Dewoitine D.513

The Dewoitine D.513 was a 1930s prototype French monoplane fighter designed and built by Dewoitine.

Development

The D.513 was a single-seat low-wing cantilever monoplane fighter that first flew on 6 January 1936.^[1] The D.513 was powered by a 860hp (641kW) Hispano-Suiza 12Ycrs1 inline piston engine and had a retractable tailwheel landing gear.^[1] Testing proved that the D.513 was unstable and not able to reach the expected speeds and it was rebuilt with a new fuselage and a modified tail unit.^[1] The changes did not improve the stability or the maximum speed and problems were also found in the engine cooling and landing gear, further development was stopped.^[1] The second prototype was modified with landing gear and a radiator from the D.503, it was re-designated the D.514LP and was used in high-speed parachute trials.^[1]
