Study on the Radial Air Turbine
Transactions of the Japan Society of Mechanical Engineers, 1961 The experiments were made on a rdial air turbine which was designed on the assumption that the outlet axial velocity is constant. Beside the usual measurements of pressures and temperatures, the flow was observed by a precise yaw-meter survey at several points of the machine.

Radial turbine meshing and optimisation [PDF]
, 2018 Radial turbines are a class of turbomachinery that extracts work from a high-energy workingfluid. Contrary to an axial turbine seen on commercial aircraft, where the working fluid (air)travels through the turbine without having a bulk change in direction, radial turbines createhighly three-dimensional flow, with the fluid leaving the turbine ...

Cooled Radial In-Flow Turbines for Advanced Gas Turbine Engines [PDF]
Volume 1: Aircraft Engine; Marine; Turbomachinery; Microturbines and Small Turbomachinery, 1981 While the radial in-flow turbine has consistently demonstrated its capability as a high-performance component for small gas turbine engines, its use has been relegated to lower turbine-inlet-temperature cycles due to insurmountable problems with respect to the manufacturing of radial turbine rotors with internal cooling passages.
