The concept of disc-shaped MHD aerodynes has been introduced by Jean-Pierre PETIT in 1975, in 2 papers released in the “Comptes Rendus de l’Académie des Sciences de Paris”. Bringing out first the Velhikov instability and then cancelling it are two major steps to the experimentation and achievement of such aerodynes.
A state of the art as well as a status on our works progress are given in the following dedicated page : Spiral Currents disc-shaped Aerodynes
