Aero Ae-45 Explained

The Aero 45 was a twin piston-engined civil utility aircraft produced in Czechoslovakia after World War II. Aero Vodochody produced the aircraft in 1947–1951, after which the Let Kunovice rolled out these planes until 1961. In 1958 the Ae-45S became the first Czechoslovak plane to cross the Atlantic Ocean.[1] 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

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 German Siebel Si 204 which, 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 of Aero's pre-war numeration scheme, but a reference to the 4/5 seats in the aircraft.

Description

The Aero 45 had a sleek, teardrop-shaped fuselage, with a rounded, extensively-glazed nose affording excellent visibility. It had a low wing on which the engine nacelles were mounted, and a conventional tail. The main undercarriage was retractable but the tailwheel was fixed.

Operational history

Ae-45 prototypes were widely advertised abroad. In August 1949 Jan Anderle won 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 to Dakar across the southern Atlantic (as the first Czechoslovak-built aircraft). In 1981 Jon Svensen flew Ae-45S from Europe to the USA.

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").
