Die deutsche Avionik in der Ära der Vakuumröhre. Erforschen Sie mit uns die kritischste Periode in der rasanten Entwicklung der Elektronik, insbesondere der Bordelektronik, von den ersten Funkenstreckenradios im Ersten Weltkrieg bis zu den Fortschritten in der Radartechnologie im Zweiten Weltkrieg.
German avionics in the era of the vacuum tube. Join us as we investigate the most critical period in the rapid development of electronics, especially airborne electronics, from the first spark-gap radios of WW1 to the advances in radar technology in WW2.
This is fascinating. It's hard to get my head around the abundance of technology and innovation that the men and women on all sides had to deal with. I was born at the wrong time.
Sou fã dessa tecnologia dos anos 40 aos 50, fico impressionando o quanto que fizeram com tão poucos e tão limitados componentes, qualquer radio de bolso hoje tem circuitos com centenas de transístores, mas na Segunda Guerra havia radares com poucas dezenas de válvulas, eram aparelhos limitados mas mostravam uma imensa genialidade por conseguirem ser feitos com tão poucos componentes.
Fascinante, então pelo que percebi, São quatro traços na tela, cada um representando uma antena, duas antenas escaneam horizontalmente e duas verticalmente, o monitor vertical mostra os dois sinais das antenas verticais, um alvo a direita vai aparecer mais intenso do lado direito, o mesmo acontece no monitor horizontal.
its amazing that a full avionics unit of this guided system still survives. You can thank HS293 for the TOW, Dagon, Milan, Bullpup, Sagger, and many others after it. Its amazing that we really did not use this technology until around late in he Vietnam war.
i hope it all just not end up as a static display ,, or broken into parts this man have done such a impressive feat to have the items in working order,,
This is AWESOME..... a real gem of a video a guy who really knows his stuff , and the fact that these things still work ,,, i cant get over the sounds of these amazing relics,,,,
Like the way you sign off the channel name Deutsche Avionik in Morse code. I remember watching the BBC series secret war which featured RV Jones and the first episode was called battle of the beams. Many thanks for providing the details of the Y-Geräte system
Germany used to be state of the art in the electronics industry and competitive with the united states and the UK in this space and they kept up until the rise of the transistor.
Unlike Mr. Ramjet's "not that brilliant" comment, it was quite brilliant. Disguised as a normal instrument landing system (like our current ILS), the Brits ripped apart many crashed aircraft before an engineer noted that the radios were far more sensitive than they needed to be for bad weather landings. Captured German aircrews were interred in minimum security houses that were extensively wired with microphones and monitored 24/7 by native German speakers. The tipoff came when a pilot said "they'll never find it" and an astute British engineer realized they had probably been looking at the answer already.
R.V. Jones was aware of the system from Enigma decrypts and a captured document that a Luftwaffe Observer had on him so He knew it was on the aircraft. What wasn't known was the fact that radio waves at the required frequencies would "Bend" along the surface of the earth enough to allow the beam to reach targets in the middle of the UK from transmitters in Germany. Everybody in the UK thought they went out in straight lines and that a German bomber would have to fly at a very high altitude to use it. Once Jones had managed to get a senior British Radio expert from Marconi to admit that such a bending of a beam was possible and got the report about the two German crew talking about it, who were doing so because they had been interrogated about it!!! He asked the guys at Royal Aircraft Establishment if there was any difference between the UK blind approach systems and the ones found on the German Bombers. Jones knew exactly where it was hidden, because that was the only place it could have been hidden.
The 1936 vintage Junkers JU-52 that appears at 20:37 in the presentation has quite a history. It was owned for a time by the American aviation writer - Martin Caidin. Here's a link to "Iron Annie" (as she was called then): en.wikipedia.org/wiki/Junkers_Ju_52_WkNr_130714
I've been reading about spark transmitters (and building them from Model T Ford coils) for well over 60 years. I was stunned - and dazzled - to see the demo with a simple lighter and a homebuilt coherer. Bravo! Thank you both!
A fantastic exhibit Sir! How I wished we could take it outside and point it at the sky for a few hours... No idea how legal that is though is hehe :-) What is the feed-impedance of those shortened dipoles that the SN-2 uses? Regards, Thomas
The speed of the generator decreases when the morse transmission is made, that is, when it is under load. Doesn't this make a difference in the transmission tone? Would a scenario where the transmission tone is determined by the rotary discharger but the discharge occurs at the quenched gap be efficient? Is such a thing possible? It sounds like this way the tone can be kept constant.
hello.Enjoyed the presentationl. I am an old FAA ILS Tech in the US of A...can you tell us some about the German (was highly classified) bombing transmission beam system that allowed precision bombing of London?
Hi Larry. and thanks for your message. Take a look at our other vids. The following link will take you to a section that starts with X beams ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--6At9d99mt0.html. KR RJD DA
Everybody had it!!! The Beam Approach system designed by the Germans was first installed at an Airport in Berlin in 1932. A lot of people in Europe including the UK were using it before the start of the war. That is how the British discovered Knickebein, they had a standard Lorzen receiver and found that the ones fitted to captured Luftwaffe aircraft were much more sensitive. A Team in the USA had designed a better system which did do glideslope in 1930 before the Germans, but because it was so expensive, nobody bought it.
I turned on the SubTitles with English and its a terrible translation. It reads like scrambled english and comes out or results in something that is next to useless. The problem is the original german does not use regular language its using expressions that do not translate effectively into English. My guess is that its just as difficult to understand in German.
Wish i could try to add subtitles, but RU-vid somehow doesn't make it default for users to submit suggestions. It's definitely understandable in german, but the vocabulary may not be that easy for the automatic subtitles.
The design was not that brilliant, it used the 38-42 mhz blind landing beam and made it far more sensitive on the same short distance to get some required accuracy at long distance. Over a large distance, that tight beam expanded and the error range increased but it was still able to cause significant damage. The equipment was so obvious, the English knew the frequency of where to look and found it, which resulted in very effective counter measures. That blind landing system was a forerunner to the ILS system of today. What we don't ever see info on is the German Moving Map Display that was a forerunner of today's PFD or pilot Flying Display that enabled a 45 min flight around the traps and the display would fairly accurately show the aircraft's position relative to the airport.
Absolutely fantastic to see (and hear!) this in operation! I just discovered this channel and was surprised to hear mr. Dalby from the Astronomy and Nature TV channel, one of my other favorite channels. Great work!
