    Abstract An analysis of the operation of blades of gas turbine engines (GTE) manufactured from cast nickel alloys has made it possible to determine some of the causes of failure in operation, such as changes in the geometric dimensions or degradation of the microstructure. As a rule, the first cause is considered to be decisive. In order to increase the service life of blades partial regenerative repair of them is envisaged. In this case the dimensions of the blades are usually restored without allowing for possible changes in their structure, which can have a negative effect on operation after the restoration. For this reason, the second cause can become decisive in the reduction of their service life. This work is devoted to investigating the regularities of the degradation of the structure and properties of the material of cast GTE blades made of a high-temperature nickel alloy of the ZhS6U-VI type under operating conditions. A structural criterion determining the operating capacity of the olades and the ultimate level of structural degradation are established. A regenerative heat treatment to be conducted after partial exhaustion of the opet acing resource accompanied by structural changes that occur within the critical range of the structural criterion is suggested.

    Notes:
    Conclusions The conditions for the formation of a slag layer in an unlined and uncooled steel pipe were determined by methods of mathematical experiment design and on hot models. Within the investigated limits of variation of the factors the growth of the layer is governed by the degree of excess heating of the slag and its stay time in the pipe. The results of calculations of the thickness of the layer from the mathematical model constructed for this purpose agree very closely with the results of the industrial-scale experiment. An analysis of the mineral composition and melting point of four slags of the system CaO-Al2O3 showed that among the compositions investigated the slag lining approaching the composition of CaO-Al2O3 possesses the best combination of properties.

    Abstract One possible method is considered of deriving the well-posed (in the sense of A.N. Tikhonov) solutions to the problems of estimating the aircraft performance characteristics. The method is based on the results of measurements of the state parameters and geophysical conditions of the employment of the rocket-and-space facilities under conditions of uncertainty of the a priori data on measurement errors.

    Notes:
    The effective means of microbial culture monitoring is the measurement of low-inertial parameters (respiration rate, rates of supply of alkali for pH maintenance and the limiting substrate) and utilization of computer on line with fermenter for recalculation of these rates into the instant values of mass and energy cell yields, specific rates of cell growth and substrate and oxygen consumption, using the method of mass-energy balance. In this paper, the equations of mass-energy balance are presented both in general form and in the form of numerical algorythms for computer programming.The installation for automation of microbial cultivation experiment is described. Experimental data are presented which indicate the effectiveness of the method of indirect measurement of cell biomass yield and specific rates of physiological processes.
