Derek Caelin apžvelgė autoriaus Iver P. Cooper knygą Airships
Everything you every wanted to know about airships but were afraid to ask
4 žvaigždutės
Most books about airships fit into one of two categories: "Aren't they beautiful?" or "The horrendous explosion: how it happened." "Airships: Their Science, History and Future" is focused on the "how" of airships; the technical challenges that engineers have tackled since the technology emerged. How is lift generated? What causes drag? Where is the greatest strain on the frame? What do do you use for fuel? How do you navigate? Cooper - a retired patent attorney - is technical and methodical, providing tables, formulas, and statistics on everything from the lifting power of gasses to models for calculating drag. I came away with a new appreciation for how challenging it is to build an airship, even with today's technology.
