Good morning,
I'd like to mention that I worked as an engineer
for an airship company for several years in the mid-1980's. My company
developed the Cyclo-crane and Aero-cran - a combination between an airship
and a helicopter. (It really requires a picture to give the idea)
Anyway I'm a good source for flight dynamics and physics models of airships
including apparent mass, insolation and basic dynamics. If anyone is
interested I can provide pictures and drawings of the cyclo-crane and some other
airships as well - I've got a limited selection of general publications on the
subject in addition to my notes and reports from when I worked in the
field.
By the way, I did a quick search on the web and was
unable to find a picture of either the Cyclocrane or Aerocrane. However,
it was featured on a PBS episode and the video (which also includes a brief
history of airships and some of the novel contemporary concepts of the
mid-80's) may be available at your local library.
I found it mentioned at this one http://www.wheaton.lib.il.us/library/pdf/VHSscience.pdf
I also have detailed blueprints of the Navy K-type
Goodyear blimp and a production prototype that shared our hangar (which ended up
embarassingly skewered by the antenna of a New York City
skyscraper.
Contact me privately if you are interested in any
further information. I will try to find a picture of the Cyclocrane to
scan and post.
