Lorenz 'Beam' Blind Landing System FuBl 2

We examine a working Lorenz "Beam" blind landing system - as well as explaining the system's function, we demonstrate a fully functioning restored example. The Lorenz FuBl 2 blind landing system was a military aircraft radio "beam" navigation system used from the late 1930s. The name is taken from the company that produced the system: Standard Elektrik Lorenz, and they referred to it as the Ultrakurzwellen-Landefunkfeuer, German for "ultra-short-wave landing radio beacon", or LFF.
In the run up to WWII Lorenz had supplied its blind-landing system to major airports in Germany and many airports worldwide.
In Britain, the RAF used the system until the mid-1950 refering to the system as "Standard Beam Approach".

This video was recorded at one of Europe's finest private collections of German avionics equipment, covering the early days of military radio communication and radar to the end of the vacuum tube era.

Presented by Dieter Beikirch with additional narration by Robert J Dalby.

Mr. Beikirch is amazing for explaining his amazing collection, and Thanks to this channel for making this kind of videos. Iam still fascinated how developed this systems was back then.

Thank you for the explanation of 1940s German aviation radio technology. After reading so many books of the WW 2 I became in admiration of those times in the development of all of that technology that allowed us some very good application in all fields of knowledge.

So this is how the localizer was born ❤

Can you do the Radieschen ultra-short wave passive homing radar? It was tested in the BV 246 glide bomb and it would have been one of the first anti radiation weapons.

Wonderful stuff... In conjuction with watching Mr. Beikirch's FuG 10 demo, does the Funker switch to FT + NFF, sets the FzF switch to LFF, and the Flugzeugfuehrer sets his remote headset switch to NFF? The FzF would hear both the left/right audio signal AND the VEZ/HEZ inner/outer sounds at the same time, correct? Does this also mean the intercom is not available to the crew when this is set? Or, perhaps I'm misinterpreting the FT + NFF versus FT +EiV switch on the Funker's station.

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?
