Earthrounder Stefan Mommertz and his way around the world.


Earthrounder Stefan Mommertz with his airplane
September 03, 2019




In August 2018 Stefan Mommertz startet his way around the world with his Cessna 185 equipped with a 3-blade MT-Propeller MTV-9 on the airport Würselen-Merzbrück. Heading West the first leg of his flight led him over Iceland, Greenland, Canada, Alaska, Siberia, Japan and the Philippines, where he had to leave his Cessna for a while and went back to work.

Four months later he started in Borneo for the second leg of his flight around the world. The route followed the South China Sea to Singapur and West Malaysia over the Gulf of Thailand to Bangkok and Chiang Mai to Bangladesh, India, Pakistan, Oman and Abu Dhabi.

The last leg of his way around the world in spring 2019 led him over Jordan, Aqaba, Alexandria, Kreta, Italy to Lucerne in Switzerland, where he picked up his mother for joining him on the flight back to Germany.

He flew 33,000 Kilometers in three stages and visited 4 continents and 28 countries. His total flying time was about 32 days.

Congratulation to Stefan Mommertz for his great success.

Worlds first 9 bladed prop started the flight test program


Testairplane Cheyenne with 9-blade MTV-39
March 13, 2019



Worlds first 9 bladed prop started the flight test program on March 11th 2019 and initial results are very promising.

Function, Handling and Operation on the aircraft is like those props have been in service already for years.

This new development 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 with props combined with the lowest fuel consumption becomes a near future.
