Mapping the structure and dynamics of global high‐tech aerospace trade

AbstractThe aerospace industry is a fast‐growing high‐tech sector related to the national economic lifeline and national defence security. In the context of prosperous cooperation and fierce competition between countries, a multi‐layered global aerospace network, from production to trade, has been formed. However, the high‐tech aerospace trade structure and its spatial pattern as the mirror of the industry lack systematic research. This study constructs global high‐tech aerospace trade networks to review the trade dynamics, identify the core countries and explore the regional structure and geographical characteristics. Different high‐tech aerospace segments show varying evolutionary characteristics, with exports more concentrated than imports. The United States and Western Europe dominate the import and export market in all categories of high‐tech aerospace trade, especially in high‐end segment, holding organizational authority in the community structure. Although Asia is rising rapidly in some areas, it still has a long way to go to become a global hub.

Failure criterion for PA 12 multi-jet fusion additive manufactured parts

Abstract Offering the possibility of producing complex geometries in a compressed product development cycle, it comes as no surprise that additive manufacturing (AM) techniques have become attractive to multiple industries, including the automotive and aerospace segments. Unfortunately, the ubiquitous stratified build approach used by these technologies is responsible for the pain point that hinders their adoption in production of parts that will be subjected to complex loads: the junction of adjacent layers tends to have subpar mechanical properties when compared to those of the bulk material, and thus, assessing the structural integrity of an AM part becomes difficult. In the advent of the industrialization of series production of AM parts for the automotive industry, the necessity to understand and predict how and why AM parts fail under complex stress states becomes of paramount importance. This paper applies a failure criterion for materials with anisotropic properties with stress interactions, to predict failure of multi-jet fusion (MJF) parts manufactured using polyamide 12 powder. The results are compared to the failure surfaces of Selective Laser Sintering (SLS) components. Special test specimens were designed, produced, and tested to measure failure under tensile, compressive, shear, and combined loading scenarios. The results show that much like SLS, MJF parts have a notable difference in tensile and compressive strengths. Unlike SLS however, MJF parts do not exhibit a strong interaction between stresses when under combined loading. The experimental data shows an excellent fit with the failure criterion, precisely capturing the strength behavior of MJF printed parts under complex loading conditions. Of great interest in this study is that the stress interactions with MJF parts were determined to be negligible when compared to SLS specimens, which emphasizes the fact that when performing stress analyses, each one of these powder-based additive manufacturing techniques must be treated differently.

Оценка эффективности импортозамещения в авиационно-космическом сегменте военно-промышленного комплекса с учетом минимизации рисков

В 2014 году странами НАТО были введены ограничения на поставку импортного оборудования и комплектующих в Российскую Федерацию. В связи с чем была актуализирована проблема национальной безопасности, решение которой требует разработки и применения целого комплекса мер - экономических, организационных и правовых. Государство впервые за много лет столкнулось с реальной необходимостью импортозамещения. Вопросы импортозамещения являются стратегически важными, от их решения зависит обеспечение обороноспособности национальной экономики. Государство перешло к стратегии импортозамещения и поддержке отечественного производителя. In 2014, Russian Federation was restricted in importing of foreign equipment and component parts by countries that were NATO members. In that situation, the importance of national security issues increased. To deal with those issues, a range of different measures such as economical, organizational and legal were to be applied. After a long time, once again Russian Federation faced the problems concerning import substitution. National security issues are strategically important, solving these issues effects national economics defense potential. Russian Federation followed the import substitution strategy and started to support domestic producers.

Studies on mechanical properties of aluminum based hybrid metal matrix composites

Aluminum alloy provides the best alternative to steel with improved performance over the more common metals and alloys frequently used in automotive industries and aerospace segment. Hybrid Aluminum Alloys Metal Matrix Composites (HMMCs) are gaining specific attentions in automotive and aerospace applications based on its low density, high strength and its good structural rigidity. In this research work, an investigation is made to fabricate and compare the mechanical and metallurgical properties of Al 6063-Silicon Carbide with Al 6063-Silicon Carbide/Graphite hybrid metal matrix composite materials. The composites were manufactured by means of stir casting techniques in which quantity of reinforcement is in the range from 5% to 15% in steps of 5 wt.% per sample. The manufactured composites are characterized by mechanical properties, density and microstructural studies and evaluated as per ASTM standards. The optical microphotographs of the composites are uniform distribution of the hybrid particles in the composites with few clusters. The experimental densities were found to be lower than, compare to the theoretical densities in all the composites. The dispersed Silicon Carbide and Graphite in Al 6063 alloy contributed to improving the tensile strength (MPa) of the composites. From scanning electron microscope (SEM) analysis, the samples were found having uniform distribution of the hybrid reinforcement particles (SiC.and Graphite) in the matrix without any tunnel and voids effects.

Failure surface development for ABS fused filament fabrication parts

Fused Filament Fabrication (FFF) is the most widely available Additive Manufacturing technology. Offering the possibility of producing complex geometries in a compressed product development cycle and in a plethora of materials, it comes as no surprise that FFF is attractive to multiple industries, including the automotive and aerospace segments. However, the high anisotropy of parts developed through this technique implies that failure prediction is extremely difficult -a requirement that must be satisfied to guarantee the safety of the final user. This work applies a criterion that incorporates stress interactions to define a 3D failure envelope that could prove an invaluable tool in formalizing the embrace of FFF in industry. Tensile, compressive and torsion tests were executed on coupons developed in a traditional FFF printer, as well as a customized, 6-axis robotic printer necessary to produce specimens in out of ordinary orientations. These tests were used to calculate the parameters of the mathematical function that describe the failure envelope. Mechanical tests clearly showed significant difference between tensile, compressive and shear strengths. The calculated envelope shows strong interactions between axial loads, and a considerable interaction between shear stresses and loads applied in directions parallel and perpendicular to the beads.

The Role of High-Altitude Platforms (HAPs) in the Global Wireless Connectivity

Since 1990s, the investigations of aerospace communication segment have not only been concerned with satellites, but increasingly with lower altitude repeaters flying in the stratosphere. They are the so-called high-altitude platforms (HAPs) with important advantages with respect to satellites in terms of reduced cost of implementation, deployment, and launch. However, HAPs are characterized by a reduced coverage, as compared with satellites. Nevertheless, in recent literature, HAPs are not regarded as competitors of the satellite technology. On the contrary, the emphasis is on the effective and seamless integration among heterogeneous aerospace segments (GEO, LEO, and HAP) and aerospace segments with terrestrial wireless networks in order to globally extend the broadband wireless connectivity. This paper is focused on the role of HAPs in providing global connectivity in future communication systems and services. Potentialities, enabling technologies, and challenges are presented from the perspective of the integrated terrestrial/HAPs/satellite communications infrastructure.

Sand Slurry Erosive Wear Behavior of Hot Extruded Al6061-SiC Composites

Aluminum based composites are very popular in automotive and aerospace segments. In particular aluminum alloy-SiC composite systems are widely studied and seriously explored for various other applications in defense and space. However they have not been looked at as potential materials in naval and chemical applications where synergistic effects of both wear and corrosion need to be addressed to. This needs the assessment of wear behavior of composites. From the survey, it is evident that major focus is on mechanical and corrosion properties of cast composites. However, meager information is available as regards the slurry erosive wear behavior of cast and extruded metal matrix composites.

Characterization of titanium welded joints by the orbital gas tungsten arc welding process for aerospace application

In this work, three welding programs for orbital gas tungsten arc welding (GTAW), previously developed, were used, using pulsed current and increasing speed (#A), constant current (#B) and pulsed current and decreasing current (#C). One of these should be used for the propulsion system of the Satellite CBERS (China - Brazil Earth Resources Satellite). Welded joints using tubes of commercially pure titanium were obtained with these procedures, which were characterized by means of mechanical and metallographic tests. The obtained results showed that the three welding procedures produce welded joints free of defects and with adequate shape. Although small differences on mechanical properties and on microstructure have been observed, the three welding programs attained compatible results with international standards used in the aerospace segment. The welding program #B, due to the reduced heat input used, was considered to obtain slightly advantage over the others.
