I'm trying to find cutaway drawings of the Grumman XP-50.

Draconis

I'm posting this message here because of the large number of WW2 aviation knowledgeable members here. I'm trying to find X-Ray or cutaway views/ drawings of the XP-50. That was Grumman's modified version of the XF5F redesigned for the Air Force. Mainly I want to see how and where exactly they fitted the turbochargers in those stubby engine nacelles.

So if anyone knows of a website featuring XP-50 cutaway drawings or could post an image from a book or magazine that would be great.

I'd not have high hopes on finding that.
Unfortunately, that is true for a lot of interesting aircraft - Fw-187, He-100, Ro.58 and whole host of Italian fighter prototypes, Curtiss SC fighter ( interesting due to the use of closely-coupled turbo with air-cooled turbine blades; an existing cutaway is very uninformative), Curtiss P-60 series, XB-28...

Yeah, that's what I thought. I've looked around on the net a fair bit. Even the 3-D drawings of the XP-50 lack detail.

Grumman using turbocharged Wright R-1820s in their XP-50 is not in itself a puzzle. They were used in B-17s by the thousands. What I'm puzzled by looking at the photographs of the XP-50 is where the stuck all the plumbing, the turbocharger and the intercooler. What I can see from what photographs I've found doesn't reveal much. Heck, I'm not sure where they stuck oil cooler. Good close-up photos of the engine nacelles from all angles would help.

One wonders whether a querry towards, nowadays, Northrop-Grumman would've been worth?

For the engine (and stuff) layout, might it be similar to the Grumman S2 Tracker? Same manufacturers, roughly similar size, some carryover on design principles ? Probably no drawings in the public domain for that one either, though
