Here's the expanded version of the KhAI- list. Some entries are still missing, some data too.
So please add to it if you can! And if you spot any mistake I will edit the list accordingly.

NOTE: Pre-war Kharkov types often appear under the name "Nyeman", after the institute's chief designer. The name was later removed when Nyeman was arrested in 1937.
Most of the new designations, but also the mysterious/unconfirmed ones are from online KhAI sources, notably these:
This is only a list. Kharkov types and projects are pictured and detailed in several forum topics:
