Im März 1942 konnte es an einer Messerschmitt Bf 110 erstmals zu Flugtests eingesetzt werden. These sorts of engineering detail challenges for the 109-004-series of jet engine designs, formed the setbacks that were the principal factor delaying the Luftwaffe's introduction of the Me 262 into squadron service. Diese Uhrenserie huldigt mit Designhighlights diesem Forschungs- und Geschäftsfeld, mit dem sich Hugo Junkers erfolgreich seine Existenz aufbaute. Exemplare des Jumo 004 oder dessen Schnittmodelle sind heute unter anderem im Technikmuseum Hugo Junkers in Dessau, der Flugausstellung L.+P. The first flight test took place on March 15, 1942, when a 004A was carried aloft by a Messerschmitt Bf 110 to run up the engine in flight. The Junkers Jumo 004 was the world's first production turbojet engine in operational use, and the first successful axial compressor turbojet engine. The Jumo Fo3 and 204 were licensed to Napier & Son, who built a small number as the Napier Culverin just prior to the war. Dr. Bruno Bruckman's old assistant on the jet engine program, Dr. Österich, took over for him in Berlin, and selected the axial flow design, due to its smaller diameter;[1] it was 10 cm (3.9 in) less than the competing axial-flow BMW 003.[2]. Franz opted for a design that was at once conservative and revolutionary. Variants of the engine were produced in Eastern Europe in the years following the war. Von Februar 1944 bis März 1945 wurden 6010 Jumo-004-Aggregate der Serienversionen B1 und B2 hergestellt, von denen 4752 Stück zur Ablieferung kamen.Diese wurden vornehmlich für die Messerschmitt Me 262 sowie die Arado Ar 234 verwendet. Nevertheless, it made jet power for combat aircraft a reality for the first time. : LAH-1032-1 39,00 € DVD. A number of examples of the Jumo 004 turbojet exist in aviation museums and historical collections in North America, Europe and Australia, including; Engine Revolutions: The Autobiography of Max Bentele, National Museum of the United States Air Force, National Advisory Committee for Aeronautics, List of aircraft engines of Germany during World War II, "Summary of Debriefing of German pilot Hans Fey", "Junkers Jumo 004 B1 Turbojet Engine, Cutaway", "Deutsches Museum: Turbojet Jumo 004B, 1944", https://www.facebook.com/watch/?v=2312086125580004, "Design Analysis of Messerschmitt Me-262 Jet Fighter Part II—The Power Plant", First Attempt of the 21st Century to Start an Me 262A's Restored Jumo 004B jet engine with its Riedel 2-stroke APU Unit, https://en.wikipedia.org/w/index.php?title=Junkers_Jumo_004&oldid=992966543, Short description is different from Wikidata, Articles with unsourced statements from June 2012, Creative Commons Attribution-ShareAlike License. A total of 7916 Jumo 004B were built by Junkers Flugzeugwerke plus an unknown number of engines at Opel. Metropolitan-Vickers F.2. Erscheinungsjahre 1944/1945 (Deutsch) CD-ROM – 11. Von Februar 1944 bis März 1945 wurden 6010 Jumo-004-Aggregate der Serienversionen B1 und B2 hergestellt, von denen 4752 Stück zur Auslieferung kamen. [4] Jumo tried a variety of compressor blades, beginning with solid steel, later hollow sheet metal ones, welded on the taper, with their roots fitted over rhomboidal studs on the turbine wheel, to which they were pinned and brazed.[4]. Das Reichsluftfahrtministerium (RLM) zeigte jedoch kein Interesse an der neuen Technik, kein Vertreter des RLM erschien zu dieser Vorführung. The Jumo 204 (originally designated Jumo 4) was test flown in early 1929 installed in a Junkers G 24. Upgraded Jumo 004 copies were also built in the Soviet Union as the Klimov RD-10, where they powered the Yakovlev Yak-15 as well as many prototype jet fighters. The first two stages had 27 rotor blades and 38 in the rest. Von Februar 1944 bis März 1945 wurden 6010 Jumo-004-Aggregate der Serienversionen B1 und B2 hergestellt, von denen 4752 Stück zur Auslieferung kamen. Nach dem 1. The Jumo 004C had increased thrust, auxiliary fuel injection and afterburner. The Germans were known to use both specially-designed wire framed hemispherical cages and/or flat circular covers over the intakes to prevent ingestion of foreign matter into their aircraft jet engines' intakes while on the ground. They focussed on areas such as material defects, grain size and surface roughness. The 004D had passed testing and was ready to enter production in place of the 004B, when the war ended. Das von Norbert Riedel konstruierte Aggregat („Riedel-Anlasser“) mit 270 cm3 Hubraum leistete 7,7 kW (10,5 PS) bei einer Drehzahl von 7150 min−1 und wurde von den Victoria-Werken in Nürnberg hergestellt. Following World War II, Jumo 004s were built in small numbers in Malešice in Czechoslovakia, designated Avia Avia M-04, to power the Avia S-92 which was itself a copy of the Me 262. Das Gewicht des Jumo 004 B wurde gegenüber der A-Version um etwa 100 kg reduziert. Jumo 5 Engine of 1932 A major problem of the Jumo 204 was the engine size. [1] Diese wurden vornehmlich für die Messerschmitt Me 262 sowie die Arado Ar 234 verwendet. Jumo 004 A – Vorserienmodell, ausgestellt im Luftfahrt-Museum Laatzen-Hannover Jumo 004 A – links Teil des Verdichtergehäuses, dann einige Verdichterstufen, rechts Brennkammern Jumo 004 B Schnittmodell – Blau: Verbrennungs- und Kühlluft; Rot: Brennräume und Verbrennungsgase Das Junkers Jumo 004 war das erste serienreife Strahltriebwerk der Welt. Weltkrieg nahmen die Junkers-Werke 1923 den Bau von Flugmotoren auf, um den eigenen Bedarf für die von ihnen gebauten Verkehrsflugzeug zu decken.

Franz started his development team later that year, and the project was given the RLM designation 109-004 (the 109- prefix, assigned by the RLM was common to all reaction engine projects in WW II Germany, and was also used for German WW II rocket engine designs for manned aircraft). It was not until early 1944 that full production could finally begin. Das Junkers Jumo 004 war das erste serienreife Strahltriebwerk der Welt. Several improved series were designed until the end of the war. Most of the Reich Air Ministry (RLM) remained uninterested, but Helmut Schelp and Hans Mauch saw the potential of the concept and encouraged Germany's aero engine manufacturers to begin their own programmes of jet engine development. But Franz's Jumo 004, an axial turbojet that produced 1,980 pounds of thrust, was the first jet engine to enter mass production. Jumo 004 - RLM 109 Ersatzteilliste Jumo 109-004B1 Hinweise fur technische aussenstellen: Jumo 109.004 B1 Keep In Touch. Some 8,000 units were manufactured by Junkers in Germany late in World War II, powering the Messerschmitt Me 262 fighter and the Arado Ar 234 reconnaissance/bomber, along with prototypes, including the Horten Ho 229. The Junkers Jumo 004 was not the first turbojet invented, nor was the ME 262 the first aircraft to fly under jet power. (Data from: Kay, Turbojet: History and Development 1930–1960: Volume 1: Great Britain and Germany. Layout: A=axial flow compressor stages, C=can combustion chambers, T=turbine stages. It was also the first turbojet in the world with axial-flow compressors, afterburning, and a variable area exhaust nozzle. Diese Änderungen hatten einen Leistungsverlust zur Folge – das Jumo 004 A brachte noch 9,8 kN (1000 kp) Schub auf, während das 004 B als „sparstoffarmes“ Triebwerk nur noch über 8,7 kN (890 kp) Schub verfügte.
