The Nord Aviation N 500 Cadet was a single-seat VTOL research aircraft built by Nord Aviation in 1967.
A model kit presenting the concept was first shown at the Paris Air Show at Le Bourget in 1965. The aircraft was driven by two ducted fans, with three blades per fan, mounted on short wings that were able to pivot between providing vertical and horizontal thrust.
Two prototypes were constructed, one making its first (tethered) flight in July 1968.
