Czech LF-aircraft

[Maveric]

Hi all,

we all know the great sailplanes LF.107 "Lunak" and LF.109 "Pionyr". Can you tell me the team or the firm, who designed this aircraft? Rudy Letov?

Thanks

This from 'Sailplanes 1945-1965', Martin Simons, Eqip, 2002
(volume 2 of the 'sailplanes' trilogy...)

"It (the LF-107 Lunak) originated in a project of
Vladimir Stros who in 1943 was working at
the Letov factory in Prague. Because of wartime
conditions and the confused political situation
afterwards, construction did not begin until 1947...
After 70 were completed, however, the factory was
ordered to cease production in order to make way
for the jet fighter, MiG-15..."

HTH,

cheers,
Robin.

...so the L.F.-designations fill the gaps in the Letov L-100-line?
Like the L.101 at http://www.secretprojects.co.uk/forum/index.php/topic,9448.0.html
or others at http://www.secretprojects.co.uk/forum/index.php/topic,5788.0.html

Do you know the meaning of the L.F.? (Letov F...)

Thanks robunos

There's no meaning in the designation LF other than L - cathegory aviation, F - sixth design team. It was designation used from 1947 to early 50s for design team led by Vladimír Štros. This group originated in Rudý Letov factory (renamed in 1947 to Letecké závody, n.p., závod Letňany - "Aviation Factories National Enterprise, division Letňany", then LET - Letecké závody n.p., závod 4 Letňany - "LET - Aviation Factories National Enterprise, division 4 Letňany" and then shortly back to Rudý Letov). In 1949 they were relocated to nearby Aero factory, at the time known as LET - Letecké závody n.p., závod 3 Vysočany. This factory, division of the same enterprise, became in 1953 direct subsidiary of Rudý Letov.

Because this isn't confusing enough, while the LF group sat in Vysočany, prototype of Pionýr (and presumably others) was built in Letňany factory, three pre-series machines in Vysočany and series production ran in Let (sic!) n.p. in Moravian town of Kunovice. From 1954, series production moved to nearby Avia n.p., závod Choceň.

In early 1950s both glider design groups, LF and LG (based in Otrokovice in the závod 7 of LET, later závod 02 of Let n.p.) were dissolved and no other specialised glider design group emerged.

As for the numbers, yes, it seems to be continuation of Letov line.
