Ailerons are the moveable control surfaces attached to the outboard trailing edge of each fixed-wing aircraft. They are connected by pulleys, cables, bellcranks, and pushpull tubes to a control wheel or control stick. Ailerons are usually placed in pairs and move in opposite directions during operation. These are one of the primary control surfaces of aircraft, which turn or fine tune aircraft's altitude and provide rolling movement about the longitudinal axis.In this report, Technavio covers the present scenario (with the base year being 2016) and the growth prospects of the global ailerons market for commercial aircraft market for 2017-2021. The average cost of ailerons for each aircraft type (wide body, narrow body, and regional jet) has been taken into consideration for estimating the market revenue.

An aerostat, including unpowered balloon (free-flying or tethered) and powered airship, is lighter than an aircraft; aerostat gains its lift by using buoyant gas.The regional tensions in the Middle East (especially in Iran, Iraq, Israel, Lebanon,and Turkey) and Eastern European countries (Belarus, Bulgaria, and Ukraine) are driving the demand for aerostat systems for surveillance.Due to the growing maritime security concerns and sea-border threats, the aerostat systems market is expected to grow rapidly in APAC, posting a CAGR of 12.15% during the forecast period.Globally, the increasing use of aerostat systems depicts their viability for costeffective surveillance, data transmission, and communication even during harsh climatic conditions and rough terrain.

In this report, Technavio covers the present scenario (considering the base year to be 2016) and the growth prospects of the global aerospace nanotechnology market for 2017-2021. To calculate the market size, the report considers the revenue generated in the overall market from the procurement of commercial and military aircraft components and subsystems (airframe structures, aero-engine parts, and aircraftelectro communication systems) that are manufactured using nanotechnology. Also,the report covers the revenue generated by the use of nanotechnology in spacecraft/satellite. However, both funded and unfunded R&D investments in the development of prototypes and components were not considered for the derivation of the market size for the base and projected years.

Aerospace fasteners have evolved over the years with the constantly changing aerospace industry. These components are widely used in commercial and military aircraft, ballistic missiles, rockets, and associated aftermarket services. The aerospace industry employs a wide range of fasteners such as bolts, nuts, screws, rivets, and pins.Technavio expects the global aerospace fasteners market to grow at a CAGR of 6.86% during the forecast period. In 2015, the Americas led the global market with a share of 44.04%, followed by EMEA with a share of 30.17%, and APAC with a share of 25.79%.Over the forecast period, the countries in APAC are expected to be the fastest growing

market for aerospace fasteners owing to the significant contributions from Australia,India, Japan, China, Malaysia, Singapore, and South Korea.In this report, Technavio covers the present scenario (with the base year being 2016) and the growth prospects of the global aerospace fasteners market for 2017-2021.

In this report, Technavio covers the present scenario (with the base year being 2016) and the growth prospects of the global aerobridge market 2017-2021.The report considers aerobridges that are being newly installed and those that are undergoing maintenance, repair, and overhaul services, including refurbishment and retrofitting. Market sizing is done taking into account the money spent by each of the

three regions (Americas; Europe, Middle East, and Africa [EMEA], and Asia-Pacific [APAC]) into manufacturing and acquiring these aerobridges/passenger boarding bridges (PBBs).The report presents the market segmentation based on type (apron drive, commuters,

dual systems, nose-loaders, and others) and geography (Americas, EMEA, and APAC).In addition, it discusses the major drivers that influence the growth of the global aerobridge market and the impact of these drivers on key customers, which include airport authorities. Further, it also discusses the challenges faced by vendors and the market at large, as well as the key trends that are emerging in the market.

Light electric aircraft are emerging as new frontiers in the aerospace industry with improvements in technology. New investments in lighter components, high energydense batteries, and more efficient power electronics are driving the light electric aircraft market. Also, funding from governments and other advantages like tax benefits are encouraging increased number of vendors to enter this market. High taxes on greenhouse gas emissions and stringent noise regulations are also forcing aircraft manufacturers to focus on electric aircraft.

进入 5 月份以来，我国周边国际局势发生了新变化。虽然有美军轰炸机飞越南海、反导试验取得成功等事件影响，但传统上与中国关系较为紧张的国家和地区，包括日本、印度、韩国、东盟诸国等，正通过各种渠道缓和双方关系，合作协商的态势已然形成。我们认为，我国周边国际局势正进入缓和期，美军进行反导试验、轰炸机飞跃南海等个案不会改变整体外部环境趋向缓和的大趋势。 

回顾 2016 年军工行业业绩，军工行业上市公司业绩保持整体稳定状态，2017 年一季度部分上市公司业绩有所改善，但军工年底交货特点，一季度业绩释放空间有限。今年军工行业处在混改等改革和军机批产等中长期拐点利好兑现期，行业正全面向好。二季度在市场风险偏好变化等情况下，市场忽视军工行业基本面向好的变化，军工板块上市公司股价大幅回撤，板块整体被错杀，投资价值被低估。 

行业维持高景气度，预计未来3年行业净利润年均增速将维持20%左右；军工指数大幅回调，回到2014年11月的水平，即牛市启动初期的水平；我们研判军工板块：2017年下半年将以震荡态势为主。

In this report, Technavio covers the present scenario (with the base year being 2016) and the growth prospects of the global unmanned aerial vehicle (UAV) payload and subsystems market for 2017-2021. To calculate the market size, the report considers the revenue generated in the overall defense market from the procurement of sensors and cameras, weaponry, radars and communication systems, and other types of UAV payload and subsystems (ground control stations [GCS] and onboard computers).However, both funded and unfunded R&D investments in the development of UAV prototypes and payload components were not considered when deriving the market size for the base and projected years.
