Annotation: The use of servo drives on flying vehicles determines the requirements to their dynamic characteristics. The problems of dynamics of drive with jet motor are not practically covered in publications. The task arises of selection of structure and parameters of devices consisting of several subsystems whose dynamic characteristics must be brought into agreement with each other in optimal way. The purpose of this work is to develop mathematical dependences for calculation of dynamic characteristics. The functional arrangement of the drive is considered consisting of jet motor based on Segner wheel with de Laval nozzle, mechanical transmission, pneumatic distributing device – jet pipe controlled by electromechanical converter. The layout is presented of mechanical segment of servo drive with jet motor with screw-nut transmission. The dynamic model is presented and the algebraic relations to determine natural frequencies of the drive are given. The motion equations of output rod at full composition of load are given. Using Lagrange transformation as applied to ball screw transmission, the expression for reduced mass of output element was derived. The reduced mass of load depends on the jet motor design and exerts basic influence on the drive’s natural frequencies. The evaluation is given of reduced mass change from the jet motor moment of inertia and reducer transmission coefficient. Based on the proposed algorithms, the dynamic characteristics of servo drive were constructed: transient process and amplitude-frequency characteristic. The drive has relatively low pass band, which is explained by the value of reduced mass of load.
Key words: pneumatic drive, functional arrangement, hydrodynamic force, reduced mass, Lagrange transformations, ball screw transmission, transient process, frequency characteristic

Annotation: The article describes the problems of manufacturing large-size nozzle blocks by classical for Ukrainian space industry method of high-temperature brazing. The Yuzhnoye SDO-selected way of solving this problem and the first strides on the way to organization of new production using innovative technologies of laser welding and surfacing are presented. The step-by-step sequence and procedure of research work to develop and test a new technology of cooled nozzle block manufacturing are described. Four phases are identified, out of which the first two phases have already been successfully performed. The laser welding and surfacing technology will allow avoiding the use of costly and unique equipment and will allow reducing and optimizing the technological manufacturing cycle rejecting the long –term and energy-consuming technological operations. The scientific-and-technological works performed showed the principle feasibility of making connection between the external jacket and internal wall of a nozzle block using laser welding. The test samples manufactured confirmed the high strength characteristics, which had been preliminary obtained by the theoretical calculation methods. The sections obtained by surfacing demonstrate good metallurgical connection between the layers. On the test samples, the technique was tried-out allowing repairing defect areas in a welded seam obtained by laser welding method. This is especially important from the technological and economic viewpoints, as the technology of high-temperature brazing applied currently does not allow making guaranteed repair of brazed joints.
Key words: liquid rocket engine nozzles, laser, laser welding, laser surfacing

Annotation: The article presents the experience of the first liquid rocket engine parts developing and manufacturing by means of additive technologies. Application of these technologies imposes new constraints on parts configuration, which are necessary to be considered by a designer. At the same time, application of additive technologies provides new opportunities to a developer, which are absent at traditional method of manufacturing. The article presents the results of manufacturing in Yuzhnoye SDO the first commodity parts, manufactured by additive technologies – selective laser melting, using SLM280HL 3D- printer with building volume dimensions of 280x280x350 mm. The obtained experience in the first liquid rocket engine parts developing and manufacturing by means of additive technologies has shown, that application of this technology allows manufacturing the parts having high characteristics at minimum terms and cost of preproduction, however for all potential opportunities realization, especially at implementation phase, it is necessary to change designing philosophy, which will require more working hours at designing. The obtained first results conclusively prove efficiency and expediency of additive technologies application at certain segment of liquid rocket engine parts manufacturing, at that it is clear, that manufacturing equipment improvement and design methods evolution will lead to steady expansion of this segment.

Annotation: The Ukrainian companies Yuzhnoye SDO and SE PA YMZ supply VG143 main engine assembly for Vega LV AVUM upper stage, which is a one-chamber LRE of 250 kg thrust with five ignitions in flight. By the present, 11 successful launches of Vega LV have been made. In the process of flight operation, there were no critical comments on engines operation. This LRE has a combination of attractive characteristics, such as high specific pulse, low mass, multiple ignitions in flight, high reliability confirmed by good results of flight test of the prototype engines. The reserve of this engine from the viewpoint of further modernization is far from being exhausted. Enhancing the capabilities of payload injection by launch vehicles into various orbits of artificial Earth satellites is the main task for the developers of ILV as a whole and for the developers of separate assemblies and systems, such as LRE being part of ILV. With consideration for the experience of prototype engines testing, we should note the following ways of main engine assembly modernization: – increasing the specific pulse due to the increase of nozzle expansion ratio; – decreasing the volume of internal manifolds and mass of chamber; – increasing the operation time; – increasing the ignitions number; – increasing the duration of pauses between ignitions and orbital functioning time. Increasing the thrust and specific pulse of Vega LV VG143 main engine assembly and AVUM stage takes place due to the use of pneumopump propellant feeding system instead of standard pressure feeding. Besides, the information is presented on RD859, RD864, RD866 and RD869 prototype engines, the data on their basic characteristics, testing and operation. The below information is of interest to LRE and LV developers.
Key words: main engine assembly, liquid rocket engine, ways of modernization, engine chamber

Annotation: The process of introducing new technologies at Yuzhnoye SDO requires major changes of aerospace products designing methods and project management methods, which allows realizing new opportunities, reducing manufacturing expenses with simultaneous increase of products quality. New software products are presented directed at solving the problems identified when using additive technologies at Yuzhnoye SDO. Such as Autodesk Netfabb, AM Process Simulation, ESI Additive Manufacturing and others that allow optimizing the model for additive technologies through the change of material structure, taking into account and compensation of heat setting during printing propose the tools for creating bionic design. Creation of new technologies of producing cooled nozzle block of LRE chamber without soldering became possible due to integrated approach, with optimal combination of already existing technical solutions with principally new ones, such as laser welding and surfacing. The cost analysis is considered as the most effective optimization method at selection of optimal design and manufacturing technology for its possible implementation at the company. The personnel problem, the issues of quality improvement and labor productivity increase in all production phases are foundational to reduce manufacturing cost.
Key words: additive technologies, software products, optimization, quality

Annotation: This article considers essentially new versions of small-sized solid propellant rocket engines (SRE), designed for rocket and spacecraft flight control with serial artillery pyroxiline powder taken as grain and solidpropellant gas generators discretely operating into the receiver. Preliminary results of design and experimental activities, performed in Yuzhnoye SDO, showed the possibility in principle and practicability to develop two new types of advanced small-sized SRE. Testing SRE with pyroxiline powder grain showed that the optimum design of the engine can be developed only with the application of the specially developed design procedure of the gas-dynamic flow pattern of powder gases in the engine chamber with definition of field of pressure and velocity. Such procedure has been developed based on Ansys software package. The article describes areas of further design and experimental activities, fulfilment of which will provide development of production models of the described engines. Intraballistic characteristics design procedure, mentioned in the article, can be used to design new type of micropulse SRE with less than 0.1 s burn time. This article will also facilitate definition of the application area for discrete solid-propellant propulsion systems, where they get the edge over the cold gas gas-jet systems.
Key words: procedure, microSRE, gas-jet system, heat-transfer factor
