The Druine D.31 Turbulent is a French single-seat ultralight Homebuilt aircraft designed by Roger Druine.[1]
Development
The D.31 Turbulent was designed to be amateur-built and is a single-seat ultra-light aircraft with cantilever low-wing and fixed tailwheel landing gear. Designed to be powered by a 30hp (1200cc) Volkswagen or similar engine.[2] The fuselage uses wood construction.[3] Rollason Aircraft & Engines Limited produced 29 factory-built D.31 aircraft in the United Kingdom and three D.31A models with strengthened wing spar in order to get a full British certificate of Airworthiness. Five Turbulents are operated by the Tiger Club in 2008.[4]
The rights to plans for the design are held by the UK Light Aircraft Association.[5]
