Schwungkraftanlasser or Inertia Starter

Hello everybody! SkyLord Bob here!
In this video I present you one of the most important
parts on German airplanes engines
Schwungkraftanlasser or Inertia Starter.
Not for everybody.
Enjoy! :)

I'd sure like to see more about the gear train and how the device actually works. I saw one of these on a truck, and thought it was a massive additive gear train attached to a flywheel, but I guess not.

[@brianbaird6528]

Your original guess is correct. You turn the crank or run a small battery or generator -powered motor to get the flywheel spinning at a crazy RPM. Then you pull a handle (or engage an electrical solenoid to pull the handle) which connects the flywheel to the engine through gears, thus cranking the engine with the energy stored in the flywheel. This ability to gradually store lots of energy in a flywheel, then dump all the energy into starting the engine is what allows the use of very small batteries or no battery at all, which saves weight. A battery large enough to directly (not using inertia energy storage) crank a monster engine like was used on these planes would have been large and very heavy, likely over 200 pounds in those days. But a tiny lawn-mower battery would have been able to spin up an inertia starter enough to start the engine. If the war drags on and manufacturing of batteries becomes impossible, just hand crank the thing.

Finally I know what it looks like up close, thank you !

I'm glad that you like it! Thx for watching and comment. ;D

Tolles Video, gut erklärt, sehr informativ. Good Video, very good explanation of the starting-technique ,.....

[@skylordbob3237]

Thank You! Also thx for comment! :)

[@issur]

A good explanation and very suitable music, makes you feel one is looking back in time

[@skylordbob3237]

Thank you very much, Joseph! Also thx for watching and comment! ;D

[@fredbreuer5504]

Very well documented! I've always wanted to learn more about this amazing airplane engineering from that time ! Thank you very much :-)

[@basiltaylor8910]

It is perfectly feasible to energise the flywheel via the manual winding socket using an external electric motor a short shaft and overrun clutch with current supplied from batteries on a trolley. Such trollies were standard equipment at pre war US civil airports, relieving ground staff of the irksome job of winding up the flywheel. I can use a 1940,s Willy,s CJ3 Jeep to start a large radial aero engine ,i,e a Wright R-2600 Double Cyclone. On the back of the Jeep,s 3-speed Warner Gearbox is a power take off,like a tractor, . A shaft with a dog clutch runs from the PTO under the Jeep,s body to a strong flexible shaft attached to the PTO, the other is a hand held epycliyc angle drive gearbox with throw out clutch ,like a large Black&Decker electric drill. Once the R-2600 is primed ready to start . One mechanic sits in the Jeep it,s , 2.2 litre 'Go Devil' engine ticking over, hand brake on, foot on the clutch, selects neutral waits for a signal from the second engineer with the external starter gearbox coupled to the flywheel winding shaft nods his head to the jeep driver. He engages the PTO then feeds in the Jeep,s clutch and throttle. The Jeep is now driving the starter flywheel up to the required rpm . When the gear whine sound is right, two nods from the engineers head the pilot pulls the starter clutch as normal, the engine fires, Jeep driver dis engages the PTO as the second engineer disengages the external starter using the throw out clutch , he walks slowly backwards inline with the wing leading edge clear of the spinning propeller , jumps in the jeep to be driven clear as the aircraft is ready to taxy out for take off.

As the piston engines became larger and heavier, it was planned - and also tested - to start them with the F-type "Riedel" starter, a modified version of the S-type that was used for the ME 262 jets kzbin.info/www/bejne/bnLdqa2rZtikebc among others.

[@brianbaird6528]

I would like to find a source of inertia starters for small engines. It's a pain to keep batteries maintained for all the different machines I have that I only need to use 2 times a year. It would be nice to be able to just turn on the magneto, give it a crank for about a minute, and pull the handle. Might have to do it a couple of times, but that beats fighting with a dead battery all the time.

awesome video very well explained , thanks for sharing👍

[@christopherdansonxia9320]

Really good. Information dense and packed in a professional way. Nice

Such a great educational video!! Thank you so much

Very well made video, all most exactly what I was looking for.

Very cool video

[@skylordbob3237]

Wow first comment after over 60 views! Thank You Justin! It is very sad for me to see video in which I invested so much time and energy to end without any comment. Thx again m8! I really appreciate it! ;)

[@robbydolson2973]

They just sound so cool I could listen to them for hours.

[@normanfawley7379]

Just what I've always wanted to know ! Thank you.

[@TheSoundsOfFrank]

Skylord Bob ... GREAT video/explanation! Being a fan of the Bf 109E specifically, I had always wondered what the starting procedure was all about, and especially with the hand cranking/sound. An inertia starter! THANKS for an excellent explanation!

[@skylordbob3237]

I´m glad that you find this video useful. Thank You for watching and comment! ;D

i always had a question about this startes and that very peculiar sound they make , very nice video keep posting please

Thx! I´m glad that you liked the video! ;D

[@shaansingh2251]

thumbs up from me 2. I saw a yt video of a warbird starting up hence I was curious as to how it all works. thanks skylrd bob.

[@skylordbob3237]

Thank You Shaan for watching and comment! ;D

[@ooyginjardl4037]

I always thought that hand cranking loaded a spring motor which was spun up, then coupled to the engine via a clutch.

[@skylordbob3237]

Well acording to my knowledge the inertia starter was part of the DB 601 and other German aero engines from the beginning of the production. Maby only the first few series were without them , ergo they were manualy started via handle. Tnx for watching and comment! ;D

[@guntherpommer6433]

Finally the mistery has been cleared. Thanks a lot👏 What's the game called?

[@skylordbob3237]

The game is IL-2 Sturmovik : Battle of Stalingrad Great game. Tnx for comment ! ;D

Well some DB 601 engines have a classic starter, this one for example (and other Bf 109 Es on KZbin too): kzbin.info/www/bejne/hKPWlqmuZphqoMk

[@vladimirkalab5440]

that's because the owners made it that way, but wartime Es definitely didn't have these
