Hello, everybody! I was recalling that very famous footage of the Bf109Es scrambling just outside of a forest and the ground crews using what appeared to be hand cranks. Did all 109s use handcranks? This is a tad random but I know that my fellow flight sim nuts will put me to shame with their incredible knowledge. Thanks!

not sure about all the models, but in an article about a restored 109 G (I believe it was a G- the article was posted les than a week ago) the authored noted that the ground crew had to use a handcrank. If the Gustav still had a handcrank one might presume that the Emil and Frederik (?) did as well.

The crank was used to wind up the inertial starter.

I think they had an electrical starter as well but it was external (to save weight) and in real combat situations it was faster for the field personnel to crank manually.

question- by "handcranking" you mean start spinning the engine manually?

I think they cranked a flywheel, and the engaged it to the crankshaft when it was up to speed.

The hand crank was indeed for an inertial starter. There was no electric start.

well ..


given that you are looking at an turning over a 33.9 litre inverted V12 in the DB601 or a 35.7 lire V12 in the case of a Db605A (i think that works out somewhere around 2500 cubic inches) you sure want to hope it has an inertia starter

you sure aint gunna spin a 2500 cubic inch engine up t starting speed by grabbing the prop

Before a radial is started the prop must be pulled through by hand several times (to clear any oil collected in the lower cylinders). That is 2800ci for theR-2800.

Granted they are not started that way./i/smilies/16x16_smiley-wink.gif

Just for your information,

During the Pacific War, the RNZAF was loaned early 3 blade Corsairs.

Which did not have an electric start.

So a system of using about 8 guys and a 20ft strop was developed.

You can crank a 2800 by hand - it just ain't easy!

Virtually ALL German WW2 Aero-engines were started with a version of the Bosch designed Inertia-starter. This system uses a gear drive to spin a small flywheel at about 18,000 RPM! This causes the characteristic "howl" sound of this system. When the starter control is pulled by the pilot, the geared-down drive is engaged and turns the crankshaft at about 50RPM to start the engine. The 109 starter was ONLY a manually wound-up type because the ammo boxes left no room for the electrically wound-up version of the inertia-starter which was fitted to the 190 (more room for the electric version). Even the electric inertia starters had a manual drive for the groundcrew to use if the battery was flat, etc.

if u think the Me109 is hard to spin then u should see the one mounted on the stukas! It had a long crank handle that was placed vertically!!!
