Increasing the efficiency of rocket and space technology units by developing new and improving existing methods of space-complex design of aircraft structures and modeling of working processes in rocket engines
popup.description2
The following scientific results were obtained as a result of the research work:
1) The design parameters of the aircraft were determined, an algorithm was developed and a program was compiled to solve the problem of optimizing the characteristics of the aircraft - achieving maximum flight range at minimum altitude and minimizing the relative mass of the fuel.
2) A study was conducted on the choice of material for the rocket fairing, an analysis of the design and materials of the rocket fairing was carried out. A model was developed and studies were carried out on the behavior of the rocket cone when applying a heat flux.
3) A methodology has been developed and equipment has been designed for an experimental study of the phenomenon of self-excitation of high-frequency pressure oscillations in a model chamber with a gas-dynamic simulator of the combustion zone.
4) A criterial analysis apparatus has been developed for deterministic obtaining of intraspecific comparative assessments, selection of samples by functional groups, identification of the closest analogues of guided missiles according to given performance characteristics.
5) Based on mathematical models of defects associated with the parameters of the formation mode of a cellular packet, the reason for the appearance of technological deflection was identified and the corresponding tolerance fields for it were justified.
The practical significance of the developed issues is determined by the possibility of radically improving the quality of design of rocket and space technology units under conditions of steadily increasing resource constraints.
