本文目錄一覽:

中國最大的飛機(jī)是名字

截止2019年,中國最大的飛機(jī)是C919。C919大型客機(jī),全稱COMACC919,是中國首款按照最新國際適航標(biāo)準(zhǔn),具有自主知識(shí)產(chǎn)權(quán)的干線民用飛機(jī),是由中國商用飛機(jī)有限責(zé)任公司于2008年開始研制的。

C是中國英文名稱“China”的首字母,也是中國商飛英文縮寫COMAC的首字母,第一個(gè)“9”的寓意是天長地久,“19”代表的是中國首型大型客機(jī)最大載客量為190座。

擴(kuò)展資料:

具體案例:

本次飛行初步檢查了飛機(jī)起飛、著陸性能與各主要系統(tǒng)、設(shè)備的工作情況。飛行過程中檢查了飛機(jī)襟翼收放、起落架系統(tǒng)、導(dǎo)航通信系統(tǒng)狀態(tài)以及加減速特性等。

C919大型客機(jī)是中國按照與國際接軌的適航標(biāo)準(zhǔn)自主研制的150座級(jí)單通道干線飛機(jī),2008年底完成項(xiàng)目可研論證,2015年11月在上??傃b下線。其中,C919首架機(jī)于2017年5月5日在浦東國際機(jī)場(chǎng)完成“首飛”,又于2017年11月10日轉(zhuǎn)場(chǎng)陜西閻良。

中國商飛公司民用飛機(jī)試飛中心102架機(jī)團(tuán)隊(duì)負(fù)責(zé)人毛為說,C919第二架客機(jī)自11月23日轉(zhuǎn)入試飛階段以來,先后開展低速滑行試驗(yàn)、中速滑行試驗(yàn)等,達(dá)到“首飛”條件。相比于首架機(jī)的“首飛“,今日無論是從飛行高度、飛行速度及任務(wù)點(diǎn)數(shù)量都有明顯提升。

中國商飛公司民用飛機(jī)試飛中心總工程師王偉介紹,根據(jù)C919大型客機(jī)項(xiàng)目計(jì)劃,共將投入6架試飛飛機(jī)進(jìn)行試驗(yàn)試飛,2架飛機(jī)進(jìn)行地面試驗(yàn)。6架試飛飛機(jī)需要完成1000多項(xiàng)符合性驗(yàn)證試驗(yàn),2架地面試驗(yàn)飛機(jī)需要進(jìn)行系統(tǒng)集成試驗(yàn)、全機(jī)靜力試驗(yàn)和疲勞試驗(yàn)等。

中國商飛公司C919大型客機(jī)項(xiàng)目總經(jīng)理吳躍表示,未來幾年,商飛將聯(lián)合中國航空工業(yè)集團(tuán)等機(jī)構(gòu),以山東東營與陜西閻良兩大試飛基地為主戰(zhàn)場(chǎng),在全國多地機(jī)場(chǎng)展開密集試飛。

這將是中國首次對(duì)150座級(jí)的干線飛機(jī)進(jìn)行適航驗(yàn)證,C919大型客機(jī)也將接受中國航空工業(yè)領(lǐng)域等級(jí)最高的試飛驗(yàn)證考驗(yàn)。

美國航天飛機(jī)的兩次失事事件

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).

C191才座不到200人怎么算是大飛機(jī)

因?yàn)镃919在條件上已經(jīng)完全符合了大飛機(jī)的標(biāo)準(zhǔn)。從座席上來說,根據(jù)國際通用的專業(yè)標(biāo)準(zhǔn),飛機(jī)的座席超過150座就屬于大飛機(jī),C919的座席為168座,是“不折不扣”的大飛機(jī)。

其次,從航程上來說,C919的航程共有5555公里,基本可以覆蓋國內(nèi)的主要二線城市,所以其飛行的覆蓋面也非?!按蟆薄!癈919使用了大量先進(jìn)材料,在滿足強(qiáng)度、剛度等前提下,減輕了不少重量。據(jù)估算,飛機(jī)每降低1%的結(jié)構(gòu)重量,航空公司每年就可以節(jié)省十幾萬,甚至幾十萬的燃油花費(fèi),因此C919節(jié)省的開銷也很“大”。

擴(kuò)展資料:

C919的優(yōu)點(diǎn):

1、采用先進(jìn)氣動(dòng)布局和新一代超臨界機(jī)翼等先進(jìn)氣動(dòng)力設(shè)計(jì)技術(shù),達(dá)到比現(xiàn)役同類飛機(jī)更好的巡航氣動(dòng)效率,并與十年后市場(chǎng)中的競(jìng)爭(zhēng)機(jī)具有相當(dāng)?shù)难埠綒鈩?dòng)效率;

2、采用先進(jìn)的發(fā)動(dòng)機(jī)以降低油耗、噪聲和排放;

3、采用先進(jìn)的結(jié)構(gòu)設(shè)計(jì)技術(shù)和較大比例的先進(jìn)金屬材料和復(fù)合材料,減輕飛機(jī)的結(jié)構(gòu)重量;

4、采用先進(jìn)的電傳操縱和主動(dòng)控制技術(shù),提高飛機(jī)綜合性能,改善人為因素和舒適性;

5、采用先進(jìn)的綜合航電技術(shù),減輕飛行員負(fù)擔(dān)、提高導(dǎo)航性能、改善人機(jī)界面;

6、采用先進(jìn)客艙綜合設(shè)計(jì)技術(shù),提高客艙舒適性;

7、采用先進(jìn)的維修理論、技術(shù)和方法,降低維修成本。

飛機(jī)機(jī)型 191/190 是什么機(jī)型?

是巴西航空工業(yè)生產(chǎn)的ERJ系列飛機(jī),是一種能坐100人左右的支線飛機(jī)。

ERJ系列飛機(jī)從2004年開始使用,到目前為止唯一一次有人員傷亡的事故就是河南航空伊春空難。

這個(gè)系列的機(jī)型(包括ERJ170/175/190/195)一共生產(chǎn)了660架,天津航空現(xiàn)有26架ERJ190在運(yùn)營,另外還有24架訂單,是ERJ系列比較大的客戶。
