The Stampe et Vertongen SV.4 (also known as the Stampe SV.4 or just Stampe) is a Belgian two-seat trainer/tourer biplane designed and built by Stampe et Vertongen. The aircraft was also built under licence in France and Algeria.

History

The SV.4 was designed as a biplane tourer/training aircraft in the early 1930s by Stampe et Vertongen at Antwerp. The first model was the SV.4A an advanced aerobatic trainer followed by the SV.4B with redesigned wings and the 130 hp/97 kW de Havilland Gipsy Major.

Only 35 aircraft were built before the company was closed during the Second World War. After the war the successor company Stampe et Renard built a further 65 as trainers for the Belgian Air Force. A licenced SV.4C version was built in France by SNCAN and in Algeria by Atelier Industriel de l'Aéronautique d'Alger building a combined total of 940 aircraft.

Variants

;SV.4: prototype;SV.4A: aerobatic trainer with 140 hp/104 kW Renault 4-PO5 engine;SV.4B: improved version with 130 hp/97 kW de Havilland Gipsy Major I. Post-war trainers for the BAF were fitted with more powerful Cirrus Major or Gipsy Major X;SV.4C: licence built version with 140hp/104 kW Renault 4-Pei engine;SV.4D: one aircraft re-engined with 175 hp/130 kW Mathis engine
