Vulcan Traveller

vulc-travel


Single-seat single-engined high-wing monoplane with two-axis control. Wing has swept back leading and trailing edges, and tapering chord; no tail, canard wing. Pitch control by fully flying canard; yaw control by tip rud-ders; no separate roll control, control inputs through stick for pitch/yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile; double -surface. Undercarriage has three wheels in tricycle formation; suspension on nose-wheel and glass-fibre suspension on main wheels. Push-right go-left nosewheel steering independent from yaw control. Brake on nosewheel. Aluminium-tube framework, without pod. Engine mounted below wing driving pusher propeller.
These aircraft are Germanisations of the Fledgling designed by Klaus Hill. The Vulcan uses the Fledge in conjunction with a canard. This company, however, has instead of using a one-piece canard, the Traveler uses two mobile surfaces articulated separately from the aircraft's two main horizontal tubes. Acting as elevators, these two surfaces are operated from the stick via a push rod.
The frame has been completely redesigned by Vulcan. The wings used are Fledge II or Fledge III, but Vulcan modifies them by adding trapezoidal vertical surfaces acting as winglets, to reduce tip vortices. Travelers are available under the name of Traveller II or Traveller III, depending upon the wing used, deli-vered built but without power pack. This is either a Lloyd 22 hp or the Cuyuna 430R 30hp.
Two propellers were on offer, one a fixed pitch two-blade and the other a three-blade ground-adjustable pitch. Only 20 examples had been produced by March 1983 and sold purely in West Germany.
