Turbochargeris used as unit boost for diesel locomotive. The aim of this work was to ensure turbine work capacity when rotorspeed is increased by 10% without efficiency reduction. The strain-stress state analysis indicated the region of highstresses on rotor blade body. These stresses exceed allowable values when rotor speed was increased.</p>
<p>The variant of peripheral rotor blade section displacement, allowing to reduce the level of stresses by 20%, wasfound. Gas dynamic calculation showed that variant of rotor blade modernization results in an increase of efficiency by0.4%.</p>Turbochargerrotor wheelgas-dynamic analysisstress strain statethe load factorТурбокомпрессоррабочее колесогазодинамический анализнапряжённо-деформированное состояниекоэффициент запаса прочности
