Reduction in heat density of microturbine’s regenerator for autonomous power supply of agricultural production
Abstract
A method for reduction of heat density of frame of microturbine’s disk regenerator for autonomous power supply of agricultural production is considered. Distribution of temperature and other parameters in construction is calculated. Using of disk regenerator, that has higher thermal effectiveness in comparison with currently applied recuperators, will provide prominent decrease in fuel consumption of microturbine.

Selection of rational parameters for blade rotary working organ on the basis of its kinematic analysis
Abstract
On the basis of kinematic analysis of blade rotary working organ, dependencies of cutting angle of arbitrary surface element of blade on rotation angle of working organ and on its operation mode are determined. Recommendations for selection of working organ parameters are given, in order to decrease in specific energy consumption on soil treatment and to improve its quality.
