ThePotez 230 was a French lightweight single-seat, single-enginedfighter aircraft. One prototype was built and flew in 1940, but no production followed, with the prototype being captured and shipped to Germany for study.
In 1936,ANF Les Mureaux designed and flew theANF Les Mureaux 190, a lightweight single-engined fighter aircraft powered by a 340 kW (450 hp)ANF Les Mureaux 190 engine and with a fixed undercarriage. The unreliability of the engine caused the 190 to be abandoned in 1937.[1] Despite this setback, and the nationalisation of ANF Les Mureaux to form part of the state-ownedSNCAN combine, the former design team of Les Mureaux, René Lemaitre and Hubert led by André Brunet, did not abandon the concept of lightweight fighters, and in 1938, began work on the Potez 230,[a] a more advanced development of the Les Mureaux 190.[4][5]
Like the earlier aircraft, the Potez 230 was a low-wingcantilevermonoplane, with a similarelliptical wing. The wings were built around an integraltorsion box, the first example of this structure to have flown, and were fitted with split trailing-edgeflaps. The aircraft'sfuselage was of oval cross-section, with the pilot accommodated in an enclosed cockpit. The aircraft was powered by a 500 kW (670 hp)Hispano-Suiza 12XcrsV12 engine driving a three-bladedRatier propeller in atractor configuration. Armament was planned to be a single Hispano-Suiza 20 mm cannon mounted between the engine cylinder banks and firing through the propeller, with four 7.5 mm machine guns to be mounted in the wings.[5][6]
The unarmed prototype made its maiden flight atVillacoublay on 30 March 1940.[4] Testing was relatively trouble-free, with the aircraft reaching a speed of 439 km/h (273 mph) at sea level and 560 km/h (348 mph) at 5,000 m (16,400 ft), with it being planned to fit a more powerfulHispano-Suiza 12Y engine. TheGerman invasion of France disrupted testing, however, with the prototype captured by the Germans when they seized Villacoublay airfield in June 1940. The Germans were interested in the novel wing torsion box, and the prototype, together with all available drawings and data, was shipped to Germany for closer study.[5][6]
