warship building, the armament of the ships and the staff of the 1st class battleships. The M=l:48 scale model in the permanent exhibition of the Transport Museum demonstrates the Victory in the condition as she was in the time of the battle of Trafalgar. The ship-body was prepared by applying the battening technology, similarly to the original one, and on the visible places of the board all small details of the original ship can be found. The copper plate covering of the bottom of the ship has been prepared from the material and by the technology as the original. Part III. Papers In Connection With Transport History And Methodology Attila Szabó: Rotary-wing Aircrafts Of Hungarian Construction. In the history of the aviation the majority of the imagined flights was done not by aircrafts like those of our days taking off by gaining speed and being heavier than the air, but by flying machines taking off vertically in some form. In the course of the nearly one century old history of the actually realized aerodynamic flight (1903, the Wright brothers) the rotary-wing aircrafts of really good use, the helicopters commenced to spred after approximately five decades. The word "helicopter" comes from the Greek and originates from Leonardo da Vinci. In his sketches can be found the technical representation of the first construction of this kind. The Author deals in his study mainly with those constructions, which come up to the definition of the classic helicopters, i.e. which are rotary-wing aircrafts driven by engine. During the history of development of the helicopters the first really successful construction (the Focke-Wulf FW-61) has been made by German designers in 1937, although it was not able to lift useful load apart of the pilot. After a short historical review the Author describes the bases of the aerodynamics of the helicopters and their development and demonstrates the Hungarian inventors' rotary-wing constructions or their other constructions able to take off vertically on different ways, right from Lajos Martin's "Floating wheel" which has been patented in 1893 - till the RAF-2000 autogiro completed in 1994. The last part of the study informs about the rotary-wing aircrafts being in service in Hungary. Sándor Bálint: The Bus Transport Of Sopron And Its Environs Between 1925 and 1950. The Author reviewed in our 11th year-book the history of the bus traffic of Győr and its environs between 1925 and 1950. During his further researches he revealed the history of development of the bus transport in Sopron and its environs and complemented it by bibliography and foot-notes disclosed in our present year-book. The theme, which commands interest is treated by the study by splitting it up into the following Subsections: Preliminaries; The first buses in Sopron; The GySEV (Györ-Sopron-Ebenfurt Railway) and the General Transport Ltd in Sopron; Bus transport in the second half of the 1930s; Motor vehicle transport during the war. Miklós Merczi: Underground Traffic In Budapest. In the first part of his study the Author reviews the historic preliminaries of the construction of the so called "Millennium underground railway" built as the first on the continent in 1896 and the interesting events concerning the construction and operation, following that he deals with the ideas of railway development in Budapest at the tum of the century, till the 2nd World War. The second part of the study deals with the urban rapid transport development works and in details with the construction of the east-west second metro line. Dr. László Eperjesi: Transport Policy Between The Two World Wars In Hungary, The Railway And The Motor Vehicle Transport. The Author discusses the evolution and the positive and negative results of the transport development history in Hungary and of the transport policy of the Horthy era. Demonstrated will be the competition between the state railways operating on a traditional, conservative way and the road traffic coming up all over Europe in this days, and furthermore the economic and political measures influencing the development and operation of these two, most important transport branches. During the decades following World War I the transport structure of the developed industrial countries changed radically. While the railway transport developed slower, the motorization, but first of all the motor 377
