History

2023: Creating material for 'invisible' aircraft

March 30, 2023 it became known about the creation in Russia of a unique stealth material for aircraft. We are talking about the development of the Central Design Bureau of Special Radio Materials (TsKB RM, part of Roselectronics, which, in turn, is part of Rostec).

According to the press service of Rostec, a fundamentally new material was developed at the Central Design Bureau of the Republic of Moldova, which allows absorbing radio waves in a wide frequency range. Thanks to the base of glass liners with a metal core, the thin-layer material can be used for manufacturing aircraft parts. Such a structural solution was proposed for stealth material for the first time, the state corporation said in a statement.

A fundamentally new material was developed at the Central Design Bureau of the Republic of Moldova, which allows absorbing radio waves in a wide frequency range

As the developers explain, in the process of creating a radio absorbing material, several layers of glass fabric were connected to each other. It is based on thin threads with a metal core in glass insulation. Due to its exceptional characteristics, the new material absorbs up to 95% of the incident electromagnetic radiation of radars and significantly complicates the detection of an air object using radar.

According to Alexei Dymovsky, General Director of the Central Design Bureau of the Republic of Moldova, the military aircraft industry has long been the problem of creating structural radio-absorbing material. Previously created types of stealth coatings of aircraft were required to be regularly restored, while fiberglass with a reduced reflection coefficient does not require maintenance.

Our prototypes have already successfully passed the necessary factory tests, "he said.

Rostec added that the stealth material created at the Central Design Bureau of the Republic of Moldova is intended for the manufacture of engine compressor blades - one of the most noticeable parts in the radio range.

2016

In 2016, TsKB RM develops, manufactures and supplies:

• radio-shielding and radio-absorbing materials for the purposes of camouflage, equipment of measuring echo-free cameras, meeting rooms, living quarters exposed to an increased level of high-frequency electromagnetic fields, overalls for operation under these conditions.
• optical and electrically conductive glue, compounds and sealants (including radio-absorbing and radio-shielding), materials and varnishes for providing moisture protection, microwave ceramics for REA, low-melting solder glasses, etc.

In addition:

• assesses the electromagnetic situation, makes recommendations on the selection of materials that ensure medical and biological safety and solve problems of electromagnetic compatibility and information protection.

The development of the RM Central Design Bureau meets the requirements of international standards and is at the level of development of leading companies in the world.

Since the creation of the Central Design Bureau of the Republic of Moldova, employees of the enterprise have completed more than 400 research and development work, created about 300 fundamentally new materials, many of which are made at the level of inventions, mastered in production and found use in various products of military and household appliances.

Many developments were awarded the State Prize and Prize of the Ministry of Defense of Russia, medals of VDNH, diplomas of foreign exhibitions.

2005

Creating a New Generation of Materials

In 2005, the Central Design Bureau of the Republic of Moldova participated in the implementation of a number of programs, the most important of which are:

• Presidential program "National technological base" in the direction of "Technology of new materials";
• Targeted comprehensive program for the creation of new materials until 2005;
• radio industry program for the creation of new materials for the needs of the national economy, defense and security.

In modern conditions, the Central Design Bureau of the Republic of Moldova focuses on the creation of a new generation of multifunctional materials with a high level of physical, physical, chemical and operational characteristics, as well as "intelligent" structural materials with controlled properties, effective materials for biotechnology, ecology and medicine, new intermetallic and ultra-dispersed materials and compositions, including special ceramics, glasses, compositions based on metal and metal oxide matrix systems.

The developed special microwave ceramic materials of the MT-20, BA-35, MT-60, T-90 grades, which are a system parametric series with a dielectric constant of 20 to 90, a tangent of the dielectric loss angle (2-5) 10-4, have found wide use as microcircuit substrates, bases of delay lines, resonators, capacitors, filters, which made it possible to reduce their mass and size dimensions by 1.5-2 times with a simultaneous increase in reliability and service life.

The creation of a new generation of computer technology is directly related to both the improvement of recording media and the creation of high-quality magnetic heads (MG) with high resolution, the stability and reliability of which depends on the physical, mechanical and electrophysical properties of the materials used. To implement new design solutions in the field of creating floating magnetic heads (PMG) for large-capacity drives (100, 200, 317 MB), the RM Central Design Bureau has developed and introduced special types of ceramics and glasses.

The main problem that arises when creating high-quality MG is the achievement of the required consistency of the physical and mechanical properties of all components of the structure (ceramic case, ferrite core, dielectric gasket, etc.).

Special materials were created by the design bureau to increase the resolution of the MG by 1.5 times, such as:

• ceramics of CCM brand for MG bases, synthesized in CaO-ZrO2 system, providing D14 surface cleanliness, high microhardness and wear resistance;
• refractory glasses synthesized in the SiO2- R2O3-RO system (KN-90 grade): spreading temperature 930 ° С; microhardness 8.5 GPa; coefficient of linear thermal expansion (100 ± 4) Ch10-7 1/° С; wetting angle ~ 11 deg; the width of the gap to be formed is 1.5 μm;
• low-melting glasses synthesized in the system PbO - SiO2 - B2O3 (brand SK-85); spreading temperature - 520оС; coefficient of linear thermal expansion (100 ± 4) Ch10-7 1/° С; wetting angle ~ 15 deg.

To obtain stable antenna output characteristics, that is, to maintain a stable parametric phase value, materials with a fixed dielectric constant value, low dielectric losses and a high absolute TKE value that contributes to the displacement of parasitic resonances, and ultimately - to remove them from the operating frequency zones, are required. The necessary materials were synthesized by the design bureau in the system MgO - SzO - TiO2 and received the name - ceramics of the brands MTS-30, MTS-25.

These materials are used in modern designs of phase shifters of multi-element phased antenna arrays (headlamp) installed on domestic MIg fighters.

CSC RM is the developer of a unique range of radio absorbing materials (RPM) and electromagnetic wave absorbers (EW), which have found wide use in equipping echo-free chambers and shielded test rooms, including to ensure product tests for compliance with EMC standards and requirements and biological protection of maintenance personnel from the harmful effects of electromagnetic radiation.

Existing conventional adhesive materials do not find proper use due to the inconsistency of their characteristics with modern requirements. The Central Design Bureau of the Republic of Moldova has created new functional adhesive compositions that provide a strong connection of various materials (glass, ceramics, metals, etc.), non-soldering, "cold" installation of units and blocks, their shielding and repair. Thus, composite heat-resistant electrically conductive adhesive compositions are used when replacing failed suspended elements in the field, excluding traditional soldering. The creation of electroconductive adhesives (rv = 10-5 Ohm m in the temperature range -60... + 200 ° C) became possible only during the development of the Central Design Bureau of PM fine metal powders with stable properties.

The development of a parametric series of optical adhesives with a refractive index of 1.401 to 1.6 made it possible to manufacture optoelectronic blocks and units, and the glue carries an additional functional load, being a reflective shell at the quartz-polymer boundary in quartz-polymer light guides.

Elastic, heat-resistant, fast-curing one- and two-component adhesives simplify the installation and guarantee the fail-safe operation of microelectronic units over a wide temperature range.

Practical value of elastic sealing compositions lies in their manufacturability combined with high physical and chemical operating parameters. Products based on them work successfully under conditions of multiple cyclic temperature changes.

On the basis of siloxane and polyester resins, pouring compounds are created, resistant to mold fungi, corrosion-inert to metals. As part of the nodes and blocks, they were successfully tested in subtropical and tropic (Cuba) conditions.

Another activity of the CSC RM is the development of anti-icing coatings due to the use of new organosilicate compositions with high hydrophobic properties, which ensures the operability of products in the North. At the same time, the company is doing a lot of work to replace scarce raw materials or components, the production of which has been discontinued or remained in the CIS countries, with less scarce ones, while maintaining all the properties inherent in materials synthesized on their basis.

For the first time in domestic practice, the Central Design Bureau of the Republic of Moldova has developed a highly efficient electronic and chemical technology for producing composite materials, which differs from traditional ones in high performance (cure rate of at least 1 sq. m per minute), low power consumption (20 times lower than during thermochemical curing), as well as a decrease in raw material consumption, excluding environmental pollution, explosion and fire hazard of production. Materials obtained by this method are significantly cheaper (1.5-2 times) compared to those obtained by traditional technologies (direct printing, coating with natural veneer, plastic, etc.).

Based on the developed electronic and chemical technologies, industrial production was created:

• roll foil fiberglass and based on them new large-format diagram-forming schemes (up to 11 m long) for special equipment;
• polymer tubes (diameter from 0.5 to 60 mm) with shape memory effect for cable bundles sealing with simultaneous mechanical hardening and insulation of connection points;
• finishing non-combustible slab materials for finishing public and industrial buildings.

The technology was developed and technical documentation was created for special technological equipment used in the production of polymer composite film with a memory effect for the insulation of large-diameter pipelines.

Participation in exhibitions and conference organizations

In order to promote the developed materials, the Central Design Bureau of the Republic of Moldova takes an active part in the preparation and holding of industry, inter-industry and international exhibitions, conferences and meetings of the material science profile.

About 100 developments of the enterprise were presented at international exhibitions and fairs in Singapore, Bologna, London, Seoul, Delhi, Vienna, Budapest, Sydney, Milan, Johannesburg, Brussels, Hanover and other cities of the world.

For the successes achieved, the Central Design Bureau of Special Radio Materials received more than 20 honorary diplomas and certificates of organizing committees, and employees of the enterprise were awarded 84 medals of the exhibitions "Progress-83," "Progress-86," "Progress-87," "Setun-89," "SOI-91," "First International Aerospace Salon in Russia," "Fifth Anniversary Exhibition Salon" Mechanical Engineering, "" Conversion Market, "" Science and Technology - to the city "in honor of the 850 anniversary of Moscow" 98.

More than 30 scientific and technical conferences and seminars were held, at which employees made about 240 reports on the subject of the enterprise. The most interesting topics of seminars and conferences were:

• "The state and development of special radio materials in the USSR and abroad";
• "Radiation and chemical processes in the production of materials and products of radioelectronic equipment";

Catalogs have been published for products of the Central Design Bureau of the Republic of Moldova, as well as scientific and technical collections of materials recommended for implementation at enterprises of the radio industry and related industries. Based on the results of research and experimental work, 190 copyright certificates and patents were obtained.

TsKB RM has close scientific and production relations with the institutes of the Academy of Sciences of the Russian Federation, universities, organizations and enterprises of radio electronics, aerospace, chemical, metallurgical, electrical industry and others. industries, which to a large extent contributes to both the organization of production and the introduction of materials developed by the team of the Central Design Bureau of the Republic of Moldova.

1985: The creation of a new nomenclature of RPM and PEV has been completed

By 1985, the creation of a new nomenclature of RPM and PEV was practically completed, regulatory, technical and reference documentation for their use was developed and issued. We have prepared production facilities with the use of modern echo-free chambers that fully meet the need of enterprises of various industries to replace combustible RPMs in operation.

The main advantages of the new RPM and PEV should primarily include:

• high radio technical and operational parameters, which are maintained at long service life both indoors and outdoors;
• use of domestic technologies and raw materials used in the production of construction, heat and sound insulation materials;
• multifunctionality of developed materials;
• fire safety and environmental cleanliness of materials ensuring sanitary and hygienic standards and requirements;
• absence of foreign analogues.

The most widely used are the following RPM and PEV:

• on the basis of a special micro-pipeline (RPM "Vors");
• based on cellular concrete with fibrous carbon filler (PEV "Aerated Concrete," "Granite," "Wall");
• on the basis of foam glass with powdered carbon filler (PEV "Quartz," "Garnet," "Micron," "Temp");
• on the basis of expanded granules made of liquid glass with a conductive coating (PEV "Universal");
• based on foam ceramic with (powdered) carbon filler (PEV "Crystal").

Taking into account the absence of ultra-wide-range electromagnetic wave absorbers in the country that meet the requirements of international standards and are necessary for equipping shielded chambers in which products should be tested for compliance with EMC standards and requirements, the RM Central Design Bureau carried out a number of works to create the most promising ultra-wide-range PEV designs (0.03-10.0 GHz): PEV "Temp" and "Range-265," which have no foreign analogues in their design solution, as well as the ferritodielectric PEV "Pokrov-31" and its modifications, which correspond to the best foreign analogues of the USA and Japan.

Printed installation is the basis for the production of electronic products, in connection with which up to 1.5 thousand tons of foil dielectrics were processed in the industry until 1985. Waste disposal costs began to approach the cost of the main production.

An original technical solution was found in the Central Design Bureau of the Republic of Moldova, which made it possible to apply a layer of metal to the insulating base instead of selective etching of copper foil, that is, an additive process was implemented for the manufacture of printed circuit boards using composite materials with a catalyzed filler that provides a selective chemical metallization process.

The work in this direction made it possible to reduce the consumption of expensive copper foil, reduce energy and labor costs. Materials such as catalyzed glass-textolite CSF, polyalkanimide brands AI-IT, AI-ITM and catalyzed polyaminobismaleimide brands PAIS-K, as well as enamel EP-5215 with a positive result were tested at a number of enterprises of the electronic, radio and aviation industry and entered into industry standards. All original solutions are protected by copyright certificates and patents. In 1988, we announced our work at the anniversary session of the European Printed Circuit Board Institute in Zurich, Switzerland. The materials of the report were published in the journal of this institute.

1976: Conversion to Central Design Bureau

In 1976, the Radio Safety Bureau was transformed into the Central Design Bureau of Special Radio Materials, the priority area of ​ ​ which is the development of special-purpose radio materials: HF and microwave ceramic materials, radio-absorbing and shielding materials, optical, current-conducting and heat-conducting adhesives and sealants, materials for additive and semi-additive technology for the manufacture of printed circuit boards, materials of radiation technology, heat-resistant and heat-resistant casting and impregnating compounds.

In pursuance of the decisions of the Government of the Central Design Bureau of the Republic of Moldova as a leading enterprise in the period 1977-1985. organized and ensured a whole range of work related to the development and industrial development of new highly efficient and fire-safe radio-absorbing materials and products in the interests of defense industries.

1969: Formation of a special design bureau

CKB RM was formed in 1969 as a special design bureau of radio materials at NICEVT. In the first years of its activity, SKB was engaged in organizing development, creating new capacities for the production of special radio materials and chemical reagents in conjunction with related industries such as chemistry, petrochemistry, electrical engineering, electronics, etc., which significantly reduced the development and implementation time, reduced economic costs for their implementation and at the same time stimulated the development of these industries.
