Heinkel He 1

Svenka S.1


In the early 1920s German aviation development was severely restricted by the 1919 Treaty of Versailles and the 1922 Committee of Guarantees. The latter allowed only limited production and the use of very low-powered engines. Ernst Heinkel, in common with other German aircraft manufacturers of the period, had his designs built abroad. He formed his own company on December 1, 1922, and its first product was the He 1 single-engined three-seat seaplane monoplane, which flew for the first time in May 1923. It was built under licence by the army workshops in Sweden and was designed to take engines in the 250-hp range. The engine commonly fitted on production models was the 240-hp Armstrong Siddeley Puma or 179kW Maybach Mb IVa. He 1s served mainly as trainers with the Swedish navy. In Sweden the He 1 and 2 were designated S 1 and S 2 respectively.
