Rigid as a keyword means 'rigid airship' — i.e. a design using an inflexible frame. The rigid airship is said to have been invented in the late nineteenth century. Joseph Spiess and David Schwarz were some early designers working along these lines. Ferdinand von Zeppelin, who began constructing Zeppelins around the turn of the century, is the best known rigid-airship maker.

The rigid airship is more expensive and difficult to build but has the advantage of maintaining its shape despite changes in atmospheric pressure and quantity of gas.[1]

  1. ↑ Berget, 1909, Conquest of the Air, p. 29:

    The external form is invariable, thanks to the material of the envelope and the framework on which it is stretched.
    We see at a glance what colossal difficulties such an arrangement presents, the difficulty of constructing a trellised cylinder 120 metres long and 11 metres wide to say nothing of its expense; the difficulty of fixing the external envelope, and finally, the complication of inflating the elementary balloons contained in each of the compartments. Experience has shown the difficulty of managing such masses both at starting and landing: we shall return to this question later on. In any case it is difficult, and also very perlious, to give the body of an airship a rigid substructure.
