BUICK's 1956 twin-turbine Dynaflow transmission incorporates a fixed-blade stator between the two turbine elements.
Added to the twin turbine (introduced in 1953) and the variable-pitch stator (introduced in 1955), the author says, this has made an important contribution to reduction in engine rpm, increased low-end performance, and improved efficiency.
Stall ratio has been increased from 2.45/1 to 3.5/1, and “getaway” on low-end car performance has improved.
