国产大飞机将于明天首飞!不少部件是咱们山东制造

在他看来,自由贸易港建设尚在探索阶段,推进应循序渐进,可先从沿海、沿江港口试点,在条件成熟时再向内陆地区的空港和无水港推进。

    核心提示:中国商飞公司5月3日发布消息称,综合各方面因素,国产大型客机C919将于5月5日在上海浦东国际机场首飞。如天气条件不具备,则顺延。

中国商飞公司5月3日发布消息称,综合各方面因素,国产大型客机C919将于5月5日在上海浦东国际机场首飞。如天气条件不具备,则顺延。

国产大型客机C919资料图

放飞评审4月中旬通过

从2007年2月国务院批复大型飞机研制重大科技专项正式立项,到2019-09-23C919总装下线,再到2019-09-23首飞,科研人员针对先进的气动布局、结构材料和机载系统,共规划了102项关键技术攻关,包括飞机发动机一体化设计、电传飞控系统控制律设计、主动控制技术等。

记者采访了解到,C919总装下线之后,项目在系统集成试验、静力试验、机上试验、试飞准备等几条主线稳步推进。为准备首飞,C919已完成118个试验项目,经历了包括低滑、中滑、高滑在内的21次滑行试验,并于2017年3月通过专家技术评审,4月通过放飞评审。

关于首飞日期的选择,中国商飞公司总经理贺东风此前表示,何时首飞将取决于各方面条件,包括天气状况、飞机和机组的状态等。

C919作为着眼于最主流的航空运输市场(150座级),完全按照国际主流适航标准和国际主流市场运营标准研制的干线飞机,受到国内外市场的关注。目前,C919大型客机拥有中国国际航空公司等23家国内外用户,订单总数570架,其中包括美国通用电气租赁(GECAS)等国际客户。

实际上,C919大型客机是我国建设创新型国家的标志性工程。此前,C919最初预设的首飞时间是2014年底或2015年初,后因从国外采购的航电、飞控、动力等关键子系统,以及国内研制生产的子系统之间的集成耦合难度大于预期,首飞时间只能推迟。之后,2016年年中、2016年年底,2017年年初、2017年首季等首飞时间,相继披露于媒体,直到今年2月6日出版的《人民日报》发布“预计今年上半年飞上蓝天”,才将首飞时间“锁定”。

之前C919的首飞时间为啥一再推迟?实际上,商用大客的安全性要求比军用大运更为苛刻。打个形象比喻,军用大运要求“皮实”,商用大客追求“精致”。为了确保首飞的“万无一失”,只能一再推迟。不过,现在看来,C919真正盛装登场的日子马上就要来了。

C919最大载客量190人 

据中国商飞介绍,“COMAC919”大型客机代号简称“C919”,“COMAC”为中国商用飞机有限责任公司英文名称简写,简称中的“C” 既是“COMAC”的第一个字母,也是中国的英文名称“CHINA”的第一个字母。第一个9寓意“天长地久”,19寓意C919大型客机最大载客量190 人。

C919飞机基本型全经济级布局为168座,混合级布局为158座,高密度布局174座。其标准航程型设计航程为2200海里(4075公里),增大航程型设计航程为3000海里(5555公里)。

设计经济寿命为80000飞行小时/48000起落架次/25个日历年。最大商载18900千克,标准商载15010千克。巡航速度0.78马赫,最大使用速度0.82马赫,最大飞行高度39800英尺(12131米),巡航高度35000英尺(10668米)。

飞机采用后掠下单翼,大展弦比、超临界机翼,正常式尾翼。翼吊两台高涵道比涡扇发动机。前三点可收放式起落架。全机长38.90米,翼展35.80米,全机高11.95米,主轮距7.62米,前主轮距13.47米。驾驶舱飞机采用两人驾驶体制,配置大屏幕液晶显示器(LCD),采用侧杆操纵。

飞机上不少部件是咱“山东造”

作为我国自主研制的新一代喷气式干线客机,C919从外形到内部布局都是中国自己设计完成的,其中综合航电、气动力设计等六大技术都居世界前列。相信很快,它就能装上自主研发的“大心脏”-中国制造的发动机,到2025年国产化率将超过90%。

据统计,国内有22个省市、200多家企业、36所高校、数十万产业人员参与了C919大型客机研制。

C919雷达罩首件开工仪式是2019-09-23,在济南第六三七研究所生产现场举行的,将为国产大飞机装上“济南眼睛”。并且济南的中航工业第六三七研究所也是C919大型客机项目的九大机体供应商之一,同时也是省内唯一为C919大型客机项目配套的供应商。此外,国家超算济南中心还为C919提供了高性能计算服务。

大飞机钛合金紧固件均由烟台研发。根据预测,C919成功进入市场后,总销量有望达到2000架次左右,随着C919国产化率的提高,烟台一公司可为单机提供价值上千万元的配套产品。“C919单机需要标准件109万件,其中,钛合金材料零部件需要20万件左右,将全部由咱们自主研发。”这意味着烟台将为国产大飞机提供近两成的标准件。

大小与波音737系列客机相似 客户已达23家订单570架

据北京青年报报道,C919大型客机是一种双引擎窄体飞机,大小与空客320和波音737系列客机相似。目前,拥有东方航空、南方航空等23家国内外用户,订单总数570架,其中包括美国通用电气租赁(GECAS)等国际客户。

昨日,中国商飞C919前方总指挥部宣布,我国具有完全自主知识产权的新一代大型喷气式客机C919计划5月5日在浦东机场首飞,如天气条件不具备则顺延。
