A bit of a shot in the dark here, but I'm trying to find information for some elderly friends regarding their father, a William Wilkinson.

He worked for Shorts Aircraft in the 30s and 40s and served in the Army during the war. By their accounts, he was involved in the installation of the first radar set in an aircraft.

Initial internet search doesn't come up with anything concrete, so if anyone has any knowledge or links, that would be much appreciated.

The first AI set fitted to an aircraft was a Handley Page Heyford, initially just a receiver then a transmitter and receiver as well, but they needed long antennae. After that, the first practical set was fitted to an Anson.

The first airborne radar sets carried aloft (at least in Britain) were certainly not AI (Air Interception) sets, that did not come about till somewhat later. I believe it was in fact a form of ASV (Air to Surface Vessel) equipment which first became airborne in the late 1930s, from my hazy collections of the Robert Watson-Watt autobiography.

Other way about, the development of ASV was as a result of the early work carried out on AI, and discovering (by accident) it could detect ships. Development was faster and ASV came into service earlier.

It would seem odd, that if he worked for an aircraft manufacturer for a number of years and was involved in the installation of radar in aircraft, that he would have joined the army?
One would have presumed that working for an aircraft manufacturer ( I am assuming he was a technical person) would have been a reserved occupation.
Even more so that he was involved with radar, that would have been even more specialised and reserved.
Just my observation and perhaps one of the idiosyncrasies of the British at war.

Radar was used extensively by the Army for anti-aircraft work, so they will have needed experts as well. My father briefly worked on late model WW2 radar predictor systems, before disappearing to serve in the Far East. He said the combination of radar and plotter predictors was so good later on that even a constant weave was no good, it really had to be random. He also recalled the fitting of mechanical cut-offs to predictor systems, to avoid the systems plotting ahead of dive bombers and shelling their targets instead!

Indeed it was and not very effective at the start of the war.
I am merely assuming that has he had been at Shorts for some time, his attributes were better used where he was.
if he was at Shorts fitting radar, my guess is the ASV in Sunderlands, a number of which were equipped by the end of 1940.

If you are looking at First airborne radar in the UK, then you will find plenty of references, but the Germans were far ahead at the beginning of the war and had a huge advance until 1943-44 where things reversed. . They had the first radar units of radar equipped night fighters and 360deg azimuth small antennas radars on the ground already in 1939-40. But not much documentation in English unfortunately. History is always written by the ones that win the wars. ..

My thoughts as well. He's also reputed to have been involved in the rebuilding of the VW factory at Wolfsburg after the war.

Don't tell ORAC you thought that though, else you'll get the cut n paste treatment.

The first AI radar was fitted to the 604 Sqn Blenheims operating out of Manston. They were operational in the summer of 1940 and saw service in the Battle of Britain.

German radar was more technically advanced than Britain's. however, as most military historians will tell you, the outcome is rarely about who has the best kit. The Chain Home High and Low systems were basic, but as a component of an integrated air defence system, they became very useful tools, and this system was instrumental in the Luftwaffe's defeat. In comparison, the Germans never really organised their air defence to the same capability. They had reached a point where they were close with the Kammhuber line, but they were still relying on single control units controlling just one fighter. The concept of a plan position indicator never occurred to them and no-one in command ever really had an overall picture of the air battle.

Didn’t Goering one night try to take personal control with disastrous results ?

Yes, he was the guy in charge, but my friends are adamant that their father was involved, also with the rank of Major.

Probably worth remembering that information didn't flow as a freely in those days and there may even have been classified projects they were not privy to. One group of people working on what they perceived to be the first airborne radar set were probably quite unaware of another group doing the same around that time, or possibly even years earlier. Still, a good tale to tell the grand kids I suppose.

Hanbury Brown was plucked out of Imperial College to work with radar and went onto work on airborne sets. He was involved in the early Blenheim flights. I would post a link but I haven't posted enough.

He had been awarded a first at 19 and was a founder member of the University of London Air Squadron in 1935.

Not everyone, of course, had to be a theorist. Many would have been those already experienced in matters such as radio valves, cathode ray tubes for B-scopes and the PPIs, aerial design etc and could well have been moved from team to team and project to project as their particular abilities lay.

Not every artisans name ends up in th history books. None of those who actually built the first steam engine or parts for the first radar are remembered.

Sorry , a bit off topic, but I was of course talking purely about technology , not tactical or strategical use. which of course you are 100% correct. In 1939-40 the Germans were about 4-5 ahead of the Brits technologically wise, . Only after getting a magnetron from the French in 1940 capturing a Wurzburg in Bruneval in 1942 did the UK catch up, and it was the discovery of the "window" chaff jamming technique that stopped the German technological progression as both Hitler and Goering did not believe in Radar and transferred all scientist and funds involved into the V weapons.
On your last sentence, this is not entirely true, they had a few large control centers in bunkers very similar to the UK system but using different technique, light guns i projected on a glass wall instead of moving wooden mock ups on a table, but they had a central albeit regional command. .

The French did come up with a couple of ideas that did go into the second GEC produced Randell and Boot magnetron design. The use of Metal Oxide coatings on the Cathode and making the Cathode a Cylinder with a separate heater element inside it. The French research was however somewhat of a collaboration between Gutton in France and Megaw at GEC. The French research allowed the British Mangetrons to work at much higher power outputs and have a much longer running life than any magnetrons built anywhere else. Randell and Boot's contribution was making the Anode block the outer case of the valve, unlike most of the other mangetron designs which had the Anode cavities as metal plates mounted within a Glass tube (The Russians and Japanese had beaten Randell and Boot as regards this feat, but Knowledge of it was not known in the UK at the time that the first British experimental model was built and run in February 1940). The Metal block Anode with the Vacuum inside it was much easier to cool than any of the Hollmann designed Magnetrons in Germany or the stuff produced by Phillips in Holland.

" as I know them " is probably the answer As I said before , history is always written by those who win wars . What the French history books say , is that a Maurice Ponte was busy with early Radar technology since early 1930 , and had installed in 1935 a functioning prototype working on the Normandie ( the large passenger ship crossing the Atlantic between le Havre and New York) to detect icebergs and other ships at night and fog , and built by CSF ( now Thales). In 1940 when Germany invaded France, he fled to London in May 1940 with his centimeter wavelength magnetron prototype and gave it to the allied in order not to fall in the hands of the Germans, The US and the UK used it among other to reduce considerably the size of their antennas and systems and could catch up with the Germans. It was the basis of the mass produced SCR-584 radars built by the US and available in 1944 that helped end the war..

ATC_Watcher,

Thats covered in my link above, sections 2.4 and 2.5. The M-16 was a segmented magnetron, not a cavity magnetron.
