The Dewoitine D.33 (nickname: Trait d'union , dt .: hyphen ) was a single-engine long-range test aircraft produced in 1929 by the French aircraft manufacturer Dewoitine , which was designed and built for the purpose of long-distance record flights. The characteristics of the two machines were F-AKDV and F-ALFC.
The following types D-333 , D-338 and Dewoitine D-342 were developed on the basis of the D.33 .
history
The D.33 was a three-seat, all-metal low- wing aircraft with a rigid landing gear . A Hispano-Suiza 12NB in-line engine with 650 hp provided the drive . The first flight took place on November 21, 1930. Of this basic type, on which the types D.333 , D.338 and D.342 were based, only two pieces were built.
The "Trait-d'Union" (F-AKDV)
The first D.33 set a long-distance record for circuits from June 7 to 10, 1931 with the pilots Marcel Doret and Joseph Le Brix and the mechanic René Mesmin , when it covered 10,520 km in 70 non-stop flight hours. She had already set seven world records in March. Then the three tried the first non-stop flight from Paris to Tokyo with the “Trait-d'Union” . They started on July 12, 1931 in Le Bourget and reached close to Lake Baikal in Siberia . Her engine froze there. Le Brix and Mesmin jumped off with their parachutes , and Doret lowered the machine into the treetops in a forest. The “Trait-d'Union” was a total loss, but the three planes were unharmed.
The "Trait-d'Union II" (F-ALFC)
Then a second D.33 was built, the "Trait-d'Union II". On September 11, 1931, the same crew started a new attempt with the “Trait-d'Union II”. On the morning of September 12th, while flying over the Urals near Ufa , their engine failed again and they had to give up the plane. This time Doret jumped first. It is believed that Mesmin had difficulty with his parachute and Le Brix did not want to leave his friend alone. The two were killed in the plane crash and the subsequent fire.
Today there are no more D.33s because both crashed and were total losses.
