how is it that a 190---D9 A8 F8 can take a oil hit and still fly around for 10 to 15 minutes before engine quits?
-
So can all P-47's... Hitech explained it a while ago - it's based on quantity of oil and rate of leak and when its depleted then coupled with how fast the engine heats up once the oil is all gone. It's not all fairydust, twin rainbows, and purple unicorns ya know... :D

They'll run for a while, the P47 will run a good long time. When I flew it habitually I took an oil leak as, "Time to head home after I kill the guy I'm engaged with." It was rarely a jeopardy situation. With the 190s I feel like if I expect to get home I better go now, or at least soon.

Air cooled radial engines. Not the D9 though. When oil cooled engines get hit they stop sooner.

Well you could say they're all oil cooled....if in doubt just disconnect the oil cooler and see how things go. :)

They may run for 15-20 minute (game time not r/l), but reduced performance would be a plus.

I notice the 109s that get oiled will quit before the 190s do.. Or is my sense of time out of sync with my old age?

Isn't the oil cooler air cooled? :D

It is when its all over the windshield.

Strange it didn't cool me down very much when oil was all over my RV wind screen.

Are you saying that the rate of the leak is/can be based on how bad a hit you got and not just the type/model of the plane?

All leaks (including pilot blood) are randomized somewhat. Different planes have different sized oil reservoirs as well, it seems.

I was doing camera for a skydive and climbed out ahead of the other jumpers. At the end of the struck I turned my head back toward the door to get the camera on the jumpers and notice the side of the airplane covered in oil. It was streaming back toward the door with little wavelets on the oil's surface. I remember thinking I was glad I was jumping instead of flying that one. :)

Well the OIL was cool! I'd be willing to bet that the oil pressure in the RV went way down, but the blood pressure in the PILOT went wayyyyyy up! :devil

This one flew for a while after the oil leak (caused by flak hit to engine).

How in God's name was he able to see well enough to land?
-
Well the Jug holds close to 30 gallons of oil. Takes a while for that to leak out.
-
Not the recommended method for an oil change :D
-
No, but may definitely facilitate a pants change.

I met this guy one day at the Pima Air Museum. He was holding this picture and told a fascinating story of the day it happened.

I am more concerned about radiator hits. You don't last long in any plane.

I always found the D9 quit very soon after taking a hit. If I hit the oil cooler and it is leaking oil I know if i follow it he is not going home because it will soon be deadstick.

:airplane: Didn't do that in my RV-6 but in another homebuilt I was flying a crank broke and it was puking oil out of the breather and oil filler what a mess. Yes the big fan up front that keeps a pilot cool stopped turning and it got hot very quick without that fan. :) Fortunately a airstrip was close enough to land in one piece. Was not so lucky another time a carburetor needle valve turned the engine quit. This time was in a plowed field upside down. :( Two forced landings in 50 years of flying I guess is not TOO bad.

I have had two engine out IRL, both times flying 2 stroke powered trikes.
1rst flight with my soon-to-be wife, she was sitting in the back enjoying the view.
She accidentally pulled the choke in-flight with her thigh. I did now know that of course...
Exciting moments ... when I lowered rpm and the engine just quit, restart did not work, wet spark plugs...
I managed to glide back to field and set it down in one piece.. yes, she flew with me again :D
Another time ignition cables short circuited, that time I was at 2k so I had no problems except with clearing the runway from other traffic in runway circuit in time.
The trike had a 1 to 8 glide factor, just a little bit better than a piano, so - some yelling on radio was required.
Last 15 year - flying 4-stroke VLA taildraggers I never had a hiccup, the closest I got was when the rotax 912 decided to disallow more than 5000 rpm in just after takeoff. (normally more than 6000 rpm)
I was fortunate that was alone in the plane so I could clear the trees and make a safe landing. Turned up to be a carburetor problem.

It’s been several years ago and I’ve slept several times since then. So, I don’t recall a lot of the details of his story. I do remember him saying forward visibility was completely blocked and it was tough seeing out the side even with the canopy open with the residual oil blowing past.
A short time after hearing his story, this same picture popped up on the web with no explanation of what happened. If I see him in the museum again, I’ll get more details and pass them along.
Unrelated to this, a friend who flys a P-47 in the USAF Heritage Flight program, had an engine failure at this year’s first Heritage Flight event in Laredo, Texas about a month ago. He said shortly after takeoff the engine started vibrating, with smoke and oil coming over the cockpit. Fortunately, he had sufficient altitude and airspeed to turn back to the field and land successfully before the engine completely failed. When he told me about this a couple of weeks ago, the owner was well into the process of R & R the engine.
