Worlds first 9 bladed prop

Flight test program started

Atting, March 2019 - The world’s first 9 bladed prop started its flight test program on March 11th,2019 and initial results are very promising, as reported by German pro manufacturer MT-Propeller. The company’s press release continues:

“Function, handling and operation of the aircraft is like those props have been in service already for years.



The world’s first 9 bladed prop, made by MT-Propeller, has started its flight test program.

This new development is made for low noise, high performance future airplanes driven by electric powered engines, turbine engines or geared piston engines for propellers with low RPM.

Depending on propeller driven airplane designs, top speeds of up to 430 KTAS are realizable with such a installation, by reducing at the same time the fuel consumption to a turbo prop from a jet.

MT-Propeller proves with this milestone that the innovation in propeller driven airplanes is just at the beginning.

Flying a Jet comfort airplane powered by props combined with the lowest fuel consumption becomes a near future.
