I've been reviewing many designs of the zeppelins of old, and started designing my own.. The BZ-1 is my nickname for it (Ben's Zeppelin, lol). Here are some basic plans, stats, 3D mock-ups, etc.
NOTE: All dimensions given below are in cm, for the model, but would be in normal meters for the full sized version.
Length: 300cm
Largest Diameter: 44cm
Framework: 20 main frame rings, 16 longitudinal girders
Control Surfaces: Horizontal and Vertical fins between rings 4-1, control surfaces extend past that, are roughly 4.5x16cm square(less surface area)
Gas capacity: 17 18" mylar balloons, unknown volume or lift yet, requires further experimentation.
Motors: two at ring 10, two more at ring 14.
