2000s Ukrainian/Russian turbofan aircraft engine
Progress AI-22
Type Turbofan
National origin Ukraine, Russia
Manufacturer ZMKB Progress, Motor Sich JSC, KMPO, KAPO
First run September 26, 2000
Developed from DV-2
Developed into AI-222

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
