超级军网为什么那么多人说J-8高空高速性能好尼？
来源：百度文库 编辑：超级军网 时间：2024/04/27 13:33:38
最近中俄军演，很多J-8，肥豹的贴子满天飞。我总是很奇怪，为什么有那么多人说J-8高空高速性能好，并且总是和Mig-25/31相提并论，Mig-25可是能飞到3马赫的实用战斗机。按照wiki的数据，作为截击机的J-8无论在爬升率，最大升限都弱于F-4鬼怪，只有极限速度和加力推重比高出一点点，何况F-4是双座战机。J-8高空高速性能好根本没有任何数据支持，或者说是比较的对象不同（J-8跟J-6比的话，高空高速性能肯定是好：），所以恳请哪位大大解释一下J-8高空高速好到底在哪里？

英语没学好，看不懂……
可能是跟国内其他机型相比吧，放到世界范围并不突出。
8的高空高速性能跟米格-25根本不能比，跟F-4也没有任何优势。顶多是一个二代机的达标水准
J-8高空高速性能好？？百字机笑了。。。。
（J-8跟J-6比的话，高空高速性能肯定是好：），
————还真就是跟J6比
————还真就是跟J6比
和他自己的低空低速性能相比，还是高空高速性能好一些。
到现在为止，82的准确数据好像还没有啵
8的高空高速性能跟5、6、7相比，当然算是好的了啊
三代机装备TG之前，J-8家族是最好的国产歼击机了
仔细看推力数据，就好在那里了，呵呵:D
注意实用升限(Service ceiling)的数据，这个J8确实在战斗机里算是非常突出的,比F-4,F-15,SU-27什么的全高不少.
这种极为抽象的烂数据有啥好比的
要直观，上几张3G、5G机动的包线图吧

可是就在Service ceiling上也没有超过F-22A的65,000 ft啊，8爷如何在高空“痛宰”猛禽呢？:D

不对吧?
即使按照LZ给的实际上减少了的数据,在Service ceiling上也超过了65000FT呀?{:3_96:}
科普下,1FT大约等于0.3048米,65000FT差不多是19812米吧.{:3_87:}

算了吧F-15带个死沉的ASAT还能飞到24000米发射，J-8II空机能飞那么高吗？
歼8静升限还算高，动升限非常垃圾，远远远不如F15、F4。
F4动升限都能冲上二万九！歼8貌似只有二万二
歼八所谓的高空高速优势对大部分二代机，以及象F15这样的三代机都非常小或者说甚至没有（哪怕就是最大亮点静升限也不过高了一两千而已，而动升限远远不如）。至于F22，没F22快也没F22高，怎么个枪挑法？

67,256 < 65,000
:victory:
因有人请客，我今天先编程，明天饭局归来，再来此观察。
f22在中国绝对有用歼8截击的战法，就仗着这点高度差来抽你们美国人呢。
另外有人拿歼六和八爷比，我觉得八爷虽好，但地位确实没有歼六高。

MIG25到M3也不算是实用范围了:sleepy:
米格25的侦查型号到了M3也会严重损坏发动机,时间长了甚至要整架飞机报废.
{:3_77:}那除了这个八爷还有什么拿得出手的？如果连这个名头都没有八爷还怎么混下去？八爷混不下去了很多人的饭碗怎么办？LZ不要随便泄漏我们的战略机密。

歼8好歹还有自主知识产权...
窃以为八爷的功劳在于：低产量、多改型，维系了沈飞这个团队
要是没了这个团队，拿来的11呢
