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

Hi,

does anyone know more info about the Dorand DH-014 and DH-015 projects ?,
I think they were helicopters.

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......
