The Junkers F 24 was the single-engine freighter conversion of the Junkers G 23 and G 24 types .


Ernst Zindel was responsible for the renovation . Compared to the G 24, the passenger area has been cleared and the luggage compartment and wet room have been expanded. The wing center pieces, on which the two outer motors of the G 24 hung, were removed, which reduced the wingspan. This conversion was carried out for the first time in the spring of 1928.

Initially, a 551 kW (approx. 750 hp) BMW VIu was installed; these planes (seven pieces) received the designation F 24ko.

Further modifications (F 24kau) received the 507 kW (approx. 690 hp) BMW VIIau , which, however, was ultimately not built in series.

The version F 24kay received a 529 kW (about 720 hp) 2-stroke - diesel - opposed piston engine Junkers Jumo 4 . This conversion was preceded by tests with a Junkers F04 engine in 1929. This conversion was so successful that some models that had already been converted from G 24 to F 24 were converted to this engine again.
