very promising future in 2013 for c919
I wouldn't bet on that :(
when compare to other rivalsc919 sale = 380
russian mc21 = 248
japanese mrj = 165
Looks impressive, but let's take a look at the international sales figures;
C919 = 5% of sales to non-Chinese operators
MC-21 = 21% of sales to non-Russian operators
MRJ = 94% of sales to non-Japanese operators
As you can see, the others have broken the international market far better than Comac have.

2013年11月25日，C919大型客机翼身组合体综合验证项目中机身、外翼翼盒总装大部段在中航飞机西飞成功下线。
此次下线的C919大客翼身组合体大部段在核心制造技术上实现了多项突破：首次在国产机型上采用激光成型件加工中央翼缘条，首次采用铝锂合金材料加工机身蒙皮，采用20mm超厚机翼蒙皮数控喷丸成形技术、17m机翼折弯长桁加工技术。
下线仪式上，中国商飞公司副总经理、C919大型客机项目总设计师吴光辉代表中国商飞公司对中航工业及中航飞机西飞在C919项目研制工作中给予的大力支持、密切协作表示感谢，希望各参研单位继续团结一心、凝聚力量、攻坚克难，奋力推进项目研制。
中航工业副总经理耿汝光表示，中航工业将继续以高度的使命感和责任感，全力支持型号研制工作，力争让中国人自主研制的大型客机早日飞上蓝天。
中航飞机西飞总经理何胜强介绍了C919大客翼身组合体综合验证项目中机身、外翼翼盒大部段研制工作历程和下一步工作安排。
2012年2月，中国商飞公司确定西飞承担大型客机翼身组合体综合验证项目中机身、外翼翼盒大部段制造及翼身组合体总装任务。在各参研团队的共同努力下，2013年6月26日，C919翼身组合体综合验证项目中央翼上壁板开铆；9月-10月，中央翼、外翼翼盒、中机身总装相继开铆，11月25日翼身组合体综合验证项目“中机身、外翼翼盒大部段”顺利总装下线。
Is this already the first prototype or simply a test-module ?? :confused:

C919项目研制实现里程碑节点目标翼身组合体各大部段完成对接，顺利实现交付
本报讯 2月25日，中航工业西飞完成了C919大型客机翼身组合体各大部段对接，顺利实现交付，这表明大客翼身组合体综合验证项目已由机体结构制造阶段转入试验阶段，标志着大客项目研制实现了里程碑节点目标。
大客翼身组合体综合验证项目是为了化解大客飞机全机格兰特试验进度风险和技术风险，对多项关键设计及制造技术开展预验证的重要关键项目。2012年2月，作为C919大型客机主要的机体制造商，西飞全面启动了研制工作，并严格按照中国商飞质量要求，积极开展工程数据工艺审查，及时编发了制造一级网络计划和研制工艺工作二级网络计划，明确了技术准备、生产准备、零组件配套、总装装配等过程控制节点。技术团队大力开展新材料、新工艺、新技术科研攻关，突破了C919机翼下中壁板喷丸成型技术难关，全面掌握了大型复杂钛合金零件热处理变形控制技术，攻克了铝锂合金大型蒙皮和长桁加工技术难题，实现了龙骨梁、超级壁板等大部件的无余量装配。
在各方的全力配合和研制攻坚团队的奋力拼搏下，大客翼身组合体综合验证项目稳步推进。2013年6月26日，翼身组合体验证项目中央翼上壁板如期开铆；9月22日中央翼进入总装，外翼翼盒总装开铆；10月21日中机身进入总装；11月25日中机身、外翼翼盒大部段总装下线。截至目前，西飞先后完成了大客翼身组合体综合验证项目前机身、中机身、中后机身装配对接，外翼翼盒与机身装配对接，以及起落架安装等各大部段装配任务，并顺利实现交付。
翼身组合体综合验证项目是整个C919大型客机项目研制中首项核心大部件制造及装配项目，该项目的如期交付对拉动整个项目研制进度、突破制造技术障碍、加快各相关试验验证项目的全面启动起到了积极的促进作用。（吴宏伟）

C919 project development to achieve the milestone goal nodeLarge sections of wing and fuselage assemblies docking, smooth delivery
Newspaper News February 25, AVIC West completed the C919 large passenger aircraft wing-body combination of the big butt, smooth delivery, suggesting that large wing and fuselage assemblies integrated validation project has been created by the body construction phase to pilot phase, marked a big development projects to achieve the milestone goal node.
Large wing and fuselage assemblies integrated validation project is to address the bus grant of aircraft test schedule risk and technology risk, on a number of key design and manufacturing technology to verify the key projects. In February 2012, major airframe manufacturers as the C919 large passenger aircraft, XAC has started preparation work and in strict accordance with the quality requirements for commercial aircraft in China, actively carry out engineering information technology reviews, network planning and development process and disseminated in a timely manner to make level II network plan, defined the technical preparation, production, preparation, components, Assembly Assembly process control nodes. Technical team developing new materials, new processes, new technologies, scientific research and broke the C919 under the wing panels PEEN forming technical difficulties, have complete control over large and complex parts of titanium alloy heat treatment deformation control technology, captured the large aluminum-lithium alloy outer covering and trussed processing technical difficulties, achieved the keel beam, no margin for super large components such as wall assemblies.
In the development of the full cooperation of the parties and under assault team worked hard, large wing and fuselage assemblies integrated validation project was steadily advanced. On June 26, 2013, the wing-body configuration experience card project central wing panels on schedule to open the riveting; September 22 central wing entered the final Assembly, side wing and wing box Assembly rivet on October 21 entering the final Assembly of the fuselage on November 25 in the fuselage, wing and wing box assembly line outside. Up to now, XAC has completed comprehensive validation of a wing-body combination item in the fuselage, fuselage, rear fuselage Assembly and docking, the outer wing, fuselage and wing box Assembly and docking, as well as the installation of landing gear, and other major Assembly task, and successful delivery.
Wing-body combination integrated validation project is the first C919 large aircraft project development core parts manufacturing and Assembly projects, the timely delivery of the project to pull the entire project development schedule, break-through technology barriers, speed up the relevant test to verify that the project started has played a positive role in promoting.

Slowly ....
PICTURES: Comac confident of year-end roll-out for C919Comac says C919 suppliers are due to deliver all systems of the first aircraft by October, allowing the aircraft to be rolled out by the end of 2015.
Speaking to Flightglobal at Comac’s final assembly centre near Shanghai’s Pudong International airport, chief engineer Jiang Liping says assembly of the airframe is largely complete, and that installations of harnesses, cables and pipes has started.
The Chinese airframer has also taken delivery of its first CFM International Leap-1C engine, as well as the Liebherr landing gear. The aircraft's second powerplant is due to in September.
After roll-out, aircraft 101 needs to undergo a series of pre-flight preparations, including engine tests, lightning tests and taxi tests before it can make its first flight.
Under the best circumstances, pre-flight preparation could be completed within four months following roll-out, says Jiang. This means that the C919 could make its first flight around April or May of 2016.When Flightglobal visited the manufacturer's sub-assembly hangar, aircraft 101 was resting on struts with its wing-to-body join completed. Comac had removed the aircraft's tail cone, as well as its vertical and horizontal stabilisers as it had to strengthen the composite aft-fuselage, says Jiang. The aircraft's windows have also been replaced with smaller standard-size ones, after the manufacturer discovered that its original larger windows affect the strength of the fuselage.
The aircraft's radome as well as the winglets have not been attached. Jiang says the airframe will move to the final assembly hangar next month, where its engines will be attached and systems installed.
Next month, Comac will also start final assembly of aircraft 102 as well as a static strength test aircraft. The mid-fuselage of aircraft 102 has already been delivered, with other sections of the fuselage due to arrive by the end of the month.

Comac engages backup suppliers to prevent C919 delaysBy: Mavis Toh Shanghai 03:12 25 Aug 2015
Comac is using a dual supplier system to manufacture critical and potentially challenging parts of the C919 airframe, to ensure quality control and to prevent any major delays to the programme.
These include the aircraft's aft fuselage as well as its vertical and horizontal stabilisers, all of which are made of composites, Comac's chief engineer Jiang Liping tells Flightglobal in an interview in Shanghai.
She explains that Chinese suppliers are unfamiliar with the use of composites and that the airframer's concern is that the quality and strength of the parts produced by one supplier may not match the required standards.
An example is how the first aft fuselage delivered by Shenyang Aircraft Corporation had to be strengthened.
Comac also engaged two suppliers to build the C919's centre wingbox and mid fuselage due to anticipated complexities in the wing-to-body join of the aircraft.
"We do this so that we have a backup... the costs will go up but this is for quality control and also to ensure that the the programme's timeline is under control," says Jiang.
She adds, however, that Comac has stuck to the main suppliers thus far, since the manufactured parts have generally met standards.
Comac has largely completed the final assembly of the first flight test aircraft for the C919 programme, and is working towards a year-end roll-out followed by first flight in 2016.
