The Progress AI-22 is a turbofan engine, developed by ZMKB Progress, Motor Sich JSC, KMPO and KAPO.
Development
[edit]The AI-22 was developed in the 1990s and is designed for the Tupolev Tu-324 regional airliner.[1]
The engine is based on a gas generator version of the DV-2 engine.[2] It has a modular design consisting of 10 modules.[2] Materials and special coatings of parts allow the engine to operate in various climatic conditions.[2]
A successful start of a full-size engine was made on September 26, 2000.[2] Further development of the engine is suspended indefinitely.
Organisation
[edit]The AI-22 is created in a cooperation of four enterprises:
- ZMKB Progress is tasked with the manufacturing of external piping and cabling.[1] It also conducts tests and performs the final assembly of the engine.[1]
- 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.[1]
- 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.[1]
Emissions
[edit]The specific emissions of the engine during the landing and takeoff cycle are as follows:
