Having changed cylinders on the R-2800 and various R-3350 engines, all poppet valve types, I became curious on how you did so on the Bristols.
True the cylinder came off similarly to the poppet engin ...

The V-1710 suffered greatly from its original customer requirements. Airship engines did not demand great amounts of supercharging. The Air Corp's fascination with turbo-supercharging probably limited ...

One little noticed form of water injection was used on international variants of the DC-8. Since no APU was on the aircraft you would be stuck with no way of starting engines if no huffer (ground air ...

Crankcases, steel or aluminum (WAD vs P&W) didn't seem to fail. However, a mechanics view of the differences may be biased.
As mentioned, WAD steel crankcases used cap bolts on special conical wa ...

I inadvertently used VC-118 (Douglas DC-6) when I meant VC-121 (Lockheed L-749) in my preceding post.
Many of the Lockheed VC-121A Connies were named, example being Bataan for Gen Douglas McArthur. ...

This is a great find. From books and post here and other source Wright scimped on its engineering people. The Truman report pointed at Wright Aero as being a problem. Pratt outsouced its engine to car ...

Tom, the PBM-5 switched away from the Wright R-2600 to the P&W R-2800.
Probably didn't need them with the swirch.
I would imagine the Mars needed fans with early R-3350 now maskinf four US airc ...

Not to beat a dead horse but, if the Rotol numbers are correct, the installation of a cooling fan costs little weight or engine power. I grant this is a sales brochure. Some Bristol engines came with ...

I don't believe the USAAF retained any C-69's. At Lockheed in NY, we had a very weary L-049 come through flying for a non-sched airline. Its main landing gear doors looked peculiar. They had a piece o ...

Lacking the maintenance or overhaul manuals for the types makes getting numbers hard.
Having had to do whole engine (18 cyl)valve clearance checks, I shudder to think of doing it on a corncob. Messy ...

There were many R-1830 engine models with two-speed single stage superchargers. However, most C-47/R4D had single speed, single stage superchargers, typically the R-1830-92. The aircraft had no need t ...

Oil skates? Granted I had little contact with the big Wasp Major. It would appear that "oil skates" were a design feature beloved by them. Fortunately, they kept them inside the engine.

A little investigation shows the Direct Fuel Injection System on the R-4360-53 is the Bendix 100-28-A5. Other engines in the range of the -53 model in the P&W list show fuel injection but none wer ...

R-4360 Turbo-Supercharged vs Non-Turbo Problems
My opnly experience with this engine was during conversion of ex-UAL B.377 to then BOAC requirements. A tremendous effort for ALL the wiring looms were ...
