Abstract

The resonant electric steering drive (RESD) can be applied as a part of control systems of all classes of rockets rotating on a list. Existing samples of RESD still far from perfect and their weight and dimensions are redundant. The purpose of this work is receiving a quantitative assessment of weight surplus of the best sample of RESD known now. In the course of work the problem of receiving a quantitative assessment of a stock of power and weight of the executive engine (EE) is solved. EE is the basic element of the drive defining its specific characteristics. Research is conducted by method of modeling of an operating cycle of the hypothetical guided missile. In this paper the questions of creation of the RESD imitating model which takes into account the thermal processes, occurring in EE and its research are considered. The model is created in the environment of Simulink entering into a mathematical MATLAB package. Models of entrance influences of the drive changing in time and loadings of its output link are constructed. The power stock of the EE was estimated at temperature of an overheat of windings and on energy of losses. The simulation results showed that the power of the EE in more than 10 times greater than those required output. It confirms that samples of RESD existing now possess the big excess weight and dimensions which can be significantly reduced at the expense of decrease in weight and dimensions of EE. The obtained results allow to carry out works in the direction of definition of extremely achievable specific characteristics of the steering drive at the present level of technology.
