Rigid Airship Design and Construction: An Account, Hitherto Unpublished, of the Design Considerations Leading to the Principal Features of R 100 Available to Purchase

THERE are two outstanding principles which underlie all airship design, two criteria by which everything undertaken may bo judged. The first is that the body produced shall offer a minimum of resistance to propulsion through the air; the second is that, having shaped a body in that way, it shall give a maximum of disposable lift for a given volume. An airship also, at the present time at least, must be produced for a minimum of cost. For this reason every effort must be made to design the structure as cheaply, as economically, and as quickly as possible.
