Good video. As a passenger I too would be alarmed seeing the engine throw fire while starting up. Lycoming 320's don't do that as a rule.

Ah.... but Lycosaurs do not have over 2000 hp either ;-). Seriously though it is not considered as a big deal with big radials. Sometimes it just happens. Probably a good thing though that the exhaust ejectors have been plumbered to the trailing edge of the wing in that Convair....

I would shit in my pants if i were going to fly with that one...but what do i know, maybe thats a typical startup

[ovalila]

Almost typical Olle. Almost :-)

I'm from the jet days as a f/a so please forgive my ignorance when I ask this...I noticed some flame shoot out the back of the engine so I was wondering, is that normal? Great vid tho! :)

[ovalila]

Well..... not exactly "normal", but not unheard of either. As you can see from both mine and Charley's comments, the C-121 had stood for quite a while so it required a bit of a prime. While he was working on the starter and the primer, I was fumbling about with mags, mixture and a camcorder.... and I have only 2 hands :-) . So slightly overprimed but nothing really outraging except for some flames that were fast blown out by the propwash. Makes some nice vid material nevertheless.

Golden days... stupid jet engines...

@Roundmotor1 I understand there was NO difference between R2800 radial engines in the Convair 240 and the Martin 404. We had both landing at the airport when I was young. Eastern with the Martin and AA with the Convain. I also thought the engines were the same but the Martin's sounded louder with more of a drone and I think it was the short exhaust pipe verses the exhaust runnng to the back on the wing on the Convair. But the same engine none the less right?

@ovalila

The C-131 used the R 2800-103W the T-29 used the 99W

The exhaust flames during start up are no big deal. It is just hot unburned fuel hitting the oxygen in the atmosphere. The pilot will adjust the fuel mixture after the engine warms up.

Germans are not racists.The German state persecutes German people in the same way as foreigners.Torture and murder are seen as normal tools of the state because Germans get accustomed to this since beeing young children.So no German would ever complain.In no other country torture and murder by the state is accepted.Consequently foreigners being persecuted in Germany are complaining.This gives the completely false picture of Germans being racist.They are not.They are only NAZIs.See my homepage.

@ovalila they just do that, the fuel and oil that collects in the lower cylinders is the culprit , thats what makes the smoke and fire, nothing can compare in my view,jets are cool but round engines rule

[ovalila]

Close...very close. DC-6 engines were mostly R-2800-CB-16 whereas those in that C-131 Samaritan were R-2800-99W. Not much of a difference, mostly one is a civilian variant whereas -99W is military.

No backfire, so a good start. The fire just cleans out the accumulated oil

and grease, LoL....

[motorcopjoe]

So badass!!!

A flame-out on a North Central plane (Convair 580?) ready for take-off. Makes you just long for those olden days of U.S. commercial avaqition. Pass the ear-plugs please!
