Wenn Du hier schon auf den sehr geehrten Herr Expert Michael Elleman hinweist sollen wir ihm ja besser selbst ans Wort lassen, wie ich es getan habe in oben verlinktes. #1804Der Vorwurf, dass die Triebwerke der nordkoreanischen Raketen aus der Ukraine stammen, werden von anerkannten westlichen Experten erhoben und nicht von Russland. Sie beruhen auf Spektralanalyse der Raketenabgase und sollen eindeutig für einen Typ RD-250 (Klone?) sprechen.
"An unknown number of these engines were probably acquired though illicit channels operating in Russia and/or Ukraine."
"Rather, the technical skills needed to modify the existing RD-250 turbopump, or fashioning a new one capable of feeding propellant to a single chamber would reside with experts with a rich history of working with the RD-250. Such expertise is available at Russia’s Energomash concern and Ukraine’s KB Yuzhnoye. One has to conclude that the modified engines were made in those factories.
The alternative hypothesis, that Russian/Ukraine engineers were employed in North Korea is less likely, given the absence of any known production facility in North Korea for such engines. In addition, Western experts who visited KB Yuzhnoye Ukraine within the past year told the author that a single-chamber version was on display at a nearby university and that a local engineer boasted about producing it."
"Why single-chamber engines were transferred rather than the more powerful double-chamber original versions is unclear. One possible hypothesis is that the exporters, for whatever reason, exercised restraint in what they were willing to transfer to North Korea. Combined with a second stage, however, the single-chamber RD-250 engine is powerful enough to send an ICBM to cities on the American West Coast at least".
"The total number of RD-250 engines fabricated in Russia and Ukraine is not known. However, there are almost certainly hundreds, if not more, of spares stored at KB Yuzhnoye’s facilities and at warehouses in Russia where the Tsiklon-2 was used. Spares may also exist at one or more of Energomash’s many facilities spread across Russia. Because the RD-250 is no longer employed by operational missiles or launchers, facilities warehousing the obsolete LPEs are probably loosely guarded. A small team of disgruntled employees or underpaid guards at any one of the storage sites, and with access to the LPEs, could be enticed to steal a few dozen engines by one of the many illicit arms dealers, criminal networks, or transnational smugglers operating in the former Soviet Union. The engines (less than two metres tall and one metre wide) can be flown or, more likely, transported by train through Russia to North Korea."
"This is not to suggest that the Ukrainian government was involved, and not necessarily Yuzhnoye executives. Workers at Yuzhnoye facilities in Dnipropetrovsk and Pavlograd were likely the first ones to suffer the consequences of the economic misfortunes, leaving them susceptible to exploitation by unscrupulous traders, arms dealers and transnational criminals operating in Russia, Ukraine and elsewhere."
Wenn ich zitiertes vergleiche mit Ellemans eigen Satze bekomme ich Anfangsverdacht das hier deutlich gegen das land Ukraine gehetzt wurde im FF.
Elleman erwahnt wortlich: der Entwurf der modifizierte RD-250 konnt auch von Energomash Experten kommen, die Motoren selbst konnten auch aus Rusland kommen.
Dazu bei Elleman findet man keines solches Vorwurf, aber ich lasse mich ja gerne belehren, bestimmt haben andere Raketenexperten das so gemacht, bitte Quelle nachreichen hier.
