I'm in Charlotte, North Carolina for my step-daughters wedding tomorrow, and I found out this morning that there's a small aviation museum over at the Charlotte/Douglas Int'l Airport, so I stopped by to check it out. It's the Carolinas Aviation Museum, which is home to a beautiful DC-3 in Piedmont colors (more on that in another post) along with several military aircraft as well as a handful of other classic airplanes. But the unique flying machine that really caught my eye was the turbine powered Gyrodyne QH-50C coaxial DASH (Drone Anti-Submarine Helicopter) that was put into service with the U.S. Navy in the early 60's.
It's really interesting to see that 50 years ago we had an unmanned, remotely piloted vehicle that not only effectively used coaxial rotors, but was even designed to deliver submarine destroying torpedoes. The QH-50 was small, with just a 20' rotor diameter, but it was full of forward-thinking ideas. You can expect a more detailed post in the future on this unique 'old-school' UAV, but til then, check out this really short video below to get an idea of how the QH-50 operated. Very cool stuff.
