design consisting of 10 modules. Materials and special coatings of parts allow the engine to operate in various climatic conditions. A successful start of a full-size engine was made on September 26, 2000. Further development of the engine is suspended indefinitely.

Organisation

The AI-22 is created in a cooperation of four enterprises: * ZMKB Progress is tasked with the manufacturing of external piping and cabling. It also conducts tests and performs the final assembly of the engine. * Motor Sich JSC is tasked with the manufacturing of the high-pressure compressor, combustion chamber, high-pressure turbine, air starter, air separator, start valve, air bypass valve, parts for piping, and fasteners used in the assembly of the engine. *

is tasked with the manufacturing of the low-pressure compressor and fan, the low-pressure turbine, middle and rear support, transmission units, engine mountings, and oil system units. *

is tasked with the manufacturing of the thrust reverser, jet nozzle, and cowlings.

Emissions

The specific emissions of the engine during the landing and takeoff cycle are as follows: *CO = 110 g/kN *HC = 12 g/kN *NOx = 45 g/kN *SN = 20 g/kN

Applications
