10.12.2016: Stand for testing turbojet engines in CIAM


Central Institute of Aviation Motors (CIAM) named after P.I. Baranov, the leading scientific organization of Russian aircraft engines, presented the U-9M Stand for testing of aviation turbojet & turbojet two-loop engines and auxiliary power units in simulated altitude-climatic and altitude-speed conditions, as well as engine input elements in icing conditions.

 

Measuring and computing complex of the stand includes the LTR module DAQ system system based on the Blackfin processor type ADSP-BF537 and measuring modules that provide data acquisition and processing on steady and transient modes of the engine (up to 1080 channels) and control of technological equipment (up to 254 channels).

Types of engines testing:

  • determination of throttle and altitude-speed characteristics;
  • checking the stability of combustion in combustion chamber;
  • checking the start and acceleration in flight, checking the quality of ACS and on-board engine monitoring system;
  • checking the reliability of the lubrication and venting systems, etc.

The tests are carried out using the identified mathematical models, which ensure the test results taken to the specified values of the parameters corresponding to the simulated altitude and the Mach number. The models are based on the methodological principles adopted in the CIAM and implemented with the help of appropriate software packages.

Since 1997, 14 types of engines have been tested on the stand, from large turbojet two-circuit ones to auxiliary GTE, as well as 6 types of anti-icing alarms.
