The History and Future of Blimps
TLDR This podcast episode explores the history of blimps, from their origins as hot air balloons to the development of powered airships. It also discusses the Hindenburg disaster, the design and components of blimps, and the current challenges faced by the industry, including a helium shortage.
Timestamped Summary
00:00
This section of the podcast discusses the different names and types of blimps, as well as the history of blimps starting with hot air balloons.
04:42
The blimp is distinctive in its shape and maneuverability, and the first powered airship was built in 1852 with a steam engine, while the first rigid airship was built in 1900 by Count Ferdinand von Zeppelin of Germany.
09:08
The Hindenburg airship arrived in Lakehurst, New Jersey about 12 hours late due to poor weather, and after waiting for conditions to improve, the blimp attempted to land but caught fire and burned in less than a minute, resulting in the death of many passengers and crew.
13:53
The Hindenburg disaster was likely caused by an electrified envelope that ignited a hydrogen leak, leading to the end of commercial blimp travel, although blimps continued to be used by the military and Goodyear.
18:21
Blimps are simple in design, with the most complicated part being the gyroscopic camera on the front, and they are filled with helium and made of lightweight, strong materials like neoprene polyester.
23:41
Blimps have ballonettes, which are air bladders located within the envelope that can be inflated or deflated to control the blimp's altitude.
28:28
Blimps have engines, flight controls, and air valves that allow them to stay aloft for long periods of time and consume very little fuel.
33:14
Blimps have various components, including a cargo hold, communications equipment, flight surface controls, and propeller controls, and they require a ground crew for maintenance and repairs.
38:19
Blimps use helium, which has a lift capacity of 0.70 pounds per square foot, to achieve positive buoyancy and rise into the air, and they achieve neutral buoyancy by controlling the air bladders; however, there is a helium shortage due to the government selling off the strategic helium reserve in Texas.
42:55
The helium shortage is due to the high demand from the medical, pharmaceutical, and welding industries, as well as party balloons, and there are concerns about the future of airships due to lack of funding and the inability to fulfill orders for helium.
47:36
The hosts wrap up the episode by sharing listener mail and promoting their social media accounts and website.
