Ernő Rubik -- Hungarian Aircraft Designer
« on: July 28, 2010, 08:00:50 pm »
Ernő Rubik (Rubik Ernő in Hungarian usage) designed 28 gliders and 5 powered aircraft before his death in 1997. Only a few remained unbuilt projects. The most dramatic was the Rubik R-21 1.5-tonne military assault glider project (below).

There is also mention of a 'Dupla Góbé' training glider. Does anyone know if this refers to the R-31 Dupla? Or is 'Dupla Góbé' perhaps the missing R-29 or R-30?

As will be seen, the Rubik designations R-01 and R-02 were applied later to designs done for MSrE.

A little trivia here: Mr. Rubik's son, who shared the same name, gave the world Rubik's Cube!

Thanks Hesham but there's some online confusion surrounding that drawing. This side view actually illustrates the Mosalyev SAM-23 designed to compete with the Kolesnikov-Tsybin KTs-20.

The drawing (by Dennis Punnett) appeared in 'The Rise and Demise of a Weapon' in Air Enthusiast, March 1972, p.130. Above it appeared a photo of the KTs-20 and a 3-view of the actual R-21.

A Hungarian 3-view drawing is attached to the first post. An R-21 model is also shown on the following Hungarian webpage along with 3-views and other images of various Rubik aircraft and projects.
