Statistical testing of dynamic model identification procedure for gas turbine diagnosis
This paper is devoted to such a challenging problem as gas turbine model identification. A dynamic model identification procedure developed and proposed as a diagnostic tool is examined. A statistical verification of the ...
Optical emission spectroscopy measurements on a SPT-20 hall effect thruster on the RHAI ground test facility
The plasma plume of a SPT-20 has been analysed by Optical Emission Spectroscopy in order to analyse the emission of XeI, XeII and Al I emitted from the Al2O2 ceramic walls.
Numerical simulation of laminated plastics pulse riveting process
The list of existent problems within the limits of considered process is brought; the aim and tasks to perform is described; the analysis and analytical model type, the geometrical, physics-mechanical, finite element and ...
Efficiency improvements of batch production of sheet parts with method of electrohydroimpulse forming
Analysis of influences of main factors that determine efficiency of sheet-forming production: manufacturing, organizational, designing factors, is performed. Analysis of constituents of piece and piece-calculation times ...
Smart vibratory sensor for compressor surge control
Fast response piezoceramic sensor with embedded microchip device development and testing is resulted. Sensor was designed for flow instability modes detection in gas-turbine engine passages by means of its outer casing ...

Pressure feed with gas generator upper stage engine for a hypersonic suborbital cube-sat launch vehicle and sounding rocket «Shivastra-1»
An increasing trend, Low cost space access with Microsatellites, and so the need of an efficient, simple, reliable equally cost effective Carrier was considered with rapid designing and fast prototyping design concept so ...
Definition of models to determine the gas temperature at the inlet of the turbine's rotor in a life-time monitoring system
A life-time monitoring system is developed to predict the life-time of engines used in a gas pumping station. Four different models are presented to calculate the gas temperature at the inlet of the turbine’s rotor, all ...
Energy depozition and sufrace analysis of the SPT20-M17 hall effect thruster
As a way to analyse the plasma-wall interaction, the electron energy deposition has been calculated at different points of the ceramics delimiting the plasma discharge of a Hall effect thrusters. The calculation takes into ...
Development concept of jet engines for the unmanned aerial vehicles
Based on published open sources, analyzed the problems solved by unmanned aerial vehicles (UAVs) and applied them to the types of gas turbine engines. Designing engine for the UAV can perform «from scratch» in designing a ...
