The calculated study of fluid structure in a hub an axial aviation turbine
1 1., 1 1.
Abstract

The paper conducts comparison of gas torrent patterns in interblade channels of a turbine stage. Received in calculation by means of CFX program with the existent physical conceptions and experimental data. The calculated torrent structure matches well the given data, and allows to study secondary torrents in an axial turbine channel in detail.

Mathematical modelling and parametric research of flow of the twisted turbulent single-component stream of the propulsive mass in the trance- and supersonic areas of Laval nozzles
1 1., 1 1.
Abstract

With use of mathematical model of the space (twisted) viscous (turbulent) flow of a single-component propulsive mass in a trans-and supersonic areas on the basis of system of the equations of Nave-Stokes and the software of computer systems ANSYS CFX and STAR-CD CD-adapco, distribution of gasdynamic properties in Laval nozzles is gained and some regularity of such type of flows is determined.

Methodology complex of hardware-in-the-loop functional modelling of gas turbines and its systems
1 1., 1 1., 1 1., 1 1., 1 1.
Abstract

The problems of building of adequate structural complex gas turbine model for hardware-in-the-loop investigation of the automatic control system behavior with system faults are discussed. The structure and technology for creation of the adequate complex gas turbine model with an example of twin-shaft bypass reheat turbo jet for hardware-in-the-loop simulation, including a special complex of models of switching between operation and reconfiguration in FADEC control-and-condition-monitoring systems with system faults are offered.
