The AI-22 was developed in the 1990s and is designed for the
Tupolev Tu-324 regional airliner. The engine is based on a gas generator version of the
DV-2 engine. It has a
modular 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. •
KMPO 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. •
KAPO 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 ==
