Mariner 10

[ryan]

I dont know if i should be doing this but oh well, March 29th 1974, Mariner 10 became the first man made machine to ever fly by the planet Mercury. Also in 1945 the V1 flying bomb made its final attacks on England, I think thats important to space exploration becasue without that V1 there would never have been a V2 and so on and so on. Stay tuned for more Ryans pointless space facts:lol:.
Thanks.
Ryan.

Ha.

 

[ryan]

Told you they were pointless, but thats me for you, pointless.
Thanks.

Actually, the V-1 is completely unrelated to the V-2. The "V-" designations are just political designations, the technical codes are actually "Fieseler Fi-103"and "A-4" (Aggregat 4).

But there was a V-2 test, which reached 90 km altitude on March 29.

But the V1 was a next big step in jet engine technolgy

 

[Urwumpe]

No, it wasn't. It was a pulse jet, which was pretty old school at that time (invented before 1900 in Sweden).

The engines of the Fi-103 had many limitations, which make them useless for jet fighter crafts: High fuel consumption, short lifetime (the valves only last for about 20-60 minutes)


The true step forward in jet engine development was the first axial flow jet engine, the Jumo 004 - before that, huge and less effective radial compressors had been used in jet engines.

The Jumo 004 got used in the Messerschmidt Me-262 ... and that is history...

My bad if i upsetted you to me it was big because my grandfather fought in world war two and captured a V1 and V2 test area and the feeling he got when he entered it was like he said it was hard to explain.

 

[Urwumpe]

ok, let's see...

I live...
...in a town where V-1 parts got produced in WW2.
...only 1.5 hours away from a former large underground factory for the V-2 (Dora Mittelbau)
...only 20 minutes away from a former Arado Ar-234 base - actually I served my military service there (some years ago, it was a mobile infantry base, now it's closed and a industrial park)
...only 2 hours away from the place where von Braun launched his first rockets.

Don't ask me about cold war history, I know somebody who served in a tactical nuclear missile unit during the cold war, but that's it.

Wow i would love to see all those sites. Also i would like to see the football games you have (soccer) you germans have weird stadium designs.

We have?

 

[Urwumpe]

We have?

I just got the same question in my mind. We have?

Let's make a direct comparison...

The Volkswagen-Arena in Wolfsburg (31,000 spectators) vs.

Robert F. Kennedy Stadium in Washington DC (56,000 visitors).


And which one do you call weird? :lol:

If you are interested in German technological history, visit Munich, the German Museum there is not only the largest technical and science museum in the world, but also has some exhibits which are pretty uncommon and comparable to the US X-Planes...

http://en.wikipedia.org/wiki/Deutsches_Museum

If you combine this visit with a visit of the Oktoberfest, you can at least tell you had been there (but I think any closely packed mass of humans looks the same).

And of course visit the Ludwig-Maximilian-University of Munich. The probe knows why. :beach:

 

[TSPenguin]

Let's make a direct comparison...

You might have started something dangerous here...
I'll start praying to the probe at once!

That kind of looks like a balloon.

Actually, they call it "inflatable raft"(Schlauchboot) in Munich.

It is important to know as trivia, that the color of the wall lights of this arena tell you, which team currently plays: Red for FC Bayern München, Blue for TSV 1980 München and white for the German national team. Each cell of the wall can have it's own color.

But I would not call it strange. Just look at the Stadium of Union Berlin, the famous "Old forestry"(Alte Försterei). They still have a human operator to change the digits of the score.

It represents the weridness of this sport, the weirdness of the referees.

 

[Urwumpe]

Its less weird as American Football.

 

[TSPenguin]

That kind of looks like a balloon.

In fact, each cell is an inflated baloon. So you only see what it really is. A very honest stadium!

Can you imagine the guy who inflats them for a job, talk about a job that you dont have time to breath.
