifunctional liquid crystal displays. The avionics will allow the aircraft to perform tasks in any geographic and climatic conditions, day or night.
TV7-117ST turboprop engines
The aircraft is powered by two TV7-117ST turboprop engines, each of which develops a maximum propeller shaft power of 2800hp. Each engine drives a six-bladed propeller. The engine is produced jointly by Klimov JSC, Chernishov JSC and Baranov JSC. The TV7-117 series engines were also opted for the new Russian turboprop aircraft such as Mig-110 and Tu-136.
The fuel consumption of this engine is 500kg-550kg an hour. The TV7-117 engine increases the fuel efficiency of the aircraft by 2.4 times compared with the AN-26. The noise levels and emission of harmful substances comply with ICAO regulations.
The aircraft is equipped with conventional three-point landing gear. The retractable wheels are equipped with telescopic type shock-absorption system. The system provides stability to the aircraft when landing on synthetic or unprepared runways.
The IL-112 has a maximum cruise speed of 550km/h to 580km/h. It can fly at an altitude of 9,000m. The maximum take-off weight of the aircraft is 20t and the maximum payload is 6t. The aircraft has a range of 100km with a payload of 6t and 5,000km with a payload of 2t.
