Do you know what they use to swing those wings? It's a thermal wax

Tom, do you have a website where this is described? I'm having a
hard time believing it. I'm a retired airline mech. and never worked
on any swing wing aircraft. Just all the big Boeings, Airbus,
Lockheed etc. I did a google search and came up with nothing.



I heard it from a cousin working for Loral aerospace as a design
engineer, now retired, he worked on many cool projects, a lot of which
will never see daylight. Wax motors are more common than we think. I
couldn't easily find any direct references, but I'll ask next time I
talk to him.
