Hungarian Pioneers

• The Hungarian aviation was born at Rákosmezo,
  Budapest.
• The first successful flights of Hungarian
  designed aircraft were flown by Adorjan at end
  of 1909 and in January of 1910.
• During I. World War, 5 000 workers produced
  aircraft in 3 factories on the land now belongs
  to Hungary.
• In 1912, Aladár Zsélyi and Tibor Melczer
  designed the aircraft 34 seats with engines of
  500 hps that was called by them Aerobus (!).

Introduction

• The Hungarian aeronautics was born together with
  the world aviation
• It was completely destroyed after World Wars.
• After 1956 the aeronautical training was fully
  destroyed, too.
• Since late 70s the higher education system
  slowly has
• been reestablished.
• The department of Aircraft and Ships at the BUTE
  is the only university level research and
  training centre of the Hungarian civil
  aviation
• The Department is active in most of fields of
  aeronautics.
• It has developed wide international cooperation
  and
• has joined the European research networks.
