Ilyushin IL-76MD-90A (IL-476) Aircraft, Russian Federation
Ilyushin IL-76MD-90A is a new military transport aircraft (code name: IL-476) developed by Ilyushin Aviation Complex, a subsidiary of United Aircraft Corporation (UAC). It is a modernised version of the IL-76MD which itself is based on the IL-76 cargo aircraft platform.
The IL-76MD-90A cargo aircraft is manufactured at the Aviastar-SP production facility in Ulyanovsk. The factory test flight of the first IL-76MD-90A was concluded in January 2013.
The aircraft successfully completed its maiden flight test in March 2013, near Moscow. It flew at altitudes of 2,000m to 10,000m for a period of one hour and 55 minutes during the test flight.
The flight test programme of IL-76MD-90A is expected to conclude by the third quarter of 2014.
IL-76MD-90A is developed to transport a range of military equipment, armed personnel, heavy and long size vehicles and cargoes. It will also be used in parachuting cargo / troops and other air borne cargo missions.
Orders and deliveries of the Russian military transport aircraft
The Russian Ministry of Defence (MoD) signed a $4bn contract with UAC for the delivery of 39 IL-76MD-90A aircraft, in October 2012. The deliveries are scheduled to commence in 2014.
IL-76MD-90A design, based on the IL-76
The IL-76MD-90A is based on the same airframe and fuselage of IL-76 aircraft. The cargo aircraft integrates advanced features such as redesigned wing section, new cockpit with modern avionics and powerful engines.
The aircraft has a length of 46.6m, height of 14.76m, wing span of 50.50m and a wing area (trapezoidal) of 300m². The landing gear track (outer wheels) and fuselage mid-section diameter of the aircraft are 8.16m and 4.8m respectively.
The IL-76MD-90A has a maximum take-off weight of 210t and can carry a maximum payload of 52t. It can accommodate up to five crew members.
Cockpit and avionics of the Ilyushin aircraft
The advanced glass cockpit of the IL-76MD-90A is installed with three intelligent control panels and a KSEIS-KN-76 aircraft status master monitor display system with eight multifunctional liquid crystal displays. The glass cabin provides better view to the cabin crew.
The IL-76MD-90A also integrates a digital ACS-76 auto flight control system and a new Kupol-III-76M flight sight navigation system with a display indication.
IL-76MD-90A cargo handling capabilities
The cargo cabin of the aircraft is designed with a length of 24.5m (with ramp), width of 3.45m, and height of 3.4m. The cargo cabin offers an interior volume of 321m³.
Il-76MD-90A is capable of carrying 126 parachutists or 145 troops in single deck arrangement and 225 troops in double-deck arrangement. It can also be installed with special equipment to carry 114 injured persons.
The aircraft is installed with an Aerial-Delivery System (ADS) for dropping of cargoes, transportation of armed forces cargo containers and pallets, and troop parachutes.
The ADS installed onboard the IL-76MD-90A facilitates dropping of parachutists from an altitude of 8,000m at 220km/h to 400km/h speeds. It also enables equipment dropping with the help of parachutes from altitudes of 300m to 4,000m at 260km/h to 400km/h speeds.
The cargo dropping system aboard the aircraft ensures the dropping of platforms laden with shipments and equipment. The under-ladder devices, roller ways and winches in the cabin allow the loading of cargoes and equipment into the aircraft.
Engine of Russia's Ilyushin military cargo aircraft
IL-76MD-90A is installed with four fourth generation PS-90A-76 turbofan bypass engines with 4:4 bypass ratios. Each engine develops a maximum continuous thrust of 14,500kgf. It consumes 12% lesser fuel and offers an increased flight range of 18%.
The PS-90A-76 engine on board the IL-76MD-90A aircraft is compliant with latest ICAO requirements for noise and emission levels. An Auxiliary Power Unit (APU) TA-12A is installed onboard the aircraft.
Performance of the IL-76MD-90A
The aircraft can cruise at a speed of 820-850km/h. It can fly at a maximum altitude of 12,000m. The maximum range of the aircraft is 8,500km. The aircraft requires 1,700m take-off distance on concrete runway.
The life expectancy of the IL-76MD-90A military transport aircraft is 30 years. The aircraft can accumulate a maximum of 30,000 flying hours throughout its service life.
The An-124 Ruslan (Nato reporting name Condor), designed by the Antonov ASTC, based in Kiev, Ukraine, is a very large cargo transport aircraft.
The Ilyushin IL-78 air-to-air refuelling tanker aircraft is a four-engine tanker principally used for in-flight refuelling. It was designed and developed on the basis of a similar predecessor, the IL-76, and has the Nato reporting name Midas.
