Czech post-war jet fighter designs

Post by Petrus » 18 Aug 2004 18:35

After the WW2 Czechoslovakia tried to built an indigenous jet fighter. Reportedly the Czechs took advantage of the Me-262 design (a few airplanes of the type had been built in the country using parts left there by Germans) and wanted to marry the airframe with the British Nene jet engine. If I am not mistaken the aircraft was to be designated Letov L-52.

Does anybody here know more about this? Maybe there are some pictures and/or drawings showing the project? Any help would be really appreciated.

Best regards,
Petrus

I know of the Avia S-192, which is the Czech produced Me-262.


Sadly tho, I couldn't find anything on the internet through my methods... Maybe someone else might help you also.

Czesc Petrus, jak sie masz?
(Hello, how are you?)

It was Avia S92/CS92 (and not 912), first tested by Antonin Kraus in August 1946.

More about it:

Powodzenia!

And eventually I have found answers to questions I asked once here. In the issue 6/93 of the Czech magazine "Letectvi + Kosmonautika" there is an article about projects of jet-fighters that had been developed in the then Czechoslovakia just after the WW2.
As I can understand (being a Polishman doesn't mean I speak the Czech language), the most advanced project was known as the Letov L-52. It was to have wings, tail and landing gear very similar (if not identical) to that of the Me-262. Two versions were contemplated: single-seat fighter and two-seat trainer. The former was to be powered by the Rollce-Royce Nene II engine, the latter - by the RR Dewent V. Later it was decided that the trainer would have the Nene as well. A two-seat radar-equipped all-weather version was also planned.

The cocpit of the fighter was to be pressurised, armoured and fitted with an ejection seat whose design was 'inspired' by that of the type used in the Heinkel He-219 night fighter. Armament consisted of two German MK 103 30-mm or two MG 151 20-mm automatic cannon as well as unguided rockets of 210-mm and 55-mm. In ground attack role the plane would carry two 250-kg bombs.

Planned specifications were as follows:
Span: 12,50 m
Length: 12,00 m
Empty weight: 2214 kg
Take-off weight: 5670 kg
Max speed at sea level: 920 kph
Landing speed: 162 kph
Range: 1000 km

Development of the project (and its advanced version designated L-152) stopped after communists had seized power in Czechoslovakia in February 1948.

Best regards for now,
Piotr
