国外的信息渠道是公开的,北航学生能看到的,别人也可以看到,至少我这个以前专门搞技术情报的可以很方便看到,在国外的内容上可以看得比北航更多
F-16开加力才能跟上F-35基本是胡说,推重比某个程度上就代表了飞机的加速性
如果这个没错的话,绝不能小瞧F-35的机动性
Comments on the september 15. AA-1 test flight by LMs chief test pilot, Jon Beesley. The flight was conducted to test performance and handling with full internal weapon stores of 5000 pounds:
I had the opportunity yesterday to fly the F-35 for the first time with the INTERDICTION COMBAT load of 2-GBU 31 (2000# bombs) and 2 AIM -120 missiles. In current fighters there is an expectation of performance degradation when carrying 5000# of ordinance but the internal carriage made any degradation hard to discern.
The acceleration in MAX AB takeoff was very quick and interestingly there is an increase in the acceleration rate above 120 KCAS. The takeoff roll was very near to the 3500’ prediction. Once airborne I came out of AB relatively soon after lift off and continued to climb and accelerate in MIL power in a 10 deg to 15 deg climb attitude. There was plenty of performance. The climb out with full internal weapons carriage was particularly impressive to me.
The climb rate seemed to be only slightly hindered by the stores carriage with climb angles near 15 deg in MIL power while in a 30 deg bank turn back over the field. Very pleasant to see clean fighter climb rates and angles while carrying a combat load. The chase aircraft still required brief inputs into AB to keep up with me. This is especially impressive because the 325 KCAS climb speed is well below the optimum climb speed profile for the aircraft.
We only did a brief handling qualities test point on this mission but the handling qualities with this combat loading were indistinguishable from the aircraft with no stores.
Landing occurred with 4500# of fuel and was easily stopped inside of an 8000 ft. runway length with brake temperatures cool enough to taxi straight back to the hangar.
转贴人加了一个注解说:
Note that 8000 ft. refers to the runway length, not the stopping distance.
Chase was an F-16 with "most powerful engine" and no weapon stores.
Take off fuel was 13000 pounds.
F-35办公室的网站
其中F-35 Joint Strike Fighter Media Kit Statistics是“正式”的数据。
相差快7%了,不是一个小数字,或许是PW设计191,但F-35办公室只“指望”178?不懂。
首先,这是Code One里的文章摘录,而Code One是什么捏?那是LM的官方杂志,不能说他们编造,但挑好的说是肯定的。怎么挑呢?比方说,这里说10-15度爬升,那是跟民航机一样九斤老太的爬升法,民航机要尽快空出空域,有时还要更大角度爬升呢。问题是,F-35A是从跑道上开加力起飞,拉起后才转入军推。但伴飞的F-16是什么状态开始的呢,开始位置呢?应该说,F-16应该在稍后的位置,否则看不清;应该最低速度,否则F-35还在滑跑就冲过头了。这样,F-35拉起后爬升,F-16要尽快从最低速度(可能还是大迎角)状态跟上,开一点加力没有什么奇怪。
F-35在约3500英尺处拉起,1100米左右,开了加力了,滑跑不短。哪天用书上看来的公式算一算起飞时的升阻比。
60周年月饼时候那么多飞机会和都分秒不差呢
只要距离和位置控制的好就不会冲过头,没必要最低速度飞
参照F-16的起飞速度120~130节的话,
至少在F-35以325节表速爬升时候,已经离地有阵子了,伴飞的F-16有足够时间加入编队
而且注意下句话,F-35的爬升率潜力还有:
This is especially impressive because the 325 KCAS climb speed is well below the optimum climb speed profile for the aircraft.
我把你们这段对话称作:国外“土鳖”和国内“洋鳖”的对话,目前这段对话已经进入短兵相接的阶段。在cd上“洋鳖”最喜欢的“洋文资料”和“精确数据”pk。
我一直相信你等国外"土鳖"不似我等国内“土鳖”会怵这些“洋文资料”的~因为你们更熟悉“洋文”的文风,知道哪些洋文的可信度,甚至可以直接找到原文的出处从跟上进行剖析而不是看见就信了。
目前有“191~192千牛”和“f16开加力才跟上f35”的两个被国内论坛广为流传的数据在这里得到了一定的研究,目前我觉得这两个数据的可信度已经打了一定的折扣了~再接再厉~我等国内土鳖继续围观ing
而且是指40000磅class
另:老大,链接当成图片了
也有几个档次,不是一开加力就是最大推力。
(看一本图文科普书上,F14发动机就是4还是
5级加力档。)
阅兵时大家控制速度,没有人自说自话加速跑了。再说,匀速飞行时325的表速F-16用军推都维持不了?这太夸张了吧!
个人认为,如果不是飞行状态有猫腻,F-16平飞325的表速肯定不需要开加力,要不平飞M2就别指望了,不管在什么高度。
不说虚报的事,但一般来说,在你的项目遇到公关灾难的时候,你是会把数据压低了报呢,还是有多好就撑满?
