My dear Apophenia,that suggesting to be more smoothly fusdelage with minor changes of course,butI am niot sure,here is its description;The D4 S2 push-pullIn 1934 Paul Deville studied a two-seater twin-engine aircraft in tandem with a push-pull formula, very innovative for the time. The aircraft was to be equipped with two Salmson 9 Adr 60 hp engines. the wing,cantilever and trapezoidal in shape, was placed on the back of the small fuselage. She had a wingspan of 11.40 m. Two beams, spaced 2.50 m apart, supported the empennages whose rudder, placed in the middle of the horizontal tail, was in the blast of the rear propeller and outside the deflection of the wing.The fixed landing gear included two cased wheels at the front and a rear wheel placed under the vertical stabilizer. It was built as a wind tunnel model, but the formula seemed too audacious at the time for any practical realization to be undertaken. Its maximum speed was estimated at 200 km/h.
