history
Papin-Rouilly Gyroptère
The gyroptère was designed by Alphonse Papin and Didier Rouilly in France between 1913–1914 , inspired by maple seeds. Papin and Rouilly received French patents and a US patent in 1915.
The gyroptère was described in the French journal La Nature in 1914 as “un boomerang géant” (a giant boomerang ).
Bölkow Bo 102 and Bo 103
The Bölkow Bo 103 was a research project for a training helicopter commissioned by the German Ministry of Defense in 1961 at Bölkow Developments KG . The Bo 103 was a further development of the Bo 102 helicopter trainer, which was attached to a floor frame . Both types had a GRP single-blade rotor made from one piece with a counterweight. The diameter of the rotor area was 6.57 m. While a small series of the Bo 102 was launched, only a prototype of the Bo 103 could be produced in 1962 due to a lack of interest from the German military.
