Abstract:

With the advent of the Fourth Industrial Revolution, the Korean industrial environment has been rapidly changing. As a result, several industries are facing different innovation conditions, including: the automotive industry, which is a traditional manufacturing industry in Korea; the aerospace industry, which has been vertically integrated, and has been led by a single large company—Korea Aerospace Industries—since Korea went through an economic crisis in the 1990s; and the robotics industry, which is currently emerging. This study used parameters related to patents originating from the automobile, robotics, and aerospace fields. The patents subjected to analysis were those registered in Korea from 2001 to 2014, and included those that were applied for, jointly applied for, or registered by Korean companies. This study analyzed the differences caused by the effect of open innovation in the three industries. According to our results, first, the three industries experienced different effects of open innovation. Second, when large companies controlled a given industry, open innovation either worked a little or did not work at all. According to this research result, the Korean robotics industry, which has a weak dominance of large companies, experienced a strong effect of open innovation, in that joint patent applications led to economic gains from the patents and an increase in technology transfer and technology value. The aerospace industry of Korea, which has the highest dominance of large companies, experienced a slight effect of open innovation, as the effect of joint patent application only improved the technology value. Finally, the automotive industry of Korea had an intermediate level of open innovation, between the aerospace and robotics sectors.

Abstract:

The article raises the issue of the relevance of the development of international cooperation in the aerospace industry, taking into account the trends of post-industrial society, the development of artificial intelligence, and the transformation of the world society. It is specified that one of the key indicators of the transition from an industrial to a post-industrial society is the active development of the service sector and the importance of education and the knowledge economy, which come to the fore. The economy of post-industrial societies is dominated by innovative sectors such as high-performance industries, high-quality and innovative services as a share of GDP, and a larger share of the population employed in the service sector than in industrial production. A country with a highly developed aerospace industry demonstrates its national strength, scientific and technological innovation, effective public policy, strategic vision and principles of national security. At the international level, the leading countries of the world have identified the coordination of space activities and the development of aerospace industry as a priority of the national level. Ukraine has a complete space complex (rockets, spacecraft, ground control centers, data processing centers) and most aviation platforms (reusable spacecraft, some passenger aircraft, military transport, transport-only), has the potential for construction, research and development, can organize the production, operation and use of the rocket, space and aviation technology. The aviation industry and the space industry outline the long-term prospects for the development of the country’s economy. In terms of development, the aerospace industry is ahead of other industries and plays a vital role in modern civilization. The development of the aviation industry is urgent for Ukraine, including the development of ground airport infrastructure, air transport and a combination of ground and air transport.

Abstract:

AbstractAdvances in the nanotechnology have been actively applied to the field of aerospace engineering where there is a constant necessity of high durable material with low density and better thermo-mechanical properties. Over the past decade, carbon nanotubes-based composites are widely utilised owing to its fascinating properties resulting in series of multidisciplinary industrial applications. Carbon nanotubes (CNTs) are rolled up sheets of carbon in nanoscale which offers excellent thermal and mechanical properties at lower density which makes them suitable reinforcement for composites in aerospace applications. Owing to its high Young’s modulus and chemically inert behaviour, CNTs are forefront of material research with applications varying from water purification to aerospace applications where applicational sector remains a mystery. Although there has been numerous research on the CNTs-based materials, there are only limited studies focusing on its utilisation for the field of aerospace engineering. As a result, in this review, we intend to cover the processing and synthesis techniques, thermal and mechanical properties as well as few industrial applications of CNTs-reinforced ceramic composites. Further, any potential development in additive manufacturing-based technique for fabricating CNT/ceramics and its applications in aerospace industries have been highlighted.

Abstract:

As many manufacturing industries have declined and as much American manufacturing has become vulnerable to foreign competition, numerous groups have suggested that programs to intervene in specific manufacturing sectors could help. Proponents focus on aid to telecommunications, aerospace, information technology, and high-definition television, where an edge in new technology may be key to the industries' success, but they also touch on aid to declining industries. Opponents of trade restrictions often argue that policies should facilitate adjustment in industries injured by trade. Other groups call for a technological “revolution” in manufacturing to restore international competitiveness through programs to facilitate adjustment and to speed the transition to new kinds of manufacturing. Others, concerned about massive job losses in depressed manufacturing communities, have called for improving the welfare of workers and communities.

Abstract:

Because of its high hot strength and corrosion resistance, Inconel 825 superalloy has various industrial uses in the aerospace, nuclear, automotive, and defense industries. However, characteristics like as work hardening, poor heat conductivity, and chemical reactivity with tool material make it "difficult-to-machine." Its machining via the traditional approach is difficult for industries. The machining behavior of Inconel 825 under distilled water-based minimum quantity lubrication (MQL) is examined in this work using a PVD- TiN/TiCN/TiN coated cermet insert. The tool's tip temperature, cutting force, and flank wear are all investigated. Keywords: Inconel; corrosion resistance; MQL; cermet.

Abstract:

General structures or machines are firmly connected by bolts so that they have many contact surfaces. Between these contact surfaces, there is a movement that vibrates with tiny amplitude, which causes friction, leading to fretting damage. This damage causes a remarkable reduction in the fatigue strength of the structures sub-materials, leading to remarkable fall-down of life span of machines and structures. The particle reinforced composites under research in the aerospace and automobile industries, theoretical analysis and research on fretting fatigue involved with contact are needed, but there are few domestic studies. Therefore, this study is to identify cracking damage, its initiation, growth direction and location by considering the strength load and contact (surface/surface) in particle reinforced composites. So it performed a study on ellipsoidal particle reinforced composites that have contact force under tensile load. This study performed a theoretical analysis and a fretting test to identify damage mechanism to industrial structures as well as aerospace and automobile industries according to expanded coverage of application and development of the composites.

Abstract:

Friction Stir Welding (FSW) is a solid state joining process which possesses a great potential to revolutionise the aerospace industries. Distinctive materials are selected as aerospace alloys to withstand higher temperature and loads. Sometimes these alloys are difficult to join by a conventional welding process but they are easily welded by FSW process. The FSW process in aerospace applications can be used for: aviation for fuel tanks, repair of faulty welds, cryogenic fuel tanks for space vehicles. Eclipse Aviation, for example, has reported dramatic production cost reductions with FSW when compared to other joining technologies. This paper will discuss about the mechanical and microstructure properties of various aerospace alloys which are joined by FSW process.

Abstract:

This paper explores the feasibility of implementing 3D printing technology for manufacturing seat buckles in the Airbus A380. While additive manufacturing has gained attention for its versatility, safety-critical components require rigorous testing and certification. Through a comprehensive review of literature and expert interviews, this study analyzes the viability of 3D printing for seat buckle production. The results indicate that traditional manufacturing methods, such as injection molding and forging, remain the preferred choices due to their established reliability and quality control procedures. The aviation industry places the utmost importance on safety and reliability, especially in the manufacturing of safety-critical components like seat buckles. This paper examines the potential integration of 3D printing technology into the production process of seat buckles for the Airbus A380, considering the stringent certification requirements and performance expectations. A literature review encompassing additive manufacturing techniques, aerospace certification processes, and current seat buckle manufacturing practices was conducted. Expert interviews were also conducted to gather insights from industry professionals with expertise in aerospace manufacturing. The analysis revealed that conventional manufacturing methods such as injection molding and forging are currently preferred for seat buckle production in the Airbus A380 and other aircraft parts. These methods have established reliability and quality control procedures, ensuring compliance with rigorous safety standards. Although 3D printing has found success in prototyping and non-critical components, its application in safety-critical components like seat buckles is limited. The decision to favor traditional manufacturing methods for seat buckle production in the Airbus A380 is driven by the need for extensively tested and certified components. Safety-critical parts undergo stringent testing to guarantee their performance under various operating conditions. While 3D printing offers design flexibility and reduced lead times, further research and development is necessary to ensure its viability in safety-critical applications. At present, 3D printing technology is not widely employed for manufacturing seat buckles in the Airbus A380. Traditional methods provide the required reliability and quality control procedures. However, ongoing advancements in additive manufacturing may present future opportunities for incorporating 3D printing technology into safety-critical applications within the aerospace industry. Further research and development are necessary to explore these possibilities.

Abstract:

Pollution prevention is a concern to numerous industries. Aerospace manufacturers have a new challenge in the technical arena known as life cycle environmental engineering. The Department of Defense (DoD) now incorporates these requirements into its acquisition policies and directives. The focus is to minimize or eliminate the use of hazardous materials throughout the life cycle of future DoD products. This new and emerging technology necessitates that another element be added to the design, manufacturing, testing, and maintenance of DoD products. Aerospace industries must incorporate this task into their business objectives if they are to compete in today's defense marketplace. This paper answers questions concerning DoD directives and explains how companies can develop an approach to meeting these environmental life cycle requirements.

Abstract:

Fiber reinforced polymer (FRP) composites possess excellent specific strength, specific stiffness and controlled anisotropy for which these are extensively used in various engineering applications, like automobile industries, aerospace industries, marine industries, space industries, electronics industries and many more. Glass fibers (GF), carbon fibers (CF) and aramid fibers (AF) are common reinforcements for polymer matrix composites (PMCs). High mechanical properties and wear resistance behaviour of glass fiber reinforced composites are the premises for the current experimental research on the effect of fiber orientation on the tensile strength of the polymeric composite materials. The glass fiber reinforced epoxy resin composite was prepared by wet lay-up method, followed by thermal treatment.
