Specification and Design
Norge was the first N class semi-rigid airship designed by Umberto Nobile and its construction started in 1923. As part of the selling contract it was rebuilt for Arctic conditions. The pressurised envelope was reinforced by metal frames at the nose and tail, with a flexible tubular metal keel connecting the two. This was covered by fabric and used as storage and crew space. Three engine gondolas and the separate control cabin were attached to the bottom of the keel. Norge was the first Italian semirigid to be fitted with the cruciform tail fins first developed by the Schütte-Lanz company.

Famous quotes containing the word design:
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
