MRO plays an important role in extending the life of an aircraft by increasing the operational efficiency. It includes services such as overhaul, routine check-up, inspection, repair, and modification of aircraft and their components. These services assure the safety and airworthiness of aircraft. MRO services are conducted on engines, airframe, and components and involve careful examination to detect damages or corrosions caused inside the skin of the aircraft, engine valves, and all the parts where an extensive check is required.

EMEA and the Americas dominate the global computational fluid dynamics (CFD) markset in the aerospace and defense industry. The presence of aerospace and defense companies in the US and Germany is the major factor driving the market.The increased need for CFD in the R&D of aerospace and defense industry is driving the market. The National Aeronautics and Space Administration (NASA) plays a major role in the growth of the CFD market in the aerospace and defense industry.Growing military expenditure due to increased security threats and the growth of cloud CFD are some of the major driving factors in the market.The market faces several challenges such as inaccuracy of CFD calculations in certain scenarios such as turbulent flow analysis.The growth of small and medium enterprises (SMEs) in the aerospace and defense industries such as SpaceX is a major trend in the market, which is expected to create a positive growth in the market.

The global computer-aided design (CAD) market in the aerospace and defense industry is highly driven by the increase in defense spending in 2015 and 2016 by countries such as the US, France, and China. For instance, France is expected to increase its defense spending by $660 million by 2017. This is expected to drive the R&D in this industry, which will increase the demand for CAD software.The demand for CAD software is expected to be high due to increasing demand for passenger aircraft worldwide. The number of flight passengers will increase globally during the forecast period; hence, many airline companies will require more passenger aircraft. As CAD is used for expediting the whole manufacturing process of aircraft, the demand for the software will be high.The implementation of CAD software and its training are expensive. This acts as a major drawback, especially in the APAC market where major end-users are small and medium-sized enterprises (SMEs), which have budget constraints.

Lighter airframe construction, reliable avionics, efficient power supply, and greater modularity are expected to reduce the cost of business jets.The impact of 3D metal printing is expected to be significant over the forecast period. It will likely be one of the most crucial steps toward discovering new possibilities for design and manufacturing of business jet parts and its associated components.In recent years, the business jet industry has witnessed an increase in the market dynamics. It is expected to continue in the future, as weaker players that are unable to provide technological and service innovations leave the business,bolstering the presence of large companies.In this report, Technavio covers the present scenario and growth prospects of the global business jet market for 2016-2020 (considering 2015 as the base year). The market size has been calculated from the revenue generated by the sales of business jet aircraft. The average price of light business jet, mid-size business jet, and large business jet has been taken into consideration for estimating the market revenue.

The growing regional frictions and extremist attack tensions in Asia (especially in the South China Sea and the Atlantic Ocean) are driving the need for aircraft carriers.The accelerated use of nuclear energy to power aircraft carriers is a major driver of the market. The use of nuclear energy is cheaper compared with diesel and will result in increased power and reduced greenhouse missions.The introduction of Electromagnetic Aircraft Launch System (EMALS) is an emerging trend in the market because it is light; energy efficient; requires lesser space, low maintenance, and workforce; and effectively enables aircraft launch.The Gerald R. Ford aircraft carrier, developed by Huntington Ingalls Industries, is a major product in the market that will replace some of the Nimitz-class ships of the US Navy.

Owing to the innovative additive manufacturing approaches taken by both the original equipment manufacturers (OEMs) and component suppliers, the overall manufacturing cost for aircraft components is anticipated to decrease. This is expected to propel the adoption rates of three-dimensional (3D) printing technology in the production of commercial aircraft parts.The growing adoption of lightweight and fuel-efficient aircraft will also influence the acceptance of 3D printing technology globally. Owing to the substantial investments, the Americas will have the highest market share of 43.56% in 2020,followed by APAC with 31.24%.The increasing efforts to develop miniaturized jet engines will drive the adoption of 3D printing technologies among engine and component manufacturers across the globe. Also, it is expected that there will be increased collaborations among OEMs and computer-aided design (CAD) technology providers, which will ensure further advancements in the existing 3D printing technology.

Bikes and ride-on products are helpful for children, as they help strengthen their leg muscles, improve co-ordination, and encourage babies and children to be active. The improved standard of living, along with a rise in disposable income among the middle class population, is propelling the demand for bikes and ride-ons for babies and children in the emerging economies in APAC like China, India, and Malaysia. The per capita disposable income in China increased to $4,756 in 2015 from $4,397 in 2014. The global bikes and ride-ons market for babies and children is expected to post a CAGR of 8.23% over the forecast period.

Rolling stocks are wheeled vehicles that move on railway tracks. Rolling stocks include passenger trains, locomotives, and freight wagons. These vehicles can be non-selfpropelled or self-propelled. Rolling stocks are capital-intensive and require huge investment and time to manufacture. Alstom, Bombardier Transportation, CRRC Corporation, GE Transportation, Mitsubishi Electric, and Siemens are the major rolling stock manufacturers in the market.

A significant part of the demand in the global welding safety market will arise from the construction and manufacturing sectors, which jointly accounted for nearly 50% of the overall market in 2015.The demand for welding will increase over the forecast period, especially from the manufacturing industries in developing countries. As welding is extensively used in the manufacturing industries, the rising demand for welding will, in turn, increase the demand for welding safety.Welding is one of the major processes in the construction industry. The global construction output is expected to grow by 85% to reach $15 trillion by the end of 2030. The global construction industry will grow at an annual rate of 4% until 2030,which is higher than the projected global GDP growth rate of 3% per annum.The implementation of robotic welding technology and automated welding technology will significantly limit the market growth as the demand for manual welding will decline. Automated welding solutions offered by companies like Lincoln Electric and Gullco International help end-users execute welding with the highest efficiency. Increased output, improved quality, and reduced overall cost propel endusers to adopt robotic welding. This will decrease the demand for welders, in turn,decreasing the demand for welding safety equipment in the market.
