新燃料第一次真正试飞。说因为是旅游飞船,以前的燃料震动太厉害。
The hybrid rubber engine produced vibrations and oscillations so severe that
the ship would have been shaken apart if it had been burned anywhere near
full duration of about a minute. This is why on three previous test flights
the engine didn’t burn for more than 20 seconds. - See more at: |

https://www.ljsw.io/knowl/article/ld.html
过去十几年间,科学家用地面望远镜和太空探测器反反复复在大尺度上观测宇宙,发现
空间……并不是弯曲的。最新的一个结果是在2013年底由“重子振动分光镜勘测(
Baryon Oscillation Spectroscopic Survey,简称 BOSS)”发现、2014年1月宣布的
:在大尺度上,宇宙空间是“异乎寻常的平直(extraordinarily flat)”。
像这样超乎寻常的结论,科学家有超乎寻常的证据。弯曲空间中没有真正的“平行线”
—— 比如你在地球的赤道上画两条平行线,你会发现这两条线会在极地交叉到一起;
而如果空间曲率是负的,平行线之间的相互距离就会越来越远。但是科学家测量遥远星
系的光,发现并没有这种弯曲。
科学家还仔细考察了宇宙微波背景辐射的地图。如果空间是弯曲的,这个图就会有些弯
曲,如下图所示 ——
但是科学家观察不到任何弯曲。现在观测的结果,我们有误差小于1%的精度,认为宇宙
是平直的。
还有一个间接的办法。根据广义相对论,质量和能量可以让空间发生弯曲... 阅读全帖 |

Autogyros are often regarded by fixed-wing aircraft pilots as "dangerously
unstable", which is certainly true if one tries to fly an autogyro using
fixed-wing principles. Piloted properly, a autogyro is slightly safer than a
fixed-wing aircraft because it cannot stall. A "stall" does not mean an
engine-out event, it means a fixed wing aircraft is travelling too slowly
for the wings to produce lift. Since the rotor of a autogyro is always
spinning, it cannot stall... 阅读全帖 |

does engine rpm raise suddenly but no speed gain?
^^^^^^^^^^^^^^^this is normal.
there are small clearances between gears. during
gas release in low gears, your car can switch from
forword to backward suddenly to go pass the
clearance. it will create shock if gas release is not
smooth. :p
as oscilating, usually it is close to engine idle speed.
