Gutenburg
"In 1906, Major von Parseval experimented, in Berlin,
with a non-rigid type of airship. His first ship had a
volume of 65,200 cubic feet, but owing to his system of
suspensions, the car hung 27 feet 6 inches below the envelope.
A Daimler engine was used, driving a four-bladed propeller.
Owing to the great overall height of this ship, experiments
were made to determine a system of rigging, enabling the
car to be slung closer to the envelope, and in later types
the elliptical rigging girdle was adopted. His later ships
were of large dimensions and proved very satisfactory." |
