PROCESS MODELING ELECTRO-HYDRAULIC CONTROL SYSTEM CANCELED OR RE-LAUNCH ROCKET ENGINE SOLID FUEL

Bachurin A.B., Strelnikov E.V., Tselischev V.A.

Abstract

Within the framework of the contemporary problem solving serial use of solid propulsion in space industry related disabilities deep traction control module and multiple on-off setting, proposed the introduction of a combined system of governance. The article provides a diagram of a controlled rocket propulsion system, equipped with a dual-circuit electrohydraulic control system, and describes how to control laid down in its foundation.The analysis of transients in a rocket engine solid fuel in separate and combined use of control subsystems responsible for the extinction of the engine and preparing to re-launch.

IMAGES OF CHAOS IN ATTITUDE DYNAMICS OF MULTI-SPIN SPACECRAFT AND GYROSTAT-SATELLITES

Doroshin A.V.

Abstract

Chaotic aspects of attitude motion of multi-spin spacecraft and gyrostat-satellites are investigated with the help of the Melnikov method and Poincaré sections. Images of dynamical chaos are plotted for some cases of phase portrait forms corresponded to different values of dynamical parameters. The bifurcations of the chaotic regimes with the change of phase portrait forms are illustrated.

THE INVESTIGATION OF THE STABILITY OF THE PROPELLANT INTAKE IN CARRIER ROCKET WITH MONOPROPELLANT ROCKET ENGINE

Diachenko M.I., Temnov A.N.

Abstract

The problem of propellant free oscillations in cylindrical and conical tanks is considered and solutions presented with boundary conditions on a free surface and the surface of intake which if speak figuratively provides a resistance to the fluid descent; the special attention was given to research influences the propellant intake on appearance Pogo effect. Such problems have come from the purpose to increase efficiency and output performance of the multistage cluster rockets by a central stage fueling from the side stages of a cluster.

Influence of the combustion process in the flow of fluidization fuel

Egorov A.G., Gagloev D.M., Tizilov A.S.

Abstract

Developed method of controlling the combustion process in the flow of fluidization fuel based on the injection of non-stationary jets of air into the mixing layer of the main flow to the recirculation zone. It is shown that by varying the frequency and the rate of injection of pulsating jets of air, you can control the characteristics of the combustion fuel in a stream of fluidization.

HYDRODYNAMICS AND CHARACTERISTICS OF PISTON PUMP WITH FLUIDIC DIODES

Khabarova D.F., Spiridonov E.K.

Abstract

The operational process of a piston pump with dampeners which valves are replaced by hydraulic semiconductors is researched. The calculation model for the complex stream flow in the pump flow-part under harmonic motion of a piston is proposed. Dependences of flow characteristic and pump efficiency are derived. The influence of pump parameters on its characteristics is analyzed. It is found that an increase of the piston relative square and diodicity causes flow characteristic boost. Valveless pump efficiency mainly depends on diodicity, diodicity increase causes efficiency boost.
