Flight, December 1930
The PARIS AERO SHOW
Of the four machines exhibited by Dewoitine, two are of the familiar D.27 type, one a single-seater fighter, and the other a training machine. The former has a 500 h.p. Hispano-Suiza engine, while the
school machine has a Gnome-Rhone Titan radial air-cooled of 300 h.p.
The other two machines are commercial types. The D.30 is a large commercial cantilever monoplane, single-engined (650 Hispano-Suiza), and of all-metal construction. The fuselage is metal-covered, and the wing is metal-covered from leading edge to mid-chord. A ridiculously small Lamblin radiator under the belly of the fuselage looks wholly inadequate for dealing with a 600-h.p. engine. The D.30 is designed to carry 10 passengers.
The main data relating to the Dewoitine D.30 are: length, 14 m. (45 ft. 11 in.); wing span, 25-18 m. (82 ft. 6 in.); wing area, 65 sq. m. (700 sq.ft.); tare weight, 2,476 kg. (5,425 lb.); gross weight, 4,486 kg. (9,875 lb.); maximum speed, 215 km./h. (133 m.p.h.); range, 860 km. (535 miles).
