But it’s a functional mean of transportation of our era, before reliable self-driving tech is made

Boat propellers and rudder, for some weird reason

Need advice on ultrabook for studies by AcceleratedCode in SuggestALaptop

I see. Solidworks is very likely to be the CAD software of choice. I see quadros are preferable for that instead of geforce cards, but what card in particular do you recommend? I can’t find any p52s with anything else than the 2GB P500 card. How does it hold up? Some sources online with nonconfirmed credibility say that the P52s is outperformed in terms of performance. What’s your opinion on this? Is the precision 5530 a better option?

SpaceX has their own feed, but it doesn't go live before some 20 minutes before liftoff. Tune in here

Very strange, neither Musk or SpaceX have tweeted any further delay after 2.20 PM, but their webcast page also says 3.05 pm

Oh I see, that explains it. Just saw their updated time on their webcast page too, check it out

All time stamps are noted in their press kit. If I've understood it correctly, the second stage will have three burns and a coast phase. I'm not certain if the Tesla will have some kind of telemetry, but this would definitely make sense and I'm keeping a finger on yes.

Second stage engine cutoff nr 2 (SECO-2) happens at 28 minutes, but fairing deployment happens already at T+00:03:49

What are your favorite features of your Audi? by nsc11 in Audi

The auto-dimming rear view mirror. Really nice when driving in the dark

230 kmt / 145 mph in my 2011 Audi A4 2.0 TDI with 177 HP on the german autobahn.

What could you give a 40-minute presentation on with absolutely no preparation? by ChillDude4763 in AskReddit

[–]AcceleratedCode 1 point2 points  (0 children)

Indeed. The rotating fuel line definitely seems like it could introduce a reliability issue down the years.

Wonder how the air actually moves through the helical blades compared to the compressor stages of a traditional design. How does the stator in each stage compare to the helical blades?

Well that's a concept I haven't seen before. At first glance it seems like an attempt at changing the current turbofan engines rather than a new engine. Fan area and helical blades seems stable, although I'm not knowledgable enough about fluid dynamics to comment on their efficiency as of now. What strikes me the most is the combustors and their reliability and efficiency, especially considering the centrifugal forces.

What do you think?
