Caudron-Renault CR.713

CR.714 Cyclone - light wooden fighter. The first flight of the prototype on July 18, 1936.

The production aircraft received the designation Caudron-Renault CR.714C1, it was equipped with a Renault 12R-03 liquid-cooled engine with a three-bladed variable-pitch propeller with a diameter of 2160 mm.

The armament of the CR.714C1 consisted of four 7.5-mm machine guns installed in pairs in fairings under the wing consoles (300 rounds of ammunition per barrel). The sight is a collimator. There was a photo-machine gun.

CR.714C1 was hardly used by French pilots. A small part of the planes ended up in Finland, the ones that remained in France were transferred to Polish aviators.

On November 30, 1939, the Soviet-Finnish war began. It was supposed to send a fighter air group, armed with CR.714C1 and manned by Polish pilots, to Finland. In total, France was ready to provide Finland with 80 CR.714C1 aircraft. But everything was limited to the supply of only a few aircraft, and the Finns themselves flew on them.

In total, about 90 fighters were built.

In some ways, the CR.714 fully met the requirements for fighter aircraft. So, its wing load was 140 kg/m² - for other French fighters of that time, this value was in the range of 150-170 kg/m². But the power load differed much more significantly: 3.9 kg/hp against 2.5-2.9 kg/hp And if the load on the wing largely determines the speed and maneuverability of the aircraft, then the load on the power characterizes the ability to realize these qualities. A small thrust reserve for a fighter is highly undesirable. In some sources, however, "Cyclones" are characterized as quite maneuverable. Perhaps the main role here is played by the aircraft's low weight and small absolute wing dimensions, which improves the fighter's response to unsteady modes of motion.
