wrongs:
1. Turboprops are only more common in commercial prop planes. "Most
propeller planes" are piston, as they are far cheaper to buy and run then a
turboprop.
2. Most (if not all) modern built fighter aircraft use turbofans. These are
called "Low Bypass Fans", usually with ratios bellow 0.5 : 1 (The F404,
engines on the FA-18, are 0.33 : 1 I think). Low bypass engines spin much

make the air intakes rather long. This was
an important consideration at design stage.
Second, they also needed to make
the air channel S-shaped, so as to hide
the fan blades from the radio waves emitted
by enemy radars. The latter is needed
for a lower visibility of the airplane. It

前置鸭翼，头部阻力增大，怎么超音速飞行？增加多少阻力？浪费多少航油？战机头上的铁帽子如何实现静稳定？歼20脑袋上订了个铁帽子压抑还说是机动？你脑袋上带个铁帽子机动给我看看？
愚蠢的骄傲狂徒和井底之蛙们给你们讲讲课，看完我的帖子，教给你怎么设计战机机长，翼展的比例，气动外形设计。真是废物，这么多年了，就靠仿制吃饭吗？拿个放大版的、双发大J10冒充四代机？你们的脑袋是干什么用的？连飞机长短都不会设计！！废物！
前置鸭翼的问题很多，前置鸭翼和全动垂尾是歼20最失败的设计，还有动力不足，全动垂尾，并没有给歼20提供足够的机动能力。歼20的设计师显然没弄明白垂尾和动力发动机的关系，垂尾和矢量喷气发动机之间的关系。歼20机翼的设计，估计设计师显然对音障不够了解。

最puzzling藕的还是空间和物质的可分性；
物质不断地分下去，是什么？
这个古老的问题，已经puzzling藕N年了。。。
这个不需要物理学知识，完全是个纯逻辑问题、纯哲学问题，或者说纯数学问提；
空间的可分性，也很paradoxical；
其它的比较简单了；

以太无处不在；建议研究以太动力学，ether dynamics；
以太很难被直接观测，但是，在weak interaction的时候，是以太造成了W＋，W－，Z

models have a habit of turning into working airplanes. And if that happens
in this case, watch out. Because it could potential give these Chinese the
