Equivalent- cyclic testing of the AI-450C turboprop engine
The scheduled endurance equivalent-cyclic testing of the AI-450C turboprop is successfully completed at the Experimental Test Complex of SE Ivchenko-Progress. The testing was aimed to extend the service life before first overhaul and the assigned service life of all small-sized turboprop models developed on the basis of AI-450C.
Between April and June 2019, the engine passed more than 2,900 test cycles during which min. 495 hp and maximum values of all basic engine parameters envisaged by the test program, were maintained.
The attained test results together with earlier performed operations enable the specialist of SE Ivchenko-Progress to prepare and issue at the State Aviation Service of Ukraine the documents to extend the service life before first overhaul to more than 1,000 hours for all models of AI-450C, AI-450CD, AI-450CM, AI-450CP
