Design

Following closely to the winning formula that Levavasseur had introduced, the Antoinette V introduced a revised undercarriage, with a closely spaced pair of mainwheels at the rear of a carriage/skid which extended forward of the propeller, a tail-skid attached to the lower fin framework prevented damage to the tail section. Lateral stability on the ground was provided by outrigger wheels supported by a wire-braced framework at about half-span.

Design and development

A development of the Antoinette IV, the Antoinette V differed somewhat in having increased upper vertical tail area with no fabric covering the lower fin framework. The fuselage consisted of a wooden framework of triangular section covered with fabric, except in the cockpit area abreast the wing trailing edge. The wings were built in a similar fashion and were also covered in fabric.

Control was affected by wheels either side of the pilot's seat for roll and pitch, and a rudder bar for yaw. The pilot operated a triangular elevator hinged to the tailing edge of the large tailplane, rhomboidal ailerons hinged from the trailing edges of the wingtips, and two triangular rudders above and below the tailplane.

Delivered to Réné Demanest, the Antoinette V proved easy to fly and enjoyed some success.[1]
