Canadian Vickers Vanessa - Design and Development

Design and Development

The Vanessa was developed as a private venture commercial seaplane. The Canadian Vickers Chief Engineer based his design on the contemporary Stinson cabin biplane which had been introduced in the United States. The one feature that was a departure from the Stinson was the use of interplane struts which formed an "X" (when viewed from the front), thus eliminating the need for traditional wire bracing and allowing easy access to the cabin. The enclosed cabin fuselage was constructed of steel tubing as were various support structures along with the tail surfaces. The remainder of the aircraft was of wood construction and the entire aircraft was fabric covered.

Ailerons and flaps, the latter being an unusual feature in aircraft of that time, were fitted to each of the equal span wings and were also interconnected by struts.
