Official P51 and 109G10 oil leak tests

[-lynx-]

Still waiting for the answer how the damage was done to lose all oil to conduct the test and why it was decided that only lack of oil was the actual damage to the respective engines.

On the subject of inverted vs "normal" configuration I think inverted should be "combat safer". If the oil tank and pump are undamaged the oil would continue to be pumped into the heads/sprayed onto crankshaft lubricating it until the oil in the tank runs out. Loss of oil would be lower than that of a "normal engine" where a hole in the sump means loss of all oil in seconds... Same reason why damaged radials "live longer"?

Hmmm. If the DB605 was SOOOOOO good (<GGG> ) why wasn't it used after the war in racing? Hmmmm?   (obligatory tease)

How many factories built DB605 after the war?
or, how many wanted to buy german stuff?
also availability of merlin engine was far greater than DB605's.
well.. go compare the odds between brits and germans after '45  
Doesn't need much to figure outcome.

I think most of the engines use a remote oil tank, Lynx.

Generally, the oil is picked up at the bottom of the engine in a windage tray arrangement,runs through screens, dumped into a large tank, is picked up by the pump, is pushed through another screen or two, through an air cooler and then into the engine. That's pretty generic though, not specific.

Crank bearing clearances in air-cooled engines tend to be a bit looser than in liquid-cooled.

Don't know of any aircraft piston engines where running oil temp in the red isn't a serious problem to be fixed in short order.

Just food for thought.

What about the visual aspect? Hollywood is always showing the oil spurting all over the wind shield < - dunno correct term. What if when you got hit, your visibility slowly decreased as your canopy is covered in goo. Then it would not matter if your plane could stay in the air, if you could not see - you'd have to bail.. just more food for thought.

Note the P-38 in this picture, it portrays an oil leak that did not ignite, and followed out of the engine nacelle untill the engine siezed.

Due to the general design of most fighters in WWII, if the oil wasn't ignited it generally came out the sides and bottom of the nacelle or fuselage, that's not absolute by any means though. It did tend to coat the whole side of the plane, and in that P-38 shot, has actually been carried by the slip stream and stuck to the bottom of the horizontal stabilizer.

Looks like it's a problem with quite a few of the planes.  It'll be fixed in the next version.

P51 had 12.5 U.S. gallons and Corsair had 24 U.S. gallons.   I believe the 190 was around 18.
