AEKKEA-Raab Designations

A discussion of AEKKEA-Raab projects has prompted me to chuck up a rough designation lists for AEKKEA.

-- https://www.secretprojects.co.uk/threads/aekkea-raab-aicrafts.11910/

Previously, I'd included designations for the earlier Dietrich* and Raab-Katzenstein designs. These have now been moved to their own topic pages (to match Stargazer's geographical indices). See:

_______________________________________

I've revised the above AEKKEA-Raab designition list slightly. The eBook Greek Vehicle & Machine Manufacturers 1800 to present: A Pictorial History by L.S. Skartsis has a section on AEKKEA-Raab but doesn't add to what is already available on Wikipedia. It does, however, have an artist's impression of the R-27 fighter (below, top).

This R-27 impression is acknowledged to be based on a well-known photograph of the Raab-Katzenstein RK-25 light aircraft (below, centre). Not to denigrate the efforts of whomever created this image but it really just depicts a single-seat RK-25 with a fighter-like cockpit canopy and tailwheel added.

So, I decided to have a go at a speculative impression of the R-27 myself. My speculative R-27 image began with the same RK-25 photo. I scaled a SPAD S.510 and added its HS.12Y engine. That dictated that the Raab's fuselage be deepened to match. The empennage was also enlarged - to cope with a seven-fold increase in horsepower.

I left the cockpit open. A canopy may well have been fitted to this 1935 design (and the canopy of the RK-25-32 would be a plausible reference for for its appearance) but I have no evidence for this. Still The speculative R-27's main undercarriage has been lengthened and I fitted spats (similar to those on the Schwalbe II, SX-AAL). However, I left the RK-25's tail skid (there being no evidence for a tailwheel on the R-27 that I am aware of).

Very good work! I like it very much.

Thank Wurger! Totally speculative, of course. But rather more plausible than that first effort, I hope

Hi,

does anyone hear about this Greece company before ?,it was mentioned in two old encyclopedias.

RAAB Flugzeugbau GmbH

Formed at Riga in 1934, but moved to Athens in 1935 as Societe Anonyme pour la Fabrication et I'Exploitation des Avions Raab.

Raab left the nazi Germany for Estonia , where he built Kl 1 at the "state aircraft fabric of Tallin" . Later , he founded the AEKKEA , subject of this thread , in Athen

Thank you my dear Richard.

Aviastar has confused the Gesellschaft and GmbH endings.

The 1934 Riga firm was the Raab-Flugzeugbau Gesellschaft - which built Grasmücke II; Tigerschwalbe II, III, and IV; and Anbo VI in the mid '30s. Flying Magazine, Feb 1936, pg 144

RAAB Flugzeugbau GmbH was formed in 1959 in Karlsruhe. One plan was to produce a modernized version of the RK 9 Grasmücke. Licences were also bought for Mario de Bernardi's MdB 2 Aeroscooter ultralight and the Ambrosini F.7 Rondone II. But RAAB Flugzeugbau GmbH got into financial trouble.

One RAAB-Ambrosini F.7 was completed (and sold), two more Rondone were structurally complete. One Aeroscooter was built and work was begun on components for another five.

RAAB Flugzeugbau GmbH was re-named German American Aircraft Corporation in 1959 but failed.

Many thanks to you my dear Apophenia,

and I know this company which formed in 1959,and later change its name to
Rheinische Luftfahrt Industrie (Rheinland).

Actually, Rheinische Luftfahrtindustrie GmbH was established in 1930. It had been Raab-Katzenstein Flugzeugwerke GmbH (which, itself, had been formed in 1925 at Kassel).
