Systems for prevention of surging of centrifugal compressors and methods of rotating stall detection and early surge diagnosis
using statistical processing of sensor signals of various parameters, i.e., the method of calculation of the correlation function
of the signal and the method of calculation of signal dispersion, are discussed. The results of routine tests of air and high-speed
air centrifugal compressors and their detachable flow parts are adduced.

Problems that have arisen during tune-up of the production line for the thermal processing of solid household waste by the
method of burning in a vortical fluidized bed (principally, a new technology for Russia), and means of their solution are
presented. Investigative studies are cited.

The paper reports the experimental investigation data for the effect that nonparallel faces of bars under impact exert on
the parameters of longitudinal and bending strain waves generated in the bars. The changes in stress magnitudes in the bar
under impact with growing angle of the impact faces offset are described.

The temperature dependences of internal friction (ultrasound decrement) and impact toughness of bcc metals (Fe-12Cr-W-V-Ta-B-C ferritic/martensitic steel, V-4Ti-4Cr vanadium-based alloy) have been studied in a temperature range from 100 to 300 K. The acoustic and mechanical characteristics exhibit correlated variation. The use of nondestructive acoustic techniques for the investigation of mechanisms of the brittle-ductile transition in metallic structural materials is experimentally justified. 相似文献

Within framework of the continual fracture mechanics, we describe the engineering approach to the assessment of scattered
microdamage accumulation kinetics in metallic materials under elastoplastic loading conditions in case of plane stressed state.
Automatized experimental stand and the respective investigation technique are discussed. The stand has been developed based
on modification of the UMé-10T electromechanic test machine. State-of-the-art computer technologies and microprocessing hardware
are incorporated in the stand automation. We present the technique of experimental assessment of damage accumulation kinetics
in metallic structural materials under complex elastoplastic loading conditions with account of two different fracture (cleavage
and shear) processes, which technique is based on measuring the specific electric resistance of the specimen.

The research on magnesium alloys for structural lightweight applications is today at an embryonic stage, but these alloys
offer great potential. Thixomolding of magnesium alloys for automotive applications is promising since the process can be
used to manufacture net-shape parts cost-effectively and with high reliability and repeatability. 相似文献

Studies conducted on two power-generating units at the Kharanorskaya SAPP relative to the steam-water-oxygen passivation,
preservation, and partial cleaning of all boiler-heating surfaces, including the surfaces of the reheater, and passivation
of the surfaces of the high-pressure heaters on the steam and water sides by the steam-oxygen method, as well as partial passivation,
preservation, and cleaning of turbine blading are presented.

Measures taken to develop and put into operation three new exterior channels for emergency process water with two additional
60VTs pumping units, which remain operational even during an earthquake and were installed in the second block pumping station,
are described. In addition, the three existing 12NDS horizontal pumping units were used as a basis to develop a third channel
for the emergency process water. Above-ground water ducts with thermal insulation and heating systems to prevent freezing
during the anticipation state, which is the constant state of the emergency system, were laid.
As a result of upgrading with the development of three channels, the emergency process water feeding reached an adequately
safe level of reliability.

The main technical measures for increasing the nominal safety of the No. 5 unit of the Kursk nuclear power plant are presented:
optimization of the neutron-physical characteristics of the core, adoption of a comprehensive monitoring, control, and protection
system, switching to cluster-type control rods, adoption of a system for limiting radioactive emissions during anticipated
accidents with pipeline rupture outside the containment system.
