Procedure and test unit for studying the operating capacity of gas turbine engine blades under the combined action of mechanical and thermal loads,and atmosphere in a gas-dynamic test bed

A procedure and a gas-dynamic test bed are described for testing gas turbine engine blades with programmed mechanical and thermal loading. The test bed provides fatigue and heat resistance tests for GTE blades under conditions of the corrosive action of a high-temperature gas stream including variable thermodynamic parameters as well as other corrosive components, for example sea water salts injected into the stream in order to simulate GTE marine operating conditions.Deceased.Translated from Problemy Prochnosti, No. 6, pp. 71–77, June, 1993.
