TheDewoitine D.19was afighter aircraftbuilt inFrancein 1925 in response to aFrench Air Forcesolicitation.
Design and development
[edit]A development of theD.1,the D.19 shared the D.1'sparasol-wingconfiguration, but featured an all-new wing of increasedspan,and had double the engine power. Although rejected by the French Air Force, a demonstration for theSwiss governmentin August 1925 led to an order for three aircraft. An additional example was sold toBelgium,incorporating the same changes requested by the Swiss. These included a change in the wing (changing back to become more similar to the D.1), and the replacement of theLamblin radiatorswith a more conventional frontal radiator.
Operational history
[edit]While the first Swiss D.19 was entirely constructed by Dewoitine in France, the remaining two aircraft were supplied to be assembled by the Swiss factoryEKW.The aircraft were used for many years by the SwissFliegertruppeas trainers for fighter pilots, remaining in service until 1940. All three participated in the international aviation meet atDübendorfin 1927, with one of the D.19s winning the closed-circuit race.
