What engine was on the crashed plane?
In the day since the crash, it has not yet been officially announced which modification of the Il-76 the aircraft belongs to. Also, the preliminary causes of the engine failure that could have led to the fire and the tragedy have not yet been announced - the commission investigating the crash has not yet announced them.
However, it is known that all more than twenty modifications of the Il-76 have two types of engines. They are developed and manufactured in Russia and have completely domestic components.
The first option is the D-30KP engines, the very first for this type of aircraft, representatives of the family of turbofan dual-circuit engines for mainline passenger and transport aircraft. They were produced in Soviet times at factory No. 36 in Rybinsk, later it became known as NPO "Saturn", now it is PJSC "ODK-Saturn".
Characteristics of the D-30KP engine:
- take-off mode — Н=0, М=0, МСА;
- thrust (remains constant up to tн=+21°С) — 12,000 tons;
- maximum gas temperature in front of the turbine — 1,427K;
- cruising mode — Н=11 km М=0.8, МСА;
- thrust — 2,750 kg;
- specific fuel consumption — 0.7 kg/kgf h;
- bypass ratio — m=2.36.
Its weight without reverse is 2,305 kg, the length with reverse — 5,700 mm, and the fan diameter —1,455 mm.
Later, a modified version of D-30KP-2 was developed. It has much smaller dimensions: only 5448 x 1560 mm. The engine has:
- thrust in take-off mode — 12 tons;
- specific fuel consumption in take-off mode — 0.51 kg/kgf · h;
- specific fuel consumption in cruising mode — 0.71 kg/kgf · h;
- bypass ratio — m=2.24.
Another "heart" for the Il-76MD-90A and a number of other vessels are the PS-90A-76 engines from ODK-Aviadvigatel. They are developed on the basis of PS-90A - a turbofan dual-circuit low-noise engine.
Characteristics of the PS-90A-76 engine:
- thrust in take-off mode —16 tons;
- thrust in cruising mode — 3500 tons;
- specific fuel consumption —0.595 kg/kgf·h;
- flight altitude — up to 13,100 meters;
- bypass ratio — m=4.4;
- maximum gas temperature TSA — 1640K;
- start altitude in flight — 7,000 meters;
- air temperature at the ground for starting and operation — from –47 to.+45°C;
- altitude of airfields — up to 3500 meters.
In dry weight, the engine weighs 2950 kilograms, its delivery weight is 4300 kilograms. The PS-90A-76 is 4964 mm long, and its fan diameter is 1900 mm.
