Test cell enables testing jet engines of up to 15 000 daN thrust and of air flow demand of up to 150 kg/s. However, it is possible to reconstruct intakes and ejectors in order to accommodate engines with a higher air flow demand.

Air inlet - cross-section dimensions:

• width - 9,0 m
• hight - 10,0 m

Test chamber:

• length - 21,0 m
• width - 9,0 m
• highth - 10,0 m

Exhaust outlet:

• gas cooling and exhaust system - two steps ejector
• ejector diameter I step - 2,45 m
• ejector diameter II step - 4,547 m

• housed system. Duct length including two ejector steps - 33,45 m .
• secondary air sucked into II step ejector by two side inlets and ducts of 2,5 m x 9,0 m cross-section

Fuel system:

• fuel storage capacity - 4 x 100 m3
• pump station output - 20 000 kg/h
• instant fuel surge capability supported by supplementary pump system

AŁ21F3 engine test aerodynamic and acoustic parameters while afterburner of 11 200 daN and of 104 kg/s consumption is engaged:

• test chamber air flow - 616 kg/s
• test chamber pressure drop - 343 Pa
• engine flow round air speed - 4,7 m/s
• engine noise muffling from 172 dB(A) to 35 dB(A) at a distance of 300 m from the exhaust ejector and from 172 dB (A) to 60 dB(A) at the control room.
