Del
BO-46 se construyeron tres prototipos por pedido del Ministerio
de Defensa Alemán, que servirían para probar el rotor semirígido
Derschmidt. El primer modelo, construido conjuntamente con SIAT, comenzó
sus pruebas de vuelo en enero de 1964. El rotor Derschmidt sufrió una
larga serie de pruebas en túneles de viento. Cada pala tenía una bisagra a
la mitad de su radio, habilitando a la sección externa a rotar 40º
hacia atrás o hacia delante en relación a la parte interna de la pala.
Este movimiento permitía que la pala que avanzaba se “demorara”
considerablemente reduciendo la velocidad de la puntera de pala. Sin
embargo, la complejidad del sistema impidió que el BO-46 pasara
de la etapa experimental. |

The Bolkow Bo.46, three experimental prototypes of which were built for the German Ministry of Defense, served as a flying test-bed for the Derschmidt semi-rigid rotor. The first model, built jointly with SIAT, began test flights in January 1964. The Derschmidt rotor underwent a long series of wind tunnel tests, for each blade had a hinge about half-way along its radius, enabling the outer section of the blade to rotate 40° backwards or forwards in relation to the inner section connected to the hub. This enabled the movement of the advancing blade to be "delayed," thereby considerably reducing the tip speed. Conversely, by "accelerating" the movement of the outer portions, quite high rotational speeds could be achieved. However the complexity of this system prevented the Bo.46 from passing the experimental stage. G.Apostolo "The Illustrated Encyclopedia of Helicopters", 1984 |
