WW2 Pratt and Whitney R-1830 aircraft engine cylinder head from RAF Burtonwood that was recovered from a local scrap yard.
The Pratt & Whitney R-1830 cylinder head is a cast aluminum component that is screwed and shrunk onto a forged steel cylinder barrel. It is a key part of the fourteen-cylinder, two-row, air-cooled radial engine that powered many iconic World War II aircraft.
Technical Description
The cylinder head is designed for efficient air cooling and features specific design elements to ensure durability and optimal performance.
Material: The heads are made of cast aluminum.
Assembly: The head is attached to a forged steel cylinder barrel via a screwed and shrunk joint.
Valvetrain: Each cylinder head has two overhead valves (one intake and one exhaust), actuated by pushrods and rocker arms.
Valve Seats: Aluminum bronze intake valve seats and steel exhaust seats are shrunk into the head.
Exhaust Ports: The exhaust ports contain shrunk-in stainless steel liners, which provide slip joints with the steel exhaust pipes.
Cooling: Pressure baffles are used to provide uniform cylinder cooling under all flight conditions.
Bore and Stroke: The engine's bore and stroke are both 5.5 inches (139.7 mm).
Pratt and Whitney powered the B-24 Liberator, C-47 Skytrain, Douglas DC-3, PBY Catalina, F4F Wildcat, and many others.

The Cylinder Head is made of cast aluminum with integral valve mechanism housings. Features include a photo showing an intake port on the right and an exhaust port on the left, with a shrunk-in stainless steel liner in the exhaust port. The intake features aluminum bronze valve seats, while the exhaust valve seats are made of steel. The engine also includes fail-safe redundancy for two spark plugs and pressure baffles for enhanced cooling.
Instead of traditional cast fins, Pratt & Whitney machined the fins directly from the solid metal of the cylinder head forging.
More surface area: This process created a greater surface area for cooling compared to cast fins, which was crucial for the high-performance engines of the era.
The Cylinder Head: Made of cast aluminum with integral valve mechanism housings. Features include intake and exhaust ports with a shrunk-in stainless steel liner in the exhaust port, aluminum bronze intake valve seats and steel exhaust valve seats, two spark plugs, and pressure baffles for cooling.
Numbers on the side of the cylinder valve casing are 11182B and A1113.
The inlet valve is on the left, and the exhaust valve is on the right.
The exhaust side of the cylinder gets hotter than the intake side, so it has more and larger fins to help dissipate heat.

Does Anyone Know What Aircraft This is From?
All I know about this is that it is from WW2 and is American . There is two small stamps on it one says 291 W and is in a circle , the other says 275 and that is also in a circle. Mike Davey (an 'Old' member from my previous website) says: "It's a flame damping exhaust. Looking at the mounting flange it doesn't look like it is off any kind of aero engine I know. It could be from an airfield vehicle?"
General Electric B.22 Exhaust
Driven Turbo Supercharger. ParagraphBodyStart
What is it from? This is from a Boeing B17 Flying Fortress. What does it do? It was essential in maintaining high altitude performance. The supercharger was driven by engine exhaust gases blowing a turbine bucket wheel to compress rarified air at high altitude and provide the engine carburetors with the necessary volume of air for efficient combustion. Where is this picture from? This one was taken in Malc's museum of military. (Malc is the owner of this website).

What is This - Any Ideas?
All we know is that it's manufactured by Bakewell Aircrafts Product company, Los Angeles. It has been painted a drab green colour and it only has one pipe outlet on it. There is also some numbers on it, we don't realy know what they mean either. Assembly number : 5073568-1 Other numbers : 4073961-1 , SET T 1571, C23, S56. There is also a circle that says : "GOT 12" on it. If anyone can tell us what this is then click on the 'Contact' button at the top of this page.
