Re: Kharkov (Kharkiv) Aviation Institute "KhAI-" designations

[Silencer1]

In the book 'Aviation in Ukraine" (by V.Savin, 1995) there has been chapters, covering the projects and prototypes, developed in KhAI and other Ukrainian small design groups.
The table with specifications (on Russian) looks like this:


P.S. I prepared another version of table, with additional english text. Hopes, this helps

Absolutely brilliant. Thanks Silencer1! Can't wait to put this table to good use as I'm fascinated by these little-known Soviet/Russian student projects.

And thanks igor-mich for the great pics.

And also: VO-2M; S-1 to -10; S-100, S-102; TUNSO-2; T-10; U-2.

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:

• Nauchno-Tekhnicheskaya Biblioteka
• Istoria KhAI (bibliography)

This is only a list. Kharkov types and projects are pictured and detailed in several forum topics:

• Kharkov Aviation Institute (KhAI) "Aviavnito" projects
• Kharkov KhAI-2 early jet plane project
• Postwar Kharkov (Kharkiv) Aviation Institute (KhAI) aircraft and projects

The list has been further updated, with many new additions and a few corrections.
If you're interested in those university prototypes, make sure also to check the links given in post above; the topics, too, have just been updated with previously unseen aircraft and projects... with more to come!

Great, thank you Skyblazer!

Amazing work my dear Skyblazer,just seen.

Going over the KhAI list again, and adding/rectifying a few things along the way:

• The KhAI-1VV is sometimes found as just "KhAI-1V" (KhAI-1B is a mistake).
• The KhAI-2 (2) flying wing glider of 1934 was the same as the "P. Postyshev" glider.
• KhAI-3 has been found as an alternate designation for KhAI-1VV.
• KhAI-5 and R-10 were not exactly the same. The R-10 was the production version.
• KhAI-6 was also designated the SFR.
• Contrary to what I suggested, KhAI-9 was NOT related to the KhAI-Aviavnito-9. Instead, it was a glider designed and built by Isai Pavlovich Alexander in 1937.
• Contrary to what is said on some sites, the designations KhAI-12 and KhAI-14 were never assigned to sailplanes. This error results from a confusion by Westerners between "KhAI" (Kharkov Aviation Institute) and "KAI" (Kazan Aviation Institute).
• "Komsomolets-KhAI" was a glider built in 1953. Although it doesn't seem to have carried a designation, the date makes it a possible candidate for one of the undocumented -15 and -16 slots.
• A reuse of the designation KhAI-21 for a helicopter has been mentioned, but is not confirmed by any evidence so far.
• The first KhAI-25, an ekranoplane project, was never built, hence the reuse of the designation for a helicopter.
• The KhAI-28 (or BRO-DPK) was a development of the famous Oshkinis BrO-11 training glider from Latvia. Three were built for use by KhAI students. Note that an unspecified number of BrO-9 types had also previously been built at KhAI.
• Contrary to a frequent mistake (even found on a couple of KhAI-related pages!) the KhAI-32 had NOTHING to do with the much later Lilienthal Kh-32 "Bekas", just like the KhAI-34 had NOTHING to do with the Lilienthal Kh-34!
• The Grigorovich M-9 replica (KhAI-36) was built especially for a movie.
• Two more replicas were later built at KhAI: a Nieuport IV replica (for use in the Joker movie), and a Polikarpov Po-2 (U-2).
• An undesignated project was the "Salyut", a two-seater high-wing trainer study of 1982.
• According to a KhAI presentation, a single-seater delta-wing ultralight also carried the designation KhAI-40.
• The Vzlyot-KhAI Aviation Technical Club developed the KhAI-M01M5 "Khaiovets" project in the early 2000s. It was to be a four-seat high-wing multipurpose aircraft.
• The first unmanned vehicle developed at KhAI was the "Nosityel' Aerofotooborudovaniya" in 1973. Other UAVs were the NAFA-1 and NAFA-2 (1980) and the AN-BK-1 "Gorlitsa".
  The "S-" series consisted of delta-wing ultralight aircraft developed by the KAK A. Barannikov aviation club (part of SKB KhAI). The series ran from S-1 to S-9. The S-10 "Profil" was the only autogyro of the series. It was used for agricultural purposes, just like the S-7 and the S-5 SKh.
  The KAK A. Barannikov became the Deltaplanerniy Klub IKAR, developing only hang gliders: the "Student" series (Student-13, -16, -19 and -21) and "Stealth-KhAI" series (Stealth-KhAI-13 and -2-14). The Ukrainian government shut down the club in 2016, putting an end to its activities.
• Two proper aircraft were also developed under the "Aviaklub Ikar" monicker: the AI-10 "Ikar" (later produced by Skaethon as the K-10 "Swift") and the "Enei".
• The Shkurenko VS-3 "Sprint" apparently started life as a KhAI project.

I will soon upload a completely revised list.

 

[flateric]

UZGA LMS-901 "Baikal" apparently started life as KhAI projects.

?!

 

[Stargazer]

?!

I know it does sound strange, when said like that, but I found two clues pointing in that direction:

• mention of a "Baikal" in a list of KhAI-related projects,
• a post in a Russian forum on the day the LMS-901 flew, in which the poster said that he called his friends at KhAI to congratulate them. Second post in the page: https://www.forumavia.ru/t/201265/21/

 

[flateric]

Found it! Second post in the page:
https://www.forumavia.ru/t/201265/21/

Post author just saying that he called one of the UZGA staff that was studying with him in KhAI. Nothing more.
Baikal chief designer Dyomin has graduated MAI, was long time involved with OSKBES MAI and all the time MAI has some serious share in project tech side. So zero KhAI involvement especially considering timeline and political surroundings post-2014.
