Flight, December 1924
The Paris Aero Show 1924
CONSTRUCTIONS AERONAUTIQUES E. DEWOITINE
A COMPARATIVE newcomer to the French aircraft industry M. E. Dewoitine, whose experimental works and offices are now at Chatillon-sous-Bagneux (Seine), while the original
works at Toulouse are devoted to quantity production, is rapidly gaining a leading position among French aircraft designers. Probably the first introduction of M. Dewoitine to readers of FLIGHT dates back to the 1920 Paris aero show, when a scale model of the Dewoitine twin-engined commercial monoplane was shown. Incidentally the same machine is, we understand, being produced as a night bomber. At this year's Paris Show M. Dewoitine is showing four machines, two of which are of the D.1 C.1 type, while the third is the D.7 light monoplane, and the fourth a large commercial monoplane.
The Dewoitine commercial monoplane, the D.14, is a large machine intended to be used either as a freight carrier or as a passenger machine. As exhibited, it is fitted up to carry six passengers, but the seats can be removed in order to convert the saloon into a freight hold. The space is really divided into three separate compartments, of which normally the front one is intended for freight and/or luggage, while the central cabin has four seats and communicates with the third compartment, containing the lavatory. At the show the front compartment is provided with two seats, giving a total passenger accommodation of six. The machine is of wood construction, but presumably if it were to be ordered in quantities it could be turned out in metal. The construction is straightforward, and does not call for comment. The main dimensions, weights, etc., are as follows: Length overall, 12-2 metres (40 ft.); height, 3-35 metres (11 ft.); wing span, 18-8 metres (61 ft. 8 ins.); wing area, 45-5 sq. metres (490 sq. ft.); weight of machine empty, 1,850 kgs. (4,070 lbs.); weight of fuel and oil (for four hours), 350 kgs. (770 lbs.); useful load, 600 kgs. (1,320 lbs.), i.e., pilot and accessories, 100 kgs. (220 lbs.), and passengers and/or freight, 500 kgs. (1,100 lbs.). Total loaded weight, 2,800 kgs. (6,160 lbs.). The machine exhibited is fitted with 450 h.p. Lorraine type 12 EW, but the engine mounting is so designed that the engine can quickly be changed, and, if desired, a 450 Hispano or 500 Salmson can be fitted instead. The Dewoitine D.14 has a speed at 2,000 metres, of 180 km./h. (112-5 m.p.h.) and a landing speed of 78 km. /h. (48-75 m.p.h.).
