Hi

Just stumbled accross the drawings of the WWII german V2 rocket drawings designed by Wernher von Braun. Quite a nice job for 1942 and the basis for the US rocket program that followed

That's a bit late, Klaus. Seventy years ago and you could have made a
lot of money.

Now don't go off and build one of those in the garage, ya hear! :)

The remarkable thing about those is how big they are (there are parts in
the Science Museum in London), how many the Germans made in so short a
time and how much it cost.

[A bit thin on actual numbers there, but you get the picture.]

This link says they were 45ft long and cost 100,000 Reichsmark initially
and they pushed that down to 50,000 Reichsmark later.

https://en.wikipedia.org/wiki/V-2

Not sure if the 4.2 exchange rate still held at that time but it would
mean in the end one such rocket cost $12k. That's not really expensive.
But AFAIK they used slave labor for some of the production jobs. Anyhow,
I am glad this chapter of history is over.

Not likely, the U.S. government awarded several million $$$ to GE to reverse engineer the simpler V1 and they couldn't get to square one with it.

That's why the government then proceeded to pry lots of scientists out
of post-war Germany. The book "Operation Paperclip" is a very
interesting read.

Old draftsmanship was sometimes wonderful. It took a lot of skill and experience

to do that with, often, ink on vellum or starched linen.

indeed but it also took whole lot of people to clean up drawings doing
them in ink on that semi transparent paper so it could be copied
I actually took two semisters of engineering drawing, which nobody much liked

but was really valuable. Lots of kids nowadays know how to drive Autocad but not

how to draw. I still design with pencil on vellum.

I did too, early 90's was probably one of the last years it was required,
real draft tables with rulers on rails etc.

For quick sketch paper is fastest, but CAD where you can just type in
accurate numbers, do measurements, move things around is real nice

Considering how much more it cost to build a V2 than a bomber, and how
much smaller the eventual payload, the V2 program was probably a net win
for England.

I have heard of them. Have they gotten something into space by now?

not quite :)

About a month ago the had a successful launch of their first
active guided rocket, it reached 8250m and 1240km/h
I think that was with their hybrid LOX/polyuretane engine

And they have run static test with a LOX/alcohol engine

keeps amazing me how so many different airplanes, tanks, weapons,
etc. were designed and build in huge number during those ~5years

today designing and building even a single simple airplane would
probably take longer

Just create generic symbols that require only entering the name of a

subcircuit model...



http://www.analog-innovations.com/SED/SubcircuitImportByNetlist.pdf



Or, on a rainy evening, create a whole bank of generic symbols that

only need a model name entered...



http://www.analog-innovations.com/SED/SymbolSamples.pdf



PSpice has the advantage that ctrl-G (get part) displays a list of

parts AND a graphic view, so you know what you're getting.

that is fine for generic parts a like transistors, opamps ...
not so much when you need a special ic etc.
And drawing parts in PSpice is downright trivial.












Yup. Somewhere, in my travels, I saw a whiteboard that could take its

own photo.

we've had one that you just pushed a button and it scanned the board
and printed on A4

The other game changer has been the whiteboard and the digital camera.

I wish web conferencing services would understand that. I have yet to
see one with a nice interactive on-screen whiteboard where all
participants have drawing access all the time. With our start-up we use
GoToMeeting, they have a (way too crude) sketch set but only one person
at a time can use it and only the host can hand over presenter
privileges. I am usually the host but just the hand-over alone takes too
long.

Or is it just engineers who think that way and we are too small a market?

Yes, it seems that way. But a lot of resources was put into these war advances. The V2 project was actually bigger than the Manhatten project (Atomic bomb). A bomb is just a bomb (he he), the V2 was radio beam controlled, hadall sorts of control mechanisms including analog computers and doppler system for cut of control.

To do that in 1942 is amazing and it was huge

The US rocket program would not have happened the same way without the german scientists. It was even a V2 rocket that took the first picture of earthin orbit. The US quickly seized almost all the V2 rockets (and parts) and brought it to the states leaving the UK and Russia with the pieces

A lot of cool stuff. Radar probably changed the war, but in general war is good for if nothing else to push technology forward

As a Dane, I am embarrassed about the policy of the Danish government, turning the other cheek and only resisting when the war obviously would turn out for victory for the allied coalition. At least we had some good guys, Niels Bohr is one of them that was working on the Manhattan project as one of the top scientist.

yes it was a huge project, even with todays advanced tech available to
everyone as far as I know no amateurs (or very very few) have managed
to get a rocket into space that says something

but imagine being told: design a tank build a factory and make me 40,000
and then manage to do it in a few years

I think the Germans were working on an ICBM to hit the US. Might have

killed a few cows at best.

The V2 was intercontinental, they could have thrown it into a trajectory to hit North America if they wanted, according to Aberdeen.
 
Considering how much more it cost to build a V2 than a bomber, and how

much smaller the eventual payload, the V2 program was probably a net win

for England.

Back then bomber CEP sucked to high heaven, and radar controlled AA was coming into its own so V2 was a way way better.
