I can guarantee the production of ARJ-21 will not hit 15 planes per year.
It depends on demands and size of future production lines. MD-80 can be a good reference.I can guarantee the production of ARJ-21 will not hit 15 planes per year.
WHY NOT?I can guarantee the production of ARJ-21 will not hit 15 planes per year.
This plane will be outdated by 10 years later. It is trying to fill in the gap of domestic jetliner before C919 fully enter service. Maybe AVIC are waiting for C919 and purposely slow the domestic production of ARJ-21 so as not to waste money on this project.WHY NOT?
At present order level of 528 units, even at the production rate of 20 airplanes a year it still needs 26 years to fulfill the demand.
So what makes you so pessimistic about the future?
At the beginning of the new year, in the assembly shop of COMAC, six assembled domestic jet airliners ARJ21 crowded the production line. But today, the workers are facing a problem. They have to take apart the equipment in the newly installed cockpit.新年伊始,在中国商飞的总装车间里,6架组装中的国产支线喷气式客机ARJ21把生产线挤得满满当当。但今天,工人们却面临着一件麻烦事儿。他们要把刚装好的驾驶舱里的设备拆开。
中国商飞总装制造中心ARJ21项目负责人韩建宾说,它是里面所有电子电器设备和电缆集中的地方,前段时间做过一架,当时是用了6个人35天。
刚装好的设备就要拆开,让负责飞机总装的韩建宾着了急,改造一架飞机要耽误两架半飞机的生产,这样下去今年交付20架的生产任务肯定完不成。但这样的改动,在设计师看来是必须要改的。
中国商飞上海飞机设计研究院ARJ21副总设计师赵春玲说,这些问题主要是ARJ21运营验证过程中,从客户那儿提出来的。
ARJ21飞机飞行教员佟宇说,老构型大概在正常运行的时候有21盏白灯,如果出现飞机故障的情况下再有其他灯亮起,你不是很容易来识别。
飞行员希望灭掉这21盏灯,这样当故障提示灯亮起时,一眼就能找到问题出在哪儿了。像这样来自飞行员的细节建议,对于ARJ21的设计人员来说,也是第一次听到。一款飞行员不爱飞的飞机,是无法在市场上生存的。但要改这样一个小问题,飞机就得动大手术。
中国商飞上海飞机设计研究院ARJ21副总设计师赵春玲说,涉及到19个系统15家国内外供应商。光改线我们就改了1500多根线。
要对已经批量生产的飞机动这么大的手术,生产势必受到影响。退一步讲,其实不这样改进,按照原有标准装好的飞机也是可以交付给用户的。更快还是更优,面对这道选择题,韩建宾和同事们还是接受改进任务,稳扎稳打,让产品变得更好。
中国商飞总装制造中心ARJ21项目负责人韩建宾说,优化改造对于我们来说是必须的。因为我们面对的客户和竞争对手都是国际化的,大家的体验是我们必须要满足的要求。
One small but solid step for China Civil Aviation industry!
The C919 provides unconditional and comprehensive security alarms devices, and for the 737Max series, you will need to pay extra for expensive equipment.how does it compare to 737 Max in terms of benefit to airlines.
