“M113 Family of Vehicles Mission Provide a highly mobile, survivable, and reliable tracked-vehicle platform that is able to keep pace with Abrams- and Bradley-equipped units and that is adaptable to a wide range of current and future battlefield tasks through the integration of specialised mission modules at minimum operational and support cost. Entered Army Service 1960 Description and Specifications After more than four decades, the M113 family of vehicles (FOV) is still in service in the U.S. Army (and in many foreign armies). The original M113 Armoured Personnel Carrier (APC) helped to revolutionise mobile military operations. These vehicles carried 11 soldiers plus a driver and track commander under armour protection across hostile battlefield environments. More importantly, these vehicles were air transportable, air-droppable, and swimmable, allowing planners to incorporate APCs in a much wider range of combat situations, including many "rapid deployment" scenarios. The M113s were so successful that they were quickly identified as the foundation for a family of vehicles. Early derivatives included both command post (M577) and mortar carrier (M106) configurations. Over the years, the M113 FOV has undergone numerous upgrades. In 1964, the M113A1 package replaced the original gasoline engine with a 212 horsepower diesel package, significantly improving survivability by eliminating the possibility of catastrophic loss from fuel tank explosions. Several new derivatives were produced, some based on the armoured M113 chassis (e.g., the M125A1 mortar carrier and M741 "Vulcan" air defence vehicle) and some based on the unarmoured version of the chassis (e.g., the M548 cargo carrier, M667 "Lance" missile carrier, and M730 "Chaparral" missile carrier). In 1979, the A2 package of suspension and cooling enhancements was introduced. Today's M113 fleet includes a mix of these A2 variants, together with other derivatives equipped with the most recent A3 RISE (Reliability Improvements for Selected Equipment) package. The standard RISE package includes an upgraded propulsion system (turbocharged engine and new transmission), greatly improved driver controls (new power brakes and conventional steering controls), external fuel tanks, and 200-amp alternator with four batteries. Additional A3 improvements include incorporation of spall liners and provisions for mounting external armour. The future M113A3 fleet will include a number of vehicles that will have high speed digital networks and data transfer systems. The M113A3 digitisation program includes applying hardware, software, and installation kits and hosting them in the M113 FOV.

“飞机是可以利用反向推力驶离航站楼的。一个简单的手段就可以实现，将导流装置放置于飞机引擎后，这会产生强劲的气流推动飞机的前身。通常，反推力都用在飞机着陆时，以帮助其减速——当飞机触地时，你能听见引擎突然的喘振，这时，反推力就开始工作了。但是，当飞机距离航站楼很近时，这个方法就不适用了。引擎产生的强大气流很可能会卷起地面上的杂物，猛烈地撞击到建筑物的玻璃，这也是机场为什么会转而使用拖车的原因了。”

“贝尔雅柯夫于1919年3月4日出生于穆罗姆市，1941年毕业于莫斯科航空学院，同年进入米格设计局工作。贝尔雅柯夫的一生就是米格设计局发展史的缩影，他参与了苏联时代全部米格战斗机的研制工作。1971年3月5日，贝尔雅柯夫成为米格设计局总设计师，此后在他领导下研制出了两种著名机型——米格-29战斗机与米格-31截击机。 米格设计局总设计师贝尔雅柯夫。 在贝尔雅柯夫上任前，舰载战斗机是雅克夫列夫设计局的“领地”，而贝尔雅柯夫却成了第一个与造船工业部建立合作关系的米格总设计师。1972年他接受了研制弹射起飞/拦阻降落的米格-23A舰载战斗机的任务。1973年贝尔雅柯夫决定正在研制中的米格-29应发展出舰载型米格-29K（此处K的含义是舰载，而苏联出口型军用飞机也常使用K编号，含义是商业，还有部分专门出口中国的飞机也使用K编号，含义是中国），后于1978年正式立项研制。1982年8月21日，米格-29KVP（含义是短距起降型）验证机完成了从T-1滑跃甲板起飞试验。1984年10月1日，米格-29KVP完成了从T-2滑跃甲板起飞试验。1984年初，贝尔雅柯夫正式决定将空军型米格-29M（设计局代号9.15工程）和海军舰载型米格-29K（设计局代号9.31工程）进行同步研制，这就意味着米格-29K将是一种具有多用途能力的战斗机。 出厂时无涂装的米格-29K舰载战斗机原型机。 贝尔雅柯夫对于米格-29K的定位是有着深谋远虑的。当时美国海军的主力舰载机型包括了F-14重型战斗机、F/A-18战斗攻击机、A-6攻击机。在苏联方面与之相对应，苏-27K是重型截击机，定位与F-14接近。米格-29K的地位相当于F/A-18，兼有截击机和强击机的功能。在贝尔雅柯夫看来F/A-18战斗攻击机必将首先淘汰A-6攻击机，进而淘汰F-14重型战斗机。当时苏-25K舰载强击机计划已经取消，贝尔雅柯夫坚信米格-29K必将战胜苏-27K。”

“既然与启动飞机引擎相比，飞机在滑行中的耗能要少得多，那为什么不用拖车将飞机直接拖到跑道的起点呢？2006年，维珍航空公司就想出了一个类似的主意。他们的想法是将飞机拖至跑道一端的“起步排位”（starting grid）处。”
