Design and development

The development began 1946 and was accomplished by the technical designers Jiři Bouzek, Ondřej Němec and František Vik. The design bears a superficial resemblance, viewed nose-on, to the German Siebel type Si-204 which, among other German aircraft like the Bf 109, were produced in Czechoslovakia while under German occupation. The prototype (registered OK-BCA) flew for the first time on 21 July 1947, 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 of Aero's pre-war numeration scheme, but a reference to the 4/5 seats in the aircraft.

Operational history

Ae-45 prototypes were widely advertised abroad. In August 1949 Jan Anderle won 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 an Italian Ae-45 flew 3000 kilometers from South America to Dakar across southern Atlantic (as the first Czechoslovak-built aircraft), in 1981 Jon Svensen flew Ae-45S from Europe to the USA.[1]

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 the Kócsag (Hungarian: "Egret").
