TheAero 45was a twin piston-engined civil utilityaircraftproduced inCzechoslovakiaafterWorld War II.Aero Vodochodyproduced the aircraft in 1947–1951, after which theLet Kunovicerolled out these planes until 1961. In 1958 the Ae-45S became the first Czechoslovak plane to cross theAtlantic Ocean.[3]It was the first product of the nation's postwar aviation industry and proved a great success, with many of the 590 produced being exported.
Design and development
[edit]Development began 1946 and was accomplished by the technical designers Jiři Bouzek, Ondřej Němec and František Vik. The design bears a superficial resemblance, when viewed nose-on, to the much larger GermanSiebel Si 204which, among other German aircraft were produced in Czechoslovakia while under German occupation. The prototype (registered OK-BCA) flew for the first time on 21 July 1947 and the second, registered OK-CDA, one year later. Flight testing ran without incidents and the type was released for series production in 1948. The model number of "45" was not a continuation ofAero's pre-war numeration scheme, but a reference to the 4/5 seats in the aircraft.
Description
[edit]The Aero 45 had a sleek, teardrop-shapedfuselage,with a rounded, extensively-glazed nose affording excellent visibility. It had a low wing on which the enginenacelleswere mounted, and aconventional tail.The mainundercarriagewas retractable but the tailwheel was fixed.
Operational history
[edit]Ae-45 prototypes were widely advertised abroad. In August 1949Jan Anderlewon the Norton Griffiths Race in Great Britain (Ae-45 registration OK-DCL). They also set several international records. As a result, apart from Eastern Bloc countries, the plane was also bought by Italy and Switzerland. On 10–11 August 1958 Dr. Pier Paolo Brielli flew an Italian Ae-45 3000 kilometers from South America toDakaracross the southern Atlantic (as the first Czechoslovak-built aircraft). In 1981 Jon Svensen flew Ae-45S from Europe to the USA.[2]
This type was used in Czechoslovakia and was exported to the People's Republic of China, East Germany, France, Hungary, Italy, Poland, Romania, Soviet Union and Switzerland. Hungary was a major customer, where the aircraft was known as theKócsag(Hungarian:"Egret").
