Statistical testing of dynamic model identification procedure for gas turbine diagnosis
(ХАІ, 2003)
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
(ХАИ, 2006)
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.
