BMW 003 Jet Engine - How It Works - for He-162 Full Build Tamiya 1/48

Real man's BMW

Excellent Video & Build. Gr8 detail. I’m building one for my 1/48 He162A-2

Thanks for the video showing your wonderful build! Your included history also added interest. Additionally, it might help explain the reliability problems the Germans were having, by noting that, from 1940 on, Germany had an extreme shortage of the strategic elements aluminum, magnesium, chromium, nickel, manganese, cobalt, tungsten, molybdenum, silver, platinum, affecting everything from camera film quality to rapid wear, erosion and strength of all military equipment. The aviation industry especially relied on light, tough alloys, and had to repeatedly lower its material quality standards, seek alternatives, and yet remain competitive. This very adversely impacted turbojets, especially turbine blades, where lack of proper alloys caused blade fatigue and insufficient resistance to the required high operating temperatures. Some partially effective work-arounds were invented, such as flah- chroming of parts, and creating hollow turbine blades. But these measures only raised reliability levels from unacceptable to barely tolerable. BTW, this is a major reason why Germany could not incorporate turbo-supercharging on anything beyond small-scale production: inability to produce stainless steel in required quantities.

Excellent! Very realistic.

Great job, excellent results, instructive explanation. Vielen Danken.

Very nice! I appreciate your sharing your work with us. First rate!👍

Wonderful build! Your historical information and gentle voice are delightful to listen to!

Nicely done explanation! I particularly love the hand-drawing visualisation. But one critic from my side, please don't repeat the common misconception of the air being compressed by squeezing it into a confined space. It's not a piston engine. Axial and to a certain extend centrifugal compressors rather work by the diffusor-principle. A diffusor being the opposite of a nozzle reduces the airflow speed by extending the flow area. This causes the air molecules to reduces space in between them and hence to compress. This includes pressure,cdensoty and temperature increase as in all air (gas) compressors. I know in a cut view the axial compressors rather look like a nozzle, reducing space and volume. The clue is the are between the compressor rotor blades and ev n more so the stator vanes, which form a lot of small diffusors. The air intake of aircraft gas turbines also commonly form such a diffusor, as you show it in your drawing, too. The reason, it's providing a pre-compression of the high speed in-flowing air prior to enterung the compressor when the aircraft is in motion. Btw. the turbine section inverts all of it being principally a nozzle in function.

i was not expecting an explanation of how the actual engine works!, very interesting and nice addition,, even if my silly brain still didnt really understand it lol. 😄

Awesome work my friend keep up the good work

Another great video my man!

beautiful !!! can i ask what glue you use to glue lead wire to the plastic ? Many Thanks Shaun.

Very interesting, where do you get the pipes, wire and cables from?
