By that time, problems with engine development had slowed production of the aircraft considerably.
One particularly acute problem arose with the lack of an alloy with a melting point high enough to endure the high temperatures involved, a problem that by the end of the war had not been adequately resolved.
His edict resulted in the development of (and concentration on) the Sturmvogel variant.
It is debatable to what extent Hitler's interference extended the delay in bringing the Schwalbe into operation; Albert Speer, then Minister of Armaments and War Production, in his memoirs claimed Hitler originally had blocked mass production of the Me 262, before agreeing in early 1944.
Armament production within Germany was focussed on more easily manufactured aircraft.
While German use of the aircraft ended with the close of World War II, a small number were operated by the Czechoslovak Air Force until 1951.
Test flights began on 18 April 1941, with the Me 262 V1 example, bearing its Stammkennzeichen radio code letters of PC UA, but since its intended BMW 003 turbojets were not ready for fitting, a conventional Junkers Jumo 210 engine was mounted in the V1 prototype's nose, driving a propeller, to test the Me 262 V1 airframe.
The V1 through V4 prototype airframes all possessed what would become an uncharacteristic feature for most later jet aircraft designs, a fully retracting conventional gear setup with a retracting tailwheel—indeed, the very first prospective German "jet fighter" airframe design ever flown, the Heinkel He 280, used a retractable tricycle landing gear from its beginnings, and flying on jet power alone as early as the end of March 1941.
The Allies countered its effectiveness in the air by attacking the aircraft on the ground and during takeoff and landing.Captured Me 262s were studied and flight tested by the major powers, and ultimately influenced the designs of post-war aircraft such as the North American F-86 Sabre and Boeing B-47 Stratojet.Several years before World War II, the Germans foresaw the great potential for aircraft that used the jet engine constructed by Hans Joachim Pabst von Ohain in 1936.Come share your work and learn about the diverse research going on in the CEE department in an event that is all about asking questions and making connections.
