家园 喷气式发动机尾焰温度

活塞式发动机以及涡轮轴和涡轮螺旋桨发动机的排气温度比较低,但只适用于低速飞机.

高速飞机,在涡轮喷气和涡轮风扇两种发动机中,如果从满足飞行性能的要求出发,采用哪

一种发动机都是可以的话,应该选用后者.例如美国的"战斧"导弹YBGM-109,其战略型采

用的是F107-WR-100型涡轮风扇发动机,而其战术反舰型则用J402-CA-400型涡轮喷气发动

机.这两种发动机的推力相同,尺寸相近,但排气温度却相差很多.F107-WR-100涡轮风扇

发动机的排气温度为315℃,而J402-CA-400涡轮喷气发动机则高达787℃.

就算f86不开加力。。。。

至少也有两百多度,

这么高的温度进去。。。。

家园 When Push Came to Shove

AFA Magazine

May 1998, Vol. 81, No. 5

By John L. Frisbee, Contributing Editor

When Push Came to Shove

...The Air Force had a rescue detachment atCho Do Island, about 60 miles to the south-and with plenty of flak en route.

Risner decided to try something that, to his knowledge, had never been done

successfully before. He would push the damaged F-86 to Cho Do, where Logan

could bail out safely.

Risner told Logan to shut down his engine, now almost out of fuel. Then he

gently inserted the upper lip of his air intake into the tailpipe of Logan's

F-86. "It stayed sort of locked there as long as we both maintained stable

flight, but the turbulence created by Joe's aircraft made stable flight for

me very difficult. There was a point at which I was between the updraft and

the downdraft. A change of a few inches ejected me either up or down,"

Risner, now retired and living in Austin, Texas, recalls.

Each time Risner re-established contact between the battered nose of

his F-86 and Logan's aircraft was a potential disaster that was made even

more likely by the film of hydraulic fluid and jet fuel that covered his

windscreen and obscured his vision. It was, one imagines, something like

pushing a car at 80 miles an hour down a corduroy road in a heavy fog.

Miraculously, Risner nudged Joe Logan's F-86 all the way to Cho Do,

maintaining an airspeed of 190 knots and enough altitude to stay out of

range of automatic weapons. Near the island, Logan bailed out, landing in

the water near shore. Ironically, Risner's heroic effort ended in

tragedy. Although Logan was a strong swimmer, he became tangled in his chute

lines and drowned before rescuers could reach him. But the measure of a

heroic act lies not in success. It lies in the doing....

家园 据说前面那位把引擎关了
家园 “美空军中最知名的中国飞行员”是瞎掰。。。

老美根本没认这事。。。

家园 这件事很有名,应该不是假的

虽然僚机飞行员最后死了,但两人在推操作时的无线电通话,长机进气鼻的损坏情况,地面应该都是可以验证的。另外还有当他们接近接应点时接应飞机上的人员很可能有目击,总的来说吹牛的可能性不很大。其实操作起来和空中加油应该很类似。另外f86也是有一些滑翔能力的,多半是推一下滑一段。

另外无独有偶,在越战期间也有人这样干过,两架f4共4名飞行员参与,而且这回被推的机组获救生还了。http://www.af.mil/news/airman/1296/pardo.htm

家园 从上面的英文评论来看,这件事不可能是真的

But the measure of a heroic act lies not in success. It lies in the doing....

(这里第二个lie当“撒谎”讲)

很明显,AFA Magazine, John L. Frisbee, Contributing Editor (注意,能够有资格做Editor的, 都是行业内公认的专家)对这个说法非常不以为然。

家园 没事关引擎?找死吧。

通常引擎出毛病就得跳了

f86有空滑能力,不过朝鲜战争开始时,我很怀疑对空滑有多大的信赖,

再说高速中堆。。。。

啧啧,

自行车上你推我我推你我相信,

不过那摩托车你推推看看

家园 都不是英文母语的。

能从这判断吗?这两个lie显然是同样意思的。

家园 您理解错了

这句话应该翻译成“对于一个英雄行为的定义不在与其行为是否最终成功,而在于实施的行动”

家园 空中关引擎又不是什么不得了的事情

飞行员在训练的时候都有空中停车再开车的科目,飞这种科目的时候肯定都是人为关闭的了。

家园 记住那是什么时候,

朝鲜战争是什么时候?

那时候飞行员对喷气机空滑掌握多少?

f86出厂多长时间就上战场了

家园 那是什么时候

空中停车重启不管什么时候都是必修科目,没看过的话看看这里以前的文章,歼5飞行员都有这个科目了,别说是美国的王牌了。

家园 歼5是啥时候?

不用说歼5一直用到90年代,

歼5刚出来的时候,啥时候了?

另外,停产重启和空滑可不是一回事。

家园 不一样的,越战的这位是通过推动尾钩来推动受伤的飞机

仔细读了一下全文,就可以看出这位Pardo是在用他的座舱盖前缘来推动受伤飞机的尾钩...

The tailhook-used for carrier landings by the Navy's version of the now-venerable fighter is used by Air Force crews only for emergency landings. The hook snags a barrier cable stretched across the runway to keep the aircraft from veering or sliding. What Pardo was suggesting had never been done; the aircraft wasn't designed for such a maneuver.

Controlled by hydraulics, the tailhook lowered and locked into place, swaying in the slipstream of the F-4's twin J-75 engines.

Pardo pulled in behind and below Aman's crippled F-4 and slowly came forward, hoping to lodge the elusive tailhook against the leading edge of his windshield. Flying at 250 knots (about 300 miles an hour) the tailhook kissed the front of the windshield.

而且还要注意一点的是,越战时期的F4是两侧进气,就算是用机头顶对方的尾喷管,也不会造成什么损失;而朝鲜战争时期的F86可是机头进气的,你把涡喷发动机进气道一半面积遮起来他还能正常工作?

要还能正常工作的话那干嘛设计得那么大?减小到一半面积不更好么?

反正是打死都不信...

家园 麦帅信否?
