Amazing jet engine, the template for huge advances in aircraft propulsion

[@arminmoller9927]

Es ist unglaublich, wie modern das alles schon aussah.

[@randlerobbertson8792]

So near with this excellent engine. the single aft turbine wheel always surprises me though. Just think where theyd have got with access to quality raw materials, alloys and better quality manufacturing. Amazing technology for its time.

[@beholdpeople7554]

It’s very detailed for me 😮 the concept and design everything

Wunderbar gemacht...noch dazu ,weil hier im Nachbarort genau dieses Triebwerk produziert wurde und ich schon Teile davon finden durfte....

[@stelleratorsuprise8185]

Falls ihr mal eine neue Version mach, dann weißt unbedingt auf die Bedeutung des Stators im Verdichter und vor der Turbine hin. Ein paar Worte über das Diagramm zu Geschwindigkeit und Druck wären auch wichtig. Diese Details sind wichtig für alle, die glauben man könnte ein Turbojettriebwerk mit ein paar Blechscheiben in einer Coladose nachbauen, in den meisten schematischne Zeichnungen wird IMHO zu wenig erklärt und zu viel weggelassen. Danke.

Danke und du hast Recht! Das hier war auch nur ein eignes Projekt und dafür fehlt dann leider immer die Zeit...

[@samsignorelli]

Has there ever been attempt to build an authentic one with modern materials that actually had a lifespan?

[@paoloviti6156]

Yes, it has been restored some years ago an original Jumo 004 and actually they started it including a public demonstration. From the sound they had some problems and since then I never heard anything about it anymore. My opinion is that because it is possible that it was still fitted with original blades and other components it was developing far too many problems and possibly a serious breakdown but I'm only guessing....

[@samsignorelli]

@@paoloviti6156 I would actually like to see one from ground up with modern materials and manufacturing...just to see how long it would really last.

[@FiveCentsPlease]

@@samsignorelli The Flying Heritage and Combat Armor Museum has done exactly that, and had two Jumos researched and remanuactured over the last ten years. thumbs-prod.si-cdn.com/DYCCCTVzh5T0njQHrbPP9cmS02s=/fit-in/1072x0/public-media.si-cdn.com/filer/5d/12/5d120f6d-0216-4c10-aac6-e60996c0e7fa/06e_fm2018_engine_live_2.jpg Ground testing started in 2015 and now they are being installed onto the museums Me-262 restoration. Taxi testing will begin this year. This is the same museum that is building a Stuka to airworthy.

[@FiveCentsPlease]

@@paoloviti6156 There has been no public demonstration of the restored Jumo 004 engines. The internals are new metal because that was the point of working on them for over a decade and using modern materials. The museum only revealed the painted original Me-262 a few weeks ago. Taxi testing will begin over the Summer. pbs.twimg.com/media/D6JVRN1UcAATOUS.jpg

[@sandervanderkammen9230]

Why? The Jumo 004B engines were as reliable as most WW2 aircraft engines in this power output class and was more reliable than some post-war engines.

[@virtuellefabrik]

Danke! ich mach weiter! Da ich alle Videos selber erstelle, könnt ihr mich ja mal mit einer tollen Idee inspirieren? Ein Animation mit der man Menschen etwas zeigen kann, erklären kann, etwas schwer verständliches...aus der Physik oder oder oder... wird mich freuen, wenn Ihr hier ein paar Ideen hättet? Gruß Ronny

[@blubb92883]

so much cooler than 007 ;)

[@roteroktober360]

8,7kn ist sicher der maximale Schub, nicht der standschub, deshalb haben die Flugzeuge auch so langsam beschleunigt

[@virtuellefabrik]

Das wird der Start Schub sein. Als ich diese Animation erstellt habe war ich froh das ich das Video so hin bekommen hatte! Einige schreib Fehler sind dabei und auch der Verlauf von Geschwindigkeit Druck und Temperatur sind vereinfacht dargestellt. Wie gesagt ich war damals nicht unbedingt der Profi mit der 3d Software! 🙃 Deswegen hier auch die Verlinkung zu den Daten. Ich hoffe aber ihr könnt von den Fehlern ab sehen und die Animation gefällt euch trotzdem...? Gruß Ronny

Im Vergleich zu anderen Videos ist der Inhalt und die Verständlichkeit sehr schwach. Die Animation kann das bei weitem nicht ausgleichen, den so stark ist sie auch nicht. Natürlich steckt da viel Arbeit drin, aber ob sie es wert war, kann ich nicht nachvollziehen.

*There is a myth that the Germans were way ahead of the British in jet engines and planes in WW2, when the opposite is true.* The WW2 German jet engines were extremely unreliable with low performances with very high fuel consumption. The German *axial-flow* turbojets never worked properly being developed up to 1953 by the French to obtain a usable engine. The French lost a lot of time playing around with the German engines, instead of working with the British. The French and Soviets after WW2 attempted to improve the German axial-flow engines largely failing. The British in order to get a usable and reliable jet engine, with the technology of the time, went for a *centrifugal* design rather than the troublesome axial-flow design. This design produced less thrust than an axial-flow but was quicker to develop and reliable. It took 5 months to develop, while the first _reliable_ axial-flow engine was the 1950 Rolls Royce Avon, which took 5 years to get right - an engine still in use today. In 1945 the French made and tested some German designed turbo jets made with quality steel unavailable to German industry in WW2. They ran for 25 hours instead of 10 hours to the Germans engines that used poor quality steel. Not much better. The German axial-flow engines failed because of heavy design faults. The centrifugal compressor used by the first British Meteor plane was fine being much more reliable, but unable to reach high compression ratios. This limited performances. Centrifugal compressors were used up to the 1960s. In 1945 the team from the French ATAR laboratory plus some BMW and Junkers engineers, were engaged by the French SNECMA research bureau, with the objective to built a new reliable with performance axial-flow turbojet. The BMW 003/Jumo004 was considered unusable. It was tested on the first French jet aircraft, the 1946 So6000 Triton, overheating and exploding. The plane only flew with a Rolls Royce Nene centrifugal turbojet. The ATAR project took 6 years to produce the first acceptable axial-flow turbojet (ATAR 101 B1), produced in 1953. So eight years research & developments by the French using the German jet engines as the base. It was installed on the first French jet fighter, the Dassault Ouragan. The French lost a lot of time because the German jets had poor efficiency with some concept fails. Essentially in the combustion chambers and fresh air circulation to reduce the external temperature of the engine. The BMW jet was known for overheat problems which precluded fuselage installation. The question at the end of WW2 was what is the most efficient way to produce jet fighters. The answer is clearly not adopting the German design of engine and fuselage. The build costs for a jet engine were much higher than a piston engine, with the fuel consumption near 3x. The centrifugal compressor the British adopted in some planes was the best choice with 1944-45 technology, more compression pressure was not an advantage when the hot turbine was unable to resist higher temperatures. The German turbojets had big overheat problems as the engine would not work in an enclosed fuselage for single engined fighters. This defect was immediately noted by the French on the 1946 "SO 6000 Triton" prototype, and by the Soviets on the 1946 Mig 9. The Soviets quickly replaced the BMW 004B2 by the centrifugal Rolls Royce Nene which worked without problems, dismissing the BMW engine for fighter planes. The Rolls Royce Nene was copied to the last nut by the USSR being installed in the Mig 15 being used effectively in the Korean war. About 10 years ago the USSR eventually paid royalties to Rolls Royce. The Meteor was the first proper fully developed jet plane introduced. The 262 was slightly faster than the Meteor F3, but extremely unreliable. *The British would never put into the sky such an undeveloped plane as the me262.* The British could have had a jet fighter operational in 1941, but it would have been as bad as the me262. The Germans advanced R&D on jets after they interrogated captured British RAF men. They learned the British were advanced in jet technology actually flying prototype planes. Until then the Germans had no intention of mass producing jet planes. The rushed together Me262 started claiming kills on 26 July 1944, the Meteor claimed its first V1 kill a few days later on the 4 August 1944. *But the Meteor was a proper fully developed jet plane, not a thrown together desperate effort as the me262 was.* The me262 fuselage was similar to a piston plane with the pilot over the wings obscuring downward vision, while the Meteor was a proper new design fuselage specifically for jet fighters with a forward of the wings pilot position with superior vision, as we see today. The cockpit was very quiet. The sweptback wings of the me262 were to move the engines further back for better weight distribution, not for aerodynamic reasons as is thought the case. Centrifugal compressors were not obsolete being used in turboprops. Between a turbo jet and a turboprop, the only difference is the turbine, not the compressor. The last centrifugal compressor jet engine still in service on a handful of commercial aircraft like the Fokker 27, is the Rolls Royce Dart turboprop. A very reliable engine made in 27 versions, but with high fuel consumption to modern engines. The Rolls Royce Dart Turboprop turbo jet engine was produced the longest, being a comparable design turbojet to the likes the Rolls Royce Nene. The rugged engine was produced from 1946 up to 1987.
