Progress AI-22

The Progress AI-22 is a turbofan engine, developed by ZMKB Progress, Motor Sich JSC, KMPO and KAPO.

Development
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

 * Tupolev Tu-324 (proposed)
 * Yakovlev Yak-48 (proposed)
