Studies and Experimental Research in the Evaluation of TV2-117A Turboshaft Engine Working Regimes

The paper presents a detailed study of certain working regimes TV2-117A turboshaft engine, based on practical research using experimental data following the engine run tests. tests were made into test bench, hydraulic dynamometer to vary load free power turbine and measure main parameters, by operating dynamometer, different are obtained. To accomplish tests, execution an additional instrumentation was conducted and, through digital acquisition controller system, series parameters measured. concerned examination variation performances at various regimes, from idle (a) takeoff (b), including cruise (b) maximum continuous (c) presented actual values curve diagrams measured results in order create base comparison with manual.
