Trawling through my old backup CD's (!) from 2003 , I found spreadsheet for Boris Ivanovich Cheranovsky (Cheranovskii) designs that I thought might be of interest.

The base for this was, I seem to recall, from Bill Gunston's The Osprey Encyclopedia of Russian Aircraft and was supplemented by some articles in the Russian Aviation Research Bulletin and a book on Soviet gliders.
As the file data has been dormant for so long, it is inevitable that more data will have come to light in the intervening years and so any additions or corrections are welcome.

Where an entry reads "No details" I may have other notes on that type elsewhere, it's just a question of finding them!

I will split the detail into two or three posts....

In my source Bich-5 was a project of big military aircraft with two BMV-VI engines
Anyway, well done tovarishch Su-27)
 
Ucon

I suspect you are correct - it is unlikely a large, aerodynamically clean, flying wing aircraft would have the one powerplant!

Very great work my dear Cy-27,


but BICh-5 powered by two BMW VI engines,and not one,and retractable main wheels.


BICh-22 was also known as Che-22,a glider aircraft;
http://www.secretprojects.co.uk/forum/index.php/topic,467.0.html


BICh-23 was also known as Che-23,two seat glider;
http://www.secretprojects.co.uk/forum/index.php/topic,4731.msg159992.html#msg159992


BICh-26 a well known tailless jet fighter.
 
Very, very nice, Cy-27! Thanks for sharing this!

A few comments/additions:
  • I have the BICh-7 as the Parabola.
  • The BICh-11 was also designated RP-1.
  • Technically, the BICh-14's military designation should read TsKB-10, not CKB-10.
  • I have the #22 (which is missing in your list) as the Che-22, a flying wing glider.
  • I have the #23 (which is missing in your list) as the BICh-23, a flying wing glider.
  • I have the #26 (which is missing in your list) as the BICh-26, a flying wing jet type.
  • I also have an unknown BICh- jet design for which the BICh-23 may have been a demonstrator.
 
Thanks all for the comments and links.

Final bits and pieces before I look to revise with the various incoming notes.

It remains to find a picture or photo BICH-4 BICH-10
Click to expand...

According to Shavrov, BICh-10 was first version of what became BICh-14, and existed only in tunnel model form.
 
Still a bit of confusion, but I've tried to sort out a bit of the mess between this topic (Designation Systems thread) and the one in the Early Projects section, which can be found here:
http://www.secretprojects.co.uk/forum/index.php/topic,467.0

Please let's keep this here thread for listing the designations and discussing them, and place all specific data on one or several types in the other one!
