My dear Apophenia,

there was also LAK 2,5,6,8,18 & 21.

 

[Apophenia]

hesham: The Lietuviškos Aviacinės Konstrukcijos (LAK for 'Lithuanian Aviation Construction') [1] applied numbers to its aircraft. Most won't have been designed by LAK but some may have been built by the club. The list of LAK numbers is:

LAK-1 == BK-7 'Lietuvai'
LAK-2 == BrO-11M 'Zylė'
LAK-3 == BrO-16 'Pempė'
LAK-4 == BK-7A 'Lietuva'
LAK-5 == 'Nemunas'
LAK-6 == Motorized 'Blanikas'
LAK-7 == Motorized 'Blanikas'
LAK-8 == Motorized 'Blanikas'
LAK-9 == 1976, no details
-LAK-9M = 'Lietuvą', 1977, no details
LAK-10 = 1977 revised LAK-9M
LAK-11 = ESAG 'Nida', LAK-5 replacement
LAK-12 = 'Lietuva', LAK-10 wing, new fuselage
- LAK-12E = Eksperimentinis, new 12 m wing
LAK-13 = [??]
LAK-14 = Strazdas, primary trainer, wooden 7.34 m wing
LAK-15 = Oct 1989, no details
LAK-16 = Strazdas, primary trainer, GRP wing
- LAK-16M = Metal-framed wing
LAK-17 = 'Nida', 15-18m span
- LAK-17A = 15 m span
- LAK-17B = 15 m span
- LAK-17T = Motor glider, 29 hp
LAK-18 = [??]
LAK-19 = Sailplane, 18 m span
- LAK-19T = Motor glider, 29 hp
LAK-20 - Sailplane 23m or 26m span
- LAK-20M = Motor glider (SOLO)
- LAK-20T = Motor glider (SOLO turbo)

[1] I had originally translated LAK as Lietuvos aeroklubas or the 'Lithuanian Aero Club. That organization did exist but, as Stargazer has pointed out to me, the aero club was not the makers of the LAK series airframes. (Thanks for that correction, Stéphane!)

 

[hesham]

A great list,many thanks my dear,

and I will search about LAK-18,I know I have it.

Hi,

here is an Anbo VIII in cutaway.

BRO-14 - 19??, [Project?]

The BRO-14 was a glider dating from 1961 specifically for picking up thermal currents built at the Simferopol Air Repair Workshop but remained in an unfinished state.

Source: Plieno Sparnai No 7 (2002)

 

[Cy-27]

The magazine Sparnai 1983 nr.1 had a feature on Oskinis work, filling in more details (may need the help of Google translate) about the elusive BRO-14, BRO-15 and BRO-19 types mentioned in the initial post by Apophenia.

 

[Apophenia]

Great stuff Cy-27! I just did Google Translate for the type role/description, date, span, wing area, and notes. I have assumed that "hodrosklandytuvas" is a typo for hidrosklandytuvas (hydro glider) but I'm not sure if this means 'Hydrofoil' or, more probably, 'Floats'.

(See Aubi's corrected list below)

 

[Aubi]

Slight changes: (statė means built, not state - lithuanian Google Translate was sadly "infected" with some english words)

BRO-14 -- Trainer, 1961, built by the designers in Simferopol and Kaunas

BRO-15 -- Motor-glider trainer, 1974, built by Prienai KSAG, unfinished

BRO-16 -- Float-glider trainer, 1973, built by the designers and glider pilots, Raguva & Prienai

BRO-17S - Experimental/educational, 1974, built by the designers and aircraft modelers, Palanga and Šilutė

BRO-17V - Float-glider trainer, built by the designers and aircraft modelers, Palanga

BRO-18 -- Experimental, 1975, built by the designers and glider pilots, Nida and Palanga

BRO-19 -- Motor-glider trainer on floats, built by the designers and aircraft modelers, Plungė and Telšiai

BRO-20 -- Educational, 1976, built by the designers and assistants, Palanga

BRO-21 -- Educational, 1978/80, first built by the designers and students of Kuibyshev Aviation Institute, second copy built b the designers in Palanga and Kaunas

To add to this thread, here is the 1937 BRonius Oškinis BrO-4 Ruta (Ruth) aerobatic glider LY-RUTA .

An interesting find - LY-RUTA still exists, well, sort of. There is a very well detailed model it along with a number of other types on display that give a visual for some of the designations that are listed in this thread:
