A more efficient internal combustion engine
This thing is fascinating to watch in action. I enjoyed the post.
It's also known as a wabble-plate engine. If you go the the Air Force Museum in Dayton Ohio, you can see a large wabble-plate engine built by the Germans in WWII to experiment with a possible new air craft engine technology. I worked on a torpedo ...It was the Mark 46 torpedo ..it had a wabble-plate engine..my job was to trouble shoot preproduction guidance electronics problems. I digress. It was powered by a solid state rocket body..the hot gas from the rocket motor drove the wabble plate engine ...to this day I don't know how fast this torpedo was ...I think it was about 60 mph. Also, all the Fridigdaire A-6 air conditioner compressors on 60's to mid 70's cars utilized wabble plate compressors
Nothing really new about wabble-plate engines or their mechanics, but it's good to see a good design live on.
