Balsa Wood Bomber: De Havilland Mosquito

Not only balsa wood.

While the de Havilland Mosquito was famously constructed using balsa wood as a core material. It was sandwiched between sheets of birch plywood to create a light yet extremely strong composite structure. The use of this innovative wood-sandwich construction earned the Mosquito the nickname "The Wooden Wonder".

Key details about the Mosquito's wooden construction:
  • Composite material: The primary material for the fuselage and wings was a sandwich of Ecuadorian balsa wood between two layers of birch plywood. This produced a lightweight monocoque shell that was incredibly stiff and torsionally resistant.
  • Variety of woods: While balsa was crucial, other woods were used for reinforcing specific parts of the airframe, including spruce, ash, fir, and walnut.
  • Production challenges: When balsa became difficult to source in sufficient quantities during World War II, de Havilland sometimes had to switch to spruce for the core material.
  • Wartime innovation: The decision to use wood was a strategic one, as it avoided the use of aluminum and steel, which were critical and scarce wartime materials. It also allowed de Havilland to tap into the woodworking skills of furniture and piano makers for production.
Plus...

7.7mm Browning machine guns = .303 British cartridge. The Brits were using "Imperial Measurements" at the time.
 
I'll bet they sound fantastic...
There is an old video from in cockpit of one cruising about the English countryside. The Merlins were well synch'ed and could be heard moving in and out of phase in the video, which was quite long.
This one I photographed at the fateful Oct. 1988 show at Harlingen, TX. She is apparently no longer airworthy and is a static exhibit at the EAA Museum. Still belongs to Kermit Weeks, I believe.

I really like 12-cylinder engines. I've heard a P-38 with twin-Merlins. I wonder if the counter-rotating props sound much different.

Gotta repeat that I'm a sucker for P-51s
 
Well, duh. Thanks

That would probably make it sound different, ehh ?

Actually, P-51s had drifted into my brain when I typed that. My dad bailed out of a P-51 once and I started wondering which engine was in the plane he crashed.

But it was a stupid thing to not think b4...
 
The early P-51's (A model) had the Allison engine but not turbo-supercharged s the P-38 Allison's were, which muffled the engine noise. The Japanese called the P-38 the "Whistler Death" because they were so quiet.

The Brits figured out about fitting the Merlin into the P-51 and the rest was history with the "B" model being the first with the Merlin as standard equipment.

Both engines had their pluses & minuses.

The P-38 was there from beginning to end in WW2, while the P-38 really didn't show up until 1943.

Yep. Sorry. I had P-51s on the brain and I started thinking about the Allison-to-Merlin switch when I started wondering whether he had an Allison or a Merlin in the P-51 he crashed.

I think you meant to say that it was the P-51 that came into service mid-war And, like you said, the P-38 was operational at the beginning of the war.

And I apologize. Neither of them are Mosquitos
