Pull Start

[hercrat]

The DC-3's I flew in the Arctic had to occasionally be started this way. I have done it twice, once with a rope and the other with a herc strap. THAT one flew off and hit the pick-up truck pulling it......but the engine started! Another trick was when the fuel pump wasn't working. To start the engine we sat on the cowling while the Captain turned it over. After about 4 revolutions you hand primed the intake with a cup of raw 100/130 and scooted off the wing before the engine caught. Necessity is the mother of invention!

Vlado,
What is winter ? I have not had to turn on the heat here this year, it will be in the low 80s this weekend. You and Moonbeam need to move out here where it is nice and warm and you can fly year around.

Oh, and as far as the turbocharger on the merlin, you forgot you took it off and used it for the compressor section of the T-33s engine.

Rimshot........good one!

I saw a Blackburn Beverley get started in up-country Aden in the 1960s during the emergency. Number one engine wouldn't start so a long length of hemp rope was found, and wound in the approved manner. A 3 ton truck provided the pull and with plenty of smoke the engine started. During the process there were worried faces looking out of the windows as the remote airstrip was frequently attacked and neither passengers nor crew fancied being stranded there.

Just thinking out loud ----

Wrapping a rope around the prop hub then pulling it with a truck has got to be inducing some side-loads on the front case and the engine mounts that may not have been considered during the desgin phase....

As long as a loading equivalent to or less than the polar moment of inertia of the prop is maintained, it should be OK. If it is in the manual, rest assured that the loads were evaluated and deemed acceptable.

...just ease off the clutch....and pray the rope doesn't get caught on the prop and pull you back in!

At a Temora airshow in 2006 the DC3 we were travelling in had a starter motor failure on the starboard engine.



It worked.

Dig that Holden Ute they have doin' the pullin'!

Cheers!

Hi Dean, not to split hairs but it was a Ford Falcon ute. It did snap the rope a few times on the edge of the tow bar but we got home.
FWIW speaking to some of the blokes involved there was a severe shortage of batteries down under during the war and this became a standard operating procedure.

I remember the rope thing for a -4 Corsair. IIRC, it had 3 or 4 leather 'gloves' that slipped over the prop tips as seen in the 3 bladed diagram. I saw it used with a pick-up truck once & a big ol' farm tractor once.

told me about how he rope started a merlin with an old tire a rope and a car....it could work although I sure wouldn't want to watch it.....
