请熟悉肥电的xd进来看看这小玩意是啥？

传说中的冷却进气口?

我说是机轮舱的凸起，LZ你信么?

貌似骡马设计的非典是不带机枪的，需要的时候是外挂机枪吊舱的啊！表喷我！

把图片放大提亮以后可以清晰看见是个类似进气道的结构，左右两侧都有。。。不仅是个凸起

冷却进气口？为何不从进气道内引气？环控设备的冷却的话还可以用燃油液冷。。。还破坏隐身。。。

发动机舱冷却通风口。

你们两个在说啥？一个说机轮一个说机枪，不过LZ说的是那个缺口不是鼓包

原来天顶星也要开口进气冷却

怀疑是引流增加姿控喷嘴的推力，同时降低红外辐射

看，A型可不需要这玩意儿

这玩意儿也要整个S型进气口？

你贴的这是AA-1号机，是未减重之前的构型，这个进气口在背部：

新构型的F-35A同样有这个进气口：（图中为AF-1号机）

原文是在热交换器章节“Heat Exchangers
The X-35 had several external heat exchangers. A nose ram air inlet was incorporated for backup avionics cooling. A centerline heat exchanger provided cooling for the hydraulic system. A heat exchanger on the left side supported the environmental control system. The F-35 has two scoops located in the wing/fuselage to provide nacelle bay ventilation. The aircraft also has a scoop located on the top of the right wing-glove to provide air to the fuel/air heat exchanger. A deployable scoop is located on the left-aft fuselage to provide air to the IPP and to the avionics. The F-35 minimizes the need for external scoops by using heat exchangers that are integrated in the engine fan duct. These heat exchangers use engine bypass air as a heat sink.”
既然已经说用引擎旁路的空气冷却热交换器来最小化使用外部进气口。。。为何还要特殊为发动机舱搞俩通风口？不解。。。
难道135的散热很成问题？冷却气流量不够？还是为了减少发动机舱蒙皮的红外辐射？

看来F-35搞的真是很困难啊

F35这么多的小改动啊？

我也不知道为什么。

个人猜测，是F-35使用了DSI进气道，无法使用附面层空气来冷却；这两个小进气口，也确实比其他飞机的附面层进气量小一些。

嗯，这个推测有可能。。。飞机的综合设计还是很复杂的环环相扣，大部分东西都得妥协
