ABSTRACT OF THE DISCLOSURE A turbine has a disc pack rotor with a central aperture-free or solid disc that divides the pack into two equal portions. The annular discs of each portion have aligned, central and unobstructed exhaust openings and the outer end disc of each portion is a support member having a webbed hub that is attached to a respective drive shaft journalled in the turbine cas- ing. A stationary circular nozzle assembly closely surrounds the outer cir- cumference of the disc pack to form one or more convergent-divergent nozzles that guide motivating fluid from an outer casing plenum into spaces between neighboring discs. The discs are separated from one another and intercon- nected by fences that guide the motivating fluid to the exhaust openings in each pack portion. Thus, fluid enters the pack circumference and is split into two parts by the center disc to exhaust in relatively opposite direc- tions. The shaft for each pack portion preferably terminates at the outer support disc to form a two-direction "shaftless" rotor.
