Take a close look at the #Junkers #Jumo004B. Jet engine of the famous #Me262. The Junkers Jumo 004, was the world's first production turbojet engine in operational use, and the first successful axial compressor turbojet engine. Some 8,000 units were manufactured by Junkers in Dessau, Germany.
This clip was created in collaboration with road.art 452. It explained the design by a cutaway example of a Junkers Jumo 004B jet engine in WTS Koblenz. A number of examples of the Jumo 004 turbojet exist in aviation museums in North America, Europe and Australia specifically at the Smithsonian's National Air and Space Museum, the National Museum of the U.S. Air Force, at the New England Air Museum, Bradley International Airport, Windsor Locks, CT; and in Europe in such museums like the RAF Museum in the UK, and Munich's Deutsches Museum, Cut-away version in Wehrtechnische Studiensammlung, Koblenz and in Australia at the Australian National Aviation Museum, as well in preserved examples of the Me 262A jet fighters in several aviation museums. Cut-away version at the AFB Ysterplaat Museum, Cape Town South Africa.

Embry-Riddle had one of these. Back in the 1960's in Miami, they went to start it up and a construction worker was standing nearby with a bunch of nails in his flipped up shirt bottom. When it started, he was startled and let his shirt down and the nails flew into the engine, FOD'ing it out. They have it on display in Daytona Beach, and you can see the marks on the compressor blades where the nails actually hit.

@stevenborham1584 2 года назад
That's static thrust ratio. There's much more power being made by the time the aircraft is airborne. Given the 3.14:1 compression ratio that thrust isn't too bad. Modern compressors get as high as 25:1 compression ratios. All in all it was obviously considered competitive with the piston & prop jobs of the day that were limited by prop tip speeds and getting heavier all the time. Look at specs on the Jumo 222 or BMW 803 for comparison with the latest German aero piston engines of the time.

Starting fuel runs into air intake of Riedel starter. 2) pull starting handle, this switches on the ignition and starter of the Riedel. 3) The Riedel must start within 5 seconds, otherwise recommence operations. 4) Read revolutions on the inner scale of rev. Counter 5) At approximately 800 rpm press the button on throttle lever. This causes starter fuel to be injected and ignited by by means of sparkling plugs And so on but always watching the temperatures! Approximately all books referred this way but only stated to press starter without mentioning that it was an electric starter. This is one of the few that really mentioned to pull the handle.

@@BeardedBavarianBiker. The essential ingredient which the German jet programs lacked was high-temperature alloys. No ferrous alloy can withstand the temperatures in a jet turbine. The Germans did not have nickel, the main component (around 50%) of the Nimonic alloys used in the British jets - these are generally similar to Inconel (both are proprietary alloys). Note that this is the turbine, not the compressor. People who advocate for superiority of axial compressors, and the German WW2 jet programs overlook the facts - Whittle was aware at the very beginning of his program in 1935 that axial compressors would be the long-term solution, but they were as yet poorly understood, so he chose to use the well-understood centrifugal compressor. The fact that the German programs, with their huge funding, had terrible difficulty with flame-out and rapid throttle change among other problems supports his rationale. It should noted that well into the 1950s, the most powerful jet engines were directly derived from Whittle's centrifugal engines - the Russians used enlarged reverse-engineered COPIES of his engines in MiG fighters. Also, Whittle himself was involved in an axial-compressor jet project circa 1943-on, and that Armstrong and Pratt+Whittney also had jet programs during WW2 which were axial.

If the war had ended in 1941 everyone who pushed it was OK. As it was they had to do the impossible. Make a reliable axial engine using yet to be developed technology.

Whittle and RR were already working on axial compressors for some years, too. They didn't push it like Germany because axial compressor operation was still quite instable and airflow control (bleed valves, variable stators) not really developed for serial production, yet. Hence they went with radial compressors for production engines first.Germany was certainly more risk taking because of its war situation. In other directions like material technology Britain was leading. Both worlds merged after the war. Especially in the US where British tech. (provided in return for war support) and German tech. (captured knowledge, hardware and brains) came together. Here Whittle and von Ohain worked together and became friends.

When he began his first designs (in 1935), Whittle's company PowerJets Ltd had a minuscule budget and design team. The centrifugal compressor was well understood, so he used that to reduce the variables. Even at an early stage, he knew that in the long term, axial would be the better solution - but one had to get there. There were at least two jet engine projects in Britain during WW2 which were axial, one of them with Whittle involved. In the early '50s, the most powerful jet engines were based on Whittle designs - including Soviet ones!
@SAHBfan
@SAHBfan Год назад
The British had axials design too, which were test flown in the Gloster Meteor in 1943. The 5th prototype flew with both Metrovick F2 and the F3 axial engines. The British decided to go with the centrifugal design as they had similar reliability problems with the axial jet as the Germans. Early American jet engines were based on the British centrifugal and axial designs. None were based on the German. The idea that the British designed centrifugal engines and the Germans designed the axial is a myth.

Grande engenharia mesmo com falta de materiais e nas condições adversas na fabricação dos mesmos.Parabens.

The engine that started it all. Frank Whittle may have invented it but the germans perfected it

Frank Whittle did not invent the jet engine, the first successful demonstration of a jet aircraft engine was August 27th 1939 in Rostock Germany. Whittle was only the 4th person to successfully demonstrate a jet 2 years later.

Von Ohain invented the jet engine 2 years before Whittle.

@@WorivpuqloDMogh Hans von Ohain and Max Hahnn built the first turbojet engine in Gottingen Germany in 1934. We know from British evidence that Frank Whittle did not start actual work on jet engines until moving to Rugby in 1936. The first successful demonstration of a jet aircraft engine was by Hans von Ohain and Max Hahnn on August 27th, 1939 in Rostock Germany. Frank Whittle was only the 4th person to demonstrate a working jet aircraft engine in 1941.

To think it was 1st fighter engine and so advanced. Germans really knew how to engineer something. Too bad they sucked at the whole geopolitics racism thing

Indeed, it was the British that really had a lock on the whole geopolitical racism thing... British colonialism invented the _concentration camp_ , mass genocide and the biggest holocaust in recorded history.

немцы тупые неправильно мотор сделали. зачем они впихнули туда бензиновый мотор когда можно раскрутить вал сжатым воздухом с земли. а воздухе они всёравно запустить мотор безиновым не смогут. а конус зачем ? когда можно в валу сквозной тонель сделать и для охлаждения и не нужно конуса.

You don't know much about jet engines, do you? Pneumatic starter motors were not really common those days, and electric ones quite heavy and expensive for the power needed, hence a gasoline one. Besides, pretty much all Russian axial compressor engines are based on German designs. The turboprop still used on the Tu-95 was designed in big parts by captured Junkers engineers.
