中国最大的飞机是名字
截止2019年，中国最大的飞机是C919。C919大型客机，全称COMACC919，是中国首款按照最新国际适航标准，具有自主知识产权的干线民用飞机，是由中国商用飞机有限责任公司于2008年开始研制的。
C是中国英文名称“China”的首字母，也是中国商飞英文缩写COMAC的首字母，第一个“9”的寓意是天长地久，“19”代表的是中国首型大型客机最大载客量为190座。

具体案例：
本次飞行初步检查了飞机起飞、着陆性能与各主要系统、设备的工作情况。飞行过程中检查了飞机襟翼收放、起落架系统、导航通信系统状态以及加减速特性等。
C919大型客机是中国按照与国际接轨的适航标准自主研制的150座级单通道干线飞机，2008年底完成项目可研论证，2015年11月在上海总装下线。其中，C919首架机于2017年5月5日在浦东国际机场完成“首飞”，又于2017年11月10日转场陕西阎良。
中国商飞公司民用飞机试飞中心102架机团队负责人毛为说，C919第二架客机自11月23日转入试飞阶段以来，先后开展低速滑行试验、中速滑行试验等，达到“首飞”条件。相比于首架机的“首飞“，今日无论是从飞行高度、飞行速度及任务点数量都有明显提升。
中国商飞公司民用飞机试飞中心总工程师王伟介绍，根据C919大型客机项目计划，共将投入6架试飞飞机进行试验试飞，2架飞机进行地面试验。6架试飞飞机需要完成1000多项符合性验证试验，2架地面试验飞机需要进行系统集成试验、全机静力试验和疲劳试验等。
中国商飞公司C919大型客机项目总经理吴跃表示，未来几年，商飞将联合中国航空工业集团等机构，以山东东营与陕西阎良两大试飞基地为主战场，在全国多地机场展开密集试飞。
这将是中国首次对150座级的干线飞机进行适航验证，C919大型客机也将接受中国航空工业领域等级最高的试飞验证考验。

美国航天飞机的两次失事事件
Spaceflight fatalities
The history of space exploration has been marred by a number of tragedies that resulted in the deaths of the astronauts or ground crew. As of 2007, in-flight accidents have killed 18 astronauts, training accidents have claimed 11 astronauts, and launchpad accidents have killed at least 71 ground personnel.[dated info]
About two percent of the manned launch/reentry attempts have killed their crew, with Soyuz and the Shuttle having almost the same death percentage rates. Except for the X-15 (which is a suborbital rocket plane), other launchers have not launched sufficiently often for reasonable safety comparisons to be made.
About five percent of the people that have been launched have died doing so (because astronauts often launch more than once). As of November 2004, 439 individuals have flown on spaceflights: Russia/Soviet Union (96), USA (277), others (66).[citation needed] Twenty-two have died while in a spacecraft: three on Apollo 1, one on Soyuz 1, one on X-15-3, three on Soyuz 11, seven on Challenger, and seven on Columbia. By space program, 18 NASA astronauts (4.1%) and four Russian cosmonauts (0.9% of all the people launched) died while in a spacecraft.[dated info]
In total, Shuttle accidents have claimed the lives of fourteen.
Soyuz accidents have claimed the lives of four. No deaths have occurred on Soyuz missions since 1971, and none with the current design of the Soyuz. Including the early Soyuz design, the average deaths per launched crew member on Soyuz are currently under two percent. However, there have also been several serious injuries, and some other incidents in which crews nearly died.
NASA astronauts who have lost their lives in the line of duty are memorialized at the Space Mirror Memorial at the Kennedy Space Center Visitor Complex in Merritt Island, Florida. Cosmonauts who have died in the line of duty under the auspices of the Soviet Union were generally honored by burial at the Kremlin Wall Necropolis in Moscow. It is unknown whether this remains tradition for Russia, since the Kremlin Wall Necropolis was largely a Communist honor and no cosmonauts have died in action since the Soviet Union fell.
There have been four fatal in-flight accidents on missions which were considered spaceflights under the internationally accepted definition of the term, plus one on the ground during rehearsal of a planned flight. In each case all crew were killed. To date, there has never been an incident where an individual member of a multi-member crew has died during (or while rehearsing) a mission.
1967 April 24: parachute failure: Soviet cosmonaut Vladimir Komarov died on board Soyuz 1. His one-day mission had been plagued by a series of mishaps with the new type of spacecraft, which culminated in the capsule's parachute not opening properly after atmospheric reentry. Komarov was killed when the capsule hit the ground.
1971 June 30: crew exposed to vacuum of space: The crew of Soyuz 11, Georgi Dobrovolski, Viktor Patsayev and Vladislav Volkov, were killed after undocking from space station Salyut 1 after a three-week stay. A valve on their spacecraft had accidentally opened when the service module separated, which was only discovered when the module was opened by the recovery team. Technically the only fatalities in space (above 100 km).
1986 January 28: structural failure after lift-off: The first U.S. multiple in-flight fatalities. The Space Shuttle Challenger was destroyed 73 seconds after lift-off on STS-51-L. Analysis of the accident showed that a faulty O-ring seal had allowed hot gases from the shuttle solid rocket booster (SRB) to weaken the external propellant tank, and also the strut that held the booster to the tank. The tank aft region failed, causing it to begin disintegrating. The SRB strut also failed, causing the SRB to rotate inward and expedite tank breakup. Challenger was thrown sideways into the Mach 1.8 windstream causing it to break up in midair with the loss of all seven crew members aboard: Greg Jarvis, Christa McAuliffe, Ronald McNair, Ellison Onizuka, Judith Resnik, Michael J. Smith, and Dick Scobee. NASA investigators determined they may have survived during the spacecraft disintegration, while possibly unconscious from hypoxia; at least some of them tried to protect themselves by activating their emergency oxygen. Any survivors of the breakup were killed, however, when the largely intact cockpit hit the water at 200 mph (320 km/h). See Space Shuttle Challenger disaster.
2003 February 1: structural failure during re-entry: The Space Shuttle Columbia was lost as it reentered after a two-week mission, STS-107. Damage to the shuttle's thermal protection system (TPS) led to structural failure in the shuttle's left wing and, ultimately, the spacecraft broke apart. Investigations after the tragedy revealed the damage to the reinforced carbon-carbon leading edge wing panel had resulted from a piece of insulation foam breaking away from the external tank during the launch and hitting shuttle's wing. Rick D. Husband, William McCool, Michael P. Anderson, David M. Brown, Kalpana Chawla, Laurel B. Clark, and Ilan Ramon were killed. See Space Shuttle Columbia disaster.
There has also been a single accident on a flight which was considered a spaceflight by those involved in conducting it, but not under the internationally accepted definition:
1967 November 15: control failure: Michael J. Adams died while piloting a North American X-15 rocket plane. Major Adams was a U.S. Air Force pilot in the NASA/USAF X-15 program. During X-15 Flight 191, his seventh flight, the plane first had an electrical problem and then developed control problems at the apogee of its flight. The pilot may also have become disoriented. During reentry from a 266,000 ft (50.4 mile, 81.1 km) apogee, the X-15 yawed sideways out of control and went into a spin at a speed of Mach 5, from which the pilot never recovered. Excessive acceleration led to the X-15 breaking up in flight at about 65,000 feet (19.8 km))[1]. Adams was posthumously awarded astronaut wings as his flight had passed an altitude of 50 miles (80.5 km) (the U.S. definition of space).
在太空探索的历史，并导致其中一个悲剧，在航天员或地面人员造成的死亡人数。截至2007年，在飞行中意外死亡18宇航员，训练事故已造成11个宇航员，并启动事故已造成至少71名地勤人员。日消息] [
约百分之二的载人发射/再入企图杀死他们的船员和联盟号航天飞机与具有几乎相同的死亡百分比率。除了在X - 15（这是一个亚轨道火箭飞机），其他发射器没有足够的启动往往比较合理的安全需要作出。
约5个已发起民众死亡这样做（因为宇航员经常开展一次以上）。截至2004年11月，439人已经出动了上太空飞行：俄罗斯/前苏联（96），美国（277），其他（66）。[编辑] 22人死亡，而在航天器：在阿波罗1号，1 3在联盟1号，在X - 15 - 3，联盟11号3，对挑战者七个，七宗在哥伦比亚。由太空计划，美国航天局宇航员18（4.1％）和4（0.9％的人所有的发射）死亡时，在航天器。[日消息]俄罗斯宇航员
整体而言，航天飞机事故已造成14死亡。
联盟事故已造成4的生命。无死亡病例发生在联盟特派团自1971年以来，与该联盟目前的设计没有。包括早期联盟的设计，每推出机组人员对联盟目前正在死亡的平均百分之二。不过，也有过几次严重受伤，其中一些接近死亡船员的其他事件。
美国宇航局谁失去了在执行公务而捐躯的宇航员是在太空镜上奏纪念在肯尼迪航天中心参观的梅里特岛，佛罗里达情结。谁在执行任务时死在苏联的支持下宇航员一般荣幸葬在克里姆林宫墙墓地在莫斯科举行。目前还不清楚这是否仍然对俄罗斯的传统，因为克里姆林宫墙墓地，主要是一个荣誉，没有共产党的宇航员在行动中死亡，因为苏联下跌。
目前已有4人死亡上审议航天飞行术语下，国际公认的定义，以及在有计划的飞行排练地上一任务的飞行事故。在每一种情况下，所有船员被打死。迄今为止，从来没有一个地方是一个多机组成员个别成员死亡时（或在排练）特派团的事件。
1967年4月24日：降落伞失败：前苏联宇航员弗拉基米尔科马罗夫死亡船上联盟1。他1天的任务已经困扰了事故的航天器，它在太空舱的降落伞最终再入大气层后，不能正确打开新类型系列。科马洛夫被打死时，胶囊撞到地面。
1971年6月30日：暴露于真空宇航员：该联盟11号，格奥尔基Dobrovolski，尤Patsayev和弗拉季沃尔科夫船员被杀害后，从空间站礼炮1号脱开后三个星期的逗留。关于他们的航天器阀门不小心打开时，服务舱分离，这是该模块时，才发现是由回收队打开。在空间技术上的唯一死亡人数超过100公里（）。
1986年1月28日：结构失败后剥离：一是美国的多个飞行中死亡。挑战者号航天飞机被摧毁73秒后剥离在STS - 51 - L的。事故分析表明，一个错误的O形圈密封曾允许从航天飞机固体火箭助推器（SRB）之热气体削弱外部推进剂贮箱，也是支撑这举行的助推器的坦克。坦克尾部区域的失败，导致它开始瓦解。国家储备局支撑也没有，造成储备局向内旋转坦克和加速解体。挑战者将被抛出侧身1.8马赫导致它在空中打破了同船上7名船员全部损失：格雷格贾维斯，克丽斯塔麦考利夫，罗纳德捷，埃利森鬼冢，朱迪思雷斯尼克，迈克尔J ·史密斯，迪克斯科比Windstream的。美国宇航局的研究人员确定他们可能在飞船解体存活，而可能是由缺氧昏迷，至少其中一些试图保护他们的紧急氧气通过激活自己。任何生还者的解体被打死，但是，当大部分完好无损驾驶舱打击200英里每小时（320公里/小时）的水。见挑战者号航天飞机灾难。
2003年2月1日：结构故障在重返大气层：哥伦比亚号航天飞机失去了，因为它经过两个星期的使命重返，执行STS - 107。损坏航天飞机的热防护系统（TPS）的失败导致了结构性航天飞机的左翼，最终，飞船解体。惨剧发生后的调查揭示了在钢筋混凝土中碳碳机翼前缘面板的损害已经造成破坏的绝缘距离从外部燃料箱在发射过程中一块泡沫材料击中航天飞机的机翼。里克四丈夫，威廉麦库尔，迈克尔P.安德森，大卫布朗，研究员Kalpana Chawla的，乙劳雷尔克拉克，和宜兰拉蒙被杀害。见哥伦比亚号航天飞机灾难。
同时也出现了一对被认为是由那些参与开展航天飞行单一事故，但不属于国际公认的定义：
1967年11月15日：控制失败：迈克尔J.亚当斯去世时驾驶一北美国X - 15火箭飞机。亚当斯是美国主要的空军在美国航天局/美国空军X - 15的试验计划。在X - 15的飞行191，他的第七次飞行，这架飞机第一次有一个电子故障，继而在其飞行远地点控制问题。该试验还可能迷失方向。在从二六六零零零英尺（50.4英里，81.1公里）远地点再入中，X - 15 yawed侧身失控，变成了一个旋转的马赫5，从这些试验没有恢复的速度。导致过度加速的X - 15在飞行中打破了约65,000英尺（19.8公里））[1]。亚当斯被追授为他的翅膀飞行宇航员已经通过了50英里（80.5公里）（美国定义的空间）的高度。
C191才座不到200人怎么算是大飞机
因为C919在条件上已经完全符合了大飞机的标准。从座席上来说，根据国际通用的专业标准，飞机的座席超过150座就属于大飞机，C919的座席为168座，是“不折不扣”的大飞机。
其次，从航程上来说，C919的航程共有5555公里，基本可以覆盖国内的主要二线城市，所以其飞行的覆盖面也非常“大”。“C919使用了大量先进材料，在满足强度、刚度等前提下，减轻了不少重量。据估算，飞机每降低1%的结构重量，航空公司每年就可以节省十几万，甚至几十万的燃油花费，因此C919节省的开销也很“大”。
扩展资料：
C919的优点：
1、采用先进气动布局和新一代超临界机翼等先进气动力设计技术，达到比现役同类飞机更好的巡航气动效率，并与十年后市场中的竞争机具有相当的巡航气动效率；
2、采用先进的发动机以降低油耗、噪声和排放；
3、采用先进的结构设计技术和较大比例的先进金属材料和复合材料，减轻飞机的结构重量；
4、采用先进的电传操纵和主动控制技术，提高飞机综合性能，改善人为因素和舒适性；
5、采用先进的综合航电技术，减轻飞行员负担、提高导航性能、改善人机界面；
6、采用先进客舱综合设计技术，提高客舱舒适性；
7、采用先进的维修理论、技术和方法，降低维修成本。
