The rotors stopped turning when the remaining engine was shut down, and the helo rolled on his side and began to sink.
They add a fourth rotor .
Then the sound of rotor blades rose above the din and the US military Blackhawk helicopter touched down in a plume of dust.
field in the rotor .
This is the Enigma rotor .
The left rotor isn't going to move anything.
So the rotor order is going to be 3, 1, 2 in my example.
Here's Rotor 1-- I mean 3.
And so the third rotor actually never moves in the entire message.
There were three rotors originally to scramble the German messages.
The innovation is these rotors that messes up the alphabet.
It advances the rotors mechanically, not electrically.
So every time this piece of the rotor gets up there, it has to have a north pole so it's repelled by the stator.
you change the magnetic field is the rotor .
You can eliminate a lot of rotor positions, because you can't have one letter coming back to the same letter.
And 250 wouldn't allow that third rotor to move.
Now they also have six rotors instead of two, which means Chopper can hold a lot, even carrying a scientific payload of its own.
degrees C uh I mean the the rotors literally glow um and uh I don't know there's a picture there that the car is
But only the right two rotors matter.
And then it goes through the three rotors , where it's changed.
Then they had to place the rotors in a particular configuration.
The other is that the rotors had a regular odometer motion to them.
And it had five other rotors to change the motion of those 10 rotors .
And this rectangle that you see in the middle is the rotor .
We're going to induce a magnetic field in the rotor , and we're going to have a rotating magnetic field in the stator.
So an A may be connected to a G in this rotor , but the A may be connected to a B in one of the others.
And here what we found out was that the rotor -based cipher machine was not invented by these four gentleman that I showed you earlier.
Then it goes through each of the three rotors .
So the way they used it with just five rotors , the way they used the plug board and so forth, what they saw
The next thing I have to do is put these rotors on a particular setting.
It adds a rotor .
And it turns out that the Enigma machine wasn't the only rotor -based cipher machine.
And what that does is it takes the signal from the leftmost rotor and it swaps it for another letter.
So what they had them do was they had them send a new rotor setting.
It's the rotors .
Because innovations are to add more rotors , to change the carrying capacity, make it bigger, make it smaller.
And here is a picture of the rotors .
And so this is the rotors .
So that gives you a sense for the key strength of just the rotors .
And the difference between the SIGABA and this is that it had 10 rotors to change the letters.
If there's a force up on the near side, you might expect the rotor to tilt immediately in this direction.
As we got closer, we saw a huge surge of rotor spray, and I knew instantly that they had landed in the water.
Machines can be added to, modified, another rotor can be put on the Enigma.
And they were always saying, we have to change the number of rotor settings on the Enigma machine, on every U-boat, every ship, every hour, every day.
As long as those two pairs of motors, the stator and the rotor , have different poles, that is to say a north pole-- or they have the same poles,
Now, what was unique about the Enigma machine and these other rotor -based cipher machines is the rotor itself.
So it does create quite a different algorithm, because that rotor will advance every time you push a key.
It tells you about how to oil it, how to sand the little rotor fingers, and what you need to do to keep it operational.
These seeds are still just falling, but if you add miniature electric rotors to the ends of each wingtip on this robot,
It goes through a reflector, reflecting back through the three rotors , back to the plug board.
