Real documentation on La-7 (Russian)

Recommended Posts

Reposting from Russian side, for those who are interested. Everything is in Russian, but you might get it translated. For the drawings alone, it is worth it.

 

- La-7 Technical description: https://disk.yandex.ru/d/0S8yV5teC71_fQ

- Armament: https://disk.yandex.ru/i/p0rz6vKaJ3VSUw

- Armament: https://disk.yandex.ru/i/pBAzYvYw78myIQ

- PBP-1 and PBP-1B + archival photos and photos of the sight: https://disk.yandex.ru/d/CNN09DP0ClO3uA

 

A basic explanation from Twister1:

The B-20S cannon has a lower muzzle velocity, due to the design feature (greater travel of moving parts than that of the ShVAK) and a slightly shorter length of the rifled part of the barrel.

PBP-1, 1A, 1B. Letters stand for the model of the sight. A is an improved or bis, B is a new model.

The PBP-1B is larger than the PBP-1 sight.

Comparison of optical data and dimensions in mm PBP-1B and PBP-1 in parentheses.

Focal length: 110 (60)

Lens Light Diameter: 50 (40)

Removal for Big Ring: 240 (195)

Small Ring Removal: 350 (290)

Height: 185 (160)

Width: 145 (100)

The sight was installed on La-5 aircraft from about 1943.

 

Especially the archival photos, are of fantastic quality, and really interesting to see IRL.

 

Thanks goes to @Twister26

 

Enjoy!

Hello,

First of all, thank you so much for sharing these documents, I've saved them and will try to OCR and translate once the DCS La-7 is out.

Just one detail, the two books I quited are actually on the same link ... the Technical Description seems to be missing. Hopefully you can fix the link.

Cheers,

 

Eduardo
