The PZL.45 Sokół ( German falcon ) was a Polish fighter aircraft project that was developed by PZL between 1936 and 1939 and did not get beyond the prototype stage before the Second World War .
history
Work on a new fighter aircraft for the Polish Air Force began in the late 1930s. At the end of 1938, the design work was completed and PZL was commissioned to build the prototype. A mockup of the aircraft was completed in February 1939. The technical documentation was completed in June 1939. The construction of the first prototype, which had a rigid landing gear, was still under way, but was no longer completed because of the outbreak of World War II. The unfinished prototype was destroyed in the first week of the war. A second prototype should have received a retractable landing gear.
The aircraft, made entirely of metal, was designed as a low-wing aircraft with a closed cockpit. The prototype produced was unarmed, the production version should have had one board cannon on each side in the wings and two board cannons firing through the propeller circle in the fuselage.
construction
The PZL P.45 was a single-seat, single-engine, cantilever low- wing aircraft with a normal tail unit and a fixed tail wheel landing gear . A retractable landing gear was provided for later versions.
