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.
First experienced the upgraded transport plane Sludge-76MD-90A built an aircraft factory “Aviastar-SP”Ulyanovsk and preparing for flight tests.
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-78M-90A Aerial Refuelling Tanker
The Il-78M-90A aerial refuelling aircraft is 46.6m-long, 14.76m-high, and has a maximum take-off weight (MTOW) of 220t. Its payload capacity has been increased to transport large volumes of fuel.
The wing assembly has been modified to incorporate two modern fuel tanks with a total capacity of 111,940l. The wing area and wing spans are 300m² and 50.5m respectively. The tanker accommodates six flight crew members.
The fuselage has a diameter of 4.8m and is configured to carry approximately 50,300l of fuel, while a large cargo ramp at the rear enables airdropping. The modular airframe can be converted to support other roles such as fire-fighting and cargo transportation.
The aircraft is outfitted with reinforced nose and main landing gear to support the increased maximum take-off weight (MTOW).
Refuelling capabilities of Il-78M-90A tanker
The Il-78M-90A refuelling aircraft carries a total of three UPAZ-1M hose and drogue aerial refuelling pods, two of which are mounted on the main wings and the remaining on the right side of rear fuselage. The fuel transfer capability of the UPAZ-1M pod is between 2,300l and 3,000l per minute.
Aerial-refueling system UPAZ-1M
Currently “RD&PE Zvezda” JSC designs and develops a unified aerial-refueling pod (UPAZ-1M) featuring an improved performance. The UPAZ-1М is to be mounted on the IL-78М-90А tanker.
The UPAZ-1М will support aerial refueling of the long-range, front-line and special aircraft equipped with aerial fuel-reception systems.
UPAZ-1 pod – redsamovar.com
In comparison with earlier developed items (UPAZ,UPAZ-1), the UPAZ-1М has a higher pumping capacity (up to 3000 l/min) owing to introduction of the ТNА-150М turbo-pump assembly with a higher power turbine. It is planned to complement the UPAZ-1М with an electrically driven pumping station, an angular movement transducer and a fire alarm system, SОP-62.
In the UPAZ-1М, the automatics control system is supported by the BАI (Automatics & Data Unit). Application of the BАI, which is being created on the basis of a modern domestic processor, makes it feasible to:
- realize flexible adjustment of the UPAZ-1М operation algorithms by the BАI reprogramming;
- obtain digital channels for data exchange with aircraft systems and checkout equipment using any interfaces currently applied in the aircraft;
- equip the UPAZ-1М with a self-contained recorder to register the pod’s performance characteristics both in flight and during maintenance on ground.
In future, application of the BАI in the UPАZ-1М will make feasible an automatic system to control the aerial refueling parameters. Source zvezda-npp.ru
The wing-mounted pods allow inflight refuelling of two frontline aircraft such as MiG-29/35 and Su-27/30/34/35 simultaneously using TNA-150M turbo-pump unit, while the rear-mounted pod allows for the refuelling of a long-range or special aviation aircraft.
The aircraft has the ability to refuel up to four aircraft simultaneously on land. Source airforce-technology.com

Russian Il-76 “Candid” Modified To Support Special Operations Conducts Flight Test Over The Black Sea: Here
A really interesting aircraft was spotted conducting flight testing over the Black Sea on Sept. 26, 2017: the Il-76MD-90A “78650”, the first “Candid” modified to carry out special operations.
According to the Russian media outlet “Izvestia” the example “78650” is a flying testbed for a heavily modified Il-76MD-90A variant equipped with “unique on-board radio-electronic systems that would allow the aircraft to stealthily deliver paratroopers and special forces behind the enemy lines, remaining invisible and invulnerable to the enemy.”
How the aircraft can evade radars and remain invisible is unclear, anyway, the experimental Candid can be distinguished from the baseline IL-76MD-90A by the presence of an opto-electronic station mounted on the lower nose section of the aircraft and for the “President-C” system used designed to protect aircraft from MANPADS (Man-Portable Air Defense Systems) and IR (heat-seeking) missiles by laser and radiofrequency/electronic jamming of the missile guidance.
Il-76MD-90A Aircraft to Combine Static and Endurance Tests
Russian Ministry of Industry & Trade has financed development of procedure for static and endurance tests of transport airplanes. It will be based on results of design audit over Il-76MD-90A aircraft and integrated into the R&D project codenamed Opora.
According to the R&D project documents available to Mil.Today, after transfer of production facilities from the Tashkent Aircraft Production Company to Ulyanovsk-based Aviastar-SP, “emerged the need for radically new procedure for structural tests that would ensure conducting both static and endurance tests at the same facility”. That must reduce the trials time and costs
As of today, an endurance specimen of upgraded Il-76 has passed fatigue tests in the extent of up to 2,000 flights. Additional calculations and experimental studies shall prove the design service life of 8,000 flights, says the R&D project description. It is planned to finish the tests by the end of 2019.
Mikhail Pestrakov, an aviation engineer and an airspace expert, confirmed to Mil.Today that the in-depth upgrade of the airplane needs new endurance tests and high-tech methods of their studying.
“The aircraft testing procedure must be adjusted in step with technology development”, the expert said
Gen Maj Alexander Akhlyustin, Russia’s honored military pilot of Il-76 aircraft added that due to production transfer the equipment and staff had changed, so assembly technology might change as well, which gave rise for extra tests.
New version of Il-76MD-90A transport aircraft differs from the predecessors by several parameters. The plane has ‘glass cockpit’, new communications and protection system, and new piloting and navigation equipment. Besides, it has more powerful engines PS-90A-76 thrusting up to 14.5 tons, which helps the airplane lift up to 60 tons payload.
