"Denyav" wrote in message ... The classic example was their nuclear research project. There was a period in late 44 when both Heisenberg and Diebner were running parallel programs and both required heavy water. There was only enough for one or the other but the German reaction was to give each a portion Diebner did not require any heavy water in late 44 Yes he did. His experimental reactor at Stadtilm was a heavy water moderated design and his job tiltles included Commissioner for Norwegian HeavyWater Production ,that the reason why he succeded He failed, the reactor never achieved criticallity, ironically however they did accidentally discover that they got greater neutron miltiplication amongst the graphite blocks sourrounding the reactor than with the uranium assembly in the reactor itself. At last in March 1945 they had stumbled on the fact that graphite could be used as a moderator, far too late to use that fact since US troops arrived only days later. And why British troops seized more than 10t heavy water in a warehouse in Hamburg. No such seizure was made and the maximum production during the war was around 140 kg per month You also forgat to mention Houtermans and von Ardenne. No their period of original work came after the war when they worked in the Soviet nuclear program. Actually the only German researcher who could have produced a bomb was Paul Harteck who attempted to develop the centrifuge enrichment process with virtually no official backing.

German fighter endurance was a sore spot, jet or piston-engined. I
remember seeing Guntar Rall on TV ruefully stating that the LW fighters had ninety minutes fuel whereas the Mustangs had eight hours worth. (At least he still had a sens of humor.) When the red light comes on you head for home or prepare to bail out. If Mustangs or Tbolts are camping over your home drome and you have ten minutes fuel left - gentlemen, that is a problem. So are the 1000 fighters the Allies could put in the air at once - a target-rich environment is not a good thing, especially if the targets are looking for you so they can another coup. Walt BJ |

I guess he means those 75 years aren't over yet...
Yup, 75 year period will expire in 2020. |

Houtermans and von Ardenne.
Not to mention that the German nuclear program was crippled severely by the lack of heavy water, thanks to sabotage efforts of Thor Heyerdahl (later famous for his Kon-Tiki raft showing the Egyptians could have sailed to the Americas) 1) In spite of Allied bombings and efforts or Norwegian resistance Germans transferred enough Heavy water to Germany over land route. 2)In summer of 44 Germans started to use graffit moderation and heavy water moderation was put to back burner. 3)They did not even need to use their heavy water stocks. |

Heyerdahl's chief radio operator (Knut Haugland) *was* part of the team
that parachuted into the German heavy water plant and blew it up. http://www.arrl.org/news/features Do you mean "ferryboat"?,plant itself was attacked by USAAF and RAF previously,which proved to the Germans that allies were fully aware of german intentions.(BTW Norwegian chief engineer of the plant was a British operative) |

Yes he did. His experimental reactor at Stadtilm was a
heavy water moderated design and his job tiltles included Commissioner for Norwegian HeavyWater Production He was the scientific leader of Heavy water production in Norway and according to his own testimony enough amounts of Heavy water arrived in Germany in Aug/Sep 44 from Norway. By the time the Heavy water from Norway arrived,it was no longer needed.He failed, the reactor never achieved criticallity, ironically however they did accidentally discover that they got greater neutron miltiplication amongst the graphite blocks sourrounding the reactor than with the uranium assembly in the reactor itself. At last in Marc 1945 they had stumbled on the fact that graphite could be used as a moderator, far too late to use that Strange,von Ardenne team reported as early as in Sep.42 that graphite could be used as moderator alternative!. No such seizure was made and the maximum production during the war was around 140 kg per month Yeah right,no such seizure ever made and also Saddam was about to build a nuclear arsenal,German scientists forgat in 1945 what they knew in 1941,NV Patrol boats attacked USS Maddox,Communists burned down Reichstag etc,etc. No their period of original work came after the war when they worked in the Soviet nuclear program. No they were two of three most important scientists of German nuclear effort. Guess what who has been ordered to built Soviet Bomb in Aug.45 by the Beria,A soviet scientists or von Ardenne?. (Obviously NKVD boss knew something about German bomb and its creators) von Ardenne,knowing that he could never see Germany again if he accepted Berias'offer and built a bomb for SU,diplomaticaly argued that soviet scientists not germans should have leading role (federfuehrung) in making of the soviet bomb,and germans should support them.That the reason why the soviet bomb was built under sobiet management. BTW ,Houtermans was a devoted Communist and anti-Nazi activist,he was in Soviet Union before WWII and was put into jail during Stalins cleansing campaign. When he (a German citizen) was arrested by Stalins henchmen,British gov't protested and requested his immediate release,British protest was accompanied by a threat of suspending commercial relations with SU. After British protest he was released and went back to Germany,or more precisely to Gestapo HQ. Have you any idea why British gov't acted so for a German citizen and communist jailed in Soviet Union?, Actually the only German researcher who could have produced a bomb was Paul Harteck who attempted to develop the centrifuge enrichment process with virtually no official backing. Surely Harteck is one of founders of centrifuge enrichment technology and his published studies are among thr best ,but in centrifuge technology Germany was decades ahead of the rest of the world,there were many talents in this field Zippe and Steenbeck for example. Might be a little bit subjective,but I consider Dr.Zippe as the most important contributor to centrifuge technology . |

Academician I.V. Kurchatov (Obviously NKVD boss knew something about German bomb and its creators) von Ardenne,knowing that he could never see Germany again if he accepted Berias'offer and built a bomb for SU,diplomaticaly argued that soviet scientists not germans should have leading role (federfuehrung) in making of the soviet bomb,and germans should support them.That the reason why the soviet bomb was built under sobiet management. Hardly, there were hired hands working on designs fed to them from Soviet agents at Los Alamos BTW ,Houtermans was a devoted Communist and anti-Nazi activist,he was in Soviet Union before WWII and was put into jail during Stalins cleansing campaign. When he (a German citizen) was arrested by Stalins henchmen,British gov't protested and requested his immediate release,British protest was accompanied by a threat of suspending commercial relations with SU. After British protest he was released and went back to Germany,or more precisely to Gestapo HQ. Have you any idea why British gov't acted so for a German citizen and communist jailed in Soviet Union?, This is fiction. Houtermans married physicist Charlotte Riefenstahl in August 1931, he left Germany in 1933 at the insistent request of Charlotte, and worked in Great Britain, near Cambridge. But in 1935, he agreed to a proposal of Alexander Weissberg, a Russian communist childhood friend, for an appointment at the Institute of Physics of Kharkhov, USSR His wife and their two small children managed to escape and get to the United States. In prison, Houtermans was tortured until he confessed to be a "trotskyist plotter" and a German spy, then he was imprisoned in Moscow. However, after the Hitler-Stalin pact of August 1939, he was handed over to Gestapo by NKVD and imprisoned in Berlin in May 1940. He was discharged in August 1940 thanks to Max von Laue, who found a job for him at the industrial lab of Manfred von Arden (in November 1940). Actually the only German researcher who could have produced a bomb was Paul Harteck who attempted to develop the centrifuge enrichment process with virtually no official backing. Surely Harteck is one of founders of centrifuge enrichment technology and his published studies are among thr best ,but in centrifuge technology Germany was decades ahead of the rest of the world,there were many talents in this field Zippe and Steenbeck for example. Might be a little bit subjective,but I consider Dr.Zippe as the most important contributor to centrifuge technology . Perhaps but their work was given no priority by the Nazis and failed to enrich more than a few grams of material. Keith |

Charles Gray wrote in message . ..
had actually put a U.S. style R&D system in place during WWII, and instead of coming up with (however pretty they look on paper) dozens of designs that never made it beyond wind tunnal designs and focused on say two or three fighter designs. For example, if they'd pushed through the first jet fighter design in 1940 (I forget what it was called), and focused on incremental improvmeents instead of always running to the next design. Would this have had a major impact on WWII, or just drawn it out by a few months? what if the British Air Ministry had listened to Frank Whittle's proposal for the jet engine when he presented it to them before 1932 |
