Chromoaluminizing of cooled blades of gas turbines by circulation method

The process of chromoaluminizing of external and internal surfaces of cooled blades of gas turbine engines from refractory alloy ZhS6U is studied. The thicknesses, phase compositions, and chemical compositions of coatings deposited in a two-stage process by circulation and powder methods are compared. __________ Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 7, pp. 36–39, July, 2007.

Raising the accuracy of operative monitoring by using a variable pressure differential of the flow rate of material and energy carriers in the liquid and gaseous states

Means are considered for reducing the systematic errors in calculating the flow rate of material. For operative monitoring of the day- to- day flow rate, a comparative analysis is made of the numerical solution of the mass flow rate equation and the structure- generalized method for solving the equation.Translated from Izmeritel'naya Tekhnika, No. 5, pp. 37–39, May, 1994.     

Special features of failure of multilayered structures in local dynamic loading

The authors present the results of numerical modeling of penetration of a rigid indentor into multilayer barriers made of concrete, steel and sand. The effect of the material and the position of the layers on the penetration of a striker and failure of the barrier is analyzed.Translated from Problemy Prochnosti, No. 5, pp. 64–68, May, 1994.     

Perspective channel-type reactor with enhanced safety

Following the search for new design solutions to develop within the framework of channel trends the reactor with enhanced safety the Research and Development Institute of Power Engineering has developed the design of the multiloop boiling water reactor (MKER). The MKER enhanced safety is attained when involving the inherent safety features, passive safety systems as well as the accident consequences confinement devices. The design realizes several advantages which are typical of the channel-type reactors, namely: the design desintegration simplifying the manufacture, control, equipment delivery and decreasing, versus the pressure vessel reactors, the accident effect if it proceeds in an explosive manner; small operating reactivity margin and fuel burnup increased due to continuous refuelling; fuel cycle flexibility allowing comparatively easily to adopt the reactor to the conjuncture of the country fuel balance; multiloop circuit of the main coolant which reduces the degree and effect of the accidents connected with the equipment and pipings rupture; monitoring of the channels and fuel assemblies leak-tightness.
