Engine Tutorial

@AramL OK

@FalconAero no

@AramL excuse my are you Chinese 請問你是中國人嗎

棒棒哒

@sujun 这种人才可不止他一个...很多地方随处可以见，向外佬问中文...

@charles007 是的，但仅英语和西班牙语 >>> <<<

@charles007 。。。。这国外网站你你问q群？

有交流群吗？谢谢

Good work !
But
I wanted to do it first . 😭

Amazing tutorial :)

@AnotherFireFox oh my , I always thought those things go with more than initial 2G. Thanks

@crowxe I mean max TWR, not initial TWR. Space Shuttle irl has something like 1.2 initial TWR and has 3 max.

@AnotherFireFox but 3G already means 3 TWR which is way higher than most well build SR2 rockets

Physically, higher TWR means higher efficiency to orbit, because of low gravity loss. However this is dV-wise thing, not fuel-efficiency thing. If you define efficiency by fuel consumption efficiency per thrust, Isp is the only scale.

If you wanna put any astronauts onborad, you wouldn't want to accelerate more than 4.0 - early rockets had something like 9G, but modern ones usually have 3G.

@crowxe I agree 1.10 is way too low but I did this part of the video a long time ago I forgot

This needs to go in a new section that I've been asking for, players notes and tips. Good one but the TWR vs. Efficiency is opposite to my finding , a 2.5 TWR was more fuel efficient than a 2 & 1.5 TWR rockets.
Proof : my last craft (3 identical rockets except for TWR and engines mass) running the same vizzy program
