ju 390造句

• Werrell later examined the available data regarding the Ju 390's range and concluded that although a great circle round trip from France to St . Johns, Newfoundland was possible, adding another for a round trip from St . Johns to Long Island made the flight " most unlikely ".
• The Amerika Bomber proposal first arrived in G鰎ing's offices at the RLM in the spring-1942 timeframe, with the Messerschmitt Me 264, Junkers Ju 390 ( itself based on the earlier Ju 290 ) and eventually the unfinalized nose-wheel gear design version of the Heinkel He 277 emerging as major competitors.
• Of these competing types mentioned by Dr . Heinkel  outside of the thirteen Bv 222 six-engined maritime patrol flying boats actually built  only three of the Me 264 design, and a verified pair of the Ju 390 aircraft were ever built, solely as flyable prototypes, and none of these aircraft saw any action against the Allies.
• They also assert that the Ju 390 V1 prototype was unlikely to have been capable of taking off with the fuel load necessary for a flight of such duration due to strength concerns over its modified structure; it would have required a takeoff weight of 65 tonnes ( 72 tons ), while the maximum takeoff weight during its trials had been 34 tonnes ( 38 tons ).
• The first prototype, the V1, ( bearing " Stammkennzeichen " code of GH + UK ), was modified from the Ju 90 V6 airframe ( Werknummer J4918, civil registration D-AOKD from July 1940 to April 1941, then to the Luftwaffe as KH + XC from April 1941 to April 1942, then returned to Junkers and used for Ju 390 V1 construction ).
• In 1943, the " Kriegsmarine " withdrew their interest in the Me 264 in favour of the existing Ju 290 and the planned Ju 390, with the Luftwaffe preferring the unbuilt Ta 400 and the Heinkel He 277 as " Amerika-Bomber " candidates in May 1943, based on their own performance estimates, stopping any further payment for development work to Messerschmitt AG concerning its trans-Atlantic bomber design.
• Their more advanced Ta 400 design, first proposed in October 1943 with a tricycle landing gear setup and meant to be powered with a half-dozen of the same engines as the 277 was meant to use, was joined by the Ju 390, a Junkers six-engined version of the developed version of their early-war Junkers Ju 90 airliner, the operational Junkers Ju 290 maritime patrol bomber, and also using six of the same BMW radials as the 277, with both the earlier four-engined A-8 variant of the Ju 290, and the Ju 390A-1 each meant to have a pair of the He 277's " Hecklafette " quad-gun tail turrets, but with one each in the planned tail position and in a new nose-mount version.
