第176章 划时代的客机（一）

不过arj21700最大的商载梁远可是印象深刻，8935千克，当时梁远还和蔡晓兵开玩笑的说过，只差yidiǎn点就能达到9吨级了，也不zhidào商飞的技术人员会不会因此损失一大笔奖励。
mpc75100的最大起飞重量是39950千克，最大零油重量35350千克，使用重量为24500千克，结构重量只有10850千克，梁远心算了一下，发觉mpc75100的最大商载为10850千克，yidiǎn不掺假的十吨级别。
想着arj21700基本型的航程为2225公里，而mpc75100基本型的航程为2963公里，梁远叹了口气，就算是外行也能一眼看出，两者根本就不是一代飞机，这才是航空工业的真正技术实力，也是航空工业的核心竞争力。
不过这差距也太大了，arj21700装了6吨多的油，居然跑不过装了4.6吨油的mpc75100，虽说人yijing穿了过来，梁远还是觉得心里直冒寒气。
赶紧向后翻了翻资料，才发觉mpc75的巡航速度只有0.77马赫，需要的单发推力只有62.3kn，而arj21的巡航速度高达0.82马赫，单发推力也高达74.87kn，梁远这才释然。
不过转念一想，梁远又觉得商飞有些混帐，0.82马赫和0.77马赫的区别，大约是871公里/小时和818公里/小时的区别，真不zhidào快53公里/小时的速度，值不值得花费这么大的代价去争取？
或是事实是最糟糕、最残酷的那种arj21的气动效率真的一般得很？或是商飞还méiyou自主设计大型客机的实力，只能仿造md90jinháng照猫画虎？
不过这些暂时都和ziji无关了，梁远微微摇了摇头，把思绪拉回了ziji目前所处的时代。
也不zhidào共和国现在组装麦道82的最大商载是多少，梁远有些好奇的猜测着，此时的共和国航空工业根本没树立起商业服务的理念，纯属用官本位的思维在决定着共和国航空工业的一切。
哪怕是算上ri后的md90，除了顶着大型干线客机这个好听的名字，有利于政绩之外，在费效比上能不能追上mpc75都是两可之间。
想着后世市场化许久的民航，拒绝接受共和国ziji组装的md90客机的种种事情，梁远有些无奈的苦笑了一下。
对于八十年代的共和国航空工业来说，我把飞机造出来，你拿去用就ok了，至于使用的经济xing，可维护xingshime的关我屁事。
还好，ziji来了，梁远有些庆幸的想着。
不过mpc75客机在全球航空工业中到底处于shime水平呢，梁远不仅对手中资料剩余的部分兴趣大起。
ziji在国内收集的联邦德国关于mpc75的公开报道，可是一直强调mpc75支线客机所使用的动力引擎是跨时代的浆扇发动机，采用的发动机安装方式也是尾吊形式。
只有mbb集团总裁安东尼?托马斯，曾在答记者问题时说过，不排除使用涡扇发动机作为mpc75动力系统的kěnéng，不过这种kěnéng是极其微小的，结果，刘文岳第一次参观mbb的工厂，联邦德国方面就搞出了这么一份文件，看起来这中间的故事应该是有许多许多。
ps：注1：就是客机在机场经停，jinháng上、下客，上、下货物，加油、对航空发动机等机载设备jinháng例行检查等业务。
注2：指的就是一架客机在装上座椅、厨房、卫生间、衣帽间等飞行营运所必须的设备后，达到的空载质量，也意味着配备上机组人员客机mǎshàng可以投入营运。
注3：mpc75客机资料的准确xing大家不用怀疑，满楼搞来了当初德国佬的工程计划，资料的真实xing可以保证，唯一值得疑虑的，就是德国航空工业有méiyou完成这个计划的技术实力罢了。
