Obsessed by flying machines, both atmospheric and in space. Check my favourites for some nice aircraft/spacecraft pictures.
It's called Delfly
Tu-95 was loud because the prop tips rotated faster than the speed of sound, creating a constant sonic boom. Other props rotate slower.
Props normally leave rotating air behind. This is a large energy loss. With counter-rotating props, this effect is cancelled, so more thrust
That's true. Taking off vertically, the weight is rather limited.
It is to keep the boundary layer (affected by friction from the skin) away from the intakes. This ensures smooth airflow to the engines.
Maybe, but on the other hand it's a good boost for the European aerospace industry. Countries like the UK will use both of them.
Thanks!
The French wanted air-to-ground capabilities from the start, plus they wanted to use them on aircraft carriers.
Sure, there's a lot to tell about that.
only 1-2 days flying and without communication delays. It'll give us a lot of insights in long endurance spaceflight before we go to Mars.
Excellent post! I personally believe we should aim for a moon base, since the moon is fairly unknown to us. Also it's handy that it's 1/2
This would make for some nice posters
They are quite small, and placed a lot lower than the main wing, so their influence is very limited.
I read that it was mostly the exhaust hitting the prop.
The noise they make is amazing!
Yeah, they really went crazy designing the Starship. Looks fabulous.
I think it's used for fuel tanks, air conditioning and similar stuff.
I think that's to reduce noise and to make it more efficient.
Nice post! Looks like something a kid would draw, those are always the best designs.
That's really cool! I never expected this to go beyond Imgur!
Amazing! Never expected this!
They would fold inside the fuselage when speed increased.
They already sold options to their planes. It shows airlines are really interested and willing to invest in it.
Turbojets use less air at higher speeds to make thrust. It's more efficient to have a high jet velocity when you're flying fast yourself.
It's because of shock waves, they cause a lot of drag near Mach 1, at higher speeds this becomes slightly less.
Nice work! :)
Certainly, only problem is getting enough air for the engines, since rockets are really inefficient.
I'd love to see them become reality. Bridges the gap between turboprops and turbojets nicely.
