Propeller planes give an endless source of inspiration to design wind turbines. A lot of propeller planes are also vintage machines, that retain the glory of the early days of aviation, as we are in the early days of domestic wind generation. Obviously its shape and materials are not directly suitable to be transferred to small wind turbines. Without abandoning Mc Donell Douglas vintage airliners it can be equally admired DC-3 and DC-7 series spinners. While DC-3 have a charming old fashioned mechanical design, DC-7 belongs to the wide streamlined family of modern spinners.
In first picture a DC-3 spinner can be seen, and Red Bull has its own shiny and flawless vintage airliner.
Some of this stuff are well priced collectors items. A vintage propeller in good condition can sell from 1000 to 10.000 USD.
