Optimized aerodynamic, propulsion, structural and operations features for lighter-than-air vehicles

摘要

An optimized lighter-than-air vehicle or airship incorporating a frame 104, internal propulsion 124, perforated covering 102 and lifting-gas cells 110 is disclosed. Optimization features include variations on a Stratford Ramp, means to control the boundary layer 210, absence of unnecessary protuberances and means to reduce the bow wave. A transportable version utilizing a flexible frame 310 and keels 314 is also disclosed along with a means for rapid descent and landing. The operating concept reduces velocity requirements which, in turn, reduce weight and size requirements.
