Author Topic: Jug Crash Site (Read 1546 times)

I did some Geo caching a few years ago in Hawaii to a supposed P-47 crash site, well that's what "they" said. Is there any way any of you can tell from what little was left of the engine is a PW-R-2800. Also, what is the part in the first pic? There was a piece of unpainted aluminum there, no markings though. Hard to tell if the paint weathered away or if it was truly unpainted. Sadly people have picked everything else away from the site. If you guys are ever in HI, its a good hike.

First pic looks to be a supercharger.

Or, more acurately, the turbine from the turbo-supercharger. The turbine was located towards the aft, ventral portion of the fuselage, below and behind the intercooler doors, with the turbine exhaust just in front of the tail wheel doors.

The engine is certainly a twin-row radial engine. You can see a small part of the exhaust manifold still attached to a cylinder head in the center bottom part of the engine picture. I believe that is the accesory housing that is on the right side of the engine. Don't know definitively its an R-2800, but it appears to be so.

The picture was more focused on the cache (plastic jug on top of the engine) and not the engine itself. Thats why the whole engine isn't in view.

Um. I live in Hawaii. By any chance is that in Manoa Valley? Ive heard of an aircraft wreck up the hill from my house, but its too nasty of a climb to go check out.

Its actually starts in moanalua valley. You go in that neighborhod and all the way at the end there is a playground. In the back is where the trail starts. It was one helluva hike...around 10 miles one way. That was mostly up 1ft wide pig trails with 100ft drops on either side. Pretty cool view into kaneohe from on top of the cliff, you are right above the tunnel. Not for the faint of heart.

What's shown in that first photo appears to be a supercharger turbine...not the turbocharger turbine that you're talking about. The supercharger is inside the engine case. I "think" the structure around what is shown in the photo is part of the engine case. I believe the turbocharge used on the Jug was basically the same one used on the B-17, B-24, P-38 and others. If so those blades are not the correct shape, they should be shorter and straighter.

The case looks like it could be a 2800.

Well sort of, as the supercharger casing is mounted on the rear of the engine casing.

Notice the impeller.

I wish, lol. Not old enough. I fly a Samba XXL light-sport/motorglider. It has an engine, cruises at 120 kts, but the FAA calls it a glider for some reason, so I can solo it even though im 15. I could jump in something heavier, a King Air or Cessna Caravan with an instructor (Dont know what the point of having him there is, he just talks on the phone the whole time...) but I think the Samba would be better for this. With full flaps, it stalls at around 20 kts, so I can get nice and slow following the trail. I posted a picture a LONG time ago, Ill see if I can dig another one up.

Nice, I have never seen one. Is that at Dillingham near Kaena Point? I did alot of offroading at Peacock Flats that overlooks Dillingham and used to get buzzed by the gliders alot...pretty neat, never knew they were coming until they were 10 above your head.

Serenity you're going to go fly around at low altitude looking for airplane parts and spotting trails to negotiate while next to a mountain?

Godspeed.

wooly15 · « **Reply #14 on:** January 30, 2008, 01:01:52 PM »

Haha didn't think of that Golfer! Serenity, it's in a heavily wooded area so you probably wont see the wreckage. Here is a map and some more pics to help you find it. Thats my ugly mug on the trail. Also a little better pic on the engine.

http://maps.google.com/maps?f=q&hl=en&q=Moanalua+Valley+Park,+United+States&sll=46.920255,151.083984&sspn=42.469841,82.265625&ie=UTF8&cd=1&geocode=0,21.373920,-157.880145&ll=21.395381,-157.843666&spn=0.113001,0.160675&t=k&z=13&om=0
On the map, "A" is moanolua valley park and you hike to where the tunnel exits the mountain. The wreckage is actually at the base of the cliff that overlooks H3
