Unlike conventional chemical propulsion satellite, electric propulsion satellite employs electrical energy streams to change the velocity of spacecraft.To estimate the overall market for the base year, Technavio has considered the revenue generated from the procurement of hybrid propulsion satellite (the ones which used both chemical and electric propulsion technology) and all-electric satellites. Both funded and unfunded R&D investments are not considered to accumulate the overall market size or for projection of the forecasted years.

新型号跻身世界一流水平并进入批产期，航空高增长拐点显现 从中美军用飞机数量来看，除了战斗机为美国 1/2 多，其余机型差距均较 大；从型谱和技术指标来看，中国军用飞机主流型号已经基本与美国一致， 在战斗机与运输机方面较接近，隐形轰炸机还有不足，直升机型谱有差距， 随着直 20 逐步成熟，通用型直升机的不足将得到补充。我们认为，军用飞 机未来在陆海空和战略支援部队等几大军种中的需求增长都较确定，将充 分受益军队改革和军工改革。2017 年运 20、歼 20、J15、L15 等机型将 进入爬坡上量的阶段，军机产业链正处在这波持续高增长的拐点投资阶段。

An offshore supply vessel is a sea motor vessel used for transporting cargos, goods, supplies, crews, and offshore exploration and production (E&P) across oil platforms. OSVs support marine offshore drilling activities through transportation of offshore energy resources, and they also facilitate the installation process of oil rigs. They are mostly used by oil and gas companies for E&P activities. The OSVs are operated by ship owners or by companies that take OSVs on lease. In addition, the OSVs facilitate maritime logistics operations for different industries such as subsea and deepwater mining.

全球铁路市场容量目前是 1675 亿欧元，未来以每年 3.4%的速度增长，到 2018 年有可能增长到 1900 亿欧元。目前，南美、中东欧、俄语地区的铁路运输设备已经进入了车辆更新换代的高峰，潜力巨大;非洲地区对机车、货车、普通客车的需求也在逐步增加。同时很多国家已经将高铁作为交通运输领域的发展重点，未来高铁有望成为全球铁路市场重要的增长点。

Since the advent of aviation, aircraft have been operated with carbon-based fuels such as gasoline or kerosene. Though these fuels generate high power, they come with unpleasant effects such as increased production of greenhouse gasses. Therefore, aircraft OEMs have endeavored to find new ways to address such challenges and one of the solutions that have emerged is the development of more electric aircraft (MEA). MEA are advanced aircraft that use a large number of electrical components to reduce the non-propulsive power systems such as mechanical, hydraulic, and pneumatic systems, all of which derive its power from the aircraft engine. This, conceptually, reduces the weight of aircraft, leading to a low cost of ownership, use of less fuel, reduction in emissions, increased reliability, and several other added benefits.

Military aerial refueling (also called air-to-air refueling) is the process of pumping aviation fuel from a military tanker to another military air platform during the flight. This process allows the receiving aircraft to remain airborne for a longer duration, supplementing the mission effectiveness. Owing to the growing investments in developing long-range aircraft, the importance of maintaining sturdy fleets of aerial refueling tankers has revived its importance among the defense ministries of many countries across the globe.

After the Second World War, MPA were primarily designed for long-range patrolling to track and hunt down submarines. In the 1990s, they evolved to carry out surveillance either at sea or in the coastal regions. After 9/11, the US and its allies used MPA for reconnaissance and battlespace surveillance. Thus, MPA have transitioned from submarine trackers to performing anti-submarine warfare (ASW) and anti-surface warfare (ASUW) missions, and now even to multi-mission MPA.

Marine outboard engines are generally used in powerboats. Almost all powerboats are now equipped with either inboard or outboard engines. The demand for outboard engines is more than inboard engines. In Europe, 80% of the total engines used are outboard engines. In the US, the demand for outboard engines is on the same line as in Europe. In Europe, the demand for diesel engines is more, whereas the American market is dominated by gasoline engines. Another major difference between these markets is that consumers in the European market prefer low power output outboard engines, whereas consumers in the US prefer high power output outboard engines.
