KÖZLEMÉNYEK - Winkler László: A magyar repülőtechnika 50 éve (1916–1966) (II. rész)

From 1938 the prosperity of war assures new financial possibilities for the Club (National Aviation Funds). So a new workshop and planning office are founded and types are produced in series (M-25, „Nebuló", EM-29). A special chapter deals with the activity of construction of Árpád Lampich and Béla Samu in Austria, where through them more Hungarian constructions were produced in series. As private initiatives of this period there are to be mentioned the experiments with helicopters effectuated by Oszkár Asboth, the type „Csikó" of Antal Bánhidi and his further plans, the types „Levente" and „Honvéd" of András Fábián. There begins a widespread construction work under the leadership of Professor László Varga in the Air Technical Institute of the József Nádor Technical University to assure Hungarian airplane production, starting from the light type („Szúnyog") of 40 HP till the combat planes of multitask (X/H) and the four-engine airliners. In this institute were developed, as one to the first in the world, the plans of a double-drive plane to the propeller-turbine, type Jendrassik CS-1 of 1000 HP. The planes of the Air Technical Institute were fabricated in the Air Experimental Workshop built on the airport of Ferihegy, where they were completely destroyed both ready and half-built during the air raids in the summer of 1944. The author tried to reconstruct by dates to be found the work mentioned and to awake interest for this material. In separate chapter are discussed the constructions of Ernő Rubik mechanical engineer, winner of the Kossuth and Paul Tissandier prizes and also the work of the aircraft factory he founded. The constructions of Rubik are nearly all built, and not few of them are fabricated in series of many hundreds. A special attention deserves among the plans of Rubik the metal constructions with Rubik-type surfaces in corrugated execution because of aerodynamical-statistical expediency. These made a perfectly new basis for building aeroplanes. Finally the publication summarizes the new Hungarian constructions developed since 1948, relating about the circumstances of realization and gives informations about the planes constructed on the field of helicopter experiments. This publication discusses Hungarian aeroplane construction plans until 1966 and the author — as he wrote it in the introduction — asks for the kindness of his readers in furnishing him the missing dates they may have at their disposal. 10* 147
