Traian Vuia or Trajan Vuia (Romanian pronunciation: [traˈjan ˈvuja]; August 17, 1872 – September 3, 1950) was a Romanian inventor and aviation pioneer who designed, built and tested the first tractor monoplane. He was the first to demonstrate that a flying machine could rise into the air by running on wheels on an ordinary road. He is credited with a powered hop of 11 m (36 ft) made on March 18, 1906, and he later claimed a powered hop of 24 m (79 ft). Though unsuccessful in sustained flight, Vuia's invention influenced Louis Blériot in designing monoplanes. Later, Vuia also designed helicopters.
