The need for safety systems has been an integral aspect since the advent of flights. They ensure the safe escape of pilots from any malfunctioning or damaged aircraft. The conventional escape systems consisted of only a recovery parachute. During the Second World War, the aircraft performances rapidly increased, which necessitated the escape systems for the crew to be equally fast. This led to the development of ejector seats. The traditional ejection seats were powered by a propellant-driven catapult.

AAVs are employed to conduct mechanized operations and for providing combat support in subsequent operations ashore. Such vehicles enable offshore shipping through rough seas and are alsocapable of traversing beaches, crossing rough terrain, and performing high-speed operations on roads. AAVs are equipped with armor to provide the ground combat element (GCE) as well as land and water operation capabilities. These vehicles are capable of restricting the enemies across land or water.

2015年是“十二五”与“十三五”的承接之年，我国政府对轨道交通产业的发展关注度持续增加。对内，在《关于加强城市轨道交通规划建设管理的通知》的指导下，各级城市纷纷加入到城市轨道交通的建设热潮当中，审批权的下放，对民间资本介入城市轨道交通建设与管理的放宽，都促进了国内城市轨道交通产业发展；对外，我国继续推行高铁“走出去”，包括雅万高铁、中老高铁、中泰高铁等项目均已启动，中国中车出口到马其顿的动车组项目于2015年7月正式下线，成为了中国动车组产品符合欧洲TSI(欧洲铁路互联互通技术规范)要求进入欧洲市场的第一单。

卫星导航产业作为重要的战略性新兴产业，受到了国家的高度重视。国务院及发展改革委、科技部、国家测绘地理信息局等相关部门都相继出台促进地理信息产业发展的扶持政策，以推动卫星导航产业的发展进程。

The global motorcycle industry has two segments — one consisting of highperformance motorcycles (considered as a luxury) and the other consisting of twowheelers used for commuting. Both these segments operate under contrast market dynamics and have different customer behavior and value chain. The premium segment is witnessing steady growth owing to the growing culture of touring motorcycling in mature markets such as the US, Japan, and Western Europe.

In aircraft, galleys are used as a compartment where food can be prepared to be served to the onboard passengers. The Douglas Aircraft Company was the first aerospace company to include it in its aircraft DC-3 in 1921. In commercial aircraft, the galleys typically not only include food preparation and serving equipment but also contain jump seats (for flight attendants) and emergency equipment.

Carbon brakes were originally used in military aircraft applications due to their low weight and high energy absorption capability. These were made widely available for commercial and civil aircraft in 1980. Historically, the cost association of carbon brakes was much higher than the conventional steel brakes, and their use was restricted to only large long-haul commercial aircraft.
