Attached the Dorand DH-2011 - jet-flap-rotor of 1967. Any ideas exactly what a jet-flap-rotor does?

They were helicopters, and I think I saw some pictures of them here somewhere.

Dear Boys and Girls, here is an article in French about the Société d'Études des Giravions Dorand jet-flap hot-cycle helicopter rotor system designed by René Dorand......

The article comes from the 5th May 1961 issue of Les Ailes......
