Operating principal is based on stepped variation of a throttle area at the vessel output (or/and input) using pulse code modulation. The control device is made as set of parallel on-off valves. Flow areas of the valves can be presented by binary dependencies of the smallest cross-section or by the Fibonacci series. The number of valves depends on control process accuracy. Simulation results show a good correlation with experimentally obtained data proving efficiency of the proposed control strategy to providing high accuracy and proper quality of transients.

Abstract

The results of strength and gas dynamic improvement of turbocharger TK-32 axial turbine are presented. Turbocharger is used as unit boost for diesel locomotive. The aim of this work was to ensure turbine work capacity when rotor speed is increased by 10% without efficiency reduction. The strain-stress state analysis indicated the region of high stresses on rotor blade body. These stresses exceed allowable values when rotor speed was increased.

The variant of peripheral rotor blade section displacement, allowing to reduce the level of stresses by 20%, was found. Gas dynamic calculation showed that variant of rotor blade modernization results in an increase of efficiency by 0.4%.
