RMI -- Hungarian Aircraft Designations
« on: July 28, 2010, 08:27:24 pm »
RMI Aircraft Designations

RMI stood for Repülo Muszaki Intézet or Aviation Technical Institute. Aircraft were primarily (but not exclusively) designed for RMI by  László Varga. As a result, RMI designs are often given the Varga name (in some cases, even when he was not a major designer).

RMI-1 X/H (unflown recce bomber with turboprops (Jendrassik CS-1), designed by Laszlo Varga, Sóstó-built prototype was re-engined with WM DB605s in 1944 but destroyed before flying)

RMI-3 Z/G - divebomber trainer version of X/G, mixed construction, built '43, destroyed '44.

The Varga RMI-1 X/H illustration on Balaton-Modell is not correct for the re-engine version (with the DB605) because in the illustration the engine cowlings are for a radial, air-cooled engine, when the DB605 was a water-cooled V type engine. This would have had exhausts going in a row down each side of the engine, as in the photographs of the workshop.

Correct. The Balaton-Modell image appears to illustrate the  RMI-1 X/H prototype as originally fitted with the Jendrassik Cs-1 turbines.

Thank you, however, with the turbine shouldn't there be an exhaust at the rear? My understanding is that the Jendrassik Cs-1 turboprop had a rear exhaust similar in appearance to that of the Campini-Caproni CC.2 engine or the Junkers Jumo 004s and BMW003s. Is this not correct?

Quite right, and well spotted. Obviously that image was a botched attempt at representing the DB605 conversion  ???

I've eliminated that link.
