A counter-rotatable fan turbine engine (10) includes a counter-rotatable fan section (112), a worm gas generator (100), and a low pressure turbine (120) to power the counter-rotatable fan section (112). The low pressure turbine (120) maybe counter-rotatable or have a single direction of rotation in which case it powers the counter-rotatable fan section (112) through a gearbox (224). The gas generator (100) has inner and outer bodies (12, 14) having offset inner and outer axes (16, 18) extending through first, second, and third sections (24, 26, 28) of a core assembly (15). At least one of the bodies is rotatable about its axis. The inner and outer bodies (12, 14) have intermeshed inner and outer helical blades (17, 27) wound about the inner and outer axes (16, 18) and extending radially outwardly and inwardly respectively. The helical blades have first, second, and third twist slopes (34, 36, 38) in the first, second, and third sections (24, 26, 28) respectively. A combustor section (40) extends through at least a portion of the second section (26).
