The PZL P.24 was a single-engine fighter aircraft built in Poland from the 1930s. It was internationally successful and was exported to Turkey , Bulgaria (12 pieces), Greece and Romania or (40 P.24E) built under license , with the majority of the machines (40 P.24A and 26 P.24C) going to Turkey went.
history
Development work began in February 1932. Zygmunt Puławski's PZL P.11 , the standard fighter aircraft of the Polish Air Force at the time, served as the base . The airframe was taken over from her. Initially, a French Gnome-Rhône 14Kds Mistral Major with 760 hp served as the drive .
The first flight of the prototype P.24 / I took place in May 1933 and almost ended in a catastrophe when the propeller came off the engine and the machine had to make an emergency landing. As a result, the tests were delayed and could only be resumed in October. After defects appeared, some changes were made in the bow area. The engine fairing was lengthened a little and a three- bladed propeller was used instead of the two-bladed propeller .
This second prototype, known as P.24 / II or Super P.24 , was tested in 1934 and in the same year set an FAI speed record of 414 km / h in its class.
The most obvious change in the third machine was a closed pilot cockpit and a 930 hp Gnome-Rhône 14 Kfs engine . The designation was P.24 / III or Super P.24bis . In 1934 the two Super P.24s were presented to the public at the Paris Aviation Salon ; then some orders were placed from abroad.
In Romania, the low - wing aircraft IAR-80 was developed in 1939 based on the P.24 and also built in series. In Greece, the P.24 provided the bulk of the fighter squadrons and was deployed in the Balkan campaign against the German and Italian air forces.
construction
The P.24 was a stripped shoulder- wing aircraft in all-metal construction. The distinctive Puławski wing had two spars in a double-T shape and sheet metal planking. The braced normal tail was also made of metal. The main wheels of the rigid chassis had a streamlined fairing. There was a grinding spur at the stern.
