Is that supposed to be "controlled rectifier" (like in SCR)? It was "crystal rectifier", and D was "dynamotor". You don't see many surface-mount dynamotors [1] any more, so lots of people have swiped D for diodes. These designators are the classic military ones. In the USA ! Of course in the USA. America has built most of the military electronics that have been used, since the start of WW-II. We can't leave a task like that to amateurs, and idiots. Actually, you simply copied many British designs. Actually, I didn't. The British designs were something they couldn't build, so why brag about being so incompetent? Radio, RADAR and electronics, in general was a new field, so lots of designs were worthless mental exercises withiout the knowledge to round off the rough edges and make the damn things work.? We had H2S up and running before America copied it and called it H2X. Our radars were working just fine - all we needed was US manufacturing capacity to meet the demands of the war effort. Designs you can't build are worthless. The brits didn't do a lot of development of microwave radar, aside from inventing the cavity magnetron. Most radar development was done at the MIT RadLab, assisted by US industry, inventing modern electronics in the process. Radar wasn't a unique invention. The US, Germany, and Japan were working on radar before the war, and all deployed radars of various quality during the war. The US radars were stunningly better than any others, for lots of reasons. Even during the war, we were using PPI radars that had ranges better than half the theoretical limits and stunning resolution. US ships sank enemy ships and subs that they never actually saw. The proximity fuze improved the effectiveness of antiaircraft guns and artillery by 1-2 orders of magnitude. Also in the post war years the US bought significant numbers of British jet engines because they couldn't get their own prototypes working properly. The German ones were better. John Having downloaded a huge quantity of aircraft e-books I'm not reading anywhere that the US imported German jet engines in the post war years, it was always British engines when the US couldn't get their own going - although TBF the US did go the honest route most of the time and build under license instead of outright ripping off the design like some other countries did. Right up to WW2 the US aviation industry was living in the dark ages - most manufacturers were still tarting up old biplane designs with enclosed canopies and retractable landing gear. When the US finally wised up and started making monoplanes they were struggling to get speed more than 250mph The P38 topped out at 443 MPH. 3300 mile range. With streamlined water cooled engines. |

writes Original Russian paper? They're only making their first stealth planes now. So what? The original Russian paper wasn't specifically about how to design or optimise a stealth 'plane but gave a method for predicting/modelling the radar return of a surface and, by extension, minimise it. It was 'discovered' by someone working for Lockheed in the 70s and used create a computer program that helped design the F-117A. And I'm still jealous of John Larkin having Skunkworks as a customer. -- Clint Sharp |
