F01D 1/02 with stationary working-fluid guiding means and bladed or like rotor
F01D 1/18 without working-fluid guiding means
F01D 1/24 characterised by counter-rotating rotors subjected to same working-fluid stream without intermediate stator blades or the like
F01D 1/3 characterised by having a single rotor operable in either direction of rotation, e.g. by reversing of blades
F01D 1/32 with pressure/velocity transformation exclusively in rotor, e.g. the rotor rotating under the influence of jets issuing from the rotor
F01D 1/34 characterised by non-bladed rotor, e.g. with drilled holes
