Doblhoff's "pressure-jet rotor" concept involved piping high-pressure air from a compressor out to the rotor-blade tips, where it was mixed with fuel and burned in combustors.
The results indicated that in the two-blade impeller, the fluid mainly flowed along the suction side, the velocity is very small on the pressure side, and a typical jet-wake flow has been observed.
